Official recall campaigns. Tap one to see the danger and the fix.
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.
NHTSA Campaign 20V603000
What's wrong: General Motors LLC (GM) is recalling certain 2018 Cadillac Escalade, Chevrolet Silverado 1500 and Tahoe, GMC Sierra 1500 and Yukon vehicles equipped with either a 5.3L or 6.2L V8 engine. The output of the mechanical vacuum pump can decrease over time, decreasing the amount of vacuum/power brake assist.
The danger: A decrease in brake assist can increase the brake pedal effort and distance required to stop the vehicle, increasing the risk of a crash.
The fix: GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began November 11, 2020. Owners may contact GM customer service at 1-866-522-9559, Cadillac customer service at 1-800-458-8006 or Chevrolet customer service at 1-800-630-2438. GM's number for this recall is N202300860.
NHTSA Campaign 19V645000
What's wrong: General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.
The danger: As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.
The fix: GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began October 8, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192268490.
NHTSA Campaign 19V761000
What's wrong: General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
The danger: Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.
The fix: GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.

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.

I had an accident in this vehicle where the airbags deployed upon impact (as they were designed). However, once airbags deployed, my vehicle was filled with smoke (from the airbags) and all of my windows were covered and I couldn't see out. Panic set in as I tried to get out of the vehicle and my door would not open. After several moments I thought about the door locks, they were engaged of course. Once I realized and hit unlock, the door opened. This isn't an issue as far as parts being a defect or anything like that, but today I heard of a Texas DPS Trooper being in an accident in his Tahoe. His took a front impact as well, and the person trying to help him couldn't get him out of the vehicle. It made me wonder if his locks were engaged too, and him being more severely injured may not have thought about the door locks. This could be a potential safety risk, especially if the vehicle is on fire. What if vehicle manufacturers were able to install a safety mechanism that would automatically release the door locks if an impact was detected, or air bags were deployed? Just merely a suggestion as none of the parts on my car failed, they all did their job, but not being able to get out of your car is terrifying. I'm not sure if I am in the right place to pass on this suggestion, so if not, please advise where I might leave one. Thank you.
WHEN IT RAINS REALLY HARD, THE ROOF IN THE B PILLAR LEAKS ABOVE THE SEAT BELT AREA INTO THE HEADLINER. MY HUSBAND WHO IS AN AUTOBODY TECHNICIAN HAS MADE SURE MY SUNROOF LINES ARE CLEAR AND THE WINDSHIELD MOLDINGS AND SEALS ARE GOOD. HE HAD ANOTHER ONE AT HIS PLACE OF EMPLOYMENT WITH THE SAME ISSUE AND IT WAS THE ROOF WELDS, WHICH ARE DONE BY THE MANUFACTURER. I AM HEARING MORE AND MORE TAHOE OWNERS WITH THIS SAME PROBLEM. AS MUCH AS THESE VEHICLES COSTS US, THIS SHOULD NOT BE HAPPENING. THIS CAUSES MOLD IN THE ROOF AND RUSTING. THIS HAS TO BE LOOKED INTO BECAUSE THIS IS AN EXPENSIVE REPAIR IF I NEED TO HAVE THIS PROBLEM FIXED AND COULD ALSO CAUSE HEALTH ISSUES IF NOT ADDRESSED WITH THE MOLD.
Unexpected acceleration
The rear AC evaporator located behind the paneling in the rear of the vehicle was leaking AC freon r-1234yf. This was diagnosed after a weeks long troubleshooting by my mechanic trying to find the leak in the rear AC lines causing the vehicle to fail the vacuum test. After he showed me the part and where the cracks were, he suggested I report this as a safety issue since the coolant was leaking inside the car and is highly flammable. He also said he has had many other GM vehicles with the same issue and thought a recall should be issued.
The clear coat has completely failed on mainly the hood and roof of the entire vehicle. Each of the sides have lost a good amount of shine too but there hood and roof are a compete different color compared to the rest of the Tahoe. The paint is the pewter/grey so it is extremely noticeable and very much an eyesore.

During a road trip, we came to a stop and upon stepping on gas to proceed on the road and it wouldn't go. The engine revved and "pulled" until we were able to move. We took it to a dealership as well as private mechanic and was told it is an engine problem and running $3k or more to have it fixed. We have small children and consider this a safety hazard. Unfortunately, this is the only vehicle we have to commute.
Was driving approximately 45MPH and the truck just slowly powered down and "Engine Power Reduced" and eventually cut off and wouldn't crank back up. Got it towed to the Chevrolet dealership and was told the engine has to be replaced due to the bottom of the motor and the crankshaft in cylinder one. Was told it would be 17k to repair it.

