2020 Chevrolet Traverse

My Autostop feature failed to work and did not restart my car on 2 occasions. 1) My kids and I was a stop sign at an intersection and the car would not turn back on. I had my truck towed. The next business day they told me it started on it own. 2) I was dropping my kids off at camp out of town and came to a red light. My truck would not restart. I was in the middle of the street. The police has to push me to safety until the tow truck driver arrived. After towing my truck 100 miles to the dealer near my home it started back up. The next day the dealer mis informed me that it was a programming that was coming up. I had to pay that fee plus diagnostics. When going out to test my truck the dealer experience the same issue. A severity case had to be opened to determine the solution to fix the issue. It took about 4 days. This issue is very concerning as I and my children safety was at risk while driving. I asked about turning the feature off but was told it's a state emissions law to have it on so they could not help me.

The front intermediate exhaust pipe mounting bracket weld fractured at the engine manifold, causing the exhaust pipe to break completely loose. We can now actively smell raw exhaust fumes inside the passenger cabin while operating the vehicle, creating an immediate safety hazard for carbon monoxide poisoning and driver disorientation. Additionally, the heavy steel exhaust system is completely unsupported at the front, creating an imminent risk of the pipe falling and dragging on the roadway at highway speeds, which could cause a catastrophic crash. The vehicle began getting progressively louder during cold weather between late 2025 and early 2026. A certified Chevrolet dealership technician officially inspected the vehicle, filmed an inspection video confirming this exact structural failure, and attempted to submit it for warranty coverage. GM Corporate denied the claim solely because my VIN is excluded from Special Coverage N212356540, despite the vehicle suffering from the identical manufacturing defect described in the bulletin. I possess the official dealer repair receipt and the technician's inspection video as proof.

I am filing a complaint regarding a persistent safety defect widely known as the "Shift to Park" issue. For over a year, my 2020 Chevrolet Traverse, VIN [XXX] has repeatedly displayed a "Shift to Park" warning message on the instrument cluster when the vehicle is placed in Park and the engine shutoff button is pressed. This occurs multiple times weekly. Despite the vehicle physically being in Park, the internal shifter sensor fails to recognize the gear position. This defect prevents the vehicle from shutting down properly, leaving the electrical system active and causing severe battery drain. Furthermore, because the vehicle does not recognize it is in Park, it creates a roll away risk if the driver exits assuming the vehicle is fully secured. General Motors is aware of this widespread component failure across this vehicle platform but refuses to issue a safety recall or cover the repair costs out of warranty. This is a systemic manufacturing defect that presents a clear financial and safety hazard to consumers. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
