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…

After turning the vehicle completely off and restarting it, the braking system temporarily reverted to normal function before randomly failing again on a subsequent drive. The vehicle was brought to a local brake shop where it was dangerously misdiagnosed, and…
Received a power steering reduced notice when starting the car, noticed shortly after driving the temperature gauge had not moved from its resting position. A few trips later it still had not moved and the check engine light came on. Mechanic looked at it said it may be a sensor quoted $1k to fix. A few days later it randomly started working and the light went off so I did not have it fixed. About 4 months later the same code displayed on the dash with the same issues. This time I noticed the ac would not work either it only blew out hot air. Also the fan under the hood turns on as soon as the…