While driving home, the the FAC, forward automatic crash, indicator light came on, I applied the brakes and watched to my dismay as my vehicle slowed down but would not stop. I applied steady hard pressure until impact with another vehicle in front of me. The FAB, forward automatic braking system never kicked in. I will contact the dealer concerning the above issue.
OVER THE LAST 6 MONTHS THE BRAKE PEDAL IS HARD TO PUSH AFTER THE TRUCK SITS OVER NIGHT. THE VACUUM BLEEDS OUT INDICATING A VACUUM LEAK IN THE SYSTEM. GM AND THE DEALER SAID THIS MODEL AND YEAR NOT COVERED UNDER CURRENT RECALL.
The contact owns a 2018 Chevrolet Tahoe. The contact stated while driving at an undisclosed speed, the brake pedal was depressed with the brake warning light illuminated. The vehicle was able to restart; however, the failure recurred. The vehicle was taken to the dealer where it was diagnosed that the vacuum pump had failed and needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 92,104.
Brakes failed pedal went to the floor when getting off the interstate. Kept pressing pedal and came back but vehicle pulls to the left hard when Brake pedal is also very hard to press. Very unsafe afraid to drive the vehicle. Dealer has recalls for same model vehicle show under my vin . Vehicle is available for inspection at anytime.
My vehicle started announcing service trailer brake system when i purchased my vehicle about 5k miles in i took it to the dealer they couldn't find anything wrong now that message started to get worse not only is it a safety concern due to the annoying beeping. Sound on the dashboard indicating something is wrong. It makes me take my eyes off the road it Constantly distracts me every time it goes off. Also, feel every time that message appears. My truck slows down. As well, a safety concern when pulling a trailer. The brake system could fail on the trailer due to trailer brake assist malfunctioning.

The Body Control Module does not work. A new BCM was installed in my car in April 2025. Since then I am having multiple issues, but the safety related issue is with the trailer braking system. It is available for inspection upon request. The dealership is unwilling to try another BCM without it costing me $600 for labor. If I am unable to use my brakes, then I put myself and others on the road at risk. The problem started with a Tire Monitor System. I was told I needed a BCM to fix the problem so the car would not throw codes. Now, I am being told the problems with the brakes are not comiing from the BCM. THERE WAS NOTHING WRONG WITH MY car until I took it to this dealership for a new key faub and a tire pressure monitor error. The Body Control Module in a 2018 Chevy Tahoe Premier does play a role in controlling the sunroof. More specifically, the sunroof system is supplied power through a fuse located in the driver-side fuse box which is connected to the BCM. The sunroof switches communicate with the BCM via a serial data circuit, and the BCM then commands the sunroof to open or close. Therefore, the BCM acts a central hub in the electrical system of the vehicle and communicates with the sunroof control module to operate it. I learned this from two other dealerships. One dealership in West Virginia and another dealership in Texas told me this information about the BCM controlling the sunroof and many other electrical parts of the 2018 Chevy Tahoe Premier. To make it simple, the BCM was replaced. The vehicle is now having serious issues. I consider an unintended activation of the braking on the wheel which causes the vehicle to pull to one side puts me at risk of a crash. Is this yet another failed sensor or part due to the negligence of the service department at Smith Buick when replacing the BCM and programming a key faub?

I was sold a vehicle from a dealer in Arizona that online says they only sell to government or law enforcement
Purchased brand new Chevy 2018 Tahoe in April 2019. Overall good car never had any issues until 02/08/23 as I was driving a got a service alert "Trailer Brake System", It was so random since we have not hauled anything for that to even become a problem. The next day 2/09/23 the car was not drivable it wouldn't turn on it kept giving me the same alert "Trailer Brake System". I called the dealership and they said it's a defect and have to take the Tahoe in for service since only they can find the defected harness and now I have to pay out of pocket for something that I did nothing wrong, something that is manufacture defect and completely unsafe to drive.
Trailer brake system warning, I can’t drive, because it buzz me off! Never used trailer.

