Driver's side door will not unlock and will not open. It will not unlock with the lock button or with the key. I have to climb over the passenger seat to enter and exit the vehicle. I looked the problem up online and found that many people have complained about this. It is a safety concern since I will not be able to get out of the car in an accident.

I purchased this vehicle a year ago with 66,100 miles. One previous owner. The passenger side rear door would not open. It's still inoperable. I do not know when the door stopped working, just that it was prior to 66,100 miles. It has made the vehicle un-safe to exit from the rear seat when parked street-side.

Trapped inside of 2006 lacrosse with a door lock that would not open. Dealer could not replicate the problem nor fix it. Gm executive offices claim the door lock is a wear item. It is unacceptable for a door lock to trap a person inside a car that has 83,000 miles and 9 years old. Enough such occurrences are discussed on various sites on the internet. This combined with a faulty passenger seat airbag sensor and executive managament's lack of concern is enough to stay away from all gm products.

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..
