2008 GMC Sierra Latches, locks and linkages Problems

“I have to lock and unlock both of my passenger side doors manually, because the locks doesn't work with the key fob nor inside the vehicle. I feel like this is a safety issue that GM should recognize because someone could have values stolen out of their vehicles if not have the vehicle stolen if they forget to manually lock doors when there is a passenger in the vehicle.”

“My 2008 Gmc Sierra denali's automatic locks have failed on three of the four doors. I didn't realize they were not engaging until I took two children to dinner and had one of them open the door without unlocking the door. I had the child safety locks engaged and thought I would be safe, but it turns out the locks never engaged (thus, making the child locks irrelevant). This is an issue beyond inconvenience.”

“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.”

“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. …”
