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.

The front headlights and running lights just go off for no reason. When driving home on night the headlights went off for no reason. The nest day, they worked. They continue to work, but the night they went out was very disturbing. The vehicle was in motion, on state hgwy, getting ready to turn to the right.

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.

Car is stationary. At approximately 50000 mi. (and 6 yrs of age) all four door locks started randomly and intermittently sticking. Symptom is that, once inside the car and doors are locked, doors will not unlock and handles do do not open the doors from the inside. Solution was to open the window and attempt to open from outside which sometimes worked. This is a safety issue. If there is an accident or passengers are otherwise in distress, cannot exit the car. Have seen repeated reports of this issue with this car. Should be investigated. Safety issue.

I submit this complaint on behalf of my senior citizen mother who is 75 years old. My mom had a very scary experience & got locked inside of her buick car for over 1/2 hour & could not unlock any of 4 car doors from inside to escape out of her car. Plus, key would not turn in ignition & car wheel locked up. It was winter season !! Car was stationery. All car windows were rolled up so my mom could not get any heat nor fresh air. My mom could have froze to death inside of her car !! More scary -- we have no idea when it can happen again nor how long the next lockout will last !! Clearly this is a safety issue !! Especially for a senior citizen person. We are amazed that buick did not yet issue a recall for this type of incident. I found buick forums on the internet where hundreds of other people complained of same related problems !! I emailed all 7 websites to bcr. Some people cannot even unlock driver car door to into get into driver's seat !! They have to enter their cars thru passenger & crawl over to passenger car seat or enter from backseat of the car !! Obviously buick & gm never did anything yet about this scary & annoying problem !! On march 16 2018 I opened a new case #8-4000469674 with buick customer relations (bcr). They flagged this as a safety issue !! Bcr said buick will only work with a buick car dealer on this issue if my mom brings her car to a buick car dealer. So we made an appt for this monday, april 16 8:30am at fox valley buick (fvb) in st. Charles, il to get her buick car diagnosed !! Bcr will work with fvb & cem (customer experience manager). Clearly -- this is a very serious safety issue !! In hot heat or winter cold -- a person can literally suffocate or freeze being a trapped prisoner inside of their car !!! 2 bcr reps failed to call me back over 4 days. One bcr rep was supervisor. But I was diligent & I followed up with bcr !!

I had driven to the store, when I tried to exit the vehicle the driver's door wouldn't open from the inside or outside. The driver's door lock actuator failed in a way that prevented the door from opening. I tried using the inner and outer handles, I also tried using the door lock switch and the manual lock nob. I had to exit the vehicle by crawling over the center console to use the passenger side door. I was finally able to open the driver's door the next day by rapidly locking and unlocking the door using the manual lock nob a good 30 times. The car is a four door and none of the automatic locks work. The car also has 99500 miles. The fact that all four locks have failed is one thing, it's the fact that they can leave you unable to use your door in case of an accident that is the major safety hazard. Fixing just the driver's door is costing me $525.00 at a local buick dealership. A quick google search revealed that this is a problem across all gm w-body cars from about 2006 to 2009.
