"Shift to Park" displayed in my DIC when vehicle is in park, parking brake is set and trying to turn off the vehicle. Vehicle would not turn off. Had to wait 5-10 minutes each time this happened before I could safely turn off the vehicle. This happens intermittently and holds me hostage as the vehicle won't shut off and is therefore unsafe to leave.

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.

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.

My retractable sunroof suddenly explosively broke. I was approaching a red stop light at low speed. I heard what I thought was a gunshot or vehicle backfiring. As I drove on, I heard wind whistling. I thought my passenger side window wasn-??t closed. I lowered then jraised it. At that point, I heard my sunroof disintegrate. Luckily, the headliner kept the glass from raining down on me. If this had happened at highway speed, it could-??ve been a real problem.
