A potentially defective turbine wheel in the turbochargers of 2011 and 2012 Porsche Panamera Turbo and Turbo S models and the 2012 Porsche Cayenne Turbo has led to a recall. There are 270 units affected among the three models, with a casting defect being cited as the cause of the trouble. The issue could lead to a fracture in the turbocharger itself, which could then lead to follow-on problems, smoke and risk of fire.
Porsche is notifying owners this month, after whcih they can take their cars to their dealers for repair free of charge. A complete notice from the National Highway Traffic Safety Administration is below..
