2006 Pontiac Montana Owner Comments

problem #2

Oct 032010


  • 80,000 miles


The contact owns a 2006 Pontiac Montana. While driving 55 mph there was a thumping sound and a screeching noise causing the vehicle fish tail. The vehicle was driven onto the side of the road where he noticed that the tire was leaning into the wheel well and the right rear ball joints were broken. The vehicle was towed to the dealer who replaced the ball joints and the tire. He had to pay for the repairs since there was no warranty or recall. The failure occurred previously on the left rear tire where the ball joint was broken. The manufacturer was not notified. The VIN was unavailable. The failure mileage was 80,000 and the current mileage was 86,000.

problem #1

Montana 6-cyl Diesel

  • Automatic transmission
  • 9,000 miles
2006 Pontiac Montana van, 9,000 miles, rear stabilizer snapped completely in half while under normal driving conditions. No encountered with road debris, pot holes or other outside influences caused this problem. A loud noised was heard by the driver and she felt the rear end wobble. She pulled the van to a stop. The rear wheel and "axle" became "free floating and detached from the frame" causing the tire to roll backwards into the wheel well and the stabilizer to fall to the ground. Fortunately, this happened in parking lot while moving less than 5 mph, and not at a highway speed. The dealer who is conducting the warranty work stated that he had never seen this problem, but would report it to GM and also noted that no other area under the car had any damage, indicating that it appeared to be strictly a failed structure. The "stabilizer had apparently just snapped", he stated. The van had never been involved in any accidents and was purchase new from a certified GM dealer. The whole rear end, axle, brake lines, stabilizer and other related parts have to be replaced.
