2020 CHEVROLET BLAZER Complaints

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.

Message showing on dash "Shift to Park" when the vehicle is in park. Brought to dealer and had to have the transmission control assembly replaced. The total for this was $506.23

Steering assist reduced warning came on as I was driving. Electric steering module has gone bad.Temp gage and AC stopped working as well. No accident yet but this is a KNOWN SAFETY DEFECT that needs to have a recall. The steering wheel could lock up. Force GM to recall this vechile before people die!!

Got rear ended, the front right passenger seat bent backwards and torqued right.

This is for all four of the Continental Crosscontact LX Sport tires, size P 235/ 85 R18 with about 22,800 miles on them. These were the original tires that came with our 2020 Chevrolet Blazer. While driving on dry roads the car felt like it was on marbles, wanting to wiggle on the road. We took it to our locale Chevy dealership, they took a short look at the tires, and told us to have them replaced very soon. I started do research on new tires and also found out that Continental had put out a Voluntary tire recall there, this was for 93,959 of their passenger tires. But only certain mold dates and serial numbers were on this list. We had only one of our four tires on their list. All four tires had the same wear pattern, the outside tread of each tire had worn down to approximately 0.150", with the inside of tire tread at approximately 0.205". Probably near normal wear for a 22,800 mile tire. To me the malfunction was with the outside tire breaking down and becoming weak, causing the excessive wear and unstable driving experience, putting the car at risk of accident and all passengers in it. We replaced them with Goodyear Maxlife tires. One of the tires with the serial #[XXX] was on the recall list, Continental paid for it to be returned to them, and verified that it was on recall, they are to pay us for 1/2 of its life. Contacting them again, I told them again that all the tires had the same wear pattern. They then asked for the other 3 remaining tires to inspect. After they inspected the other 3 tires they have denied any other claims of defects on those tires. I do not have any tire to show you now, but Continental's records should show the tire wear as I have stated. Of the 3 tires, 2 of the tires not recalled were A3LM WD30 dated 08-20, serial #[XXX] and [XXX], and the third tire A3LM WD30 dated 12-20 with serial #[XXX].

"Shift to Park" displayed in my DIC when vehicle is in park, parking brake is set and trying to turn off the vehicle. Vehicle would not turn off. Had to wait 5-10 minutes each time this happened before I could safely turn off the vehicle. This happens intermittently and holds me hostage as the vehicle won't shut off and is therefore unsafe to leave.

As I was driving, my engine coolant temperature gauge went from normal level down all the way pegged to C. Message appears on my dashboard "Steering Assist is Reduced. Drive with Care". Also, radiator fan continuously runs as if the air conditioner was turned on, which it was not. After searching the internet and confirmed by dealerships and the shop I had my car repaired, this same issue with the coolant temp sensor and thermostat is a very common occurrence on these generation Chevy Blazers. It just amazes me and disappoints me that this type of failure on a car happens as soon as 70,000 miles. Should last for much much longer before this type of failure happens.
