What is a recall, really?
A recall means the government made the manufacturer admit a safety defect — and the fix is free at any dealer, forever, even for used cars. Recalls range from a software update to "the steering wheel can detach," so read the danger line on each one. Buying used? Ask the seller for proof each recall was completed, or have a dealer run the VIN. Recalls also have a quieter cousin worth reading: technical service bulletins.

Raw count — best-sellers naturally log more complaints than rare cars, so judge it against the peer comparison below, not on its own.
Why don't we show complaints per vehicle sold?
Because no official source publishes sales counts per model — that data is sold by private firms, and the free numbers online are guesses. A rate built on a guessed denominator is a guess wearing a lab coat, so we refuse to show one. Instead we show comparisons where fleet size cancels out or is disclosed: the same model across its own years, the crash/fire severity mix, and the peer ranking below — each with its methodology attached.

Check electric system popped up. DTC: P1AD300 Critical hybrid/ev battery system fault involving abnormal cell voltage deviation 9,902 miles
EV system not working on car with 8k miles on it. Dealer backed up and cannot offer rental car. This is a safety issue for me . This is a KNOWN issue for Hyundai and they are not recalling and their dealers are not equipped to resolve quickly.
Systemic failure of the electrical architecture and Integrated Charging Control Unit (ICCU) resulting in a sudden, catastrophic loss of motive power. Over 14 months of ownership, this vehicle has suffered four distinct, electrical and charging failures. On June 6, 2026, the vehicle experienced a total ICCU failure. All lights in the car went dark and lost all power without warning, creating an immediate and life-threatening hazard to myself . The vehicle had to be towed. Three prior repair attempts for charging and 12V battery failures were made by the dealer/. They replaced the ICCU, the car currently runs.. The replaced ICCU has not been redesigned and as a result the car is unsafe to take out on the highway or on a long drive.
Failure of ICCU and high voltage fuse. Known issue in this vehicle. 2022-24 have been recalled. 2025 needs to be recalled. Warning on dash when it occurred, then 12V battery died. Undrivable. Towed in and repaired under warranty by dealer. But apparently it can happen again because Hyundai doesn’t know how to permanently address the problem.
During a family road trip, my 2025 Hyundai Ioniq 5 (~9,000 miles, less than one year old) suddenly showed red "Check Electric Vehicle System" and 12V battery warning lights and then completely lost power. The 12V system failed entirely - the vehicle could not be driven or shifted, and the doors and the rear hatch could not be locked or unlocked. It had to be flat-bedded to a Hyundai dealer because it was completely inoperable. The dealer diagnosed a failed ICCU (Integrated Charging Control Unit) and a blown ICCU safety fuse (fault code P1A9096) and is replacing both under warranty; the component is available for inspection. The ICCU converts high-voltage battery power to charge the 12V system; when it fails, the vehicle loses all electrical power and drive capability. The warning lamps appeared immediately before total power loss, with no prior symptoms at the last scheduled service. This is a known, safety-critical failure on this platform: a sudden, complete loss of power can strand occupants and, if it occurs while driving, cause loss of motive power - a serious crash risk. My vehicle was stationary when it failed, but the same failure at speed would be extremely dangerous. I have video evidence of the car completely bricked out.

