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)

The contact owns a 2025 Chevrolet Traverse. While the contact’s wife was driving approximately 5 MPH, the brakes independently activated while the accelerator pedal was depressed. The ABS, traction control, check engine, collision avoidance, and other unknown warning lights illuminated. An audible alert chimed erroneously without a pedestrian nearby. Due to the failure, the contact’s chest struck the steering wheel. A passenger seated in the front passenger’s side seat experienced mental distress. The vehicle was taken to a local dealer, where it was diagnosed, and DTC: P053D, C055F, P25A2, and 25NA240 were retrieved. The vehicle was repaired under warranty; however, the failure persisted. The vehicle was taken back to the same local dealer and scanned with an OBD2 scanner, and the failures were confirmed. The manufacturer was made aware of the failure.

My 2016 Chevy Traverse LT with 108,750 miles had issues with the rear brake lights, and the Traction Control light would come on and the Traction Control turns off. A message appears on the dash that shows Service StabiliTrak. When I drive the vehicle to accelerate it shakes, jerks and shudders, and then it rides fine for a bit but the Traction Control is still off. I also noticed that the cruise control doesn't work either. I decided to wait a few more days hoping it would clear out, which it did for a day but the problem returned. I took the Traverse to AutoZone to use an OBD2 scanner and it showed that there is an issue with the braking switch (code C0161-00 ABS Brake Switch Circuit). A local mechanic replaced a fuse and the brake switch but the Traction Control/StabiliTrak issue hasn't been fixed. He's tried everything but the problem won't go away. Apparently this an ongoing problem with many Traverses.

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.

My 2019 Chevy Traverse prior to "The Storm" when I left work and approached my vehicle someone left a not in my windshield wipers stating that my horn was honking every 15 seconds it was a long shift so by the time I got to my vehicle my battery was dead. I got a jump from a co-worker allowed my alternator to charge my battery, and it was fine (so I thought). Then the day after "The Storm" happened, my Traverse went haywire displaying multiple signs of electronic failures while driving on a major highway: Service ESC, ABS disabled, Traction control disabled, Power steering disabled, Horn honked continuously, windows won't roll down, Key fob unresponsive, Manual lock/ unlock switch unresponsive, A/C on but doesn't blow cold, infotainment system on, Cluster Hazard light indicators on but lights aren't illuminated, Windshield Wipers on max speed unprompted while spraying continuously. I pulled over, placed the vehicle in "park", turned the vehicle off, safely exited to realize my vehicle was still running, got back into the vehicle where I was greeted by a prompt that said to place the vehicle in park to turn it off. I attempted to shift but it was immovable, called a tow truck. Every time after dealership visits/ repairs my vehicle shutoff while moving. It's been to the dealership 3 times (4 to include tomorrow) I've also connected an OBD2 Scanner to run a diagnostic after the last visit and these faults appeared almost instantly. Work done so far: x2 BCM replacements (w/ flashed software) x1 Battery replacement x1 Keyless Entry Module replacement x1 Driver door lock/unlock switch replacement x3-->4 tow trucks Over $3,000 in expenses
