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 M 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
