2011 Porsche Cayenne Turbo Recalls & Complaints

Incident: June 16, 2024 · Filed: August 23, 2024

The contact owns a 2011 Porsche Cayenne Turbo. The contact stated that while starting the vehicle, the vehicle shuddered abnormally. Additionally, while driving, the vehicle experienced a loss of power steering assist, and the brake pedal was firm while depressed. The vehicle failed to come to a complete stop. The traction control, check engine, oil pressure, and several other unknown warning lights were illuminated. The vehicle was towed to the dealer, where it was diagnosed that the passenger's side camshaft controller and bolts had failed. The dealer determined that both the driver's and passenger's side camshaft controllers and bolts needed to be replaced. The dealer replaced the camshaft adjusters and bolts under NHTSA Campaign Number: 17V368000 (Engine) associated with the VIN; however, the contact was not satisfied with the remedy for the recall. The contact stated that the dealer failed to recover all the failed bolts inside the engine. The manufacturer was made aware of the failure and a case was opened. The failure mileage was 131,046.

TRANSFER CASE FAILURE. THERE IS AN ACKNOWLEDGMENT BY PORSCHE OF AN ASSOCIATED DEFECT OF THE TRANSFER CASE DESIGN AND A RELATED WORKSHOP BULLETIN (WB) WHEN REPLACING THE TRANSFER CASE. PORSCHE MECHANICS ARE INSTRUCTED TO REPLACE A "VENT HOSE" FOR THE TRANSFER CASE. THIS NEWLY REVISED DESIGN PART NUMBER FOR THE REVISED VENT IS 958-301-047-10. THE REASON: THE ORIGINAL DESIGN FOR CAYENNE 958 PORSCHE TRANSFER CASES HAD THE HOSE ENDING ON THE LOWER (CLOSER TO THE GROUND) SIDE OF THE TRANSFER CASE. THE NEW HOSE ENDS ON THE UPPER (FURTHER FROM THE GROUND) SIDE OF THE TRANSFER CASE. PORSCHE DETERMINED THAT MOISTURE WAS GETTING SUCKED INTO THE CASES AND CAUSING FLUID CONTAMINATION. SINCE THE TRANSFER CASE USES A "MULTIPLATE WET CLUTCH", MOISTURE COULD PREMATURELY CORRODE OR ALLOW RUST TO FORM, WHICH COULD CAUSE THE CLUTCH TO BIND AND WORK ERRATICALLY. THESE ARE SYMPTOMS DESCRIBED BY MULTIPLE OWNERS OF 958 CAYENNES DISCUSSED IN PORSCHE FORUMS (E.G. RENNTECH.ORG, RENNSLIST.COM, ETC.). THIS REVISED VENT DEVELOPED BY PORSCHE TO REPLACE THE EXISTING DESIGN, SHOULD BE COVERED BY PORSCHE. MOREOVER, OWNERS OF 958 CAYENNES WHO HAVE EXPERIENCED FAILURES OF THE TRANSFER CASE AND SUBSEQUENT REPLACEMENT OF THE TRANSFER CASE AND THE NEWLY DESIGNED HOSE, SHOULD BE REIMBURSED FOR THE FULL COST OF THE REPLACEMENT TRANSFER CASE AND THE HOSE. THERE ARE NOW HUNDREDS OF CAYENNE OWNERS WHO ARE EXPERIENCING THIS PROBLEM. MOREOVER, THE MAINTENANCE SCHEDULE DOES NOT CALL FOR ANY PREVENTATIVE FLUID CHANGES OF THE TRANSMISSION OIL. THIS SHOULD BE REVISED AND RECOMMENDED SERVICING SHOULD BE PRESCRIBED (E.G., EVERY 10,000 MILES). THE FAILURE OF THE TRANSFER CASE COULD CAUSE VEHICLES TO LURCH OR REACT IN AN ERRATIC OR UNSAFE CAPACITY ACROSS THE SPECTRUM OF OPERATION, INCLUDING HIGHWAY SPEED DRIVING. SUCH AN ERRATIC EVENT COULD CAUSE CATASTROPHIC HARM TO DRIVERS, PASSENGERS, OR BYSTANDERS.

DRIVING ON HIGHWAY WHEN THE CAR DRAMATICALLY LOST POWER AND STALLED, LUCKILY I WAS CLOSE TO AN EXIT AND MANAGED TO GET OFF THE HIGHWAY. HOWEVER THERE WAS AN 18 WHEELER BEHIND ME THAT HAD TO BRAKE HARD TO AVOID HITTING ME. I GOT TO THE BOTTOM OF THE EXIT RAMP AND THE CAR WAS BARELY RUNNING. WAS ABLE TO GET IT BACK TO THE DEALER (WHICH WAS ONLY 1/4 MILE AWAY) THE PROBLEM WAS THE CAMSHAFT ADJUST BOLTS ON BANK #1 SHEARED. THIS IS A KNOWN DEFECTIVE PART AND PROBLEM WITH ALL PORSCHE V8 ENGINES FROM 2011-2012.

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.

CAMSHAFT ADJUSTER BOLTS STARTING TO BECOME LOOSE AND BACK OUT, WHICH IS A KNOWN MANUFACTURING DEFECT ON THOSE CARS, CAN LEAD TO SUDDEN UNPREDICTABLE LOSS OF STEERING AND BRAKING, AND POTENTIALLY ACCIDENTS, ESPECIALLY WITH VERY HEAVY AND VERY FAST CAR LIKE THIS ONE. DEALER QUOTED $4000 TO FIX WITH NEW BOLTS AND ADJUSTERS. ATTACHED ARE PICTURES TAKEN WITH A BORESCOPE FROM MY ENGINE. I AM SCARED TO DRIVE IT. THIS SHOULD BE A RECALL. OWNERS SHOULD NOT BE PAYING FOR THIS. ALSO ATTACHED IS QUOTE FROM DEALER.
