CONTINUED OPERATION OF THE VEHICLE COULD RESULT IN A FRACTURE OF THE TRANSFER CASE HOUSING. INCORRECT TORQUE WOULD THEN BE APPLIED TO THE DRIVEN WHEELS OR OIL COULD LEAK AND CONTACT THE TIRES.
The transfer case may have a design flaw that starves internal components of oil and causes the housing to fracture. Dealers will inspect the transfer case housing and replace transfer cases found to be defective free of charge to resolve the concern.
Porsche notified owners of affected vehicles starting in May 2004. You can check with your dealer to see if your vehicle is involved in this program. It is helpful to have your VIN (Vehicle Identification Number) on hand when you contact them.
