NHTSA recall 04V071000
Power Train · Porsche Cars North America, Inc.
Details
What's wrong: Certain sport utility vehicles may have had a transfer case installed that could, due to changes in the housing casting, result in the oil pump rotation. Should this occur, oil starvation of the internal gears might result.
Why it matters: 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 fix: Dealers will inspect the transfer case housing and, if necessary, replace the transfer case. Owner notification began on May 3, 2004. Owners should contact Porsche at 1-800-545-8039.
