The thermostat housing fails and is a known issue which causes the car to overheat and they said it will start of fire or shut down and loss of steering assist. The dealerships know about the issue and GMC does nothing leaving people with large repair bills or inoperable cars. The system won't let me upload my receipts here is the part #12678780 I was told by the dealership this is a known issue and they my emissions warranty only covers the thermostat but not the housing, but that they are 1 piece, playing games. . . . .
The thermostat stops working and my a/c stops blowing cold air, and driving assist stops and engine light goes on. It is a rampant problem among GMC Acadias with no reason or fix. Please advise.
