4 Power Train problem

Failure Date: 09/18/2025

Shift to park warning comes on every time I put my car into park. I can give the gear shift a hard tap so it can go into park and my car will turn off. I feel like after a period of tapping the great shift it will turn into a bigger problem.

The battery wasn't being charged which caused some problems. However, it was the alternator that was bad. Since the battery wasn't being charged and the alternator was failing, there were problems with steering and engine power which almost caused a collision at highway speeds.

7 Power Train problem

Failure Date: 09/21/2024

I bought this 2021 Chevrolet Traverse on January 4th 2021. Since owning this vehicle the transmission has always skipped and sputtered. We have done regular maintenance on it. But at 115,000 miles it seems to get worse and really shift hard or skip while trying to go into each gear. There is no information on maintenance for the transmission other than taking it to the dealership, which is really bizarre and unreasonable because dealerships take to long and some can be without. We have also noticed on a couple different occasions that the reverse lights were on when it was in park. The parking brake also likes to set when someone opens or closes a door. We are not sure what the problem is. But would like this transmission to be fixed.

The contact owns a 2021 Chevrolet Traverse. The contact stated that while driving approximately 45 mph and stopping at a red light, the vehicle accelerated but failed to exceed 20 mph. The vehicle was taken to a dealer; however, the failure could not be replicated. The contact stated that on another occasion, while stopped and attempting to make a left turn onto a highway at 75 mph, the vehicle failed to accelerate above 20 mph. The vehicle was taken to a dealer, where it was diagnosed, and it was determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 54,000.

9 Power Train problem

Failure Date: 11/19/2021

Occasionally when putting the SUV in reverse, the car does not go into gear. I'll hit the gas and nothing and then all of the sudden it goes into gear. It's almost like it's in a delay sometimes I'll have to put into drive and then reverse for it to go into gear.

10 Power Train problem

Failure Date: 05/29/2021

With just 1,085 miles on a new 2021 Chevrolet Traverse rs the 9 speed automatic transmission began to fail. It feels as if it skips and there is a distinct shudder as it shifts in the higher gears. The transmission also appears to labor as the vehicle ascends even the smallest change in grade. Research of these issues shows its a noted prblem with the gm 9 speed automatic transmission.
