This is a problem known well enough to Buick that they have published a service bulletin ... 06-07-30-026 that illustrates the problem. If Buick has knowledge that this is happening to so many vehicles that it comes out with a service bulletin for it, they should issue a recall and pay for the known problem to be corrected. It is a problem that immobilizes the car so it is not simply an irritant, it is a week ruining event.

my 2006 Buick Lucerne, has been becoming the worst car that I have ever owned.the plastic piece under the front bumper hits the driveway when backing out to the street.i had to screw it to the bumper,the back doors wouldn't unlock.had a warranty at the time.they fixed them both thankfully.had to replace the windshield washer pump.and now the shift lever won't come out of park.all the time.what the heck is with the so called best car on the market.gag.*&%$#@+|/"'?/..
