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 has updated the Panamera 4S for 2014 bringing a new long-wheelbase Executive model and a powerful twin-turbo V6 under the hood. We headed to Germany for a Quick Spin of the 2014 Porsche Panamera 4S Executive.
