2006 Buick Lucerne: doors won't lock, open or latch

Filed Jan 16, 2021 · Body · 172,997 miles · SC

Front passenger door latch has come loose multiple times while in the vehicle. It temporarily fixes itself, then randomly occurs again. Door will not open from the inside or outside. This is definitely a hazard in an accident. This isn't the first lucerne that I've driven with this problem and it's quite common. There is no safety lock on the door for this to keep happening.

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.

The door locks don't operate as it was designed due to a binding lock rod grommet preventing the lock rod from actuating the lock. This was not due to any accident nor was the car traveling to initiate this problem.

Door does not open using either inner or outer door handle. I have seen many people complain about this issue on line. Buick has had this problem on multiple cars for multiple years. Safety issue big time when one cannot get out of the car quickly because door won't open. There are only 2 people in my family and thus the rear doors are very seldom used. Did not break from overuse, design problem.

Vehicle has numerous issues over the years. 80k miles currently, tires leak air because of corrosion on the rims, this is my 2nd set of tires not counting the set the vehicle came with, breaks have been done twice, rotors have been replaced, both front door handles have come off, problems with the leveler, now door locks lock/unlock while driving but not just once (might happen 6-8 times). Local dealer & service station have performed repairs/replacements. Already been under 2 recalls.

On may 13, 2016 I went to open the driver's side front door. The car was stationary. To my utter surprise, the handle came completely off! On may 25, I took it to reichard, dealership. Since the car has only 54, 589 miles on it I asked the dealer for assistance in paying to fix it. He refused, saying "we get a lot of these. The manufacturer used plastic instead of metal and the plastic breaks." I asked the advisor to call general motors. She did and reported back to me that gm would not do anything. One of the advisors told me that I can expect the other three door handles to break as well. Since the car only has 54k miles, how could that happen? I have three other cars and only drive the lucerne a few times a year, mainly on out-of-town trips. Therefore, I have driven the car only about 5,500 miles per year. I consider this a defect in the design and manufacturing of this vehicle. This defect will cost me about $1,000. But most importantly, it could be a safety hazard if/when a I need to to enter the car and when someone has to be quickly extracted from the car! Also, a few friends and complete strangers who own buick lucernes have told me that I can expect to have transmission problems with this car. Have you had complaints with the transmissions?

Driver door handle breaks just like the door handle on the cadillac. Why was cadillac recalled but not buick? Let's be fair both are gm cars. Clearly a defect according to service dept. There are so many.

Rear passenger door will not open from inside or outside when handles are activated. It will unlock with fob and stem at door but is stuck shut. Appears to be locked all the time. Would be unsafe if one was in a emergency situation. It happen when I stopped and was trying to exit. It happen on a highway during a stop on shoulder.

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.
