Sierra 2500

  • 106,000 miles
The door lock actuator on the driver's door will not work or only partially work at times. Sometimes it works, sometimes it does not work and some times it half engages so the door can be half way opened, but the latch is still engaged so it cannot be opened all the way. My concern is that the door will not be locked when I think it is if I depend on the electric lock. It doesn't matter if I use the keyless entry or the electric button on the interior if it's not working, neither operate the lock. I am concerned about theft of personal belongings, or worse, my entire vehicle if the actuator does not lock the door as intended. If the electronic portion doesn't work and I have left the vehicle running while locked, I must use the keyless entry to unlock the other doors and enter the vehicle via another door and reach over to manually unlock my driver door. Another concern is that the others will stop working as the driver door has and I will not be able to get into my vehicle. These scenarios have presented themselves after the vehicle has been sitting, after a short or long drive as well. There doesn't seem to be any time that you are safe from it not occurring.

  • 65,000 miles
At approximately 65,000 miles the passenger side door lock actuator quit working. The lock does not operate with the automatic door lock on the driver side door lock function or the keypad. At approximately 110,000 miles the rear driver side door lock actuator also quit working. This is a highly unsafe situation on many scales especially since there are no keyholes on those doors.

Sierra 2500 4WD 8-cyl

  • 39,200 miles
I have a 2009 GMC Sierra 2500 with 70,000 miles. At 39,200 miles, the actuator on the front drivers side door lock failed. Then at about 46,000 miles the actuator on the rear drivers side door lock failed. My door locks no longer automatically lock and unlock which creates a safety hazard, particularly in the case of the rear door lock because it cannot be locked or unlocked by the driver without exiting the vehicle and crawling through from the passenger side. If you don't manually lock the rear door, a young child could open the unlocked door while the vehicle is in motion; but if you manually lock the rear door, you cannot get a child out quickly in the event of an accident because it is impossible to access the lock without crawling through from the passenger side. Door lock actuator failures seem to be a common problem on 2009 General Motors trucks. My father also has a 2009 GMC Sierra 2500, and one of the front door lock actuators failed on it. I had a 2009 Chevrolet Silverado 3500 truck for use by my staff and one of the rear door lock actuators failed on it. A friend has a 2009 Chevrolet Silverado 1500, and one front and one rear door lock actuator failed on his vehicle. And, a google search led me to many postings and complaints related to door lock actuator failures on 2009 General Motors trucks and SUVS. I have been unable to convince my GM dealer to correct this defect - their estimated cost to replace the two actuators is approximately $800 which I simply cannot afford to pay.

Sierra 2500 8-cyl

  • 37,500 miles
I have a 2009 GMC Sierra 2500 with 39,200 miles. My door lock actuator quit working, so my door no longer automatically locks and unlocks which I consider to be a safety hazard. I noted on-line that this seems to be a very common problem in GMC trucks, Tahoe, and Suburban - and I even have friends and family members that have had the very same problem with their GM trucks. Because this is so very common, and to me is a safety issue, it seems like GM should be addressing this. I inquired with the dealer, and the cost for a single door lock is well over $200. Based on what I've been reading, I can expect the remaining locks to go out over time. I respectfully request that NHTSA look into this matter as I believe it is affecting many others and is a safety hazard.
