2022 Chevrolet Traverse: check engine light

Filed Nov 1, 2026 · TX

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

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.

The contact owns a 2022 Chevrolet Traverse. The contact stated that while driving in first gear, the vehicle would independently enter limp mode as the check engine light would appear on the instrument panel. Due to the vehicle failing to accelerate above first gear, the contact would be forced to restart the vehicle as the vehicle would then resume normal operation. The contact stated that the vehicle had been taken to the dealer nine times due to the failure. The dealer had failed to duplicate the failure; however, when using a code reader, a message for the transmission control module would appear. Despite the dealer replacing both the transmission control module and wire harness attached to the module, the failure had persisted. The dealer had requested a traveling engineer to inspect the vehicle where unknown repairs were performed on the vehicle. The vehicle did appear to be repaired after the initial repair; however, the failure recently returned. The manufacturer had yet to be notified of the failure. The vehicle had not been repaired. The failure mileage was approximately 28,000

Both the front AND REAR exhaust pipes are cracked and broken with holes in them where the SINGLE bracket that secures both pipes mounts. There was special coverage issued to repair, but the special coverage only identifies the front pipe. The rear pipe is essentially dangling from the upstream catalytic converter, which also appears to be cracked due to the same underlying issue. If the vehicle doors are open, exhaust fumes will enter, rather than be expelled to the rear of vehicle. This pipe can essentially finish cracking and fall off into the roadway. The check engine light did not come on until these components broke. The problem is vast across many of these vehicles as reported to me by an owner of an independent service center as well as technicians who work at certified GM dealerships. The vehicle is available for inspection upon request. I currently still drive it, but its just a matter of time before a heaping hunk of metal pipe falls onto the roadway and causes an accident. The rear pipe is almost completely separated from the remaining exhaust pipe between the upstream and downstream catalytic converters at the bracket location before the flex pipe.

Check engine light came on. Chevy traverse lost power and would not shift past 45 miles an hour. Once parked a bad bucking when put into reverse and loss of power or the vehicle would not move and revved as if out of gear despite being put into gear. Had vehicle towed to Hubert Vester Chevrolet in Wilson NC where we purchased it with no remedy because symptoms would not replicate for the two weeks they had the vehicle. We drove it for a week, and the same thing happened again. Bucking started when slowing down. Towed to Phelps Chevrolet Greenville NC with same results of no repair or diagnoses after they kept it for three weeks. Neither dealership would provide a loaner vehicle. Vehicle is under extended drivetrain and bumper to bumper 100,000-mile warranties with no remedy for the issue. We are afraid to drive the vehicle but making payments on it. My personal code reader purchased from Wal-Mart scanned a P2715 Pressure control solenoid D stuck on and P0700 transmission control system. However, the dealerships would not accept the information for repairing the vehicle saying they were showing as past check engine light stored codes. Invoices for both unresolved incidents are attached. Vester applied for changing the transmission fluid with our warranty but unsure if it was completed.

Wife was driving my kids to school this am. Driving up a slight hill on a speed limit 55 road vehicle started slowing down and wouldn’t accelerate. Stopped for a traffic light and it very slowly accelerated like a manual transmission stuck in a higher gear. Check engine light went on. I Was able to drive the traverse to the local gmc/Buick dealer which mentioned they were able to download some codes about possible transmission failure - super dangerous and very concerning for a ~1.5 year old vehicle with under 13,000 miles. This could be a major safety issue. Vehicle left at dealer, at this time no confirmed diagnosis but dealer acknowledged there’s a problem.

The failure reoccurred, and the contact pressed the OnStar button; however, was informed the vehicle has not sent a failure message or check engine indication. The failure reoccurred continuously; then The OnStar service had a tow truck arrive at the last failure. As the vehicle was placed onto the flatbed, approximately 5 gallons of gasoline leaked out. The manufacturer was notified of the failure. The failure mileage was 437.
