Owners have filed 323 complaints
about the 2025 Chevrolet Traverse with NHTSA between 2025 and 2026.
The largest single group is the brakes.
Across this model's run it ranks 12 of 18 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 37
Against the median year of the Chevrolet Traverse. 50 means typical for this
model; 100 means roughly double.
Severity — 19
3.7% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 100
85% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
How 2025 compares with every other Chevrolet Traverse
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

When owners complained
A spike years after the car went on sale usually means a part wearing

NHTSA investigations into the 2025 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.

Electronic Brake Module Component Failure
On April 11, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24011 after receiving complaints concerning a loss of brake assist in 2023 MY Cadillac Lyriq vehicles. These complaints allege a hard brake pedal, followed by a “Brake System Failure” message at start up or while driving. GM shared records regarding several internal investigations for loss of brake assist due to alleged spindle fractures in the eBoost system. GM has stated that in the event of a spindle fracture, anti-lock brakes (ABS), stability control, and traction control remain functional until th...

The contact owns a 2025 Chevrolet Traverse. The contact stated that while her husband was driving at 30 MPH on an expressway, occupied with his wife in the vehicle, seated on the front passenger side, attempting to depress the brake pedal, the vehicle failed to respond as intended, causing the front end of the vehicle to crash with the rear end of the vehicle in front. The contact mentioned that the brake pedal felt abnormally hard and excessive force was applied; however failed to bring the vehicle to a stop, causing the crash. The air bags did deploy. The vehicle was towed to a tow yard, the vehicle was then towed to the insurance company. The contact stated she and her husband did not sustain any injuries. No medical attention was required. A police report was filed. The manufacturer was not notified of the failure. The approximate failure mileage was 2,000.

AIR BAGS
I was in t-boned on the passenger side of my vehicle. All side air bags went off but did not deflate. I had to crawl onto my floor to get out of the vehicle. Also when the emergency collision park kicked in it locked my doors so had I been unconscious I would have been locked in the car.

SEAT BELTS
Name: [XXX] •Address: [XXX] •Phone: [XXX] •Email: [XXX] Date of Incident: October 7, 2025 Description of Problem: While driving our 2025 Chevrolet Traverse on October 7, 2025, our son was sitting in the third-row seat and somehow managed to buckle two seatbelts at once—one from the right side and one from the left—crossing them over his chest and neck. Once both belts were latched, they locked in place. When we tried to loosen one side, the opposite side only tightened further, causing him to be choked. We tried multiple ways to release the seatbelts, but the locking mechanism prevented any movement. Several adults tried to help, but no one could free him. We ultimately had to cut one of the seatbelts to safely release him. He was left with visible red marks on his neck, and the incident caused significant fear and distress. The seatbelts were crisscrossed, which explains why attempting to loosen one side made the other side tighten. This appears to be a dangerous design issue, as there was no safe or quick way to release the belts in this situation. We are deeply concerned that this design could pose a serious strangulation hazard to children or other passengers in the future. Attachments: •Photos showing the crisscrossed seatbelts •Photos showing the red marks on the neck after the incident We request that NHTSA review this complaint to determine if this is a vehicle safety defect and take any appropriate action to prevent similar incidents from occurring.

I rear ended a car on 3/12/25, and my automatic emergency braking system light was on at the time. When my car was returned to me, I set the braking system off, so the light was still on, but when I tried to turn the system back on in June, the light came on and told me I needed to get it serviced. As it wasn't a priority to have the automatic emergency braking system, I didn't take my car into the dealership until August 18, when 3 more dashboard indicators came on. The dealership stated they would be waiting on a part for my brakes, but it is on national backorder, with no ETA. It has been in the shop for over 4 weeks (it was dropped of 8/18, but lights came on 8/10).