SAFETY DEFECT REPORT: 2025 HYUNDAI IONIQ 5 HIGH-VOLTAGE BATTERY FAILURE On Sunday, July 5, 2026, at approximately 24,000 miles, the vehicle suddenly displayed a critical dashboard safety alert notifying me of an electrical propulsion failure and explicitly instructing me not to drive the vehicle. The sudden failure entirely disabled the vehicle's driving power and compromised its operational safety. The vehicle was removed from my possession via a flatbed tow on Wednesday, July 8, 2026, and delivered to Southern States Hyundai. On July 11, 2026, the dealership service technicians diagnosed a total high-voltage traction battery pack failure. The dealer opened Repair Order 9651579, and Hyundai Corporate approved a full warranty replacement of the $28,000 battery system. The vehicle remained out of service due to this safety defect for 21 cumulative days until the component replacement was completed on July 29, 2026.
Systemic failure of the electrical architecture and Integrated Charging Control Unit (ICCU) resulting in a sudden, catastrophic loss of motive power. Over 14 months of ownership, this vehicle has suffered four distinct, electrical and charging failures. On June 6, 2026, the vehicle experienced a total ICCU failure. All lights in the car went dark and lost all power without warning, creating an immediate and life-threatening hazard to myself . The vehicle had to be towed. Three prior repair attempts for charging and 12V battery failures were made by the dealer/. They replaced the ICCU, the car currently runs.. The replaced ICCU has not been redesigned and as a result the car is unsafe to take out on the highway or on a long drive.
The car entered a failed ICCU state (not confirmed until the car was looked at by Hyundai at the dealership) while I was driving down to Ano Nuevo regional park. Received a warning on the dash that said that electrical system has failed and to pull over. It restricted me from going over 10 mph on Highway 1 and I eventually pulled over the side of the road and got towed to the dealership. The car is home with me now but I do not feel safe driving this vehicle after all of the reports of ICCU failures. I am very concerned this will happen again and in a more dangerous situation. I was also stranded by this car in March 2026 with a dead battery.
When I started the car at 10pm , a loud pop was heard and warning lights on the dashboard indicated an electrical problem. I turned off the radio and anything extra that could use up power; during the next 45 minutes I took surface streets instead of the freeway to drive 22 miles back home and speed was limited to 40 mph. The next day the same warning lights were on the dashboard and speed was limited to 20mph; car lost power after 1 block. Car was towed to the dealer, where an ICCU failure and blown fuse in the engine was diagnosed by dealership and replaced.
Car has only 3307 miles and incurred a DTC P1A9096. This meant the vehicle only had power from the 12 volt battery, not traction battery. Luckily, the event happened 3 miles from home and we were able to just make it. Next day upon calling for flatbed tow service, the car generated an additional DTC P05616. 12 volt battery was exhausted and nothing functioned on the car. Had to then call for a different tow truck with dollies. The failure of the ICCU (Integrated Charging Control Unit) was a cause for recall on earlier year's models. This is a major safety issue as failure of the ICCU leaves you stranded with an inoperable vehicle where you cannot even lock the doors. Currently, the vehicle is at the dealer (Lithia Hyundai of Anchorage) for repair.

I was slowing down, actively pressing the brake pedal to bring the vehicle to a full stop. As the car decelerated to what my senses and perception registered as a full stop, I pressed the “P” (Park) button while keeping my foot on the brake pedal. I felt the physical click of the “P” button under my thumb while still holding the brake, and my mind registered that the vehicle had successfully transitioned into Park. Before turning around, I visually confirmed that the vehicle had come to a complete stop. Believing it was fully secured in Park, I turned my head to check on my child in the back seat and naturally released the brake pedal completely. However, the system had actually rejected my command. I assume that the vehicle likely still had a small amount of speed at the exact millisecond I pressed the button, and the computer automatically blocked the “Park” command and kept the car in gear. Because an electric vehicle operates in almost complete silence, with no engine noise or vibration to indicate that it is still in gear, there was no auditory or physical cue to alert me that the car was moving when I released the brake. While my attention was turned toward the back seat for a few seconds, the car quietly began to creep forward, leading directly to the collision with the car in front of me. Following the accident, I found that the vehicle produces slightly different sounds when Park is rejected and when it is successfully engaged. However, the owner’s manual describes only the dashboard message and does not describe these sounds or explain how to distinguish them, so their meanings may be learned only through the failure. At the time of the incident, I was not familiar with the distinction between these two sounds. Because my brain processed the physical press of the button as a successful action, and I had visually confirmed that we were not moving, my focus immediately shifted to my child. I was entirely misled by the digital interface.
During a family road trip, my 2025 Hyundai Ioniq 5 (~9,000 miles, less than one year old) suddenly showed red "Check Electric Vehicle System" and 12V battery warning lights and then completely lost power.

