2022 Chevrolet Traverse

SUPPLEMENTAL REPORT TO ADD CRITICAL SAFETY HAZARD FOR PENDING COMPLAINT. In addition to the broken bracket and cracked converter previously reported, raw exhaust fumes are now actively leaking into the passenger cabin, creating an immediate health hazard

I am filing a formal safety complaint regarding an engineering defect in the exhaust support system of the 2022 Chevrolet Traverse that creates a direct chain-reaction failure, compromising vehicle safety and emissions controls. My vehicle experienced a complete structural failure of the front exhaust pipe mounting bracket—a known manufacturing defect heavily documented by General Motors under GM Special Coverage Adjustment N242445280. When this corporate-acknowledged bracket snaps, the exhaust system loses its vital structural anchoring point. As a direct mechanical consequence, the heavy catalytic converter assembly is left completely unsupported, subjecting it to violent, unmitigated engine vibrations and structural flexing during normal operation. This extreme mechanical stress directly forced a hairline crack to split open along the welded seams of the catalytic converter inlet pipe. Safety Risk and Consequences: This defect poses an immediate safety hazard on multiple fronts: 1. Exhaust/Carbon Monoxide Leak: The structural crack in the catalytic converter assembly allows raw, unfiltered, toxic exhaust gases—including carbon monoxide—to escape directly into the engine bay, creating a severe risk of passenger cabin intrusion while the vehicle is idling or in operation. 2. Fire Hazard: The unmitigated vibration and shifting of an unanchored, cracked exhaust line running at extremely high operating temperatures (exceeding 1,200°F) near surrounding components creates an elevated risk of thermal damage or engine bay fire. 3. Engine Stall Risk: The exhaust leak introduces erratic sensor readings, triggering a check engine light, risking unexpected engine performance degradation or a sudden stall at highway speeds. General Motors is actively utilizing the restrictive text of bulletin N242445280 to dodge liability for the full scope of this failure, forcing consumers to pay thousands out-of-pocket for cracked catalytic converters that are explicitly broken as a direct

When attempting to turn off my 2022 Chevrolet Traverse, the engine shuts off, but the vehicle remains in the ON position. The vehicle does not recognize that the transmission is in Park, preventing the electrical system from shutting off completely as intended. This issue is concerning because the vehicle does not properly complete the shutdown process even though the gear selector is in Park. The vehicle's electrical systems remain on, which may result in the battery draining and could affect the vehicle's normal operation. I am concerned that this may be a defect involving the transmission Park recognition system, gear selector, or ignition and shutdown system. I am requesting that NHTSA investigate this issue to determine whether it affects other 2022 Chevrolet Traverse vehicles and whether a safety-related defect exists that requires corrective action. A vehicle should properly recognize when it is in Park and allow the driver to shut it off completely. This malfunction needs to be investigated and addressed to help prevent further problems for vehicle owners.

The transmission failed after picking up my son from daycare. I pulled on to the main road heading home. It started to speed up and suddenly started jerking back and forth causing cars behind me to slam on their brakes and then the car would not go over 15 mph. A few minutes later the check engine light came on and this is the first time it has come on. Called a tow truck and had it towed to a gm dealership they reproduced the issue and told me the transmission is bad and I need a new one because it is a sealed system it cannot be rebuilt. They quoted me $9900 for a new one and also said the transmission is on backorder with no idea when they will be available. They did not say what the labor charge was. This is outrageous for a vehicle that is less than 5 years old.