This started happening about two weeks ago. My check engine light came on and my OBD scanner said a NOX sensor code showed. I told the dealership and I guess they cleared the code and it hasn’t reappeared but the reduced acceleration has maintained. It was [XXX] I had just go of work and needed gas. While traveling to the gas station I got notification that my acceleration was being reduced and it was very noticeable. After arriving and pumping gas, I started the car and got 3 additional messages. The car aside my brake assist and ESC needed service, my ABS system was off, and my forward collision system was off. While driving, I noticed that the brakes were still working but acceleration was still being reduced. This is an everyday use car and I have a 6 children who I don’t feel are safe anymore in the car. Not being able to utilize the brakes and the reduced acceleration is very concerning especially when in traffic. I have a little over 27500 miles on the car. It just came from the dealership to get the telematics module replaced last week because it went out about a month ago. I’ve only had this car a year and it seems like the issues are becoming more common everyday. I will be taking care back to dealership tomorrow.

UNKNOWN OR OTHER
While driving on vacation approximately five hours away from home with my family, I suddenly heard a loud popping sound followed immediately by increased outside wind noise coming from the panoramic moonroof. Based on the sound, I suspected the moonroof glass had shattered. Because my family was in the vehicle, I intentionally did not open the interior sunshade, as I was concerned that broken glass could fall into the cabin and seriously injure my passengers. After safely pulling over, I inspected the roof from the outside and confirmed that the panoramic moonroof glass had completely shattered. During the drive back, the shattered glass panel completely detached from the vehicle and flew off. Fortunately, it landed in the grass and did not strike another vehicle or person, which could have resulted in a serious accident or injuries. Because this occurred over the weekend, I had no immediate access to repairs. To safely transport my family the five-hour drive back home, I had to temporarily cover the opening with a trash bag and tape to protect the vehicle’s interior and reduce exposure to the elements. After returning home, I contacted the dealership, provided photographs of the damage, and explained the circumstances. I was informed that the failure would not be covered under the vehicle’s warranty and that I would be responsible for the repair costs. I am extremely concerned that the moonroof shattered without any apparent impact from road debris or object. Had the interior sunshade been open at the time, pieces of broken glass could have fallen into the passenger compartment, potentially causing serious injuries to my family, including eye injuries or cuts. Additionally, when the glass panel detached from the vehicle, it could have struck another motorist or pedestrian, creating a significant safety hazard. I believe this incident represents a serious safety concern and request that this matter be thoroughly investigated and reconsidered for warranty coverage.

FORWARD COLLISION AVOIDANCE: WARNINGS
Approx 5/19/26 Forward Collision Detection check light randomly came on when driving home and showed notifications showing "Service ESC" "Service Traction Control" then started showing notifications for the collision sensors unavailable and continuously flickering them across the dash. The Fwd collision symbol would come on and off randomly. Finally was able to take it to the dealership on 6/8/26. Dealership found 6 codes and updated the image processing module. The Fwd Collision symbol is back on and off, notifications are flickering across the dash more frequently and now the check engine light is constantly on as of 6/14/26. Car is currently back at the dealership. Pictures and videos were taken of the issue happening to provide extra proof and given to the techs. These sensors failing at any time could cause the vehicle to randomly brake, not brake, and possibly not register a potential accident and avoid it. This vehicle is our daily driver and is the vehicle my son's car seat is in so it's not just my safety, it's the safety of my wife and baby. It's the safety of anyone else who has this type of vehicle with these issues. Understandably it's always the drivers responsibility to pay attention to the road and surroundings but there's nothing the driver can do if the vehicle randomly shuts off or stops or slams on the brakes or another type of malfunction while out on the road. This vehicle has been in and out of the dealership 5 times now for three different things, every time it's picked up, the problem is still there or comes back within days. It's a pain moving all the baby gear back and forth, on top of the rentals we have been given have been so small, you can't even fit a stroller and groceries per-say in the trunk.

