same crap obviously a defect. back locks wont lock when pressing all locks down. sometimes works 90% of the time crawling across to manually unlock. or going back opening and manually locking doors. major inconvience consider amount of money spent on this vehicle and amount of similar incidents on here.

The power lift gate actuator stopped working. tried and after market replacement which worked for approx. 2 weeks. Ordered another from another company and it work in reverse, it would lock when you hit the unlock and unlock when you locked the vehicle. That one also only lasted approx 1 week. To buy one from the dealer is approx $450.00. I have found that this is an on going problem with many complaints so I do not know why there hasn't been any type of recall on this
