2008 GMC Sierra: doors won't lock, open or latch

Filed Apr 7, 2016 · Electrical · 99,550 miles · NY

Purchased my 2008 gmc sierra truck in november 2015 after having for only 5 months driver side door lock will only lock or unlock sometime, making it unsafe if you needed to exit quickly due to accident or fire. Seen many other post about same problem. Should be a recall on this.

All 4 door locks do not lock/unlock unless done manually. Big safety issue!!! Notice a lot of complaints on this maybe it is time for a recall.

All four door locks were intermittently inoperative & only able to function manually from the inside. Taken to dealer and diagnosed as internal failure in door lock assemblies/actuators. All four door lock assemblies were replaced at a customer cost of $900+. This is my second gmc vehicle that has had the same problem and after searching the internet this seems to be a fairly common problem. Even the dealership mechanic mentioned surprise that it has not been recalled or gmc has not been forced to fix the problem considering how often he had personally diagnosed & fixed this same problem. This is definitely a safety issue as the customer is unable to rely on the door lock system or lock/unlock the doors as usual. Multiple times, my vehicle sat at the airport for days unlocked because of this failure. Similarly, my toddler-aged children were able to open the doors to the backseat with the vehicle in motion due to the failure in the automatic assembly.

We have had three of the power locks go out - first was front passenger, which was under warranty and covered free of charge, so was the second - the front drivers side. But, the rear passenger side went out a year later and now they will not cover it under warranty. My concern is that, having small children, I have had them locked inside the vehicle and the unlock doesn't work, so I have to climb through to access the door lock. In an event of an emergency, where time is of essence - this is a severe issue.

Erratic door lock behavior. Passenger and rear driver side door will not lock or unlock consistently. The passenger side lock not locking resulted in the theft of a handgun from my vehicle. This deficiency leaves the vehicle susceptible to theft, carjacking, doors coming open on impact. Passengers, especially children are at risk of opening the vehicle door while in motion. In the event of an emergency the doors effected can not be unlocked from other than the manual latch button to aid passengers.

The drivers side interior door handle will not open the drivers side door. The window has to be rolled down in order to open the door from the outside.... Based on the gmc forums I have read this happens to a lot of people. The replacement costs can run from $200-$800 due to plastic pieces and cables being used that melt and break easily. This is very dangerous because if someone were to ever get into an accident and they need to get out of the vehicle quickly they will not be able to open the driver side door if that is the only option to be able to get out. They will have to kick the window out in order to open the door with the outside handle. I am the original owner of the truck and am very disappointed this has appended at such a low mileage.

Passenger door lock stopped working. Only way to unlock door, is by reaching across seat and lift lock button. This is unsafe in case of an accident, where the drivers door is unable to be used for exit, and the passenger door must be used.

All of my power door locks are not working. This is a very dangerous situation when you have children in the back seat and they try to open the door while in transit. I have had the locks repaired once already while the truck was under warranty and now they are faulty again. This is not what I paid for when I chose to trust in gmc. I think a lemon law lawsuit is in order if they don't resolve this issue free of charge. Gmc is risking the lives of not only my children but every other family that trusted in gmc.
