When I parked and tried to turn off car it would continue to run. I had to put it in park and drive back to park several times before car would turn off. There-??s a recall for this issue on other blazers and I feel 2020 blazers should be included. The dealer replaced the shifter assembly, cleared OTC

We have experienced 2 issues that are very well known issues, I will list them here. First, is the Shift to Park issue, that involves an electrical switch and wiring harness on the shifter assembly. Second, is regarding a "driver assist reduced drive with care" alert message that includes Diagnostic Trouble Code (DTC) P0128, but is actually related to either the engine cooling sensor or the cooling thermostat housing assembly. Both issues are very well known, and many owners have had these issues.

I am getting the message "Shift to Park" displayed while vehicle in park after turning the vehicle off. Looking online, it seems to be a common issue with Blazers as well as other GM vehicles. I found online that "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." If this is such a common issue on similar vehicle to mine since 2018 it appears, why is this not a Recall already?!

When you shift it into park, it often doesn-??t recognize that it-??s in park and begins to roll backwards. This doesn-??t happen every single time but at least twice a week and I have to use the parking break.

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.

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 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

The valve on the thermostat stuck open causing the vehicle to go into a default mode. Ramping the radiator to full high and the thermostat will not come off of C. It has caused an issue with the A/C not blowing cold and also causes a message to pop up upon starting the vehicle stating that steering assistance is reduced, drive with caution. Upon doing research, thousands of people have had this similar issue with different model chevys as well. And the part is on the back side of the engine so injectors and air intakes have to be removed to preform any work to a $100 part.

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 service advisor at the Chevrolet dealership denied a repair to my abs control module because it was a -??known issue-??. He told my wife and I our car is unsafe to drive And still wants to give it back to us. Other Gm vehicles have recalls open for the same issue one needs to be open for this. Abs lights and multiple others no brakes or random braking.

Rearview camera and back up camera constantly not functioning and going black while and motion or backing up. Car acts like there is something in front of it (like a wall) on certain roads and does not want to accelerate to turn/pull out from a stopped position. I have had this vehicle for 2 months. I have had a car prior to this that did this before and stopped and left me stranded on a busy road and caused an accident. I can't believe this car is acting like this!

After driving the vehicle for random periods of time and at random speeds, all the TPMS sensors will give alarms and then register as dashes on the dashboard. It gives alarms for each tire as each tire goes out until all of them go out. They will reset after a random period of time and start to show the pressure again.