The contact owns a 2018 Chevrolet Tahoe. The contact stated that after parking the vehicle in a parking lot and returning to start the vehicle, the “Power Steering Assist Fault” message was displayed, and the vehicle was difficult to turn to the right or the left. The contact left the vehicle in the parking lot and after returning to the vehicle later and starting the vehicle, the vehicle had regained power steering assist functionality. The vehicle was taken to an independent mechanic who diagnosed the vehicle and determined that the 12-Volt battery needed to be replaced. The contact was advised by the mechanic that due to the weak battery, the power steering assist failed to operate as designed. The vehicle was repaired. The contact stated that several weeks later the power steering assist failure recurred. The contact stated that the "Power Steering Assist Fault" message was displayed. The vehicle was taken to another independent mechanic. The vehicle had not been diagnosed or repaired. The contact researched online and related the failure to NHTSA Campaign Number: 21V455000 (Steering); however, the VIN was not included. The manufacturer was not informed of the failure. The failure mileage was approximately 84,000.
First occasion the car drove fine with no indication of an issue. Then once the car was turned off then on, the dash showed no lights or gauges and indicated that the steering assist is not working and the wheel was impossible to turn (almost like a limp mode but not driveable). Disconnected the battery to try and clear the issue and car drove home fine. Was told it could be a bad battery so replaced the battery and it worked fine for about a month. Then again with no indication did it again and this time it cleared itself after about 30 minutes. Dealer said there was a short in the negative battery ground cable and an open circuit in the rack and pinion mechanism but that the rack and pinion part was not available and they weren’t sure when it would be (probably due to excessive failures). Replaced the negative battery ground part and everything was fine for about 3 months until today when the car did the same thing again. We will have to keep looking for the unavailable part or I will basically have a $30k paper weight. Very concerned at the possibility that the steering will go out while I am driving as others have mentioned in previous posts. Seems as though something tragic will have to happen before they issue a recall of a part that appears to be a common failure.
Power steering went out with kids in the car when vehicle only had 76000 miles. There was a special coverage for 2018 models that my vin was not a part of. Had it been this wouldn't have happened to my family. I was without a vehicle for over 2 weeks since dealership had to reach out to GM to find the part. Apparently, this is big issue for other models and years which explains the part shortage. A few months prior there was a service power steering on my dash, and I couldn't turn my steering wheel. Took it to dealership and they brushed it off as computer issue. Again, I feel if my vehicle was part of the special coverage, I wouldn't have experienced this issue or had to pay over $2000 to repair it.
My wife was driving everything was working fine until a message came on the dash "steering stopped Drive with care" she was mid way in a turn to get on highway when this happened if I wasn't in vehicle to grab the wheel my wife would have ended up in a wall or worst case in the canal next to 95 with my 4 year old in the car. The vehicle is currently at a chevorlet dealer in Greenacres Florida and they say the electric steering gear has stopped working.. this seams like a very unsafe system as when it stops the steering wheel is very stiff more than a old car with no power steering. I think this needs to be investigated yesterday as someone could die from this if it hasn't happened already. As of right now I no longer feel that this is a safe vehicle for my wife to be driving
The contact owns a 2018 Chevrolet Tahoe. The contact stated that while his wife was driving approximately 35-40 MPH, the power steering assist failed. The failure occurred on several occasions, which nearly caused a collision. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 120,000. The VIN was unavailable.

I can smell gas inside my cabin and also when parked in garage. Mechanic said my fuel injector seals are leaking and this is a known issue . The safety bulletin 18-NA-137 November 2019. This is a SAFETY ISSUE and needs to be addressed for the safety of myself and others. Please issue recall immediately so I can get fixed.
9-19-23 Vehicle stalled and started sputtering when turned on.
12-11-23 Vehicle was not accelerating when pressing gas pedal then began violently shaking and shut off in middle of roadway.
7-21-23 Unit stalled 3 times today. The last time was while driving. Check engine light on. 1-29-24 Today I was responding to an emergency backup for an officer that was fighting two subjects. The subjects were fleeing from a stolen vehicle and it was dispatched that these subjects were armed. I never made it to this call because my vehicle #10688 would not accelerate past 23mph and then shut off leaving me stranded in the roadway. While waiting for a tow truck I was able to get the vehicle started again and was able to drive at only 36mph to try to get to the scene and assist the officer. I ultimately was able to make it to the police station. I wrote up the vehicle and left the keys in the training building.
The repeated failure of the fuel pumps, despite replacement three times, poses a significant safety concern as the vehicle may not start immediately, potentially leading to issues while on the road. This delay in starting could result in the vehicle not running properly, potentially shutting off unexpectedly, which poses a danger to the safety of the driver and others on the road. Additionally, the uncertainty surrounding the effects of using E85 fuel, despite the vehicle being sold as flex fuel, raises concerns about the long-term viability of the motor and overall vehicle performance. It's imperative to address this issue promptly to ensure the safety of all road users and preserve the longevity of the vehicle's components.

