NHTSA investigations into the 2024 Chevrolet Traverse

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

On July 31st, while backing up on a clear road in rain the brakes locked suddenly. The brakes applied & a message saying Emergency Parking brake engaged. Must be manually released. This happened twice in a 30 second period before there was enough room for me to pull forward out of the spot. I called the dealership on August 1st to see if this was a known issue and they said no. Brought the car in on August 2nd. They scanned for errors & found a message Lost Communication with Parking Assist Control Module with 9 other error message. They said this was not a known problem and to them it appeared to fix itself but would let me know if there was any way to fix. Car has just been in for regular multi point inspection on July 24th. On August 20th went to get in the car but none of the key fobs would open it. Called two dealerships but neither could come up with answer. Chevy Roadside was called & came to get into the car and ended up jumping it. At that time the battery was tested and it appeared fine. It was recommended to run it for a half hour. I ended up driving it for an hour with no extras on. On August 25th the next day I went to drive it the battery of this 1 year old car was dead. Called the two dealerships to see what could be done & was told to bring it in. Called Chevy Roadside Assistance who dispatched someone to open the car and jump the battery. This person found the battery was not holding a charge & said nothing when I said I was driving it to the dealership. Got 3 houses away & a message that the Brakes have failed. Press hard to brake popped up. In addition the steering locked up. I missed hitting a lady with a kid in a stroller by 6 ft but managed to get it to the curve & with 3 pushes into park. It was towed to the dealership. When it arrived at the dealership the brakes locked up so it would not back up off the flatbed. It had to be forced off. Dealer blames poor battery but can't explain July 31st or why battery readouts say okay.

SERVICE BRAKES

There was a sent out that GM dealers needed to at no cost provide the software update to several vehicles due to a software issue that puts out an emergency warning that the brakes are wearing and are critically low when in fact they are not. Without the new software vehicle owners cannot manually reset the notification even after changing their brakes. I recently took my truck to David Chevrolet who advised me I needed to pay $193 for this software update which goes against the notice from GM and the DOT. I’m now driving without my brake monitoring system on because the dealership will not update my software. I’m filing a complaint because I should not need my brakes changed again by the dealership as I have already replaced perfectly good brakes because I didn’t know there was a software problem. My vehicle is well under the 36k mile and is only two years old.

ELECTRICAL SYSTEM

I am reporting a serious safety incident involving my 2024 Chevrolet Traverse RS AWD, with approximately 34,378 miles. On or about [XXX], while the vehicle was being driven near Sarasota Florida at approximately 25 mph, it suddenly lost propulsion and all electrical power. The instrument panel, displays and vehicle electrical systems went completely dark. The vehicle was completely dead and would not restart. Police subsequently jump-started it, but the vehicle’s systems did not initially operate normally. This vehicle previously experienced another complete electrical-power failure while parked overnight, and the dealership has a record of that incident. Following the in-motion shutdown, the dealership performed a complete software flash using USB and stated that a software problem may have caused a parasitic battery draw. I understand how a parasitic draw could discharge the battery while the vehicle is parked. However, I have not received an adequate explanation of why the vehicle lost all electrical power while the engine was running and the charging system should have been supplying power. I am requesting that General Motors open a formal product-safety case, review the dealership’s diagnostic and programming records, determine the complete cause of the in-motion shutdown, and provide written confirmation of the tests and repairs performed. Please provide me with the GM case number and escalate the matter for appropriate technical or field review.

SERVICE BRAKES

I am writing to express my disappointment with the quality and reliability of my vehicle. Since purchasing it, I have had to return it to the dealership on five separate occasions due to ongoing defects and mechanical issues. Shortly after purchasing the vehicle, the Super Cruise system failed to function properly and required service. At approximately 15,000 miles, I was informed that the brake pads were already excessively worn and needed replacement, which I believe is premature for a vehicle with such low mileage. Most recently, the check engine light illuminated, requiring another visit to the dealership for diagnosis and repair. These repeated issues have caused significant inconvenience, wasted time, and disrupted my daily life. I purchased this vehicle expecting it to be safe, dependable, and of high quality. Instead, I have experienced recurring problems that have seriously affected my confidence in the vehicle. Given the number of repair visits and the ongoing defects, I respectfully request that General Motors review my case and provide an appropriate resolution. I would appreciate a prompt response and a fair remedy to address these continuing issues. Thank you for your time and attention. I look forward to hearing from you soon.

SERVICE BRAKES

There is a known issue with the software / brake monitoring system with the 2024 Chevy traverse. The brake pad sensor is faulty and the vehicles warning system tells you that your brake pads are critically low when in reality they are not. Even after you change the brakes and put a new sensor you cannot clear the notification. The only way to reset this is to either take it to the dealership for them to change your brakes or pay $200 to obtain the fix for the software. Now this is bricks maintenance meaning as the consumer you should be able to maintain your vehicle on your own but GM has made this impossible which will force the consumer to turn off their brake monitoring system to remove the faulty warning. This is a safety risk for the consumer and the other people on the roads. This update should be done free of charge but they refuse to do it.

