NHTSA Complaint #11677536 — 2019 GMC ACADIA

Last week, the coolant gauge , on our 2019 GMC Acadia, was reading below "C".... The "Steering Assist" warning was disabled on the on-screen display and the Air conditioning stopped working. Took the car to a mechanic, who read the codes.... Mechanic stated that all symptoms were based on a defective GM thermostat. The thermostat was "stuck-open" causing the "steering assist" to be disabled as well as the A/C from being disabled as well. It seems GM has updated the part since when the series of Acadia were manufactured. After getting it repaired, at of our pockets, we researched and noticed that thousands of other GM Acadia owners had the same exact 3 symptoms: (1) malfunctioning coolant reading (2) "Steering assist" disabled (3) a defective ("stuck-open") thermostat..... Symptoms were exactly the same for all parties involved. We have owned many vehicles never had a thermostat fail before 65k Miles.... It became a safety issue since the car disables the "steering assist" based on the thermostat being stuck open. Contacted GM corporate which stated unless a recall, there would be no compensation. GM needs to make it right for the thousands of GM owners whose car has the 3.6L engine In short, this is a major issue since the car's steering system is NOT working correctly We would like a recall to be initiated. Thank you.
