My computers and cell phones were hacked and the harassment didn't stop until I disconnected onstar. I never had a account to this. Transmission went out during the harassment they knew and heard everything I did.
- Rowlett, TX, USA
The sunroof leaks and causes electrical problems. Suddenly while driving the power steering gears, rack, and bushings are defective causing the power steering to go out during low speeds. Tried having it replaced under the recall, however, 9 months later the same thing happened and nobody wants to fix it or allows for the dealer to replace it again. This is a major safety feature that should never be acceptable! also, the transmission already had to be replaced and is going out again. The manufacture made a faulty vehicle and should be held accountable for these parts and the labor not to mention the inconvenience of having to fight with the dealer and GM to get the problem corrected.

Going down the expressway at 70 mph. Vehicle started hesitating and wouldn't go. I had to pull off to the shoulder of road in a construction zone. Had it towed to the closeset mechanic.

- Claeremore, OK, USA
Upon entering the highway the 2007 Acadia would not shift either into or out of 3rd gear, I'm not sure. I could not tell what was happening and when I determined this was not going to correct itself I exited the highway. I've recieved a letter from GM stating that vehicles equiped with 6T70 and 6T75 6 speed automatic transmissions are experiencing cracked or fractured wave plates. This clearly is a faulty part as it is occurring on many versions of this vehicle and has been upgraded. I was lucky in that it was only me in the auto and not the entire family when this happened. Very dangerous.
- Raymore, MO, USA
Trans went out shortly after purchase, alternator went out shortly after purchase, needed new wave plate, needed new alternator, sun roofs leak water through the interior lighting and down both A-posts. Continues to run after shut off and key removed. Slips gears, will not upshift.
- Littleton, CO, USA
I bought a new GMC Acadia in 2007. January 8, 2008 GMC did a software upgrade to my transmission. At that point my mileage dropped about 6 miles per gallon and did not shift as nice as original. In late summer of 2014 I notice that my transmission was not right. On September 16, 2014 I had to replace the transmission at a cost of $3,999 at only 123,228 miles. This car was built and advertised to pull boats and campers. I have not pulled anything ever with the car. In March of 2015 I received a letter from GMC that they would reimburse 2007 GMC Acadia owners if they have had problems with the transmission. The car must be under 10 years old and under 120,000 miles. My car was under 10 years old, but over on mileage by 3,228 miles. GMC would not cover any of it. It is pretty poor when a car company can not build a $40,000 car with a transmission that would last.
