The passenger power door lock fails to un-lock or lock when accessed with the key fob. The malfunction recurred sporadically. When putting vehicle into drive (or when vehicle is turned off) the door doesn't lock or unlock on the passenger side. Other door locks are starting to have same problem. The mileage of vehicle was 27,000 and door lock problems began March 17, 2014. Have read other reports on internet websites stating this is a common problem on 2005 to 2012 Buick Lacrosse vehicles and possibly other GM vehicles. This is a potential safety hazard if doors fail to unlock in the event of a wreck, etc.

The power door locks do not work either with door switches or the remote fab. Only way to lock or unlock doors is to manually lock or unlock doors, except one door which will lock and unlock with key. Remote start doesn't work because door can't be locked with fab. Took to dealer and was told that 3 doors needed to have the actuators replaced. Priced over $750. Dealer, emerson Chevy-Buick offered no assistance. It seems to me that there are problems with the control unit that sends signals to actuators, both by door switches and the fab. Based on the complaints filed I am not alone. This very expensive problem, but a severe safety issue as driver's door does not unlock when key removed after stopping.-[xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

We have a problem with our automatic power door locks and the remote start feature. They don't work, either by key fob or the power door lock buttons in the car. The only way we can lock our doors is manually. We took to the dealer believing it to be just the drivers door but they told us all our door lock actuators needed to be replaced, close to $1000 repair with no guarantee that the actuators are the true problem. After going on the NHTSA site I see that we are not alone with these problem. I can understand a actuator going bad, but not all of them at one time. I am a former dealership gsm and very aware of "normal wear and tear" and "defects". I've never in my 35 years in the business seen this with door locks. I was insulted by their offer to repair them.

Remote, remote starter (rke) fob for car stopped working properly. Replaced batteries even though dic did not show batteries needed changing. This maybe a problem also. Sometimes it works, sometimes it doesn't. worked perfectly fine, then problems started. 99% of the time it will not start the car. 50% of the time it will or will not, lock or unlock car. I have tried resetting and/or personalizing keys & fob through dic center. Car will sound horn to show it has been reset properly, but isn't. still does not work properly also when using rke, the door lock knob will not come up all the way and the door is not unlocked. Also, the door lick know will not go down all the way if I use the rke fob. If I use the key to unlock the door, the door knob will come up all the way and the door will unlock. If I use the rke fob to lock the door, the door knob will not go down all the way and the door will not be locked. I have tried using the fob away from all possible interference which I do not think is the problems, it still only works sometimes.
