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.

Backing vehicle out of driveway and went to engage brakes and they did not engage. began rolling backwards down street with steep grade. Kept stepping on brakes with no response. Had to turn into a parked vehicle to keep from rolling down steep grade and potentially off a substantial cliff. Happened today and dealership said that it may be because the "battery for the brake" had not received a charge from the main battery. Very dangerous and never disclosed. If I had not taken evasive action I could have easily been killed. Car is being dropped off at collision center today but is available for inspection. There were no warnings or other symptoms.
This is an EV . We use the regenerative braking to slow down. This car has both a front and rear dash cam. The car is about two and a half years old and has about 20,800 miles. We were approaching a red traffic light with several vehicles stopped in front of us. My partner was driving and had slowed to 8 mph, with her foot off the accelerator, advancing slowly towards the car in front of us when the vehicle experienced unanticipated, rapid acceleration. With quick reflexes, she was able brake hard and avoided a collision. Ten minutes later she was parking at our house, going 4 mph and it did it again, coming within four feet of the building. Neither time was she touching the accelerator, but the car accelerated like the accelerator was pressed to the floor. This is very dangerous.
On June 13, 2026, my 2024 Hyundai Ioniq 5 experienced a sudden and dangerous propulsion failure while in active motion. The vehicle had approximately 9,447 miles on it and was at 58% battery charge at the time of the incident. The vehicle was leased in January 2025 and has been serviced exclusively at the Hyundai dealership. While driving with two occupants, the vehicle abruptly lost all ability to accelerate. The dashboard displayed a critical warning: “Stop vehicle and check power supply” along with a red battery icon. This failure occurred without warning and immediately placed us in danger of being struck by surrounding traffic, as the vehicle could no longer maintain speed or respond to throttle input. I was able to coast the vehicle off the roadway. Shortly after stopping, the vehicle issued an additional warning stating that auxiliary functions were draining the battery. Within moments, the vehicle shut itself down completely. This left both occupants stranded in extreme heat (over 100°F) with no air conditioning, no ventilation, and no ability to restart or power the vehicle while waiting for rescue. This created a serious risk of heat-related medical distress in addition to the initial roadway hazard. The vehicle’s complete loss of propulsion followed by a full electrical shutdown represents a severe safety defect. At no point should an electric vehicle with more than half a charge and fewer than 10,000 miles lose propulsion during active driving or shut down all systems while occupants are inside. This incident posed a significant risk of collision, injury, or heat-related harm. I am requesting that NHTSA investigate this failure mode, as it may indicate a broader defect affecting the propulsion or battery management systems of the Hyundai Ioniq 5. The vehicle is currently at the Hyundai dealership undergoing diagnostics and they confirmed they had difficulty jumping it to move it from where the tow truck had parked it on arrival.
I am writing regarding a very serious and frightening safety incident involving my 2024 Hyundai IONIQ 5. While driving through a busy intersection in California, the vehicle displayed the warning message: “Stop vehicle and check power supply.” Within approximately one minute of that warning appearing, the vehicle completely lost power and became inoperable in the middle of the intersection. The shutdown occurred without warning and created an extremely dangerous situation. The vehicle’s hazard lights would not function because the car appeared to be entirely without power. Traffic continued moving around me while I was stranded in the intersection, and I genuinely feared that another vehicle could collide with me. I ultimately called 911 because the situation was unsafe and I could not move the vehicle. Police responded and directed traffic until the vehicle could be towed. Hyundai dealership had the vehicle for 22 days and diagnosed it as a faulty ICCU (Integrated Charging Control Unit) which they replaced for no charge. This incident has caused me to lose confidence in the safety and reliability of this vehicle. A complete loss of propulsion in active traffic — especially accompanied by failure of the hazard system — is an unacceptable safety risk. I no longer feel safe driving this vehicle. Hyundai of America would not let me cancel the lease early due to safety concerns.

