When putting the vehicle into park, we are receiving a -??Shift to Park-?? error. This issue appears to be common among thousands of General Motors vehicles. However, the dealership is unable to assist us because the repair bulletin only applies to the 2019 model year and does not include the 2020 model year. Despite this, the issue we are experiencing is identical to the one reported for the 2019 model.

Vehicle keeps throwing -??steering assistance reduced please drive with care-?? message. It causes my car fan to constantly run. It also causes the coolant gauge to not work the needle drops below that cool like it-??s not on and then the car won-??t blow cold air from the vents. This message tells me that something could be wrong with the steering which puts my safety at risk. This issue has been happening to me on and off for months now and there are multiple complaints of multiple Chevy owners having the same problem this issue needs to be addressed.

After putting the vehicle into park I received an error message "action required shift vehicle to park". I was then unable to completely shut the vehicle off or lock the doors and the alarm and notice continued to sound. I ended up spending over $1200 in repair costs and car rental to have the vehicle fixed.

2020 Chevy Blazer - Shift to Park while Gear is already in Park: While putting the gear in park, the warning chime to shift it into park is initiated. It has happened 3 to 4 times in the past three days. I took the vehicle to the Local Chevy Dealership. The Service Team/Dept. diagnosed that the Transmission Shifter Unit Assembly must be replaced. The 2019 Chevy Blazer had these issues which prompted a TSB/Recall however it wasn't extended to the 2020-year models and Chevy Dealership refused to include it as a warranted repair which just passed 44,000 miles. This is a safety issue, and it should be replaced without additional cost to customer as this issue was already identified as a safety concern in 2019, however Chevy does not want to identify the issue as a covered repair per the manufactures warranty.

After I shift into park and press the button to turn my vehicle off, I receive a message on the dash that states "shift to park" and my vehicle will not turn off. This has happened on several occasions, but does not happen every time I attempt to turn my vehicle off. When I do receive the message, I usually have to restart my vehicle and move the shift out of park and back into park before I can turn the vehicle off. Sometimes, I am able to get the error message to go away by jiggling the shift.

When car is put in park and cut off the vehicle doesnt recognize its in park and a light comes on saying -??shift to park-??. I have to keep pushing gear shift forward repeatedly even though its in park already. The car will not fully turn off till this error message is cleared. Ive had the car checked multiple times and the dealership states there is no code registering for this problem so they cannot fix problem so i cant get it fixed. Ive researched this and it is a known issue for multiple chevy models. Service mgr also stated its s known issue in multiple models.

My car, since I bought it on and off, would say -??shift to park-??. It was on park. Lights and radio stays on. Now it does it constantly. I need to ensure my car is on park because I have my kids on the car!!! To make sure it is on park, I put it on drive and back to park like 2 times just to ensure I have it on park. Now every single time I get try to turn off the car, it says shift to park and my lights and radio stays on for quite a bit. My cousin had the same problem with her other Chevrolet vehicles. If this is common, why has it not been recalled? I have a 2020 Chevy Blazer RS.

The backup camera in my preowned 2020 Chevy Blazer RS stopped operating within 7 months of purchasing Jan 13, 2024. It was replaced by local dealership. However, less than two weeks, it stopped working again. It's a safety feature that's not operational concerned may lead to accident. I did some research online where other owners have experienced the same problem.

Sh*t to Park issue. Whenever I put my 2020 Chevy Blazer into park I get a "Shift to Park" error and the car will not turn off. I have to jiggle the shifter and hope that the vehicle appropriately engages into a park mode so I am able to turn the vehicle off. From doing a lot of research I have ascertaioned this is a KNOWN PROBLEM to GM. I URGE AN IMMEDIATE RECALL for these GM vehicles so this issue can be fixed.

6/12/2024 In Damon Parking lot in Rochester MN. Going less than 10 miles an hr- cars in front of me and behind me looking for a parking spot. Stop and go at times. Went to turn corner to go from one level to the next and my BLAZER took off "like a bullet". No control over accelerated speed- hit outer cement wall and slammed into 2 parked empty SUVS. Could not go any farther. The 2 SUVs slammed into cement wall in front of them. Injuries to both my passenger and myself. I have no idea what happened - it was so fast- I do know I had no control over accelerated rate causing accident. My 2020 Chevy Blazer was totaled- It was inspected by American National Insurance CO. Absolutely no warnings. Police report did not include any witness. Blazer is in the hands of the Insurance Co. Chevy Blazer took off like a bullet - could not stop it!!Police report 24026393 Rochester Police Dept Unable to upload. Checked no police report below so I could continue report.

AC blowing warm air when all the way on low and on full blast. Brought to repair shop and found that there was no freon, the radiator had a hole and the condensor had a hole. Had to have radiator, condensor and thermostat replaced along with adding freon. The total for this was $2077.02 I should not be having these problem with a 2020 Blazer. I purchased this vehicle on 28 May 2020.
