2020 Chevrolet Blazer

The contact owns a 2020 Chevrolet Blazer. The contact stated while attempting to shift to park, the engine remained running, and the message "Shift to Park" was displayed. A mechanic was called to diagnose the vehicle, and the contact was informed that the transmission control, shifter harness, inline shifter wiring harness jumper, park switch, and other related components were faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 77,340.

At around 55,000 miles my Blazer began to show error codes for “Steering Assist Reduced” and “ESC”. After 60,000 it began to intermittently populate the Check Engine Light paired with the "Steering Assist Reduced" message. Then, the engine fan would turn on high, auto-start when breaking would disable, and the steering would become more stiff. Finally, I was able to get a scan on the code and found out that it was my thermostat. After taking it to my local Chevy dealer I was quoted $1100 to repair. When I called my local mechanic I was told they could fix it for cheaper, but they were unable to find an OEM thermostat in stock which usually means there's a widespread issue with that part. Upon further research, I've found a plethora of complaints online where others with Chevy vehicles are experiencing the same issue. This causes: -Greater fuel consumption -Risk for the engine to overheat -Stiffened steering which could cause accidents

The contact owns a 2020 Chevrolet Blazer. The contact stated that upon reaching the destination and shifting the vehicle into park, a warning message displayed reading "Please shift to Park." After, the contact observed that he was unable to switch the vehicle off. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was 128,000.

Radiator was found to be leaking. Now thermostat is sticking. This could have caused my engine to overheat and catch fire. I have had a mechanical shop replace the radiator but could not afford to replace the thermostat yet. I had been seeing warning lights and still see warnings after radiator was replaced. They said “Steering Assist Reduced” and “ESC” and the engine light came on. I went to Auto Zone Dec 9th to have them tell me what was wrong. I took to shop on Dec 13th. I have googled several complaints about Chevy blazers having this particular problems. This is apparently a widespread issue that needs to be recalled.

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.

Questions Answered Below: What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle is at a GM Dealership now and is available for inspection. I have not authorized repairs as of yet. I am being told by the dealership: The ball joint on the control arm on the left side seized snapping the axle shaft - causing the tire to to turn out. The dealership has suggested: Mechanical repair costs $1,850, Plus an additional $2,000 due to wheel well damage caused by the failure. Has the problem been reproduced or confirmed by a dealer or independent service center? I am being told by the dealership: The ball joint on the control arm on the left side seized snapping the axle shaft - causing the tire to to turn out. How was your safety or the safety of others put at risk? Due to my slow speed turning out of the parking lot ~10 mph - the vehicle came to a sudden halt. However, had this occurred while driving any faster - it would have been very dangerous and put myself and others at significant risk. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It was towed by AAA and has been inspected by the GM Dealership. That is the only inspection thus far. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Earlier in the day while pulling out of a parking spot and turning the wheel to the left I thought I felt some type of resistance then it went away as I started driving. No other symptoms or warning prior to the failure.