My wife was parking the 2024 ioniq and it lurched forward at a high rate of speed and slammed into another car parked in our driveway and drove that vehicle through our home garage door. She feels certain that her foot was on the brake, but even if she accidentally slipped and appleid the brake the forward collision system should have prevented the accident additionally the impact occurred with such force it is unlikely due to human error as it pushed our very heavy 4Runner back 3 feet and thorough a closed garage door.

I lease a 2024 Hyundai Ioniq 5 AWD. Prior to a planned trip, the vehicle displayed an electrical system warning. I contacted the dealership and was advised to bring it in. While driving approximately 5 miles to the dealership, the vehicle lost all power including hazard lights, leaving me stranded on a busy road. I contacted roadside assistance and the vehicle was towed to the dealership. The dealership confirmed the failure was caused by the ICCU (Integrated Charging Control Unit). The repair took approximately two weeks. The vehicle was unavailable during this time, requiring a rental car. Hyundai partially reimbursed rental costs but did not compensate for other losses incurred. The ICCU failure is a known widespread issue affecting the entire Hyundai/Kia E-GMP platform across multiple models and model years. A dedicated owner community tracking these failures can be found at [XXX] . The sudden and complete loss of vehicle power including safety systems such as hazard lights while in traffic represents a significant safety risk to the driver and other road users.

As I began a drive cycle, I heard a pop sound and received the “check electric vehicle system” warning associated with ICCU failure. With ICCU failure, if I had continued to drive the 12V battery would have run to zero and the car would have died completely. Vehicle goes to dealer tomorrow for confirmation.
2/28/26 Driving home, heard a loud pop, notice is on the dash say check vehicle electrical system. Vehicle begins to slow down and eventually die. Called the manufacturer and had it towed to the dealership. The ICCU had failed.

ICCU failure. Common problem but Hyundai seems to have no fix despite it happening for years now.
Received multiple "Check Vehicle Electric Systems" on a drive which went away and then got into the car, turned it on, shifted into drive, and heard a pop from bellow before moving at all and the car went into Turtle Mode and blasted warnings. The car completely died with zero power leaving it stranded in sub freezing temperatures and unable to lock the car or open the lift gate to access the trunk area. Eventually it was towed to the dealership and was diagnosed to have a faulty ICCU which took 5 weeks to replace.
While driving I received the infamous "Stop vehicle and check power supply" warning, and it was then inoperable, needed a tow to the dealer for ICCU replacement. I can't believe you terminated your initial investigation into this in 2023 because they did a recall (which my car received). That recall did not fix the issue. It is March 2026 and Ioniq 5 and other models with the same electric system are dying on the road at the same rate as before. There is a large percentage of failed cars, and every failure is dangerous. This is a huge safety issue, and is not receiving adequate oversight by the NHTSA.
I was merging onto the highway. I got a warning that I needed to check my electrical system. I was able to back down the highway ramp and park on a side street. Within 20 minutes the car was fully dead and AAA needed to tow it to the dealer. The dealer confirmed that the ICCU needs a replacement. My family is lucky this happened in a place we could safely get to a side street. Had it happened 5 minutes later we would have been stranded on the highway with 2 small children.

The car engine shutdown mid drive. One minute before the complete stop, the car was stalling every 20 sec or so, then the acceleration stop responding to the drive pedal. The car was gliding to a stopping point. The "Engine " warning was on the display. Afterward, the car was towed to the Earnhardt Hyundai North Scottsdale, where the service center could not recreate the problem. They concluded that is a non issue since they did not observe the same issue during the test and diagnostic.

