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
Actuators failed
rear hatch door doesn't lock..all other drivers side and passenger doors DO lock
bad actuator rear door
Back passenger door lock failed. Not repaired due to cost.
I had the same problem as another visitor. When trying to open the hatch via the button on the handle (liftgate) the liftgate would sound like it was closing. If you quickly pulled you could manually open the liftgate. all other buttons did nothing (related to Liftgate). The solution I found to fix it was 1. Close everything and open the hood. 2. Detach the negative cable from the battery for at least a minute 3. Attach the negative battery cable 4. Unlock the truck and turn the key to acc (dont start it). You should hear the sound of doors clicking like they are unlocking 5. Liftgate should now work Optionally, remove the Fuse (44 i think, check the fuse guide for power lift gate) and then try and open, then plug fuse back in. I did this before turning the key so perhaps it was just the battery detaching that reset everything. I was pretty darn happy i didnt have to buy a new liftgate motor.
Door locks slow and wont lock
doors power locks wont work....doors open just with a key
Chevy dealer wants $130 to even look at the problem which they believe is the actuator in each door
Rear passenger door actuator does not work
three don t work and two still do, all at one time
Rear door will not unlock.
It will auto lock when you go into drive position and unlock when you're in park. But when you use the lock/unlock from the door or the key it will not unlock the back left door
same as the rest
Rear doors won't unlock automatically when door unlock button is used. Must be done manually.
