2020 CHEVROLET BLAZER Complaints

The blazer's check engine light came on and I had it scanned. The code was PO128 indicating that the engine coolant temperature is consistently below the thermostat regulating temperature. We are also getting a message on the vehicle that states the steering assist is reduced, drive with care. The car is also blowing hot air when the AC is on, the temperature gauge is staying at the lowest setting and the fans are running full blast. This seems to be a very common problem with the Chevrolet Blazer.

The contact owns a 2020 Chevrolet Blazer. The contact stated that while driving at an undisclosed speed, the steering wheel became inoperable. The contact stated that the steering wheel became difficult to turn with a reduced steering message displayed. The vehicle was taken to the dealer, where it was diagnosed that the thermostat had failed, which caused the steering wheel to fail, and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 54,000.

I have an oil leak and now they are saying both of my camshaft housing gaskets are leaking it's going to take weeks to repair cause it's such a major leak

Vehicle gives warning that steering assist is disabled. I should drive carefully. Also cooling fans run on high and temp gauge reads zero. P0128 I'd code given by computer. When code is cleared vehicle returns to normal operation. I read many, many people have this same problem with no clear correction. Many have replaced thermostat, temp sensors, and problem returns. Sounds like defective wiring to me and if it impacts steering should be an OEM problem to remedy

Almost every time I start the car up it asks me if the vehicle is a Demo. I will sign in as a user and identify the vehicle and keys, but it seems to lose some of the information when it is turned off. It has happened hundreds of times.

I started receiving the message “steering assist reduced, drive with care” although I’ve noticed no reduction in power steering. This has happened multiple times. The A/C stops working, the Temperature Gauge moves to 0 degrees and the engine fan goes to maximum speed. I have noted that this is a common issue with the Blazer.

when you put your Blazer in Park you get the warning light and chime to 'shift it into park'. So far it has happened to me 5 or 6 times in the past couple days. I can jiggle the shifter handle to get the chime to stop but it has me concerned. I have seen numerous posts about this same problem.
