Porsche Cars North America, Inc. (Porsche) is recalling certain model year 2013-2014 Cayenne and Cayenne GTS, model year 2013 Cayenne Diesel and model year 2014 Cayenne S, S Hybrid, Turbo, and Turbo S vehicles manufactured May 27, 2013, through July 10, 2013, according to the National Highway Traffic Safety Administration (NHTSA). In the affected vehicles, the calculated range of the remaining fuel displayed on the instrument cluster may be higher than the actual range. Additionally, the fuel level indicated by the fuel gauge may also be higher than actual amount in the tank.
The fuel display inaccuracies may result in the vehicle running out of fuel and stalling, increasing the risk of a crash.
Porsche will notify owners, and dealers will update the instrument cluster software free of charge. The recall is expected to begin in late November 2013. Owners may contact Porsche at 1-800-767-7243. Porsche's recall number is AD03.

In the affected vehicles, the passenger seats may be equipped with defective wiring harnesses resulting in intermittent contact with the harness plug.
The intermittent plug may cause the passenger seat frontal and knee airbags may be deactivated. In the event of a crash necessitating airbag deployment, this may increase the risk of injury to the front passenger.
Porsche will notify owners, and dealers will replace the front passenger seat free of charge. The recall is expected to begin in late November 2013. Owners may contact Porsche at 1-770-290-3500. Porsche's recall number is AD04