Vehicle was parked in closed garage overnight. In the morning I tried to start the car and it was unresponsive. key fobs, digital keys, NFC cards none of them were able to open the car. Used a physical key to open the door, and then tried to turn the car on, nothing worked all screens remained black and car was unresponsive. AAA confirmed that the 12V battery was fully dead. When they jumped the vehicle we heard a pop in the car, which is a known ICCU failure indication. The car still turned on and was drivable. I got it to the dealership safely and they confirmed that the 12V battery was fully dead and car only turns in if jumped. They also confirmed that the ICCU had a failure as well and they are going to need to replace the entire battery pack/ICCU assembly.
Car charged as scheduled overnight 3/28/26 but was dead the morning of 3/29/26 and when it was jumped gave error "Battery overheated, please stop and exit vehicle" and "check electrical system" - vehicle has been in shop for 16 days, no diagnosis except that it "probably" needs a HV battery.
On April 1, 2026, my 2025 Hyundai IONIQ 5 experienced a cascading electrical failure. The vehicle first displayed a warning about a problem with the on-board charger, followed shortly by an alarm and the 'Stop Vehicle and Check Power Supply' warning with a red 12V battery indicator, rendering the vehicle unsafe to drive. Had I been on the freeway this would have been extremely dangerous. My Bluelink diagnostics history confirms three fault codes from that date: P1A9096 (ICCU fault, Electric Vehicle / Air Flap system, still Open as of 4/3/2026), and P056216 (Voltage Regulation fault, Hybrid Control system, reported twice), consistent with a cascading ICCU failure causing 12V system collapse.
Real owner reports filed with NHTSA (showing 5 of 23):
The driver attention warning feature is defective and often requires you to take your eyes off the road and stare at the DAW sensor in order to eliminate the car's constant "attention" warnings. Even while looking straight ahead while driving, the DAW is often erroneous and will disengage safety features (e.g., lane keeping assist, adaptive cruise control, etc.) because the DAW erroneously thinks that the driver is not paying attention. As another example, if you are driving uphill/downhill or on a curved road and are looking at the road ahead of you at a slight angle, the DAW will erroneously report that the driver isn't paying attention. The system will then disable the cruise control and lane keeping assist, creating a hazardous situation. Alternatively, the driver can look DOWN (not looking at the road) at the DAW sensor and stare at it until the car reacts. This takes your eyes off of the road and creates hazardous situations. As someone who wears prescription glasses, the problem is even worse. I cannot set a comfortable seat/steering wheel configuration where the DAW can "see" through my prescription glasses. If I want to drive in my normal position, I either need to take my glasses off or turn off the safety features (e.g. lane keeping assist and adaptive cruise control) in order to drive. Hyundai is well aware of this problem and it exists across much of the Hyundai and Kia platforms. Dealerships say that the car is working as intended. In reality, the defective DAW system creates more risk and contributes to a significantly less safe ride (as I'm constantly taking my eyes off the road to stare at the darn sensor).
The vehicle’s driver monitoring / Forward Attention Warning system repeatedly gives false inattentive-driver warnings during normal highway driving, even when I am actively watching the road and driving normally. The system does not appear to function reliably with ordinary sunglasses and common driving conditions. The issue happens frequently when wearing sunglasses. The system incorrectly determines that I am not paying attention, despite looking directly ahead at the roadway. When this happens, Highway Driving Assist and lane-centering functions may disengage or become unavailable. This occurs in normal daytime driving conditions and appears overly sensitive to environmental factors, including reflections, lighting conditions, and driver seating position. I typically receive multiple false warnings during a single drive. This is a significant safety concern because: Driver assistance features can unexpectedly disengage during highway driving. The repeated false warnings are extremely distracting and can result in drivers ignoring or becoming desensitized to alerts. There are many similar owner reports online describing the same issue with Hyundai’s driver-monitoring system. Hyundai has issued a technical bulletin describing the problem but has made no indication that it intends to fix this significant flaw. My vehicle's software is fully up-to-date.
The emergency steering will engage at random times. The car makes a loud noise, a light on the dashboard illuminates, and the car will try to drive into another lane. This happens at least once a week, and it has never happened when there was another car around, so I wasn't about to get into a collision. It has happened when there is construction and the lane markers are unclear, when the road is a little wet and other times I can't explain. I have always been able to shove it back into the lane I want to be in, but this also seems incredibly unsafe. It could drive me into any sort of situation involving other cars or off the edge of a road. I've Googled and I am not alone in experiencing this problems. I reported this twice to Hyundai customer service.
A collision occurred when the vehicle failed to detect a stationary stop‑sign pole directly in front of it. The forward collision‑avoidance system did not provide any braking assistance or intervention before impact. The vehicle is equipped with the full safety and driver‑assistance package, including camera and radar‑based collision‑avoidance features, so the system was expected to recognize an obstacle in the vehicle’s path. The failure created a safety risk because the vehicle did not respond to an object directly ahead, and the driver relied on the advertised safety features to help prevent or mitigate such collisions.

