Without warning, the brake pedal on my 2019 Chevy Blazer became hard, almost as if the car was turned off. I was unable to stop and slowly rolled into the back of a semi stopped at a stoplight. This was moments after exiting off of a major highway and could have been much worse. The car was taken to a mechanic and it was determined to be a failure with the brake booster. GM has issued recalls for this problem in several other models but the Blazer has been excluded. Based on online forums and complaints of multiple other Blazer owners, it seems obvious that Blazers should have been included in the recall.

8 out of 10 times I put the vehicle in park I receive a "shift to park" alert. I have to put it in another gear several times before it recognizes it is parked. Sometimes flicking the shifter push-in piece on the bottom will work. I am unsure if the car is officially parked when I don't get this message.

When in park my car says “shift to park” when it has clearly been shifted into park. I’ve read forums and it’s the same issue for many Chevrolet cars

There is a current recall in place #19-NA-206 that I believe should include my vehicles vin number. There is an intermittent shift to park message that appears when the vehicle had been shifted into park and the ignition has been turned to off position. Making it unsafe as I am not sure if the vehicle is actually in park or not.

I cannot shut off my vehicle. When I turn off engine warning message and alert binging tells me to shift to park. The vehicle is in park but vehicle does not register that it’s in park. I’m stuck in vehicle which will not stop alerts and runs down battery. This is a hazardous situation. I can’t tell if car is actually engaged in park or not. This started happening intermittently over the last month but now it happens 8 times out of 10 when I try to shut off the vehicle.

The starter and flex plate failed (cracked) on the vehicle while on the road due to the auto start stop feature. When I stopped for a red light, the car made a loud grinding noise and would not restart leaving me stranded in traffic. The 2019 Blazer has the auto start stop feature which cannot be disabled and likely results in excess wear and tear. GM updated the 2020 model to allow the function to be disabled. GM has a number of technical bulletins highlighting both starter and flex plate issues, the first being in 2020. Both the starter and flex plate failures were verified by Reeder Chevrolet in Knoxville TN. I've asked for the flex plate to be provided when repair is complete. There were no warnings via check engine lights or any strange noises prior to the failure.
