IF THE SHAFT FRACTURES, OIL MAY BE DRAWN INTO THE EXHAUST SYSTEM, RESULTING IN SMOKE AND THE INCREASED RISK OF A FIRE.
The turbocharger turbine wheel may fracture due to a casting defect. If a fracture occurs, vehicle performance will be decreased and the turbine shaft may also fracture. If the shaft fractures, oil can be drawn into the exhaust system, resulting in excessive smoke and the risk of a fire. Dealers will replace the turbine wheels to correct this concern. The Porsche recall number is AC04.
Porsche will notify owners of affected vehicles during July, 2012. If you notice excess smoke from the exhaust, or you don't receive notification and you feel you should have, please contact your dealer. It’s helpful to have your vehicle identification number (VIN) handy when you call.