Our 2025 Hyundai Ioniq 5 has been sitting unrepaired for almost five months due to a complete lack of availability of an essential replacement part (front bumper lower molding part number 86569PI000). The car was involved in a minor collision on [XXX], and although no one was hurt and the airbags did not deploy, the vehicle has remained unrepairable and inoperable. The car sensors can not be calibrated without this part, thus affecting all front sensors of the vehicle. Both the Hyundai-certified repair facility and our insurance company have confirmed that the necessary part is on national backorder with no estimated date of arrival, despite extensive efforts to source it — including looking on eBay and through nationwide networks. This was also confirmed by Hyundai Customer Support with whom we opened case [XXX]. The part involved is necessary for proper calibration of front sensors of the vehicle. We are continuing to pay on the lease while the car sits undriveable and depreciating. This has placed a major financial burden on us and raises broader safety concerns. Hyundai is apparently unable or unwilling to supply parts for its current-year models, which may compromise the safe restoration of structurally- or electronically-damaged vehicles. We respectfully request that NHTSA investigate Hyundai’s inability to supply safety-critical parts for its 2025 models, and determine whether this systemic delay poses a risk to consumers and undermines post-collision safety standards. The repair shop is Advanced Collision Repair in Escondido, CA, 760-741-7565. The shop’s manager is John McLure.

The Moon Roof glass, which is not designed to open, developed a non-impact, or stress fracture. Since it is not supposed to open, the glass is a structural part of the vehicle. It was not cracked when I first took possession of the vehicle, and since I did not open the interior screen all winter, I never noticed the crack. I reported it to the dealer, but it did not take responsibility or offer a replacement.
Heard a pop sound, drove three-mile back to house, with car throttled speed to 20 MPH on 35 MPH roads. Leased 2025 Ioniq 5 at 4553 mi. Once back, completely died, vehicle wouldn't lock, start or move. We had vehicle towed to Dealer (20 miles away). No warning lights, no notices. The vehicle needs a new ICCU, the associated fuse and a new 12-volt battery. This is a known recall for the Ioniq 5 2020-2024. When leasing this 2025, we were assured the problem was fixed on the 2025 - Clearly that is not the case. This is ridiculous- it should be a recall and fixed proactively rather than a crash potential hazard for the driver.

