Problems with 2007 Buick Lucerne EQUIPMENT

2007 buick lucerne. consumer writes in regards to rear view cameras and automatic headlights in all cars.. *smd

I own a 2007 buick lucerne. since i retired the car would sit in the garage for a few days whereupon it would go dead. i called onstar and had the car jump started but it kept happening. so the dealer finally took it in and tested the draw. they found a defective onstar module and another module connected to the door and lights that were bad. it has been fixed and so far so good until today when i was driving down the road and it just stopped dead. so i do not know the outcome of this failure yet. the only problem being it is now 2,000 miles out of warranty. *tr

Tl*the contact owns a 2007 buick lucerne. while attempting to change the front driver's side tire, the jack that was supporting the vehicle suddenly bent and split into pieces. the vehicle slammed down to the ground. there were no injuries. the vehicle has not been diagnosed by the dealer. the current and failure mileages were 11,500.

Bought car 6/2/08 with 6000 miles on odometer. immediately noticed extreme vibration throughout vehicle while driving also in park at 1500 rpms. dealer in consort with gm attempted to fix; could not do it. dealer alleges "vehicle working as designed". apparently designed to vibrate. my concern is that the problem is in the engine - not in suspension or tires, etc. with vibration comes inordinate wear and possible failure while driving possibly causing an accident with injuries. additionally, the front safety belts are defective in that they do not lock up and restrain the upper torso as designed. dealer has replaced both belts; however, they still do not work as designed and required posing a clear and present danger to the driver and passenger in the front seats. there has not been an incident as yet; however, the possibility of one is rather obvious and gm thus far has been unable to resolve the issue safely and satisfactorily. *tr
