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.

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 have more then one issue. First important issue. While driving down a state road with a peed limit of 50 at 50 mph. My car lost power check engine light came on and the warning light says engine reduced power all acceleration was lost was able to drive at about 30 and was close to a repair shop so got ther they diagnosed a throttle seal. Fixed and repaired December 30, 2016. 6/14/2017 while driving at 35 mph the same thing happened again. I have returned to the shop and discussed with gm service center they say no special notice about this issue but I see numerous complaints about the same issue in forums on line. Issue 2. The lights on the dash speed, warning info, radio light dim for no reason. Issue 3 door locks do not work from key fob or inside car have to work manually the passenger side air bag turns off even when some one in the seat. I have had this repaired once but continues to to this.

The left rear door lock does not lock or unlock unless done so manually. The door lock actuator does not work.

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 drivers 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 all 4 doors needed to have the actuators replaced. Priced over $1000. 00. They offered to pay $350. 00. 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 with, not only, this very expensive problem, but a severe safety issue.

Multiple times since purchase air bag indicator has either blinked, has been constantly on or hasn'¿¿t been on at all. Instrument panel display, mileage indicator, temperature display, trip indicator hasn'¿¿t worked on occasion, radio and/or interior temperature display doesn'¿¿t come on until you drive for five to forty five minutes. Door locks have actuated either up or down while driving. Remote door locks either don¿t work at all or one or more does, one or more doesn¿t work, when manually using a key security system has activated thus sounding the horn. Many of these items have been discussed with my dealer and we were told by them that gm is aware of the problem but there isn'¿¿t a fix at this time.
