All four doors would not lock or unlock by pressing the lock button on either front doors or by using the remote when stopped. It scares me as a parent of a seven year old that the doors may not lock when needed and my child could accidentally open the door when driving anywhere at any speed. For the safety of my family and friends this really concerns me because if we were in an accident what if the doors couldn't unlock by button or manually or lock to keep passengers in while driving. In my opinion this is a safety hazard that really needs to be investigated by GM and an action taken into affect to correct this faulty issue or parts.

3 of 4 door lock actuators have failed. Called Chevy and had me bring to dealership to have tested and dealership did confirm that was actuators. Chevy not willing to cover cost of replacing faulty parts. I am unable to use door locks on 3 of my 4 doors.

3 of 4 electric door locks do not work. Multiple message boards with people complaining about door lock actuators no longer working on this model/year. Safety concern as I have to climb into back seat to unlock doors when my children are in the back.

My rear passenger door does not lock/unlock. Huge safety hazard. The door can be opened while the vehicle is traveling 70 mph. This is also a security issue. I can lock the vehicle with the key fob only to learn that the rear door will not lock. If I lock it manually, then it will not open with the key fob. This is a huge inconvenience, I have to unlock it manually. The dealer stated that this is a very common problem. Internet research shows that this has happened to thousands of people. This should be a recall!!!

Bought 2500 hd crew cab Silverado, 2008. Researched known problems online with door actuators. Apparently they begin to fail with less than 5000 miles on certain trucks. I see this as a safety hazard and a security problem. In case of a crash the locks on the rear doors will not work and must be unlocked manually which may be impossible depending on the damage, the manual locks are on the farthest point back from the driver which makes them very hard to reach from the front of the truck. They also do not lock when the key fob or electric lock button is pushed in the truck, must be locked manually. This problem is extremely well known and GM refuses to recall this item even though it is a clear safety risk. If I have a fire or an accident I would not be able to get my daughter out of the back of the truck and GM would be getting one hell of a lawsuit. Likewise if anything gets stolen out of my truck due to the locks not working I will also be starting a lawsuit against GM. Every manufacturer wants to get ever penny they can out of people without taking responsibility for hiring the lowest bidder for crucial parts on their vehicles and then refuses to stand behind them. Some people I have talked to have replaced these door actuators 4+ times all the way around their vehicle. Unacceptable.

Power door locks on my 2008 Chevy Silverado crew cab quit working on both drivers side doors. I only have 25,000 miles on the truck and have not returned it back to the dealer yet as the problem just started this weekend. I have checked the web and of course this is a very common occurance that Chevy has tended to sweep under the rug and had not made a recall for this. This is a major inconvience and is a major safety hazard as well. I have my fingers crossed that the dealer will fix this problem but I have my doubts. My 3 year bumper to bumper warranty ran out in August. I purchased a new truck to avoid these types of aggravations and now regreting that decision.

Have lost operable of passenger rear door lock, and the other three doors on my crew cab Silverado have begun to have the issues of not locking/unlocking when set by system or on demand by person driving the truck. This doesn't allow for the doors to lock/unlock after vehicle is moved to and from the parked position. This could be considered a safety issue.

- Gulfport, MS, USA

All 4 lock actuators failed and with that, the body control module cannot properly work the security system. The power locks inside the vehicle work intermittently and seem to randomly unlock one of my doors. The automatic door lock when you put the car in gear does not work. This causes multiple safety risks. 1) failure of auto lock could result in carjacking and passenger ejection during a wreck 2) failure of security system to arm and alarm could lead to theft 3) intermittent and random unlocking of one door when unexpected results an unsecured vehicle despite deliberate owner effort and expectation of security and can result in theft and ejection4) since only the driver door has a key lock mechanism, I have to crawl through the cab to unlock back doors resulting in body strain and injury. Do this*** google "2008 Chevy Silverado lock actuator failure. See how many thousands of vehicles this is happening to. I have never had one actuator fail, and in this vehicle it has been all 4 and that is happening to thousands. The cost is $1000 to repair and there is a "national back order" so they have to be aware of the problem. Please help us little guys and make this right.
