Pontiac Grand Prix TSBs
The Grand Prix has been assigned 1,120 technical service bulletins (TSB). The 2008 model year has been involved in the most bulletins.
TSBs contain recommended steps and procedures for diagnosing or repairing a known problem. They are issued directly by Pontiac to service technicians. You'll often see TSBs used as evidence in lawsuits when owners feel the automaker should help with repairs.