For the second time, the integrated control unit, ICCU, has failed to this is AFTER being replaced under the recall. The recall solution has not fixed the problem, and is a fake bandaid on a problem that means cars will totally stop working in the middle of the road. This is totally unsafe and unacceptable.
I was driving and the car gave an electrical system warning, slowed, and thereafter would not go above about 20mph. Fortunately this happened on a local, low speed limit street. I'd rather not think about what might have happened if this had happened on a highway. The Integrated Charging Control Unit (ICCU) is no longer working as it should. The problem has been confirmed by the dealer/manufacturer service station.
The vehicle experienced a sudden failure of the 12V battery while on the road. The car stopped completely and became inoperable. At the time of failure, there were no tail lights or proper warning indicators working, which created a very dangerous situation, especially in traffic. I was stuck on the road for about one hour waiting for a tow truck. During that time, other vehicles were honking and passing by, increasing the risk of an accident. The vehicle had to be jump-started before it could be moved. Details: What component failed: The 12V battery system failed unexpectedly. The vehicle is available for inspection upon request. Safety risk: Loss of power caused the vehicle to stop on the road with no tail lights, putting my safety and others at serious risk. Reproduction/confirmation: Issue was temporarily resolved with a jump-start, but this is a known issue reported by other owners as well. Inspection: The vehicle has not yet been inspected by the manufacturer or dealer after this incident. Warnings/symptoms: There were no clear warning lights or messages before the failure. The issue happened suddenly without notice.

1. Brake Failure: recently when my brakes stopped responding while driving.The pedal went all the way to the floor, and I barely managed to stop the car. 2. Knocking sound when braking: I started to notice a clunking/knocking sound that would occur when braking and just about coming to a stop.

This is the second time the ICCU failed. The car is waiting for a full EV battery replacement. The first time the failure happened on 12/11/25, at 9,165 miles, the alert happened just before the car came to a full stop as we were driving along the road near our house, it was very difficult to steer, we were sort of stopped in the road and had to get it towed. The second time the alert came on 4/16/26 and we were able to get it to the dealer.
While driving northbound on US-280 freeway, the vehicle experienced sudden deceleration with maximum speed limited to approximately 40 mph. The dashboard displayed a "Check Power Supply" warning. The vehicle required a tow to the dealership. Dealer diagnosis indicates likely ICCU (Integrated Charging Control Unit) failure. This is a known issue affecting multiple Hyundai Ioniq 5 vehicles, with numerous consumer reports of the same failure mode. The sudden loss of propulsion at highway speed created a significant safety hazard though we were able to make it off the freeway with hazards on. However shortly after exiting the vehicle further slowed and eventually died on the side of the road as did the hazard signals.
The vehicle is less than 1 years old. Had 91% charge left. Turned in the car as usual. Turned in heated seats and heated steering wheel as the outside temp was 34 degrees. A pop noise occurred and my entire dashboard flashed like a Christmas tree saying electrical system failure. Pull over safety. The cars speed was reduced to 20 mph. This was extremely scary as this happened on a main road where the speed limit was 55. The ICCU failed according to the dealer. This has been a common issue among Ioniq5 cars and the manufacturer has failed to fixed this issue. This car presents a high failure rate of the ICCU computer that controls the entire car. Once this chip fails, the car can not be driven and it must be towed back to the dealership. This is not a one off. Hyundai also quietly remove the remote start feature to activate the heated seats. They must know that turning on the heated seats might trigger an overload causing possible risk of iccu failure.
The Integrated Charging Control Unit (ICCU) failed while I was driving to work. I was on the highway in the middle of a blizzard and the "Check Electric Vehicle Systems" warning popped up on my dash. It then when into a turtle mode and my car would no longer go above 15 - 20 mph. I had to exit the freeway very abruptly because my speed was dropping quickly. It was already extremely dangerous driving that day, this just added on top of it. It is available for inspection, it's been sitting at my dealership since March 6th because the ICCU is back ordered and there is no ETA when one will become available. The dealership has inspected and confirmed it is a faulty ICCU. There were no other problems with the car until the warning appeared on the dash. The ICCU has had 3 manufacturer recalls for the ICCU previously. Which I have gone in to the dealership for.
ICCU failed while driving. Causing the car to dangerously decelerate with little to no warning. The car then bricked itself on the side of the road. Diagnoses is a failed ICCU. This failure was insanely dangerous as the car lost all power and would not accelerate.

