2025 Chevrolet Traverse electrical problems

Vehicle: 2025 Chevrolet Traverse LT FWD VIN: [XXX] Purchase Date: XXX Incident Date: XXX Mileage: 35,975 INCIDENT DESCRIPTION: On Fr XXX, just seven days after purchasing this vehicle from Enterprise Car Sales, I started my 2025 Chevrolet Traverse and was immediately presented with multiple serious braking and vehicle safety-system warnings. The primary warning stated: "BRAKE ASSIST FAILURE. PRESS HARD TO BRAKE. SPEED LIMITED." Additional warnings included: - Service ESC (Electronic Stability Control) - ABS warning light illuminated - Traction/stability control warning - Forward Collision System Unavailable - Red BRAKE warning illuminated - Check Engine light illuminated These warnings appeared during the same startup event while the vehicle was stationary. SAFETY CONCERNS: I am extremely concerned that a vehicle with fewer than 36,000 miles is reporting a potential failure of its power-assisted braking system, along with simultaneous malfunctions involving ABS, stability control, and forward collision protection. The dashboard specifically instructed me to press harder to brake and indicated that vehicle speed was limited. This raises serious concerns about braking performance and the ability to safely stop the vehicle, particularly during an emergency. I am aware of the federal safety agency investigation EA26006 concerning potential electronic braking-system failures in certain General Motors vehicles, including the Chevrolet Traverse. The symptoms reported in that investigation appear similar to the warnings displayed by my vehicle. The underlying cause has not yet been confirmed. MANUFACTURER NOTIFICATION: I formally reported this incident to Chevrolet/General Motors. GM Case Number: XXX Photographs documenting the warnings and mileage are available. REQUEST: I request that the federal safety agency document this incident as a potential vehicle safety defect and evaluate whether it relates to existing complaints or investigations INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Two issues have been occurring with my car amongst many others, but these are the most recent my vehicle has all seatbelt sensors go off despite no one else being in the vehicle, but me the driver my sensor does not go off. It will not stop beeping or screaming at me until I have to pull over turn off my car turn it back on and essentially reset the system. The other thing my car intermittently when I shifted into park at a full stop for example like in my driveway my foot is fully pressed on the brake, and my car will completely shut off and jerk the car forward and backwards when I shift into park, the engine shuts off but the car was never turned off just shifted in to park. and then resets my entire car all the electrical panels, the dashboard everything goes off-line, then comes back online and I get a message that says to reset driver window, lower window all the way down and raise it back up to which I later found that this meant the entire car program was just reset and started over… This is really frustrating and I fear of something like this happening while I’m actively driving It is not letting me upload the video

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.

Wife had car sitting over night from doing a EMS shift. Went out to car in morning to start to return home and when car started ABS light, ECS light, Brake Light, and Collision light came on. This has resulted in no ABS or safety features. Called dealer and can't look at car for over a month. There was no mention about not driving. If the wife needs ABS or front radar, she will not have it resulting in a more serious accident.

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.

the federal safety agency 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.
