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.

Initial incident happened while driving on a street. Door locks power cycled lock/unlock and then the car would cut off. No warning, no time to move to out of traffic or turn on hazzard. I use this vehicle to commute to and from work/childcare etc. I also travel of the freeway alot. That was the previous incident. The most recent incident occurred when the car would not turn over and upon doing research we found that it may be related to. Relay issue due to the fuze box being underneath the rear seat. Gm claims that because a bracket used to fasten the seat in place interferes with the fuze box and presses down on the fuze pump relay and causes it to burn out. After switching out the relays with the suggested lower profile relay, the car drove for a few hours and then when we parked we couldn't remove the key from the ignition. Upon lifting the back seat to disconnect the battery we smelled and heard the fuel pump relay burning and sizzling. Since the car was "serviced" by a buick dealer in june I'm assuming that it wasn't actually serviced the relay was just replaced and maybe a few other tweaks here and there but the issue was not resolved. I am very concerned about the reliability of this car. I have children that ride in the back seat. I am fearful that the car will catch fire or spark.

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.

Automatic door locks on various doors have failed repeatedly. This problem has required entire replacement of the door lock/latch assembly's which is quite expensive. Failure of door locks is sometimes not immediately noticeable since it is intermittent at first, until it does not work at all. Children or persons could fall out of car as result of failed locks that you think are locked but they are not. You rely on the door locks to keep everyone safe from accidentally opening the doors.

I own a 2009 buick lucerne that I attempted to start the vehicle on random occassions. On another occasion the vehicle stalled on highway 49 in the middle of traffic. It fails to start, some relays are hot even when the car is off, fuel relay has been replace 4 times and it gets extra hot and will almost burn your hand, the fuse box is melted partly and has a burning smell. The fuel pump voltage was checked and is good. On the last try to crack now the driver door windo and door lock is not working. There is no corrison under the fuse box. Buick does not have a recall out on the fuse box or relay. The vehicle had to be towed 25 miles. This is a safety hazard. I have a disabled daughter who is transported in my car and I worry about the safety of this vehicle. Buick is aware of this issue with this particular car. The bucik forum and the federal safety agency websites both have complaints about this issue. The manufacture has been notified. It will take accidents, injury, or deaths for this issue to be resovled it seems. As buick and dealers continue to sell these cars many peoples lives are I jeopardy. I have reviewed pages on complaints and again buick is aware of these issues.
