At 80xxx miles the drivers front door lock actuator became inoperative. At 90xxx miles the passenger front door lock actuator became inoperative. At 96xxx miles the passenger rear door lock actuator became inoperative. Each runs $250-300 to repair. Not repairing leaves the door unlocked (while driving) or unlocked (while parked and vehicle becomes accessible to anyone) or the door remains locked when trying to exit or enter. In an emergency, this may cause problems. Searching the internet, there are many complaints about this on the lacrosse.

In january of 2015 the electronic door lock system began to malfunction. The remote first failed to control the right rear door. Then the malfunction spread to the left front door lock. The situation became worse until the entire locking system could only be controlled manually. Even then the physical key control frequently malfunctioned. Safety hazards were created including locking the keys inside an unoccupied running vehile, being totally unable to unlock the vehicle, and generally inconsistent ability too maintain control over the vehicles locking status. Approximately $1,000 dollars have been spent using genuine gmc parts to correct the problem. It is still unstable and in a deteriorated condition.

Multiple times since purchase air bag indicator has either blinked, has been constantly on or hasn't been on at all. Instrument panel display, ie: 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.
