    Rearview mirror camera failed causing rearview mirror monitor to fail creating a blind spot while trying to back up. When i went back to visually inspect the camera assembly nothing looked damaged and when i physically touched the camera it was extremely hot to the touch to the point of burning my finger tip.

    The contact owns a 2020 Chevrolet Blazer. The contact stated that while driving at various highways speeds, the vehicle was very unstable to steer and was swaying from side to side. The vehicle was taken to the local dealer who was unable to identify a failure. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 1,000.

    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.

    My car is in park and when I cut the car off, it tells me I need to shift to park. This means I have to restart the car and try again. It happens multiple times and has been occurring often.

    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.

    On Tuesday August 9, 2022 at 0800, I dropped off my 2020 Blazer. I informed the staff that the seat base was not cooling as well as when I bought it, something is wrong with the transmission, and the screen keeps freezing. I was informed at that time by Amanda Carroll that it may take up to 72 hours to perform a diagnostic on the Blazer due to only one diagnostic tech at this time. The diagnostic had not been performed. We then told her that I had to return to work on Monday August 15th, can we get a loaner vehicle. We were told that due to the shortage in microchips, they did not have any vehicles available. “I am sorry”. We had not heard anything from anyone in regards to the status of the Blazer, so we went in person to the Service department on Saturday August 13, 2022 at 1130. My husband then asked about the status of the Blazer, was a diagnostic performed? She informed us, that a diagnostic was not performed. The only diagnostic tech called out, but he did come in on his day off to help. They know something is wrong with the Blazer, but were not able to perform the diagnostic. I then informed her that it has been over 96 hours since I dropped off the Blazer, and nothing had been done. I have to make a choice of driving a possibly dangerous vehicle or lose my job. But since a diagnostic was not performed, who knows what is wrong with the Blazer. I was informed from the BBB to contact Sean Jordan at All American Chevrolet of Killeen to discuss this matter. I contacted Mr. Jordan and we made arrangements to have the Blazer brought in on September 3rd at 0800. I took the Blazer into Chevrolet at 0800 and was informed by the employee, that I only had 45 miles until my warrantee was out. I told the staff employee, when I turned in the Blazer last month, I still had a warrantee and that Mr. Jordan would have to take care of that issue. Nothing was done and we left. I am out of characters to finish the complaint.