Our car one day showed several illuminated dash lights regarding brake system, along with several pop up warnings. We took it to a Chevrolet dealer for service. They’ve had it for 54 days. They’ve confirmed widespread brake system and electrical system failure, but even after escalating to corporate tech assistance, there is no progress nor resolution available. We were told they have at least a dozen others with this same issue. It is wildly inappropriate that there has not been a recall issued as this is a serious safety defect. We demand a buyback from GM for putting this death trap on the market knowing they had these issues with 2024 models but continuing to roll 2025 and 2026 models with the same issues.

I purchased a brand-new 2025 Chevrolet Traverse and have been dealing with a loud brake squeal that makes the vehicle sound like it has worn-out brakes. I’ve taken it to two different Chevrolet dealerships, and instead of fixing the issue, I’ve repeatedly been told that this is a common problem with the 2025 Traverse and that many owners are experiencing the same thing. I’ve been given multiple explanations, including weather conditions and the vehicle needing to warm up, but no actual solution. I was even told there is currently no fix available through GM and that replacing the brake pads will not resolve the problem. What is most frustrating is that everyone seems to acknowledge the issue while also telling customers to simply live with it. This is a brand-new vehicle, and customers should not be expected to accept a known brake defect as normal. Very disappointed with both the dealership experience and GM’s response to what appears to be a widespread issue.

NHTSA Defect Report (Initial Portal Filing) Manufacturer Target: General Motors (GM) Filer: [XXX] Classification: Mechanical Defect & Administrative Evasion Narrative for Submission I am filing this formal defect report regarding a catastrophic, systemic safety failure present in the 2025 Chevrolet Traverse architecture (VIN: [XXX]), manufactured by General Motors. The vehicle was originally purchased at AutoNation Timonium. THE SAFETY DEFECT AND TELEMETRY PROOF On March 18, 2026, the vehicle suffered a total failure of the transmission and drivetrain systems. It was immediately surrendered to Preston Chevrolet, where it remained completely out of service for 34 consecutive days. GM's own OnStar Diagnostic Telemetry automatically dispatched critical fault alerts while the vehicle was stranded, explicitly logging the following irrefutable failure codes: DTC U1962 (PCM - Engine and Transmission System): Warning stated: "System transferring power to the drive wheels not performing as expected." This indicates a catastrophic decoupling or failure to transfer motive power. If this failure occurs at highway speeds, it results in a total loss of propulsion, creating an extreme rear-end collision hazard. DTC U0452 (VIU - OnStar System): A simultaneous failure in the Wireless Communication and Safety system, meaning that when the drivetrain catastrophically fails, the vehicle's automated emergency SOS and crash-reporting telemetry is actively blocked or compromised. ELEVATION TO ADMINISTRATIVE EVASION General Motors and its authorized dealer network were provided with formal written notice of this defect. The 30-day statutory right to cure window fully expired without any mechanical resolution. Rather than deploying engineering solutions to rectify the severe safety defects they released into the public domain, GM has instead deployed aggressive legal maneuvers designed to evade accountability.

This indicates a catastrophic decoupling or failure to transfer motive power. If this failure occurs at highway speeds, it results in a total loss of propulsion, creating an extreme rear-end collision hazard. DTC U0452 (VIU - OnStar System): A simultaneous failure in the Wireless Communication and Safety system, meaning that when the drivetrain catastrophically fails, the vehicle's automated emergency SOS and crash-reporting telemetry is actively blocked or compromised. ELEVATION TO ADMINISTRATIVE EVASION General Motors and its authorized dealer network were provided with formal written notice of this defect. The 30-day statutory right to cure window fully expired without any mechanical resolution. Rather than deploying engineering solutions to rectify the severe safety defects they released into the public domain, GM has instead deployed aggressive legal maneuvers designed to evade accountability.

ELECTRICAL SYSTEM
I go to turn on the car on a Friday night and it won’t turn on. I got multiple failures and it said fatal errors take to dealer immediately. I brought the car to the dealer and they said the control panel needs to be replaced and they’re estimating at least a month. I’m one of four cars on a lot that need work for the same exact issue.
