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.

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 $750.00. 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).
