2006 Buick LaCrosse Owner Comments

problem #5

May 012016


  • 100,000 miles


The contact owns a 2006 Buick Lacrosse. While driving 30 mph, the front driver side wheel began to make an abnormal noise. The vehicle was taken to an independent mechanic who diagnosed that the lug nuts and the control arm needed to be replaced. The vehicle was repaired; however, the failure recurred. In addition, while at a stop and attempting to make a left turn, another vehicle crashed into the rear of the contact's vehicle. The air bags failed to deploy. The ABS and electronic stability control warning indicators illuminated. The contact sustained back, right arm, and right leg injuries that required medical attention. A police report was filed. The vehicle was towed to an auto body repair center for body repairs, but was not diagnosed or repaired for the failure. After the vehicle was repaired for the crash, the gear shifter was shifted into the drive position and the vehicle began to roll backwards. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The contact was aware of NHTSA campaign numbers: 06V417000 (air bags) and 14V355000 (electrical system). The failure mileage was 100,000. The VIN was unavailable.

The shift linkage tube crosses over the fuel line at the top of the engine. When shifting out of park, the tube moves. The movement of this tube is abrading the the insulation on this fuel line.

While turning corners, car jerks forward and wheels seemingly stick to ground and squeal. This also happens when stopping at red lights and trying to accelerate or when accelerating when on a hill or incline. I've have gotten several different answers about what this could be but nothing definitive. Was told make a transmission issue, or something to do with the 4th clutch piston and friction plates. Also when driving car is able to be moved into different gears, gear box should not move when car has already been placed into the appropriate gear (P, R, D, 3, 2, 1). There has also been issues w/ those sitting in the passenger seat and the light does not display showing that it recognizes a body in the seat and the airbag has been activated. Checked w/ GM no known recalls for any of this issues but they are all potentially hazardous.

On my 2006 Buick Lacrosse, at about 48K miles there was a loud clicking noise from under the hood.....luckily I was still under warranty because it was a cracked flywheel (flex plate)......I go on my happy way and about 10 months later I have the same problem....and since I am over the mileage portion of the part warranty, GM refused to cover it 100%......ok, I realize its technically out of warranty, but there is nothing that I can do to that car to cause the flywheel to crack...something is making this happen and GM refuses to refund me. I spent hours and hours on the phone with GM....
