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.

The toe links on my vehicle are bad and needs to be replaced. They broke as I was driving. Almost caused me to lose control and almost wreck. Thankfully there were no other cars around. I see this is a recall for GMC’s but for some reason not my vin number. Not understanding why if I have the same problem on vehicles that were recalled.

Blind spot warning light is not working. There is a previous recall for this for 2014-2017 GMC Acadia Models for the same issue. The issue has not clearly been fixed with models after 2017
