Owners/service Manual Problems of Buick Lucerne

The doors, specifically rear doors, in this vehicle get stuck in an open or closed position. It appears to be a defect that causes the door latch to stay in the closed position, trapping children or other passengers in the back seat, or preventing the door from closing. From internet research, this is a common issue with the Lucerne (not just 2006) and the lacrosse. First we had the passenger rear door get stuck closed. After a month or so of unlocking and locking the doors, it started working again randomly, but a few months later, became stuck closed again with no trigger. We continued to use the driver's side rear door, but about a year later, it got stuck open. At first the door wouldn't open for my son, but I pulled on the handle from the outside while he pushed from the inside, and we got it open. When I tried to close the door, it bounced back. The latch is stuck in the closed position. The child safety lock is not engaged. The doors will not open from inside or outside the vehicle. The locks function normally manually, with the key fob, and by pressing the driver's button. The vehicle was parked and off during all incidences.

Suddenly the drivers side front door stopped unlocking. The door will not open because the locking mechanism continues to lock and unlocking quickly preventing you from opening the door. The door will not unlock manually, using inside lock button or by remote. This happens at anytime so you never know if you will be able to get out of the car. This is causing drivers to climb to the passenger side for exit preventing a quick exit in an emergency. Many many complaints have been filed for this safety issue and no recall on the mechanism that operates the doors leaving owners with a huge expense.

The rear passenger doors of the car do not open. The automatic door locks have failed to work. The mechanism design has failed because the manual door lock releases do not work. It is impossible to exit (or enter) the car from the backseat. The rear doors on both sides of the car do not open. There has been no accident and there has never been any prior damage. Since more than two people often ride in this vehicle, this is an extreme safety hazard because it is impossible to access the back seat of the car (especially in an emergency) unless reaching over the front seat from inside the car.
