2025 Chevrolet Traverse

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.

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.

At approximately 30,000 miles, upon starting my 2025 Chevrolet Traverse LT, the brake pedal traveled completely to the floorboards with zero resistance. Simultaneously, the 'Service Brake Assist' warning message appeared. This loss of hydraulic pressure occurred while stationary. This follows a dealership visit one week prior for a 'glitchy' check engine light that was dismissed by service staff.The vehicle is being towed via flatbed to the dealership as it is unsafe to operate. Additionally, the vehicle has exhibited abnormally 'touchy' brake response and a persistent high-pitched squeal from the front assembly since purchase. These symptoms suggest a failure of the e-Boost braking system and/or internal master cylinder seals, consistent with Service Update N242482170. This defect poses an immediate risk of total brake failure during operation.

We drove the Traverse 55 miles to a baseball game. When we got in the car to return home several warning lights appeared on the instrument display and there was an audible warning sound. The message “Service ESC” and “Brake assist failure” appeared on the instrument display panel. We couldn’t find a dealership that was open on Saturday so we cautiously drove 55 miles home. The brake pedal was hard to push and had to be pushed all the way to the floor to stop the vehicle. We could not drive faster than 62 MPH on the way home and I had to start braking early in order to be able to come to a complete stop at stop lights. Cruise control isn’t working either and the audible alarm sounds off every couple of minutes. We took the car to our local dealership this morning.

Vehicle: 2025 Chevrolet Traverse On [XXX] at approximately [XXX], while driving south on [XXX] , my vehicle suddenly shut off without warning resulting in a complete electrical failure. During this event, I lost the ability to accelerate, activate hazard lights, unlock doors, open or close windows, or use the OnStar system. The vehicle restarted briefly but then shut off two additional times before I could safely move it off the road. There were no warning messages or signals prior to this incident. This created a serious and immediate safety hazard, as I was unable to alert other drivers or exit the vehicle during the failure. I am requesting a formal investigation into this issue, documentation as a safety defect, and immediate corrective action. This incident poses a significant risk to driver and passenger safety.

The first component to fail was the brake booster module which controls the ABS, forward collision, adaptive braking, adaptive cruise, traction control system, etc. The malfunction started when the forward collision assist activated to prevent me from hitting a deer in the road. We avoided hitting the deer but all of those lights came on immediately. We contact Friendship Chevrolet the dealer we bought the car from had us bring it in to be checked. They confirmed the defective Module and said that it was a reported issue that GM had it's engineers looking at. They said they would have to wait for the part to arrive, advised that we could continue to drive the car even though there was a major malfunction with the critical braking systems. did not offer any type of loaner to ensure my family's safety. We had to wait for more than 30 days for them to receive the part and complete the repair still driving this unsafe vehicle because we had no other choice considering how high the MSRP & payment is on the vehicle. Once the repair was finally completed we immediately began to notice that the brakes were consistently screeching when in slow moving traffic like car rider pick up line. I reported the issue to the dealership and they gave me the answer that it was due to a more abrasive brake pad being used due to it being a passenger vehicle and it's weight. We continued to deal with the squeaking for months then we noticed a coolant leak. Dealership again said had to wait for part. After they did not contact me back I contacted GM and opened a case. When they got it in I also had them change the brakes out of my own pocket. Now the brakes squeak anytime pressure is applied and when coming to a complete stop they grind so loud you can hear and feel them digging in. GM still says nothing is wrong and brakes are a maintenance charge and are not covered for any reason. I feel the vehicle is still extremely unsafe and my family is at risk of possible crash.

Turned on vehicle on 3/2/2026 and received a message stating "Anti-lock break system failure. Drive slow and stop cautiously." I test drove my vehicle in my local neighborhood and discovered that my brakes were only functioning at about 20% and would only respond if the brake petal was pressed all the way down. My car was towed to the local dealership to be assessed and was determined to need Reservoir 4.651, Cylinder 4.650, and Fluid 8.800 when it was picked up on 3/6/2026. Under further review of this report I came to discover a class action lawsuit for this vehicle make and model relating to cylinder part #85762161. I am unsure if my original part was that part number, but my experience closely mirrors other's that have been reported for the same issue and part repair. The part that was also replaced in my vehicle after the repair was part #85762161. Some individuals in this lawsuit have reported 100% brake failure. I am fearful to continue driving the vehicle knowing that there could still be ongoing issues with the part that directly relates to the brakes.

Initially, the engine would intermittently fail to start and at times would not start at all. I took the vehicle to a certified Chevrolet service center, where the battery was tested and found to be functioning properly. They later concluded that a faulty front-view camera was disrupting the electrical system and ordered a replacement (my first visit was Friday, 9/26/25). I took the car home for the weekend due to family obligations. On Monday, 9/29, while driving back to the service center, the engine suddenly shut off on a local road. The brakes went completely to the floor for 3–5 seconds before the engine restarted—just before I nearly collided with another vehicle at a red light. I reported this immediately, and the dealership kept the car for further testing. On Thursday, 10/2, they informed me they found no additional issues and believed the camera was the root cause. However, the problem persisted. On Sunday, 10/5, while stopped at a red light at Hawthorn St. and Memorial Dr., the engine shut off again as I began to accelerate. The brakes sank to the floor, and I had no steering control for approximately 5–7 seconds before the vehicle restarted. My wife and I were extremely shaken, especially with our children in the car. On Monday, 10/6, we contacted roadside assistance to tow the vehicle back to the service center. After additional testing, we were informed that the battery had failed this time and was replaced. However, replacing the battery does not reassure us that the engine and braking system will not fail again while driving, or the brake failure would happen again when the battery is low - which poses a serious safety risk to our family. When my wife called GM to report this issue, all they offered was 200 points worth of rewards....We originally bought this car for safety, but not this has been compromised and we no longer feel safe. Thank you for your attention to this matter. I am happy to provide any additional information if needed.