The contact owns a 2018 Chevrolet Tahoe. The contact stated that in 2024 the front windshield was damaged, and the windshield was replaced. The Insurance Company was notified and requested that an aftermarket windshield be placed on the vehicle. In May of 2025 the contact noticed that the Chevrolet Assist Camera behind the rearview mirror had failed. The vehicle was taken to the dealer, who determined that since the windshield was not an OEM windshield replacement, the part caused the camera to fail. The camera was unable to be calibrated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 82,000.
Caliper became stuck which produced smoke coming from tire. Had the caliper replaced. Then months later my forward collision system activated because a car in front of me stopped abruptly. After the car automatically braked to slow my car down, the brake never released and became stuck and the ABS light came on. Replace the abs sensor and two days later the brake engaged on its own while doing 60 mph on the highway. Now whenever the hill assist, collision warning, or anything else is activated, the brake engages and gets stuck. In addition, at times on the highway my brake will engage on its own.
While driving home, the the FAC, forward automatic crash, indicator light came on, I applied the brakes and watched to my dismay as my vehicle slowed down but would not stop. I applied steady hard pressure until impact with another vehicle in front of me. The FAB, forward automatic braking system never kicked in. I will contact the dealer concerning the above issue.
My vehicle recently has had 2 issues that I have taken in to the Service Shop for 3 times and the problem has not been fixed. My most concerning issue is my brakes. My brakes are doing the exact problem indicated in this article: https://www.consumerreports.org/car-recalls-defects/gm-recalls-suvs-and-pickups-for-braking-issue/ When the brakes malfunction, I feel a vibrating brake pedal, feels like my vehicle is not going to stop on time, I hear a ticking noise from the engine and my Brake Assist Service light comes on. The issue continues until I can pull over and restart the vehicle. It is a very uneasy feeling having to drive a vehicle that you do not feel safe in. I called 800 Chevrolet's Customer Service number provided in the article and they are unaware of the recall mentioned in this article. I do not know where to go from here. I just want my vehicle fixed and to feel safe. My 2nd issue is regarding my Adaptive Cruise Control. I've had it in the shop 3 times for this also and they did replace a part but that did not fix this issue. I will be driving down the highway or interstate and out of the blue my alarm starts dinging, the seat vibrates, the cruise control gets kicked off and I get an alert on my dash stating that the Adaptive Cruise Control was disabled. Each time it has happened to me there is nothing around but it immediately starts reducing my speed. If someone were behind me it could cause a crash because of the unexpected speed limit reduction. When you go in to look at recalls on 2018 Chevrolet Tahoes it shoes that there is 3 of them that have been issued, yet my VIN is not included in any of them? What can I do from here? I've called Chevrolet's 800 # and they created a "High Urgency Case" but I have not heard back. Attached are my copies of service records and vehicle summary showing there has never been recalls on my VIN #.

I HAVE HAD MY SUNROOF CHECKED, MY WINDSHIELD CHECKED AND DRAIN TUBES CHECKED. THERE IS NEVER ANY WATER OR WETNESS ON THE FLOOR, ITS ONLY THE HEADLINER. THIS HAS BEEN AN ON-GOING ISSUE. I HAVE BEEN INVESTIGATING IF THERE ARE OTHER TAHOES DOING THE SAME AND YES THERE ARE AND 1 HAD WENT TO A BODY SHOP AND THEY FOUND OUT THAT THE MANUFACTURER WELDS WERE NOT WELDED CORRECTLY, WHICH CAUSES WATER TO GET INTO THE ROOF. THIS CAN CAUSE MOLD AND EVENTUALLY OTHER ISSUES. IT HAS STAINED MY HEADLINER. SOMETHING NEEDS TO BE DONE ABOUT THIS BECAUSE I CANNOT AFFORD TO HAVE A BODY SHOP FIX THIS KIND OF REPAIR AND I SHOULD NOT HAVE TO FOR AS MUCH MONEY AS I HAVE PAID FOR THIS VEHICLE. I HAVE VERY YOUNG GRANDKIDS THAT RIDE IN THIS VEHICLE AND ONE HAS VERY BAD ALLERGIES AGAINST MOLD. AND IT IS NOT FAIR THAT I EVENTUALLY WILL HAVE TO GET THIS FIXED BECAUSE IT WILL ALSO CAUSE RUST. PLEASE DO SOMETHING ABOUT THIS.

