I'm getting a "Shift to Park" error message. Lights and dinging sound will not turn off during this. I have to restart the car and shift the car from Park, neutral, drive and reverse. It takes sometimes numerous tries to get it to show in park. The problem is getting worse as time goes on. More frequent and harder to get to go into Park.

My 2020 Chevy Blazer began demonstrating possible problems with the transmission in November 2021 which have continued to date. The RPMs will rapidly increase and the car will feel as if it is jolting forward. If driving below 20 mphs, when I try to accelerate to a higher speed, the car will drag and then skip forward. I have videos showing this and have taken it to the dealership on two occasions but it couldn't be replicated and no codes show during diagnositics. The car is currently being repaired (at the dealership since 3/18/22) due to 3 separate concerns that are co-occuring which seems quite strange to me. The thermostat has gone bad, causing my check engine light to come on while driving (and having to have it towed). The car is also not recognize my remote key to operate the car. I am also getting "steering assist reduced" notifications while driving. I had the battery replaced 3 weeks ago because that was felt to be the cause of the steering assist notice, but after 1 week the notices started occurring again. I will also occasionally get "ECM" notices while driving. I don't see how all of this could be happening at the same time and it not be indicative of a more major Powertrain issue. I do not feel safe driving the car, even when these separate issues are repaired because I am fearful of the core, underlying cause.

I pulled in my driveway which is on a slight incline. I turned the vehicle off but the transmission was still in drive. Not realizing this I stepped out of the vehicle and the vehicle started rolling back down my driveway across the sidewalk and into the street. Had there been anyone walking on the sidewalk the vehicle would have hit them or there could have been an accident in the street. I called the dealership where I got the car and And all they could offer was that you-??re not supposed to turn off the car in drive. I know you-??re not supposed to turn the vehicle off in drive but it happens and has happened several times to me and I-??m sure to others also. I think this is a major design flaw as I have seen that on Ford vehicles when you turn the vehicle off in drive the transmission automatically goes into park.

My vehicle idiot lights were flashing and the car felt as if it was going to stall on the road. Dealer said it was a faulty P6. Now when driving the car the entertainment unit locked up. Radio could not be changed, volume lowered. Pedals on steering column don't work. Even when car was shut off the radio still played and would cut off. Called my dealership. The earliest my Chevy dealer can look at it is next week.

The contact owns a 2020 Chevrolet Blazer. The contact stated that after driving into the garage, the engine was turned off but the transmission was left in the drive position. The contact mentioned that the brake was intended to engage in order for the vehicle not to move forward or backward. After exiting the vehicle moments later the vehicle began to roll backward out of the garage. The contact immediately attempted to stop the vehicle from rolling into the neighbor's home by grabbing the driver's side mirror. The contact was able to prevent the crash from occurring but in the process had sustained injuries to the left shoulder, neck, and back and both the left and right hip and knees which required medical treatment. The cause of the failure was not determined. The local dealer was notified of the incident but no assistance was offered. The manufacturer was not notified. The failure mileage was 4,400

With approximately 1500 miles on the vehicle, the Blazer's automatic transmission failed while driving. I was stopped at a red light. When the light turned green, I proceeded slowly through the intersection in a left turn. As soon as I left the intersection, just as the vehicle would typically up-shift, the RPM spiked, the vehicle jolted forward, and the check engine light came on. After the initial jolt, the vehicle would not shift out of first gear. I found a safe place to park and stopped the engine. Upon restarting, the engine light remained on and, though I could put the car in drive, the vehicle would not shift out of first gear. Moreover, when I tried to engage reverse, the car remained in neutral. I had it towed to a Chevrolet dealership which informed me GM has a bulletin on the transmission requiring technicians not to attempt to repair it, but to install a new transmission.
