Consumer Description

While i was driving a code came on my dashboard that read "Steering assist is reduced drive with care". Soon after my check engine light came on. I pulled over not knowing what was happening. I took it to the garage to have it looked at and the mechanic stated that there are over 1000 gmc customers with this same issue and that the thermostat is stuck open. Which may cause major malfunction or even blow the engine. I looked up recalls for my vehicle and there are none but gmc issued a recall on other vehicles for this same issue. How do I get help here?