THE BRAKE PEDAL IS TOO CLOSE TO THE DRIVER IN RELATION TO THE GAS PEDAL. THE DISTANCE OF EACH PEDAL CANNOT BE ADJUSTED INDEPENDENTLY. A DRIVER'S FOOT CAN BE TRAPPED IN BETWEEN THE TWO PEDALS BECAUSE OF THE GAP. IN A FATAL SITUATION, IT TAKES LONGER FOR THE RIGHT FOOT TO MOVE FROM THE GAS PEDAL TO THE BRAKE PEDAL SINCE THE RIGHT FOOT CANNOT JUST MOVE LATERALLY TO THE LEFT, BUT IT NEEDS TO GO AROUND.

In addition, mentioned the noises again. No service was completed, service stated it was due to colder temperatures. 25,000- Asked service dept. at dealership to check hard shifting from transmission and poor performance. In addition, mentioned the noises again. Engine cooler lines were replaced. Scanned and verified clutch learn values all normal. Activated TCC and disabled TCC and found normal operation. No service completed. Now, after warranty has expired, service at dealership is telling me my camshaft and lifters need to be replaced, struts are leaking, transmission needs attention and should be flushed, and that I should NOT be driving my vehicle due to safety concerns. Although, I had taken the vehicle in multiple times during warranty period with complaints about these very items, no service was ever completed to correct them. Since then, I have read multiple articles documenting GM issues with L87 6.2L engines and transmissions. I'm filing a formal complaint with GM, as these issues should have been communicated to consumers or fixed through recalls.

LT275 65 R18 123/120 R DOT 1 BE BP AT 21 My daughter has pictures of the tires, all four tires (all bought at the same time) 05/6/23 from Discount Tire, are splitting along the side wall, originating at the tread line, we have talked with Discount tire, there are 40,000 miles approximately on the tires. They have been appropriately rotated and balanced. There have been no repairs of the tires. This is noted to be a defect, not normal wear and tear of the tire, per Discount Tire. They have offered 423.00 credit to purchase new, and have come back with 50% off new tires. Since this is a defect, verse actual wear and tear I do not believe that is appropriate. 75-100% of the replacement value. The tires should reasonably last between 5-6 years. The defect increases the risk of a blow out on any one or several of the tires. Discount Tire in Lubbock has confirmed that there is an issue, but I am not happy with their resolution.

The contact owns a 2018 Chevrolet Tahoe. The contact stated that in 2024 the front windshield was damaged, and the windshield was replaced. The Insurance Company was notified and requested that an aftermarket windshield be placed on the vehicle. In May of 2025 the contact noticed that the Chevrolet Assist Camera behind the rearview mirror had failed. The vehicle was taken to the dealer, who determined that since the windshield was not an OEM windshield replacement, the part caused the camera to fail. The camera was unable to be calibrated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 82,000.

When I started car I got service messages for side detection system, tire monitor system, safety restraint system, front camera system, trailer break system and theft deterrent system. Each one gave option to dismiss. When I would dismiss the messages would come back. When I was driving, all the things on dash, mph, oil, battery etc all stayed on zero. Super dangerous and I could have died!!!!!!. No blinker sound

1- the second row center Seat Belt Receptacle stopped locking so failed, this happened while using the vehicle. 2- the seatbelt receptacle stopped latching while using the car in Seattle, I had to drive with someone in that seat unbuckled because all other seats were being used. 3- the receptacle can not be repaired, needs to be replaced; 4- I have contacted the manufacturer to have them fix this but they will not do it without compensation. 5- no warning. the vehicle is not old and in very good condition. I drive with my family in the car daily but rarely need to use the middle seat. I feel this is a defective latch due to the limited use and age of vehicle. I am concerned that the other seatbelts will also break without warning and Think that GM needs to be aware of a possibility.

Color = how serious (crash/fire involvement) · number = how many (share of all this car's reports). Tap any part to read real owner complaints.
How it compares
Lower than most complaint volume — 101 complaints ranks #1 of 24 popular models from the same year (fewest first · median 609).
6% of its complaints involved a crash or fire, vs 5% typical for its year — this one is fair to compare directly, because it doesn't depend on how many were sold.
Why raw complaint counts can mislead (and how we correct for it)
A best-selling car naturally collects more complaints than a rare one simply because there are more of them on the road — so a raw count alone can make a popular, reliable car look worse than a troubled niche one. That's why we show the rank alongside the crash/fire percentage (which doesn't depend on sales volume) and the same model's other years. Read all three together.
Computed by us from NHTSA complaint records for 24 popular same-year models · snapshot 2026-07-10. This comparison set is a sample, not every car sold.

Crash-Test Safety Ratings
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.
