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.

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.

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.

When placed in park the DIC will intermittenly indicate "Shift To Park". At that point, I am not certain whether or not the vehicle is in park. It will often go into accessory mode when this happens. I cannot turn the vehicle completely off at this point. I need to shift it from park to reverse or drive and then back into park. It may take several attempts for it to register that the vehicle is actually in park. The problem is occurring more and more frequently over time. I am about to take it to the dealer for repairs. I believe this is a common problem with many GM vehicles and they ought to fix it under a recall notice.

Shit 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.

ENGINE
Approximately three weeks ago, our 2020 Chevrolet Blazer's check engine light came on. It has a little over 63,000 miles on it. I took it to a private service garage where they diagnosed the code as P0128, or coolant system issue. They concluded that it was the thermostat. I did some checking on the warranty and it turns out that the warranty on this car expired at 61,066 miles. I then took it to Serra Chevrolet in Grand Blanc, MI where they diagnosed the same error code, or P0128. They took the car back to give me a service estimate and when they returned they diagnosed not only the thermostat as defective. This has become a common problem with this car and the 3.6 liter engine in particular. We have been told that this is a "known issue" by two different General Motors dealerships, specifically in their respective service departments. However, the owners are now having to pay for the complete replacement, both parts and labor, for these issues. Given the fact that these are a known issue, it seems to me that these need to be elevated to at least a bulletin, if not a full recall. The repair and replacement for the thermostat and sensor is in excess of $1,000. Again, since this is a known issue, it is my belief that General Motors should pay these expenses.

Intermittent Shift to Park Message Displayed While Vehicle in Park. I am seeing an intermittent Shift to Park message when the vehicle has been shifted into Park, and the ignition has been turned to the Off position. My car model is a push-to-start/stop ignition type and this issue prevents me from turning off the car at times. I am having the vehicle serviced currently at my local chevrolet dealership but being subject to a diagnostic fee of $175. A message shows up on the instrument cluster screen stating "Shift to Park," however, the shifter is already in the Park position. Potential cause: The cause of the condition may be that the park switch in the transmission control (shifter) assembly is not pulling the BCM signal low to electronically show that the vehicle is in the Park position.

We have a 2020 Blazer that will occasionally show "Shift to Park" error message and won't allow us to turn off the motor. Searching this issue, we see many people have the same problem and GM makes us pay to repair the problem.The dealer said the shift control module had to be replaced. It cost us almost $300.00 to repair. GM Service Bulletin No.: 19-NA-206 has been issued but no recall has been issued by NHTSA. There are also several lawsuits filed but we have been unable to see the results of those lawsuits. Please make GM pay and/or reimburse for these repairs. We live in Wiscons
