NHTSA Complaint #10956246 — 2011 PORSCHE CAYENNE TURBO

LATE 2010 TO EARLY 2012 PORSCHE CAYENNE VEHICLES WITH V8 ENGINES HAVE A MANUFACTURING DEFECT WITH BOLTS THAT HOLD THE CAMSHAFT ADJUSTERS. THE WEAK BOLTS IN QUESTION ARE MADE OF ALUMINUM AND HAVE BEEN EXPERIENCING FAILURES WHERE THEY SHEER OFF, CAUSING CATASTROPHIC DAMAGE TO THE ENGINE. IF THIS FAILURE OCCURS WHEN THE VEHICLE IS AT SPEED, A LOSS OF POWER BRAKING AND STEERING WILL OCCUR AS A RESULT. PORSCHE IS AWARE OF THE PROBLEM AND WAS FORCED TO RECALL ALL THE AFFECTED VEHICLES IN CHINA BY THE CHINESE GOVERNMENT, BUT HAS SO FAR AVOIDED RECALLING THE AFFECTED VEHICLES IN THE US. THE NECESSARY REPAIRS INVOLVE REPLACING THE DEFECTIVE BOLTS WITH STEEL ONES. PORSCHE NO LONGER USES THE DEFECTIVE BOLTS IN THEIR V8 ENGINES BUILT AFTER 2012. I BELIEVE PORSCHE WILL NOT ADDRESS THIS DEFECT PROPERLY IN US CARS UNLESS AN INVESTIGATION IS LAUNCHED WITH THE POSSIBILITY OF A RECALL. REPAIR COSTS PER VEHICLE ARE ESTIMATED AT $3500, COMPARED TO $30,000 FOR THE COST OF A COMPLETE REPLACEMENT ENGINE. THERE ARE NUMEROUS WEBSITES WITH USERS EXPLAINING THE PROBLEM AND LIMITED REMEDIES. HERE ARE JUST A COUPLE: HTTP://TINYURL.COM/Z929BFN HTTP://TINYURL.COM/JOU52BS MY VEHICLE HAS THE DEFECTIVE BOLTS IN QUESTION BUT PORSCHE HAS SAID THEY WILL NOT CORRECT THE PROBLEM AND FEEL MY CAR IS NOT AT ISSUE. I FEEL IT IS ONLY A MATTER OF TIME BEFORE MY ENGINE EXPERIENCES THIS FAILURE. MY ONLY OPTIONS ARE TO EITHER MAKE THE REPAIRS AT MY COST, HOPING TO ONE DAY BE REIMBURSED, OR TO SELL THE VEHICLE. I AM HOPING BY FILING THIS INCIDENT INFORMATION, PORSCHE CAN BE PERSUADED TO CORRECT THEIR DEFECT IN THE THOUSANDS OF VEHICLES SOLD IN THE US. THANK YOU.
