Porsche Panamera TSBs
The Panamera has been assigned 252 technical service bulletins (TSB). The 2017 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 Porsche to service technicians. You'll often see TSBs used as evidence in lawsuits when owners feel the automaker should help with repairs.
