2011 Porsche Cayenne Turbo

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.

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.

PORSCHE HAS A KNOW DEFECT IN THE CAMSHAFT ADJUSTER SCREW FAILURE PORSCHE AS ALREADY LEAD A CAMPAIGN TO FIX THIS ISSUE IN OTHER PARTS OF THE GLOBE AND THIS FAILURE CAUSED MY VEHICLE TO HAVE CATASTROPHIC ENGINE FAILURE THAT PORSCHE NOW WANTS $35,199.00 TO FIX/REPAIR.

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.

MAJOR ENGINE FAILURE -RELATED TO DEFECT IDENTIFIED IN VOLUNTARY WORKSHOP CAMPAIGN WC-22-IN THE ALUMINUM CAMSHAFT ADJUSTER BOLTS WHICH HAVE A TENDENCY TO SHEER OFF, WHICH PREVENT THE CAMSHAFTS FROM RUNNING. IF THIS OCCURS IN THE CAMSHAFT THAT OPERATES THE VACUUM PUMP, THE POWER BRAKING WILL ALSO FAIL, WHICH WILL RESULT IN AN EXTREMELY DANGEROUS SITUATION ESPECIALLY IF THE DRIVER DOES NOT HAVE THE STRENGTH TO BRAKE THE CAR WITHOUT THE VACUUM POWDERED BRAKES. THE BOLTS THEMSELVES MAY ALSO DROP INTO THE ENGINE AND CAUSE THE ENGINE TO FAIL. IN MY CASE VEHICLE HAD DEALER ROUTINE SERVICE CHECK 3-4 DAYS EARLIER- EVERYTHING "PERFECT". ON DAY OF FAILURE STOPPED FOR GAS AND AFTER RESTART HEARD A NEW "TICKING" AND CHECK ENGINE LIGHT CAME ON. I CALLED DEALER WHO INSTRUCTED ME TO COME OVER. I DROVE ABOUT 3-4 MILES TO DEALER NEW PSM FAILURE AND ANOTHER I DID NOT GET WHEN CAR LOST POWER AND SEEMED TO BRAKE POORLY.. ROLLED INTO DEALER AND STILL THERE- ENGINE PULLED --MAY BE COMPLETE LOSS. DEALER ACKNOWLEDGED TODAY THIS IS THE SAME ISSUE AS WC-22
