2005 Pontiac Montana recalls

5 NHTSA recall campaigns list this model year.

  1. NHTSA 10V110000Mar 19, 2010Suspension, Wheels & Tires5,375 vehicles

    Suspension:rear

    The braun corporation has notified NHTSA about a defect in certain model year 2005-2008 general motors mobility conversion, handicapped accessible low floor minivans. During conversion, the driver or passenger side trailing arm modification may not have been adequately welded.

    Risk: A squeaking or clunking noise may develop. The trailing arm bushings may prematurely wear and the trailing arm may fracture or separate, allowing the rear axle to become partially separated from the chassis increasing the risk of a crash.

    Remedy: Dealers will inspect and will have a supply of retrofit parts available to remedy the vehicles free of charge. The safety recall began on june 4, 2010. Owners may contact braun at 1-800-488-0359.

  2. NHTSA 06V417000Oct 31, 2006Airbags794 vehicles

    Air bags:frontal

    Certain vehicles originally built with cloth seats that were equipped with an automatic air bag passenger sensing system and later reupholstered with aftermarket leather seat cover kits are involved. Testing has indicated that the aftermarket leather seat covers can cause the passenger sensing system to malfunction.

    Risk: If the passenger sensing system malfunctions, the front air bag on the passenger side may be disabled when it should be enabled, or enabled when it should be disabled. In either case, in the event of a crash that requires air bag deployment, a front passenger's level of injury may be increased.

    Remedy: Because a replacement leather seat cover that is compatible with the passenger sensing system is not available, general motors (gm) will repurchase these vehicles in accordance with the terms stated in gm's letter to owners. The recall began on november 6, 2006. Owners should contact gm at 1-877-477-1022 to begin the process of repurchasing their vehicle.

  3. NHTSA 05V287000Jun 20, 2005Brakes14,600 vehicles

    Parking brake

    Certain sport utility vehicles fail to conform to the requirements of federal motor vehicle safety standard no. 135, 'passenger car brake systems.' to meet the standard, the vehicle must not move for five minutes when stopped on a steep hill with the parking brake applied and the vehicle in neutral (n). Some of these vehicles failed this test.

    Risk: When the parking brake is released, the driver may notice unintended braking when accelerating, decelerating, or coasting, and a noise coming from the rear of the vehicle. Unintended vehicle movement could occur increasing the risk of a crash.

    Remedy: Dealers will inspect for parking brake lever slippage at each rear brake caliper and replace the caliper if lever slippage is identified. The recall began on november 14, 2005. Owners may contact buick at 1-866-608-8080, chevrolet at 1-800-630-2438, pontiac at 1-800-620-7668, or saturn at 1-800-972-8876.