SERVICE BRAKES

VEHICLE: 2024/2025 Chevrolet Traverse RS COMPONENT: Electronic eBoost Brake Master Cylinder Assembly DESCRIPTION: Within a few months of purchasing the vehicle, the brake pedal began exhibiting excessive free play (long pedal travel) and significantly delayed stopping behavior, particularly dangerous at highway speeds. The vehicle requires substantially more stopping distance than normal, creating an imminent rear-end collision risk. This defect has been brought to the dealership's attention twice already. The vehicle was just serviced and returned for this same issue. After each service visit, the brakes temporarily function normally for only 500 to 1,000 miles before the dangerous delayed braking behavior returns. Previous dealer repairs included bleeding the brake lines and updating the Electronic Brake Control Module (EBCM) software — both failed to permanently resolve the issue. The root cause appears to be an internal bypass leak within the electronic eBoost brake master cylinder assembly, where defective internal rubber cartridge seals allow pressurized fluid to slip past them over time, progressively degrading braking performance until the next service intervention. This is a REPEAT safety failure. The vehicle has been serviced for this identical brake defect TWICE, and the condition returns each time within 500–1,000 miles of the repair. This issue is documented under GM Service Update N242482170 and TSB 25-NA-029, and is the subject of active class-action litigation affecting 2024–2025 GM SUVs. The driver and all vehicle occupants are placed at serious risk of injury or death due to the inability to stop the vehicle within a safe distance during normal highway driving conditions.

Vehicle: 2024 Chevrolet Traverse Z71 Mileage at first incident: 25,821 My 2024 Chevrolet Traverse Z71 experienced multiple safety‑critical electrical and ADAS failures. The vehicle had a Reduced Acceleration / limp‑mode event, accompanied by a strong antifreeze odor inside and outside the vehicle. Dealer diagnostics on 06/29/2026 and 07/16/2026 confirmed several trouble codes affecting the engine, braking system, and collision‑avoidance systems. The following diagnostic trouble codes were recorded: P3705 – Engine Coolant Pump Control Circuit Low (engine cooling fault) C0609 – Park Brake Actuator / Switch Signal Fault (brake system logic fault)-Active 6.29.26 10:12:43AM U160A – Lost Communication With Serial Data Gateway Module (CAN‑bus gateway failure)-Active 6.29.26 10:12:43AM U197A – Lost Communication With Front Radar Sensor Module (forward collision warning / AEB disabled)-Active 6.29.26 10:12:43AM These faults caused loss of radar‑based safety features, including Forward Collision Warning, Automatic Emergency Braking, and Adaptive Cruise Control. The vehicle displayed warnings and temporarily disabled ADAS functions. The Reduced Acceleration event created a hazardous situation in traffic. The dealer attributed the incident to “low coolant,” but the diagnostic codes clearly show electrical and communication failures across multiple safety‑critical modules. The antifreeze odor continues, suggesting a possible coolant leak or unresolved cooling system issue. The vehicle has been inspected by GM technicians, and the codes were documented on both visits but they say car is fine. The safety systems affected include brakes, engine cooling, electrical CAN‑bus communication, and collision‑avoidance radar modules. I am requesting NHTSA to record this complaint and evaluate whether these failures represent a broader safety defect in the 2024 Chevrolet Traverse Z71.

My breaks have been squealing on my 2024 Traverse since about 6 months after my purchase in 2024. I have taken it to the dealership on multiple occasions and they stated that GM knows of the issue but there is no fix. The system states my front breaks are low. I recently took my Traverse to a break repair/replacement shop and they stated my breaks are not low and they look great and numerous people have brought their Traverse in with the same squealing complaint. With the amount of complaints why hasn't GM done anything about it?

SERVICE BRAKES

I took my vehicle in several times for issues regarding the brakes. I was told for months nothing was wrong. The brake percentage was rapidly declining on the display and they just kept saying it would fix itself in an update. Finally the service brake alert came on prompting me to take it to the dealership again for the brakes. I was told my front brakes were completely gone and needed new pads and rotors and my back brake lines were severed and pouring brake fluid everywhere. I was told I was lucky I brought it when I did because I could have gone to stop and just not been able to. It was concerning because there was no warning or indication there was anything wrong and I kept being told everything was fine

Back in December 2025 took car in because there was a coolant leak until the car started. Alerting me that it was overheating in the middle of the freeway. I had to find a place to pull over while the car was alerting. With urgent urgent urgent alert to pull over. Took it into dealership and it Turns out it had a coolant hose leak . I took the car in for an oil change TODAY and turns out has a host leak again. The dealer did the inspection and I don’t have the part available to fix it. And this is a brand new car giving me issues. I travel far on weekend so this would be hazzard. The dealer said the water tank low because of the leak. It’s also the rear backseat window would not go Thank you It’s leaking, and that’s a safety issue. Because if there’s Down emergency, we can roll the window down. We also had an issue with the break pad alert system alert me. There was no brakes. It turned out to be in update issue and again I was going to travel on vacations. Those are other issues. I’ve had with the car but the maintenance issue today is at the clothes again is leaking and is a safety hazard because if I’m driving and the car and it overheats.

On the car seat there are two indicators to tell you if the seat is locked in place because it is a rotating car seat. Both indicators never fully go in the “green” meaning the seat is fully locked into place. The car seat is less than two years old and both indicators are malfunctioning, they aren’t going fully in the green. I reached out to the company with pictures and videos and they have done nothing to help. They said from the video it looks like the car seat is functioning properly and they will not fix or replace it.

STEERING

The 2024 Chevy Traverse has super cruise. It is basically an auto drive feature. It has sensors in the top part of the steering wheel. This plastic area is known for cracking and the dealership said there is nothing they can do. This is absurd. They know there is an issue with the wheels cracking and they are not fixing them under the warranty.

SERVICE BRAKES

At purchase, I noticed that the brakes felt spongy and were screeching when the salesmen pulled up. The salesmen stated that new brakes always screech due to burned plastic. Weeks later, I scheduled a servicing appointment with Chevy Crews in North Charleston, due to brake screeching, the repairmen told me again that the brakes had condensation on them, so he dusted them off and the screeching would stop in 3 weeks. 3 weeks later I returned again, the salesmen told me that GMC made the vehicles with faulty brakes. My vehicle was seen over 4 times for screeching brakes, thousands of consumers have complained about the same issue, and GMC has failed to act.