The forward collision system will intermittently erroneously detect objects in front of the vehicle while stopped or in motion. While driving on the freeway, this will cause the car to engage the emergency braking system endangering those in and around the car. While stop to the stoplight, this causes the front detection alarm to go off. The dealership has reproduced the error and tried software updates and replacing sensors, but the problem persists.

While backing into my driveway if a car passes in front on the street my car will not continue backing up. This also happens in parking lots. While backing out of my driveway onto the street and staying in the lane closest to the driveway, traffic in the far lane will cause the car to stop moving even though the street is more than wide enough to accommodate both cars without crossing the double yellow lines. As I live on a busy street this can cause an accident. In both cases turning off the parkin sensors with the dashboard button has no effect.

The tubing that is used to connect the windshield washer reservoir to the nozzles that deliver the washer fluid to the windshield is prone to rodent activity. This tubing has been punctured by rodents twice now - with one intervening tube replacement. I have to replace the tubing again today. It has been less than two weeks since I last replaced the tubing. The replacement tubing was purchased from a Hyundai dealership. It appears that this will be an ongoing issue that will impact the operational safety of the vehicle.
I purchased a 2024 Ionic 5 on January 29th on a day without rain/snow. The first time it rained I found out that there was no rear wiper. I assumed there to be one as its a SUV with a slanted back window, not straight up and down. When it rains or snows the water/snow just sits on the back window, making it impossible to see out the back window. I know every Ionic 5 is like this. On researching the 2025's now have them due to customer feedback. I don't believe this is a convenience issue, but a safety one not being able to see out the back window.
It is impossible to see through the back window when it rains. It has no wiper--and unlike other cars, it is not aerodynamic and does not push rain off the back windshield. When it rains, you cannot see anything. Due to the location of the backup camera, it also becomes wet and you cannot see anything when doing in reverse through the window or backup camera when it's raining.
Overnight, the windshield spontaneously developed a huge crack going from the A-pillar to halfway across the windshield. The car was parked at the time.
I took my 2024 limited Ioniq 5 to the dealership [XXX] to have a TSB looked at and because on [XXX], I took out the cabin air filter out of the car, as I have been noticing a smell of chemical in the cabin of the car. I noticed that the filter was covered in blue windshield wiper fluid and smelled of the same chemical smell as what my wife and I had been smelling and what I believe has been giving us headaches on long trips when driving to San Antonio, Texas to visit our grandson over the last two months. The Technicians at the Hyundai Dealership where I took my car had conducted an inspection and found the filter was covered in windshield fluid and noted that it is most likely caused by a defect in manufacturing or design within the vents where the fluid drains. Which also means that rainwater or water from washing the car could also be going into the cabin air filter housing. The dealership informed me that they have taken pictures and will forward to Hyundai as part of the process however they believe that this could result in a recall, as they noted that there is not a fix, they can provide to stop the fluid from going into the housing and that it is a health risk among other things. They noted that they believe this to be on the new 2024 models as they have not had the issue on the 2022-2023 models. I am concerned that drivers such as myself are being exposed to the effects of inhaling these fluids which include Headaches, blurred vision, vomiting and other unpleasant effects related to inhaling the vapors from this fluid. I only have this one car and cannot simply avoid driving it in weather where I would have to use my wipers and fluid. I would like to have this defect corrected ASAP to avoid any long-term health effects. The dealership was unable to provide a loaner vehicle and I have to wait until Hyundai is able to work a solution or more people complain about it.

