2020 Chevrolet Traverse problems

“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.”

“There is a well known exhaust issue with the catalytic converter and the separating manifold and no recall has been issue yet. It causes the vehicle to lose pressure and shuts off in the middle of traffic. The seat belt secure locks are malfunctioning and could cause loss of life in the event of an accident.”

“My 2020 Chevrolet Traverse is experiencing a SHIFT to PARK issue. When the car is placed into PARK, the electrical system does not recognize it and will not shut off the vehicle. There is a defect with the button trigger that allows the gear shifter to move and it is not being recognized. The quick fix is to press this button around 15 times to reset it. Sometimes this works but when on an incline, it does not. It takes turning the vehicle on and off a few times to have this registered. The estimated cost to replace the gear shifter is around $600 to $900 dollars. Please have this item recalled.”
