2022 Chevrolet Traverse power train problems

“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 contact owns a 2022 Chevrolet Traverse. The contact stated that while driving at 50 MPH, the vehicle began to shake violently, and all warning lights illuminated. The vehicle was taken to a dealer, where a diagnosis determined that the transmission had failed and required replacement. The failure mileage was 105,000.”

“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.”

“In 2024, at 49000 miles, my transmission gave out and wouldnt allow me to accelerate. GM replaced the transmission. This past week, while driving on a busy hwy, it happened again. I narrowly avoided an accident and had to get my car towed a hour home. These are the codes P0700, P2732, P0746”

“electrical, drivetrain, powertrain. While driving the vehicle a message popped up on the speedometer saying service battery chargeing system and battery saver mode. the is the second time that those messages have come up in the four years of ownership with the first time being in 2024. The second issue we have had with this vehicle was injectors going bad and causing a bad misfire making driveability rough. We have gone through three O2 sensors in the past 4 years. we have replaced the alternator and are fixing to replace it again. the driverside axle seal leaked. transmission slips bad. there is a current random misfire. Back in may of 2025 we were driving to Florida from missouri and had to slam on the brakes and when we released the brake the car refused to move and when i pressed the gas harder there was a loud bang like we had been hit but it was like the brakes had locked up completely. It shudders bad when starting. Two months ago the steering locked up while driving. Vehicle has been inspected several times by the dealer we bought it from but driving this vehicle is becoming my families worst nightmare.”

“After turning the car on, engaging reverse, and then retuning back to park (driver stepped out of vehicle once in park) the vehicle reversed 60 feet on its on through a parking lot with 2 children inside of the car (disengaged from park on its own while vehicle was running). The vehicle was ultimately stopped by a tree with damage to the tailgate and rear. The gear shift selector remained in park for the entire incident. A claim was filed with GM and the Traverse was initially labeled as a “intermittent failure” in my May 2026 claim interview. Post GM inspection, the vehicle is now deemed “operational” (no repairs from GM) and being returned to my family as of July 2026.”
