My son was driving down hwy 281 and all of a sudden locks started going up and down like crazy, traction control, stability track, engine light all came on and car would not accelerate. Thank goodness my fianc was with him and they managed to get home safely. The next day all the same things above plus backup camera not working and when it park, the box around p kept flashing on and off. Now car won't accel hardly at all. This is very dangerous when your out on roads. There's needs to be a recall and gmc needs to take care of their customers before someone gets killed! I have seen several posts with the same issues so what is taking gmc so long to fix their problems on vechicles?

Takata recall traction contro,l service stabilitrak, engine speed reduced light turned on in my 2011 gmc acadia. Wouldn't go no faster then 15mph on a 55 MPH road and the engine got really loud and rough. Was going 40 when the lights all came on driving down the road. This is very dangerous to drive when it keeps doing this. I'm scared to drive it now. Specially when I have a baby in the vehical with me. I'm not sure what causes it to do this. Some people say it's a glitch in the main vehicle computer, read it's a glitch in several different vehicals. This is something that seriously needs to be recalled and diagnosed and fixed immediately!

I was driving down the road with almost 1/2 a tank of gas, and I lost power suddenly, and had no control over my vehicle because the power steering and everything quit. Because I am fairly strong, I was actually able to turn off the road into a safe place, and not be stranded on a very busy two lane road. After having the car towed to paul's automotive garage, I was advised that the vehicle was out of gas.

While driving this morning I had a series of messages appear : "traction control off" , then "service stabilitrak" and then very soon after "reduced engine power". The car would still run, but would not go above approximately 20mph and struggled to maintain speed. At one point had to pull over and turn engine off to almost "reset" car to be able to continue driving to destination. This is the third time that this has happened and have had to take to the shop. I have small children that are typically in the vehicle when this happens and am concerned for their safety if this issue cannot be resolved.

Began hearing whining noise and thought it was in the engine or transmission. Took it to dealer and was told it was the power steering pump and rack and was not covered under power train warranty. I just had the "numerous" recalls repaired and now this. According to many posts on various websites, this is a common problem with gm products. Repairs are costly and should be covered under warranty, or should be recalled! This is ridiculous considering the cost of these vehicles.

Service stabilitrak, and the engine power low warning lamps illuminated followed by the vehicle slowing to 20 MPH. Vehicle taken to the repair facility where the technician diagnosed that the throttle body was defective and needed to be replaced. This same incident occurred several times previously. Engine reverting to low power is a hazard and safety issue.