On April 20th while parking the vehicle suddenly had a power surge crossing over multiple curbs and across a parking lot and landscaped areas and hitting a tree. The vehicle refused to brake and the driver airbag never deployed.
For the HYUNDAI Ioniq 5 XRT, the ICCU, fuse and perhaps hybrid battery malfunctioned. We were in a disabled car on a 4 lane highway with traffic: On February 10, 2026, as we drove out of our home we heard a loud pop. As we got out onto a large 4 lane road near our house, the notice “Check Electrical System” came on and the car’s power was drastically reduced. We made a U turn and drove (20 mph) back to our driveway. We were fortunate that this was mid-day and the road was relatively clear. Normally this is an extremely busy road with traffic moving at 40-50 mph and we would have had great difficulty even pulling out to the side -- as there is only marginal side space on this road. Hyundai has confirmed to us that the ICCU and a related fuse failed. They also think the hybrid battery is also involved and they are testing to confirm that. We had no warning at all -- except for the electrical warning that came on as the car's power was reduced. The car had charged normally and had had no warning signals/signs at all.
Check electric vehicle system light came on and power slowly diminished which meant the car was unable to sustain highway speeds. Had to be towed to dealership.
Real owner reports filed with NHTSA (showing 5 of 16):
The driver attention warning feature is defective and often requires you to take your eyes off the road and stare at the DAW sensor in order to eliminate the car's constant "attention" warnings. Even while looking straight ahead while driving, the DAW is often erroneous and will disengage safety features (e.g., lane keeping assist, adaptive cruise control, etc.) because the DAW erroneously thinks that the driver is not paying attention. As another example, if you are driving uphill/downhill or on a curved road and are looking at the road ahead of you at a slight angle, the DAW will erroneously report that the driver isn't paying attention. The system will then disable the cruise control and lane keeping assist, creating a hazardous situation. Alternatively, the driver can look DOWN (not looking at the road) at the DAW sensor and stare at it until the car reacts. This takes your eyes off of the road and creates hazardous situations. As someone who wears prescription glasses, the problem is even worse. I cannot set a comfortable seat/steering wheel configuration where the DAW can "see" through my prescription glasses. If I want to drive in my normal position, I either need to take my glasses off or turn off the safety features (e.g. lane keeping assist and adaptive cruise control) in order to drive. Hyundai is well aware of this problem and it exists across much of the Hyundai and Kia platforms. Dealerships say that the car is working as intended. In reality, the defective DAW system creates more risk and contributes to a significantly less safe ride (as I'm constantly taking my eyes off the road to stare at the darn sensor).
While using Highway Driving Assist/Lane Following Assist on Interstate highways, lane markings frequently disappear on overpasses and in construction areas. When this occurs, lane-centering assistance silently disengages. The only indication is a small dashboard icon changing color. There is no audible warning, steering wheel vibration, or other prominent alert. The vehicle may begin drifting before the driver realizes steering assistance has been lost. Observed repeatedly on Massachusetts highways, including I-495 and I-290. This creates an unexpected and serious safety issue, potentially resulting in an accident. I had this happen during a recent trip, and multiple times the car wandered towards an adjacent lane. It caused me to lose confidence in the system, and to maintain constant vigilance, gripping the wheel tightly at all times. Had I not done so, I’m sure I would have had an incident. Who watches the dashboard all the time? The driver's eyes are supposed to be on the road ahead, especially when approaching an overpass. Had they incorporated an audible or tactile alert, this would have greatly increased the driver’s awareness and potentially avoid a crash. Since the system obviously knows when it has disengaged, it would be a simple matter to implement this. My preference would be steering wheel vibration.
The Driver Attention Warning system fails every time I put the car in Cruise Control. I have adjusted my seat and the steering column but no relief. I have removed my hat and sunglasses with no relief. I have my hands at 8 and 4. The DAW IR tracking causes a visual warning in the dashboard and then a horrific cacophony if I try to ignore the warning. Two weeks ago an OTA was downloaded which purported to improve the sensitivity of head movement. It is not improved, if anything it is quicker to warn. In settings I turned off the Lane Following Assist and Driver Warning Assist each time I start the car. This does nothing to impact the failure of the DAW. The lack of Cruise Control on long drives causes fatigue and does not help with safety. The constant harassment of the DAW warning does not lend to safer driver. This whole system is intrusive and not making driving safer.
The vehicle’s driver monitoring / Forward Attention Warning system repeatedly gives false inattentive-driver warnings during normal highway driving, even when I am actively watching the road and driving normally. The system does not appear to function reliably with ordinary sunglasses and common driving conditions. The issue happens frequently when wearing sunglasses. The system incorrectly determines that I am not paying attention, despite looking directly ahead at the roadway. When this happens, Highway Driving Assist and lane-centering functions may disengage or become unavailable. This occurs in normal daytime driving conditions and appears overly sensitive to environmental factors, including reflections, lighting conditions, and driver seating position. I typically receive multiple false warnings during a single drive. This is a significant safety concern because: Driver assistance features can unexpectedly disengage during highway driving. The repeated false warnings are extremely distracting and can result in drivers ignoring or becoming desensitized to alerts. There are many similar owner reports online describing the same issue with Hyundai’s driver-monitoring system. Hyundai has issued a technical bulletin describing the problem but has made no indication that it intends to fix this significant flaw. My vehicle's software is fully up-to-date.

