I have had repeated failures of all the door locks in my Yukon. They will only work manually not with the auto lock feature. Safety is a concern as you need to remember to lock the door manually and then unlock it manually to get in the car. The auto door lock feature (locking at 5 mph or above) also does not work inviting a car jacking incident. I have had 3 replaced under warranty and now a 4th door is affected.

2008 GMC Yukon door actuators going out repetitively. I have to have two actuators replaced at about $400 each for nearly $800. Two failures out of four actuators is aa totally unacceptable failure rate. This is a serious defect. The fact that the manual unlatch is un reachable makes this issue even more outrageous. Manually unlocking the door instead of being able to use my key remote is not easy. One needs to crawl in the back seat to unlatch the back door. This need serious attention! this is a pain and causes me to seriously consider buying a different brand. Do what you wish GM. Your loss down the road as I will tell as many as I can to find another vehicle to buy.
