LaCrosse 6-cyl

  • 60,000 miles
From approx. 60,000 miles drivers door would stick in the locked position regardless of lock solenoid actuation. Cycling door lock solenoid several to "many" times usually loosened it up, however, at 80,000 miles it stuck for 3 days. Dealer that replaced the mechanism advised that when the door unlocks, there is a metal gear in the door lock mechanism that engages a plastic gear that moves to engage the door handles (in & out) so when you pull on either handle the door opens. So, when the plastic gear wears out, your done. Dealer had to break into the car because the door will not open with this malfunction. Drivers door, passenger door and now, last week at 180,000 miles the rear driver side door have all malfunctioned and needed replacement. Approx. $250 - $300 each time depending on need to break in. Safety issue if you get locked in when it malfunctions.

problem #2

On a cold morning in February, outside driver's side door handle broke off during normal opening function. Upon further investigation, it turns out that the entire handle is merely chrome-plated plastic, with pem nuts inserted into the rear side of the handle. The entire tensile load of the handle is carried on these two points, and this is where the plastic fractured. Having no luck finding replacement parts, and no reason to believe that putting a similarly-designed handle would prevent the problem from recurring, I repaired the handle by drilling through the handle and putting 2 bolts and 2 nuts through the body of the handle to secure it to the door.

The contact owns a 2005 Buick Lacrosse. It was made known to the contact that there were no child locks on the doors in his vehicle. Through research, he discovered that the 2004, 2006, and 2007 Lacrosse models were equipped with child restraint locks. He felt that it was a safety concern that his year was not included. The dealer stated that they would have to go through the manufacturer to reach a resolution. The contact spoke with someone from the safety division of the manufacturer, who stated that they would get back in touch with him. There had been no failure to date. The current mileage was approximately 11,000. Updated 4/23/09 updated 04/27/09.
