2006 Buick Lucerne Latches, locks and linkages Problems

“Door locks jam and can't open door. Locks can not be manually opened. Locked in vehicle. Reported 8/21/08 and fixed. 2/16/10 broke and I had to pay $400. 6/25/13 broke 3rd time and GM refused to refund me $400 and said vehicle had too much mileage. I was told to buy a new car. Numerous reports of faulty locks on internet.”

“I closed the rear driver's side door. I then locked the car. Later after unlocking the vehicle the door would not open; from the outside or inside. It appears to be locking and unlocking. After checking forums I see that there are many Buick Lucerne owners that have also experienced this issue. This is a major safety issue! I can't believe there isn't a recall on this car. I'm scared to put my children in the back seat by chance we are in a accident and they are injured.”

“Latches locks linkages -- starting at 52000 miles, my Buick Lucerne 2006's rear passenger door would not open under any circumstances. The door will not open from the inside, from the outside, and although the key fob visibly actuates the latch, it does not assist in opening the door. Now at 53000, the driver's side rear door will not open. I now have no access to half of the inside of the automobile. After investigating numerous complaints on the internet, I discovered that apparently this is due to a latch assembly failure in each door. …”

“2006 Buick Lucerne - vehicle rear doors will not open from inside or out. Doors are unlocked but passengers in the back seat can not exit the car without climbing over the front seat to exit the front doors. Car doors will not open with inside door handle or outside door handle. Requires replacement of the rear door lock assembly.”

“The rear door locks on the 2006 Buick Lucerne have a fundamental design flaw. If the rear seat passenger pulls the door handle to open the door while the door is locked, and holds it in place when the power lock mechanism attempts to unlock the door, the mechanism binds internally making the door impossible to open. This has occurred 5 times on our Lucerne over the past 4 years. The only way to open the door is remove the inner door panel. Reach into the lock through the access holes and free up the mechanism. …”