I was driving on a busy highway at a high but legal speed. For a few seconds the vehicle appeared to reset. I lost control and the screen went blank. It was a miracle I did not hit another vehicle. I contacted the dealer and they stated unless it was happening frequently - there is nothing they could do. I spent hours on the phone with the dealer attempting to schedule an appointment, they stated their EV person was not available. I contacted Hyundai customer service. They ignored me for months. They assigned me a contact person - but she would never return my calls. I called the main support number and started over after several months. This representative collected all my info - title, purchase receipt, etc - but then closed my case after a couple calls. They totally ignored the concern.
I was driving my vehicle on a freeway with 3 passengers when i heard a muffled pop or thud from behind me. A rear passenger confirmed that it came from beneath the rear seat towards the left side of the car. The vehicle speed immediately dropped to less than 40 mph and a warning message appeared on the dash "Check electric vehicle system". I later noticed a red battery icon appear on the left of the dash. I pulled over after leaving the freeway and attempted to resolve the issue by turning off the car, then restarting it. The notice and red battery icon still appeared. I feel that this sudden reduction in speed is a safety issue because I could have been driving at a higher speed (65-70 vs 45-50). Following cars may not have been able to stop in time, or I cuold have been forced to attempt to get off the road by entering lanes with vehicles travelling at a much faster speed. I was about 5 miles away from home on the start of a 400 mile trip so decided to turn around. Back at home I discovered that a new DTC code had been thrown during or after this event - P1A9096. I transferred to another person's cart to complete the trip, and on return arranged for the car to be transported to a manufacturer recommended dealership to check the issue. The Dealership service department conducted diagnostic tests and determined that the issue was caused by an ICCU failure. The have placed an order for a replacement ICCU unit and fuse. Prior to this event there had been no dash light warnings or trouble codes thrown.
ICCU unit of the car short circuited right in middle of driving and caused the car to go in "limp mode". Sudden pop noise and slowdown created situation where car could be rear-ended. The part has already caused recall for prior model years, but model year for my car is not included in the recall. Based on internet search it is a continued and widely prevalent issue, manufacture has not done enough to fix this and a recall needs to add new model years. Additionally, the parts are backordered and there is no immediate fix.

The Forward Attention Warning system in the refreshed 2025 Ioniq 5 gives constant false positives for both my wife and myself when we are driving the car. With Hyundai's HDA and lane keep active, the system keeps chiming, claiming that the driver is not looking at the road when we are. In fact, the calibration is so poor that it is a safety issue. The constant random warnings are very distracting, and sometimes the system does not recapture your eyes before timing out and hard braking the car on the highway. This is really unacceptable and a safety issue that I'm surprised Hyundai thought it could release. Lots of evidence of other owners with this problem on the Internet: [XXX] [XXX] and many others.

The emergency steering will engage at random times. The car makes a loud noise, a light on the dashboard illuminates, and the car will try to drive into another lane. This happens at least once a week, and it has never happened when there was another car around, so I wasn't about to get into a collision. It has happened when there is construction and the lane markers are unclear, when the road is a little wet and other times I can't explain. I have always been able to shove it back into the lane I want to be in, but this also seems incredibly unsafe. It could drive me into any sort of situation involving other cars or off the edge of a road. I've Googled and I am not alone in experiencing this problems. I reported this twice to Hyundai customer service.
Car battery completely failed on a busy road.

