Doors locked with remote. 2nd row passenger door behind drivers door failed to actuate with remote or with door locks. Was able to work with the manual lock on the door from the inside to free the door. Once freed, the door failed to return to the closed position and remained stuck until the key fob was pushed. Repeated the lock with the key fob, door still will not actuate to the open position. Child can unlock as this bypasses the child locks on that door. Child could also get trapped in the car-could not be unlocked without manual agitation of the internal locks. Internet is full of his same issue on the same model vehicle. This is a serious hazard.

Door lock actuators. Three of four door actuators are broken and locks must be controlled manually. GMC wanted $655 to fix the two I knew were broken. GMC is well aware of the thousands of complaints of this defective part. I was not aware the third lock had failed until my son opened a back door and stepped into traffic. I was under the impression his door was locked. All I could do was scream at the top of my lungs in an attempt to keep him from getting hit by traffic. Does it take a death or several deaths before GMC recalls this defective part?!!! this is a serious safety issue when you have a child in the car and should be looked at before an injury of death occur.

Front passenger and rear passenger door locks / latch will not open unless you do it manually. Car had less than 80,000 miles when this took place. This is a dangerous situation specially when an emergency takes place and you need to exit car fast. There should be a recall.

Door lock failure, driver and rear passenger.

- Montgomery, TX, USA

The passenger door and right side rear door locks have failed. The doors have to be manually locked and unlock. I believe it to be the door lock actuators, as their are numerous complaints about this all over the internet. This is a huge safety issue. I cannot believe this has not been recalled. I have two small children and to not be able to get to them as fast as possible in an emergency is very scary. These automatic door locks are there for a reason GM knows it. I was told the cost would be around $300 per door and many of these people have had to have them replaced multiple times. This needs to be fixed free of charge with quality parts that will not fail!

Problems with power door locks. Had it with our 2000 Yukon, my 1999 Sierra, and now our 2008. The 12 volt motor which drives the locks up and down via a screwjack fails. No logical way to just change the motor. The entire assy. Must be replaced @ $153 my nearest dealer. 2nd door to fail on the 2008. Assy is stamped "made in china". this is a recurring problem and should be on a recall.

Rear driver side door lock will only open manually. The key fob and electronic mechanisms to unlock this door no longer work. The rear passenger door now operates in the same manner (it doesn't). I see a significant number of people encountering the same problem.

Drivers door lock failure. According to the auto forums on the internet, this is a widespread failure, for all doors, not just the drivers. Its an electrical wiring problem with the lock actuator. GM refuses to fix them out of warranty and has issued no recall. I read a woman's post where her toddler child almost fell out of the back seat while moving because the door failed to lock, seat belt was the only reason child survived. GM should be ashamed for not recalling this hazard.

Door locks have failed on 3 out of 4 of the doors. Sometimes in the locked position, sometimes in the unlocked position. Some postings on this topic are referencing issues with wiring harness. If the locks were to not unlock in an car accident, or god forbid rolling over down a hill that there is the potential for loss of life. There are multiple complaints regarding this on the internet. GM is well aware of these failures. I really believe this should fall into the recall catagory of vehicles.

I own a 2008 GMC Yukon. The vehicle has power door locks and the actuator on the door locks has gone out on all four doors. They replaced the first 3 under warranty, but they would not do it on the last one as vehicle was out of warranty. My son helped me install a new one in the last one, but we had to buy the parts. My sorry dealership wanted $300 to fix something that is obviously flawed in the first place. The door lock has now gone out again on a back door that they had already fixed, supposedly they will repair this one free of charge. I guess I will take it in and see if they will honor their repair warranty.

2008 GMC Yukon door actuators going out repeatedly. I have to manually unlock the door instead of being able to use my key remote as the drivers side and 2 passenger doors have gone out. This becomes a safety issue as I am at my business until 9pm and would like to unlock my door by remote.

First owner of a 2009 GMC Yukon has had 3 door lock failures, which not only qualifies under the lemon law, but also poses a major safety issue. The first door lock failed. GMC does not consider door locks as a warranty item or safety item so I was forced to pay for a replacement. The next week, another door lock failed. The dealer did not charge for the replacement. Now, a third door lock failed only 10 days after the last repair. Why is this a safety concern? my child was able to open the door while all doors were locked. Due to E failure, the door was unlocked unknowingly. My child and any child or person risks falling out of a moving vehicle. Secondly, should a car accident occur, unlocked doors could result in a door opening and ejecting the passenger leading to death. There is a flood of complaints on the web for this issue. GMC has not owned up to it, but due to the major safety issues, this should be investigated and faulty actuators and the known pattern failure in wiring harness causing the failures should be addressed as an immediate recall.