Vehicle steering or at least power steering failed catastrophically. Started with some electronic sounds at extremes of turning radius but subsequently failed completely and rendered car undriveable. Hyundai repair center attributed this to "excessive dirt and dust" or some external force, but was unable to substantiate or demonstrate any damage to parts they say need replacing. Ultimately this remains undiagnosed with regards to cause but dealer clearly identifies need to replace P/S motor and rack and pinion assembly. Insurance inspection documents no sign of external involvement in the failure. No warning lights/messages. Problem is repeatable. While failure would have been a safety risk at higher speed, it went from "noise at edge of turning radius" to "cannot steer the car" at a point in time where the car was moving at low speeds.
This is the second time the ICCU failed. The car is waiting for a full EV battery replacement. The first time the failure happened on 12/11/25, at 9,165 miles, the alert happened just before the car came to a full stop as we were driving along the road near our house, it was very difficult to steer, we were sort of stopped in the road and had to get it towed. The second time the alert came on 4/16/26 and we were able to get it to the dealer.
The vehicle was returned to me after a manufacturer-authorized high-voltage battery replacement that was completed on December 10, 2025. Immediately after pickup, the vehicle began exhibiting safety-related issues. I experienced abnormal and hard steering operation, repeated low coolant warnings, and battery management system (BMS) and electrical warning messages. These warning messages appeared immediately after the repair and before the vehicle was driven by me. I returned the vehicle to the dealership multiple times for the same issues. During the final visit, the dealership retained the vehicle for approximately 12 days. After this inspection period, I was informed that the vehicle had underbody damage affecting the coolant system and high-voltage battery and that the damage was likely caused by road debris. The issues began immediately after the battery replacement and involved safety-related systems including steering, coolant, and the high-voltage battery. The vehicle was returned with unresolved warning messages related to these systems. I am concerned that the vehicle was released after a major battery repair in an unsafe condition and that the affected systems may not have been properly inspected or repaired prior to release.

As we drove toward the highway to begin our journey home in our 2024 RWD Ioniq 5 with our entire family and luggage in the vehicle, we received a "Check Electric Vehicle System" warning and immediately pulled over and called Hyundai Roadside Assistance. They initially were going to send someone to jump the car, assuming it was an ICE, but once we said it was an EV, they said they didn't have the equipment to jump an EV. We then spoke to Hyundai Customer Care, and we reported that we received the "Check Electric Vehicle System" warning. The HCC rep said that she did not see any issues with the vehicle on her end, so we would be OK to drive it. We specified that we had a 1.5 hour drive home and asked her explicitly if we would be OK to drive this length of time with this warning and make it home? She again said that we would be OK to drive it. After getting off the phone with her, we proceeded onto the highway and within about 2 minutes, received the "Stop Vehicle and Check Power Supply" warning and then, within a few seconds, began to lose power. This was extremely dangerous, as we were going down a hill on a highway frequented by semi trucks in the rain. Fortunately, we were still able to turn on the hazard lights and coast into a nearby hotel parking lot. As we were losing power, we were afraid we would not be able to get out of the car because all the doors were locked and the windows were up due to the rain, so we quickly unlocked two of the doors as soon as we pulled into the parking lot. One of us then had to stay with the car at all times because we couldn't lock or unlock the car. We eventually had the car towed to the Hyundai dealer closest to us who determined that the ICCU and fuse had failed and needed to be replaced, but they could only replace them with new parts of the same design that could potentially fail again; Hyundai does not yet have a fix for the ICCU failure.
On the morning of [XXX] I received an error message on my dashboard (attached) "Stop Vehicle and Check Power Supply". The car had started to lose acceleration power to no more than 30MPH. I contact the service department at my local dealer. They instructed me to bring it in or have it towed. I was about 2 miles from home so I headed back. While in transit the car lost all power in the middle of traffic. It stopped completely ! No emergency flashers, lights, power for the doors, windows, etc. I could not even put into Park. If I lifted my foot off of brake, it started to roll backwards. Luckily I was not on the expressway or at a railroad crossing. Fortunately a local police officer saw my dilemma and directed traffic and pushed my car to the side of the road ([XXX]) After doing research online I found this to be a common issue with Hyundai/Kia EV vehicles. The ICCU fails with no warning leaving drivers stranded.. The unit is on backorder because of so many failures and there is no ETA INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While backing into my driveway if a car passes in front on the street my car will not continue backing up. This also happens in parking lots. While backing out of my driveway onto the street and staying in the lane closest to the driveway, traffic in the far lane will cause the car to stop moving even though the street is more than wide enough to accommodate both cars without crossing the double yellow lines. As I live on a busy street this can cause an accident. In both cases turning off the parkin sensors with the dashboard button has no effect.
When on a highway with lane-keeping assist engaged, the car sometimes steers into the left-hand lane. It seems to happen most often when the road bends to the right. The car straddles the lane divider into the fast lane to the left. This occurs in otherwise perfect conditions: sunny, dry days on roads with clear white stripes demarking the lanes. I must fight with it to get it back in the proper lane. This is very dangerous. I'm convinced it will cause a high-speed crash. Another driver I spoke with said she had seen the same problem and wouldn't use the lane guidance because of it. I'm extremely cautious when I use it now. The problem has happened multiple times.

