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. Until the door is repaired the backseat passenger sitting next to the frozen door cannot get out. I can't believe that the engineering team at gm has not discovered a fix for this condition. This is very disappointing and dangerous.

Unable to open rear passenger door. Tried from both inside and outside, tried manually unlocking and using remote to unlock. Door will not open. Afraid to use back seat now in case of emergency.

The back doors on my Buick Lucerne 2006 have not unlocked for over a month. Strangely, one day I leaned on one door from the inside and it unlocked for a few hours and then relocked. I see many other complaints for the same issue online. The dealers were not helpful or sympathetic and charged me one hundred dollars to diagnose this in five minutes, with a two grand estimate. It is unsafe for back seaters who cannot get in or out safely. This should be on a recall from gm right away.

When opening driver's door the handle came apart in my hand. I had my mechanic put it back together. This has happened twice so I am really afraid to open this door. Will Buick replace this door handle? updated ivoq 02/24/11.

The rear passenger and/or driver side door(s) will not open from the inside or the outside. It is as though the locking mechanisms are not engaging either door.

Door stoppers dont hold door in or on small incline causes door to close on leg or legs.

: the contact stated while the vehicle was placed in drive, the doors locked automatically. It was driven to the dealer who determined the door locks performed as designed.

The passengers will not be able to exit until the switch is operated or pulls up the manual lock post , then they can unlock the door by pulling the door handle. The consumer believes that takes too much time and effort if in an emergency situation. Updated 12/05/06.
