“Engine thermostat not functioning properly, therefore the display stayed on cold and would not show temp. It also cause the fan to run fast to cool engine. The AC would not cool and reduce power steering assist error message comes on. This is a known problem by GM and there is a recall for this issue on many of these vehicles, other GMC and Cadillac vehicles. Our vehicle should be added to the recall list!”
“Receive error message about Power steering that shuts off AC and Temperature gauges. Happens constantly when vehicle is driven on freeway. Requires the battery to be disconnected and it resets until the next time.”
“2020 GMC Acadia bucks/hesitates when I take off or slow down and speed back up. Mechanic looked at it can see engine is having random misfires. We have tried plugs, transmission fluid, looked at everything we could think of. The condition improves if I put into AWD but still exists and worsens for a period of time after it shifts back into FWD mode. My mechanic has done a lot of research and found that one possible issue was a stretched timing chain but since it is out of warranty I just couldn't afford to have them tear it down it is an enormous job to see if that was the issue. It also lines up with other known issues like the auto stop issues and possibly a fuel pump issue. I have seen many people complaining online about this particular issue but not many on here and no recalls on my vehicle regarding the known issues”