The collision detection and early warning system behaves in a manner that deceives the driver into believing a collision is imminent every time the car begins to reverse out of a normal parking spot you find in a parking lot. Despite the car knowing the vehicle is in the reverse gear the driver will begin receiving audible, visible, and haptic feedback alering the driver of an imminent collision. After pausing the procedure of vacating a parking spot to determine where the car has detected a collision the HUD indicates that it is the sensors in the front of the car that were detecting a possible collision despite the car being in reverse and moving away from the objects the front sensors detected. Furthermore, these alerts don't begin until you begin reversing which makes the situation very dangerous for all parties as the driver is now having to freeze and reassess again before proceeding. But the most dangerous problem about this scenario I am describing is that I as a driver have now gotten used to these "false" positives and as a result I assume any alerts I here while backing out are just the front sensors being noisy when it could be someones child behind the car I am driving. Fix this! How was your safety or the safety of others put at risk? High risk. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. Working as intended from all research I have found online from other Ioniq 5 owners.

TIRE SIZE 235 / 55 R 19. Vehicle is a 2024 IONIQ 5. Issue began at/around 10k miles of use. Sound dampening foam inside of the tires comes loose and bunches up in the tire, creating varying degrees of car shaking and vibration. At its worst, the steering wheel and tires violently shake, especially between 50 - 75 mph. On the highway this causes a very dangerous situation of the driver fighting the wheel to remain safely within their lane. This can happen with no warning (or very little) as the vibration may be subtle at lower speeds on local roads, only to become unexpectedly extreme and violent while speeding-up to join highway traffic. Local Hyundai dealership inspected and tried rotating and balancing which did not fix the problem. Finally they removed the tires and inspected the foam which fixed the issue on one single tire. Cost was passed to the consumer, who is not at fault. And with only one tire addressed, the potential remains for each tire to experience the same failure without warning as time goes by. This is a very dangerous issue, well known as evidenced by complaints since 2023 online, and is going to cause accidents. It is unacceptable that drivers have risk their safety and that of other drivers if they lose control of the car due to the inability to control the steering wheel. Then have to pay to fix this issue or pay for new tires after only 10-12k miles.

Real owner reports filed with NHTSA (showing 1 of 1):
While turning a corner at low speed to enter a parking lot, the right rear tire lifted up onto the curb. The car stopped at a parking spot 100ft later. A low tire pressure alarm indicated an issue, upon inspection there was an audible hiss and the right rear of the car was lower than the other sides. As there was no spare, roadside assistance was contacted and towed the car to the nearest dealership for estimate. The dealer found the right rear wheel was bent on the inside and the wheel, tire, pressure sensor would need to be replaced. The cost was $1,612.68 and was covered by insurance. The point of failure on the wheel was not at the site of impact with the curb. The right rear wheel/tire would touch the curb on the outside first. There was no observable damage to the outside wheel. The inside wheel would have been exposed to much less force, most due to the mass of the car lifted on that corner. If not related to the specific wheel, but to the design, repeat incidents can happen when hitting potholes or other road obstacles/debris and result in a quick deflation while at speed. There was no visible damage, cracks, impressions on the tire. Only the rim was visibly damaged by this incident. The car had been purchased 4 days prior.

Official U.S. government 5-star crash-test results.
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.
