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.
