Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2003 Pontiac Grand Am Owner Comments

problem #1

Jul 272007

Grand Am 6-cyl

  • Automatic transmission
  • 24,691 miles


The contact owns a 2003 Pontiac Grand Am. When the contact took his vehicle to the dealer for routine maintenance on July 27, 2007, a technician informed him that the intake manifold gasket failed. The technician stated that the failure was caused by two different types of metal that were used on the head and intake manifolds. When heated, both metals expanded at different rates and caused the gasket to fail. The manufacturer admitted that the failure was directly related to a design defect. There is a remedy for the failure, but the contact would be responsible for the repair costs. An authorized dealer repaired the vehicle on May 5, 2008. The failure mileage was 24,691 and current mileage was 30,826. Updated 06/17/08.
