Automatic door locks work sporadically on all doors. They seem to lock when the car is in drive, but will not unlock when shifted to park or when you push the power unlock button. A related problem with the front and rear driver side door where the door will not open from inside or outside. Replaced the cable in the front driver side that was corroded, now experiencing the same problem with the rear driver side. I don't want to spend $200 to replace another cable. If I pound the inside of the door just right and in the right spot, I can get it to open. The lock mechanism is not opening all the doors - I have been stuck inside the car a couple of times where I needed to crawl out of the passenger side before I fixed the drivers door.

I went to the parking garage after work, and had difficult getting into my vehicle. The remote did not work. When I put the key in the lock, it would turn but not unlock the door. After about 15 minutes, I finally got into my car. I picked my sister up and went to the restaurant. I was unable to get out of the car. I tried the remote, the inside release and pulling on the lock. I finally got it to release. Then I had problems closing the door. We got it shut but when we came back from the restaurant it was open. I dropped my sister off and drove the mile home, the door again would not open nor would the passenger door open. I am claustrophobic and became very upset. I went back to my sister's and got the door open. We left it ajar, and when I got home it still would not open. After about another 15 minutes, I finally got it to release. Then next day when my husband took the car over to the dealers, he could not get the door to open. He was able to get the passenger door open and climbed out that way. I can understand the electronics malfunctioning, but not the manual system. I really feel this is a safety hazard. I just got off the chat line with General Motors and received no satisfaction or resolution. It was $300 to have the driver door lock actuator replaced/repaired. I still have no explanation as to why the manual system did not work..

The contact owns a 2006 Buick Lacrosse cxl (na). The contact attempted to unlock the vehicle to enter by using the key fob when he noticed that the door remained locked. Eventually, he was able to get in. He then drove about 100 feet and attempted to exit the vehicle and noticed that the both front driver and passenger side doors remained locked. The contact was forced to exit the vehicle by climbing into the back seat and exiting from the rear passenger door. Both the dealer and manufacturer were unable to duplicate the failure. However, they replaced the driver side mechanisms but did not have the parts to repair the passenger side and the contact was awaiting the parts to arrive. The current and failure mileages were 66,000. Updated 3/7/11 updated 04/22/11