Purchased the traverse January 10, 2026 with almost 26k miles on it. Approximately one month later, only 1200 miles or so into owning it, the shark fin antenna cover came off and is missing. It’s not the entire antenna that is hooked into the car, it’s only the plastic cover that covers up the electronics. This plastic piece randomly flying off the car put other motorists at risk, due to the plastic cover potentially striking another vehicles windshield distracting them from keeping their eyes on the roadway, striking another motorists vehicle causing damage to said vehicle, or even striking a person walking down the street potentially resulting in physical harm! I have talked with GM dealerships about this issues along with reading that numerous people have had the same issue, and they have yet to fix the problem.

While driving, ABS, traction control, ESC, forward collision, and AWD alerts were indicated by the car. At the time it had 10 months in service and approximately 12,800 miles accumulated. After 17 days at the dealers service department and a direct call to GM the brake master cylinder and associated components were replaced. I've seen several reports of this generation of Traverse having this same issue for other owners at low mileage. I want to file this report to ensure that NHSTA is aware of this serious safety concern that could result in loss of braking power.

The vehicle has been brought to an authorized dealership for numerous service visits related to electrical system issues that ultimately affected the braking system. During one service visit, the vehicle was returned to me with multiple active dashboard warning lights illuminated related to the braking system, including Electronic Stability Control and Automatic Emergency Braking. I questioned the presence of these warning at pickup and was advised by the dealer that the vehicle was safe to drive and that the warnings would clear on their own. After driving the vehicle for a short period, I became uncomfortable continuing to operate it with brake-related warning lights still active and returned it to the dealer. Upon further diagnosis by a service technician, it was discovered that the vehicle has significant brake system defects requiring replacement of major components, including the brake control module and master cylinder. During diagnosis, the brakes locked and the parking brake would not disengage, rendering the vehicle undrivable. No collision or injury occurred. However, the vehicle was released to me with active brake system warnings and later found to have serious brake defects. Due to the safety-critical nature of the braking system and the repeated electrical and brake-related service history, I am reporting this for documentation and review.

The vehicle was later towed to the local dealer who recharged the battery and performed a software update to the Crucial Control Module. The contact stated that three weeks later the same failure had reoccurred. The local dealer and manufacturer were notified of the failure. The failure mileage was 9,995.

Brakes have squeaked since the day we bought our brand new vehicle. I have contacted the dealers and called corporate. The answer I have received from both is”it is the material they are making the brake pads out of.” We paid over $50,000.00 for our vehicle and do not want to deal with squeaky brakes all the time. They will not do anything about it.

I own a 2025 GMC Traverse purchased in July 2025. The vehicle is experiencing ongoing electrical system issues. The GPS and OnStar systems are inoperative, including vehicle location services. The vehicle cannot connect to OnStar or detect a Wi-Fi connection. In addition, the adaptive cruise control is not functioning properly. These systems have been inoperative for approximately 4 weeks. The vehicle was taken to the dealership and I was informed that parts are required, but no repair timeline has been provided. The loss of GPS, OnStar emergency services, and adaptive cruise control presents a safety concern, as emergency response, vehicle tracking, and driver assistance features are unavailable while driving. The issue remains unresolved.

My vehicle experienced a brake system failure that rendered it unsafe to drive and required it to be towed to the dealership. I have been informed by the dealer that the issue involves a failure of the left rear brake caliper. The vehicle is currently out of service at the dealership. Because this issue affects the braking system, it is a significant safety concern.

The contact owns a 2025 Chevrolet Traverse. The contact stated that immediately after purchasing the vehicle, the vehicle experienced several electrical failures, including the On-Star module malfunctioning. The On-Star module was replaced twice. During the failures, the cruise control feature became inoperable, and the computer updates were not received. Additionally, the battery became drained several times, and the vehicle needed to be jump-started. The contact also indicated the shark fin antenna had ejected from the vehicle while driving. The vehicle also abruptly stopped while driving on several occasions, and while driving, there was an abnormal metallic scraping sound coming from the engine compartment. The radiator hose had failed, causing coolant to leak from the vehicle. The hose was replaced, and the vehicle was repaired. The manufacturer was notified of the failures. The failure mileage was 44,000.

The component that failed was the "shark fin" antenna cover. This houses the radio signal and hands free driving signals. The shark fin can be a safety concern if the cover fall off at higher speeds. The problem was reported to the dealer but was told it wasn't covered under warranty. It wasn't covered because according to them, I drive my car through automatic car washes. The antenna cover is not properly glued or clipped correctly. There has been no car failures or messages. It can cause other issues since the antenna is now exposed. Cannot give a clear answer on when the cover fell off I noticed it early December.
