Door locks somtimes would lock or unlock and other times not work at all. Made it a issue when parking or entering the car. I had to replace the lock mechanism in the doors. The car has 99135 miles on it but should not have a problem especally the back doors since they are not used very often.

What owners say
While driving, the engine shuts down and restarts. At the same time, all four door locks unlock and lock. In most cases, the issue happens once and does not reappear for that trip. The worst can have it do this at least three times. Once, I did notice an alert message appears on my console that disappeared as soon as it happened. This instances appear not to be as bad, since I had the battery replaced (Shortly after this issue appeared, the battery went from being a "good" battery, to a dead one. Nevertheless, these issues do happen on a periodic basis.
Doors will not lock with either the fob or the interior lock button on either doors. I'm reading on line of similar issues with this model where doors will not unlock!
Tl* the contact owns a 2005 buick lacrosse. The contact stated that the doors failed to open from inside the vehicle. The contact was locked inside the vehicle for an hour. The contact stated that the electrical system allowed other components to function including the windshield wipers, the heater, and the door locks. The contact researched and was concerned that the system was hacked. The vehicle occasionally failed to start or turn over. The engine was previously replaced at the contact's expense. The contact was once locked inside the vehicle and almost suffered from heat exhaustion. The contact stated he was disabled. Jeff key motors (2889 us highway 431, anniston, al 36206, (256) 820-0280) was unable to provide a cause for the failure after a month of diagnosing the vehicle while the vehicle was in their custody.

The air bag light comes on frequently, but mainly during hot summer days and has came on several times since we purchased the vehicle march of 2019. The light comes on when we are stationary and while driving. When doing research, this seems to be a common problem with other consumers vehicles. I had read it was an electrical issue and in my opinion this is very dangerous and should be a recall. Another issue we have that I also seen was a common issue with lacrosse owners, is the power locks. None of my lock work properly, all of them have to be manually locked and unlocked. Today, december 10, 2019, we noticed that when I tried getting out of the car the door would not open. Door was unlocked and had been unlocked. My boyfriend tried opening the door from the outside and it would not open. I tried to lock it and unlock it again, I tried pushing the door really hard to see if it would pop open and no luck. I think there should be a lot more recalls on this vehicle as I've had this issues as well as many others.
I just purchased this car last week and I noticed when I hit the lock on the fob, my alarm would sound, but my door looks wouldn't close. So I tried it in my car as well with the locks on the door and nothing. The unlock works perfect by the way (fob & door locks). I manually lock my doors at night and in the morning, the locks will work a few times, and then stop again. Also the doors do not lock when you take the care out of park.
First issue car will shut off driving down the freeway doing 60 70 miles an hour it will just shut off and I have to coast to the side and wait and wait till it starts again very dangerous. Next issue is the airbag light flashes on and off I'm assuming do I do to a pressure sensor in the passenger seat which I have a daughter that sits in the passenger seat and I don't know if the airbag is working or not. Next problem are the door locks they lock they don't lock the left rear does not work I have to manually pull it up and push it down if I want it locked the key fob warning is always on my dash saying key fob battery is low I replaced it I replace the key fob itself it just works when it wants to. Next problem the check engine light comes on goes off comes on goes off and therefore I cannot use my remote start if the check engine light is on it has been checked there's nothing wrong with the car nothing shows up if you check the gauges I don't know what to do I paid a lot of money for my remote start cannot use it and I'm in minnesota. I need my car fixed it's reliable it's a good car it's what I drive it's my car I have a daughter's life at stake in my car I expect it to be trusted in the car that I bought after reading all the complaints on the site regarding the same issues that my car is having I am hoping literally hoping that your company is willing to fix these issues in my car and all the other people that are waiting in line cuz this is ridiculous
The power door locks do not work properly even when using the interior switches. Most of the time, doors must be locked or unlocked manually ! Our 2008 buick lacrosse cxl has less than 51,000 miles and should not have this problem. This is a very serious safety issue because I've read that people were trapped/ unable to get out of their lacrosse when trip was done.
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.
