NHTSA Complaint #11269753 — 2013 PORSCHE CAYENNE

PURCHASED A 2013 CAYENNE PORSCHE GTS WITH 67K MILES ON IT. NOTICED A KIND OF THUMPING SOUND WHEN ACCELERATING, USUALLY APPEARING AT 3K RPMS. VEHICLE SHUDDERS AND ALMOST FEELS LIKE THE TRANSMISSION IS SLIPPING. TOOK THE VEHICLE TO A MECHANIC TO DIAGNOSE THE FAULT AND THEY IMMEDIATELY KNEW WHAT IT WAS, ENGINE TRANSFER CASE FAILURE. THIS IS DUE TO A DESIGN FLAW ALLOWING WATER INTO THE TRANSFER CASE THAT PORSCHE IS AWARE OF AND YET TO ADDRESS. ON SOME OCCASIONS PORSCHE WILL PAY FOR THE $5K REPAIR BUT THE PART IS STILL REPLACED WITH A TRANSFER CASE WITH THE SAME FLAW. TRANSFER CASE FAILURE CAN LEAD TO A SUDDEN LOSE OF POWER AND POTENTIALLY CAUSE DEATH OR SERIOUS INJURY IF SOMEONE IS TRAVELING AT HIGHWAY SPEEDS. HIGHLY RECOMMEND ADDRESSING THIS WITH A RECALL FOR 2013 AND 2014 CAYENNES. I HAVE EXPERIENCED SUDDEN LOSE OF POWER DUE TO TRANSFER CASE FAILURE, NEATLY RESULTING IN A HIGHWAY COLLISION.
