Acadia 6-cyl

  • 83,858 miles
My 2008 GMC Acadia gave me the scare of my life. I purchased my vehicle just last month and was very proud, I have been dreaming of this car for a while. However while traveling to my sons track meet my Acadia started jerking as if it was not getting any gas and the engine started making a loud humming or buzzing noises on farm market 521. The car slowed down to about 25 miles. Despite my continuing to press the gas pedal. I ended up jerking my way onward with my hazards on. I had cars screeching and flying around me. My kids and I are a nervous wreck. The 521 does not have a shoulder to pull off on. Miles later varying speeds as low as 15 and up to 35 mph I found a gas station (thank god) & pulled over. I powered down waited a few minutes then restarted the car. It started normally but I noticed I could not go into reverse while trying to leave the parking lot. I made my way forward all seemed well but 3-4 minutes into driving on 521 the same thing happened and now my check engine light is on. I started to panic I'm not familiar with the area. This is my first time here & the 521 is the only major road on my gps. I put-putted along and finally made it to the track meet in the middle of nowhere. Called my husband to come and check the car. After his look around he thinks my transmission is going out. He took the children in the Suburban while I drove slowly ahead. Then I get a new message - engine hot idle something - I freak out and pull off as soon as I could. He ended up towing me home. I am one week past the 30 day warranty this sucks. I really love my Acadia & am very possessive of her, no one else can drive her, I don't want my kids to touch her. I take excellent care of her, she is clean, driven with love, but just don't understand what happened. I'm scheduling to take her to the shop in the morning, husbands mad but I'm hoping this can be resolved quickly.

Acadia 6-cyl

  • 72,000 miles
Engine light came on took it in to get checked the GMC dealer said it was purge valve and may be my timing chain belt! and my master cylinder was leaking into my booster, and they had to replace a sensor for the tire and service the track/stabilitrak! services came to $1000 now come 2 months later to Jan 2014 engine light is on service stabilitrak is on take it back, my timing chain needs replaced@ 74000 miles which is about a $2000 job and my transmission platelets need changed! transmission is now slipping we called GM and there is nothing they will do as I was informed these are "command problems " in these vehicles!! what!! I feel like I've been sold a lemon and no one are GM cares because these are command problems for them! never again will I buy a GM and I'm confused on how so many people have these same issues and GM is doing nothing about it! oh did I mention you can't park on a slant or an incline with a 1/4 tank of gas because your Acadia won't start! this car has been a nightmare!

Acadia 6-cyl

  • 117,245 miles
At driving speed it was noticed that Acadia began to fail to shift gears, basically on highway it is stuck in first gear and after finding a place to stop, it will now not go into reverse. Have found the edmunds, ask and numerous other sites are full of transmission complaints concerning the 2008 Acadia and it's failures. This transmission has had minor issues in past, minor leak and some whining, but this is a complete and hazardous failure while driving in traffic. I have since learned that this is a common and known issue to General Motors costing the consumers approx. $3000 to $3500 per instance. Is there nothing to be done to assist the consumers?
