In owners' own words

My vehicle has been throwing an error code related to the thermostat. The temperature gauge will remain on C resulting in the fan running loudly, the air conditioner not cooling the cabin of the vehicle well, and a message displaying "steering assist is reduced drive with care". When I check the fluid levels everything is fine without issue. I'm VERY frustrated and want to get rid of my Blazer ASAP. Power train

The thermostat is getting stuck open and giving me a reduced steering assist error. My safety was put at risk because of the steering assist being reduced. The problem has not been reproduced but there are many issues online about the same model, year, and mileage all having the same issue. The component is going to be inspected by a service manufacturer. There were no warning lamps prior to error. Power train

A few months ago had Blazer in for oil change. That same day check engine light came on. Was told thermostat needed to be replaced. Needed to order part. Check engine light went out then steering maybe reduced just a week ago eventually check engine light came on. Took to dealership and thermostat needed to be replaced also radiator developed a leak. Just over 60000 miles Power train

Verbatim from NHTSA filings. Complaints are unverified owner reports.
