2006 Chevrolet Tahoe w/ 3rd row seating. The liftgate lock failed without any indication that it was going out. This is very fearful for our family for which we have small children who May become trapped and unable to escape this vehicle in the event of an accident. I read 11 complaints online from other consumers with this same matter. Chevrolet are aware that these complaints are out there and know the risk in which are involved. Why should they wait until someone is seriously injured or a death occurs due to a defect on their end. I would hate for this to happen to anyone and I hope that you all can look into this. Not to mention that this particular vehicle doesn't have a key entry to unlock it as well. Please look into recalling what others have identified as the actuator. Thank you, [redacted]
We are unable to open the rear liftgate with the fob. So, we continued to look for a key latch and to our shock we realized it could not be unlocked manually. After a lot of frustration and anguish of trying to load groceries through the back seat and having to literally go over 3rd row seat to put groceries in cargo area, we thought how awful it would be if we needed to exit out the back door in case of an accident. We discovered we could not unlock or open the liftgate from the inside either. It gave me a very uneasy feeling as we transport children to and from school. This problem is definitely a safety issue. We contacted a local Chevrolet dealer and they are not willing to even check our vehicle unless we fork over $120.00+ and then we have to wait a week for them to even look at it. …
Liftgate unlock quit working at around 63000 miles. There is no manual or key operated way to unlock the liftgate. It failed in the locked position which has the potential to trap someone inside in the event of an emergency. The only way to open was to crawl inside the back end of the vehicle, rip the plastic trim panels off that cover the mechanism, and then move the actuator by hand. When I took to the dealer to check out he wanted over $125.00 to diagnose problem, $500 to replace the lock actuator, or $200.00 to unlock with no repair to locking mechanism. I read numerous other complaints of this problem on this vehicle. GM should really acknowledge and address this problem.
2006 Chevrolet Tahoe z71. Rear liftgate fails to unlock. Keyring and door panel buttons unlock all doors, but rear liftgate remains locked. There is no key hole access on the outside of the liftgate and there is no manual lock release in the vehicle. Liftgate panels had to be removed from the inside of the vehicle in order to access the locking mechanism and move the lock to disengage and open the liftgate. Further inspection and testing showed that locking motor works to lock the liftgate but the mechanism fails to align properly when attempting to unlock, preventing mechanism from disengaging.

2006 Chevy Tahoe, 63,000 miles, rear liftgate stuck in locked position. No manual way to open, in the event of an accident/emergency you can not exit from the rear seriously increasing the potential time to exit vehicle. From all the blog posts etc... This appears to be a defect in the locking mechanism itself. The right thing to do would be to identify correction and replace before someone is seriously injured or killed-one death would be one too many.
Tl contact owns a 2006 Chevrolet Tahoe. The contact could not open the liftgate with the keyless entry remote. There was no keyhole to open the liftgate manually, which he considered to be a safety risk. Also, if someone were in the vehicle, there was nothing in the passenger compartment to press to exit from the rear of the vehicle. The dealer stated that the remote needed to be replaced. The current and failure mileages were approximately 63,000.
2006 Tahoe rear liftgate will not unlock, nor will window open. It doesn't make any noise. There is no key hole to open manually. My grandchildren often ride in the rear seats, and they would be trapped in a collision. There is no inside handle, either. My sister-in-law has an identical model in which this has also happened. GM should in our estimation, recall and fix this problem. The most efficient fix would be to have key access to unlock.
