Selected complaints filed with NHTSA by 2000 Buick Lesabre owners, lightly cleaned up (personal details are redacted by NHTSA).
As I was driving my Buick Lesabre 2000 my windows lock up on me it was a very hot summer so the electrical windows with no go up and down. The engine is bad. 1490000 miles. Electrical system is problems. The car wiring is loose and can be a dangerous. I tried to pull window down and repair its manually frozen with no power. My seat are uncomfortable with hard iron wire.
Tl* the contact owns a 2000 Buick Lesabre. The contact stated that the vehicle was taken to an independent mechanic due to a flat tire. The contact was informed the inner tie rod bushing had rusted and needed to be replaced. The vehicle was not diagnosed nor repaired. A dealer was not contacted. The manufacturer had not been informed of failure. The failure mileage was 93,000.
While driving the vehicles tread separated from the right rear tire which caused the vehicle to veer into a guard rail. Other problems are as followed: drivers side and rear windows are inoperative, cruise control switch is inoperative and after it rains there is a water puddle on the driver side floor.
The upper dashboard has separated from the car as it is raised from the left corner to the middle of the dashboard, at the front of the dashboard closest to the windshield. In some places it is over 6 inches raised. It continues to worsen, moving over to the right side of the dash closer to the passenger airbag. I am concerned that this might cause the passenger airbag to go off by mistake. It has also reached the height where driver frontal vision is beginning to be slightly impaired because of this defect. I am aware that this is an inherent problem with these dashboards in this model vehicle. I have contacted GM and they have offered no assistance. This vehicle has been garaged and not out in the sun more than usual.
The dash pad started peeling up, from the windshield side directly in front of the driver, approximately 2007. Every year it curled up more & more, by 2013 it had lifted about 3". I contacted Buick around 2010 about this defect, they did nothing. After researching this defect I have found hundreds of other Buick owner have had this same issue. This curling defect can particularly block one's field of view, especially short drivers who May not even be aware the dash is curling up.
Auto battery acid leak which has eaten a hole in floor of car in passenger compartment. Battery is located in passenger compartment under rear seat. Acid leaked from damaged battery post over period of time. Due to location of battery it is only checked when car fails to start due to battery failure. Hole in floor permits car exhaust gases to enter passenger compartment. Updated 01/09/08. Updated 12/12/07
Dash pad cover material has separated from the dash pad base. Issue is seen on many 2000-2005 Buick Lesabre automobiles. Manufacturing defect that needs a senior brand manager to step up to the plate for a solution to the high number of dissatisfied owners like me. I also have a 2002 Lesabre custom that is doing the exact same thing. I will file a complaint on that unit as well.

Four days later, the contact took her vehicle to a mechanic and it was discovered that the undercarriage was rusting and corroding. The mechanic stated that parts of the undercarriage May be damaged. The VIN was unknown. The current and failure mileages were 52,456.
Dashboard cover lifting at driver side sight-line approximately at 1 o'clock position (straight ahead is 12 o'clock) over about a one foot width, where dashboard meets windshield . Height of rise maybe only an inch now but getting worse. Headliner also falling from overhead blocking driver's rearward view through rear view mirror.
When the car was purchased there were no dashpad flaws. Car was and still is garage kept. The dashpad has been lifting across the entire width of the pad from front to rear and exposing the structure underneath. This includes the passenger side airbag area which the dash pad is completly lifted and not sure if airbag is exposed.
