Been happening for a year and a half. Muffler is very loud and rattles constantly. Getting worse over time. There is a current recall but my vin isn’t included even though my car is having the same issue.

The electronic dashboard goes black while driving. I was driving to work on the highway at highway speeds and the entire electronic dashboard went black including the hud display and the radio screen. The radio screen turned back on and auto reconnected to my phone and android auto. I was able to safely get to an exit and park, turn off the car and restart and the dash did come back on to then go black about 5 minutes later this time the hud stayed on and I was able to get to work where the car sat off for 8 hrs , when leaving work the dash stayed on. The radio screen would turn off randomly and unable to connect to a programmed cell phone via Bluetooth or data cable. I brought the vehicle in for a service and this issue plus the concern of the transmission shuddering.

Cars is not keeping track of temperature showing engine is cold after 30 minutes of driving, fan runs for extended periods of time after shutting off, check engine light comes on, steering assist alert comes in screen. All of this happens in a cycle. To stop it the battery has to be unplugged and reconnected resetting the car and everything goes back to being fine for a short period of time.

My car suddenly out of the blue started overheating. By the time I could get stopped safely and turn the car off the engine fan kept running to try to cool it down. I’ve never had any issues with my car. It only has 47,000 miles on it. I now have to have it towed to a mechanic shop to get diagnosed, but I’m hearing that it’s probably a thermostat and that the GMC Acadia’s are famous for that being a problem. I’m not sure why GMC would not do a recall on this part! this is an extremely expensive fix.
