2020 Chevrolet Blazer

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

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.

This vehicle is currently on its third radiator since it was purchased, 4 years ago. That’s almost 1 radiator per year. The vehicle also has transmission issues on the highway. The dealer replaced the torque converter but vehicle is still hesitant and bucking on the highway. This vehicle only has 64,000 KM and would cost thousands in repairs if it wasn’t under warranty.

The "steering assist reduced; drive with care" notification began coming on the dash with significant changes in outdoor temperature, as of last fall 2023. The temperature gauge on the dash would then not work and would remain at cold. Eventually the check engine light will come on however all of this will clear when the outdoor weather is stable again. As I live in MN you can imagine there are many variations to our temperatures. This occurred at the beginning of fall 2023, then winter 2023, then spring 2024. It is clear from consult with mechanics that this is all related to the thermostat being stuck open/closed. This is a very well documented issue for Blazers and I would even refer you to [XXX] which has pages and pages of both concerns related to this issue as well as radiator cracks; which I am dealing with also. This car has less than 60,000 on it! The radiators are also obviously faulty in these Blazers as well given the amount of people needing to replace these before 60,000. Some even reporting replacement under 30,000 miles which is ridiculous for a $52,000 vehicle. I would also direct you to a Facebook group of Blazer owners and the complaints about these two issues are rampant. (2019+ Chevy Blazer Official Group) [XXX] I had an appointment at Rosedale Chevrolet in MN on [XXX] and after diagnostics, and all of the above was confirmed. This issue poses a safety risk given the potential impact to the steering assist, air conditioning in hot temperatures, the car overheating and engine damage which WOULD be covered under the powertrain warranty, as well as the potential of being stranded due to a break down. This issue appears to be primed for a class action lawsuit. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
