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.
ELECTRICAL SYSTEM,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE06/20/2026
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.

SERVICE BRAKES06/10/2026
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.
POWER TRAIN,ELECTRICAL SYSTEM,ENGINE06/07/2026
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.

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.