The Moon Roof glass, which is not designed to open, developed a non-impact, or stress fracture. Since it is not supposed to open, the glass is a structural part of the vehicle. It was not cracked when I first took possession of the vehicle, and since I did not open the interior screen all winter, I never noticed the crack. I reported it to the dealer, but it did not take responsibility or offer a replacement.
My Ioniq5 has experienced a recurring water leak that has repeatedly exposed the left rear seat belt and seat belt retractor to large amounts of water. I noticed recently that after it had rained the left back seat belt was soaked and dripping water when pulled out. After fully pulling out the belt as far as it would go it was clear that the water had fully soaked the belt and retractor. It is unclear when this started or how long this has been occurring, as there was no warning or other indication that there was a leak until the belt happened to be put on soon after it had rained. I am uncertain if this poses an actual risk to the function of the seat belt or seat belt retractor. However, even though it is unknown if the water intrusion limits the seat belt's function, there is a perceived risk that this could corrode or degrade the function of the internal components due to the repeated water exposure. The car was taken to the dealership twice. The first time they claimed they were unable to repeat the issue. However, days later it rained again and the belt and retractor were again soaked. After the second return to the dealership they were able to confirm a leak in the glass roof of the vehicle that was allowing the intrusion to the seat belt and retractor. The car is still currently at the dealer awaiting repair for the water leak with an unknown timeline
Went to open the door and hand slipped off the handle and it snapped back crushing my finger. Nail turned black and finger was mangled for a few days, very unsafe door handles .

Ioniq 5's yellow air bag wire/harness underneath driver seat has design flaw, many other owners are noticing. In my case the cables are touching the floor, it's a hazard.
Ioniq 5 is known to have a loose and possibly dangling wire underneath the driver seat. This wire is often uncovered and unshielded, and is susceptible to becoming damaged due to the automatic seats and adjustments. This wire directly operates the airbag and if damaged loses all functionality. Hyundai is not covering any damage to this wire under warranty, and this poses an immediate threat to anyone driving their vehicle.

I need to report a serious vehicle safety concern involving a catastrophic front-right tire failure at highway speed. I am requesting a Hyundai case number and preservation of all physical evidence. Please preserve the failed tire, detached tread assembly, bead remnants, wheel, TPMS components and all service records. These items constitute material evidence necessary to determine whether the initiating cause was underinflation, rapid pressure loss, mounting damage, belt separation, bead failure or a manufacturing defect. The vehicle had been returned after approximately one month at a repair facility. After the incident, the three remaining tires measured 41, 35 and 35 psi, while the vehicle placard specifies 38 psi. The pre-failure pressure of the destroyed tire is unknown.

I purchased this vehicle on [XXX] in the state of Colorado and had to drive it home through a winter storm to California. While driving home the vehicle on multiple occasion the vehicle flagged driver assist disabled or inoperable errors due to "radar blocked" stopping and checking the front of the vehicle I found that the car had no snow or ice build up on the exterior of the bumper, and there was no reason that all the driver assist and even safety features like Automatic Emergency Braking had been disabled. In addition while making this drive home, the vehicle passenger side wiper failed catastrophically. Over a 30 day process the local dealer replaced the broken wiper blade motor, and determined there was nothing wrong with the internal Auto assist system, even stating there were no DTC/ or error codes present. I provided them with images of the errors and millage, but nothing further could be done because they could not "replicate the issue" and no codes are being stored. At around 1430 miles I was driving in dry, warmer weather (around 50 degrees) when another error flashed on my screen again. I brought the vehicle back to the dealership for diagnostics, where they have yet to determine the issue again. They've stated no DTC or error codes are present, and they can not reproduce the issue so the vehicle is operating "normally and designed". I have been working with Hyundai Consumer Affairs during this entire time to help speed this process along, they have no answer other than, if the error appears again, do not turn of the vehicle, drop everything your doing in your life and bring it directly to the dealership for diagnostics (even if its active safety features are not working while your driving it).

How to read these stars
These come from the government physically crash-testing this vehicle — front, side, and rollover — and scoring it 1 to 5 stars. Ratings are per body style, so a sedan and its coupe twin can differ. If a vehicle shows no rating, it usually means the government never tested that exact configuration — untested is not the same as unsafe, and we'll never blur that line.
