What 44 owners told NHTSA about the 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.

My vehicle has camshaft and crankshaft correlation problems due to the well-known problem with its screws and other things. I reported it to Porsche and they told me that it has already been repaired but I don't understand how to fail again and deny help for its repair.

THE ALUMINUM BOLTS ON THE TIMING COVER ARE BROKEN CAUSING AN OIL LEAK. IF THE ALL BOLTS ARE MADE OF ALUMINUM THEN WHAT ABOUT THE TRANSFER CASE? I'VE HEARD ABOUT NEAR ACCIDENTS BECAUSE OF BOLTS BREAKING EITHER BECAUSE OF THE MATERIAL DIFFERENCE BETWEEN THE BOLTS AND THE MAGNESIUM IN THE MOTOR. IT HAS OCCURRED ON OTHER MODELS OF PORSCHES. PORSCHE SHOULD RECALL AND FIX THE ALUMINUM BOLTS ON ALL PARTS.

COOLANT LEAKS WHILE VEHICLE IS STATIONARY. LEAK IS DUE TO FAULTY PLASTIC THAT WAS REDESIGNED TO METAL TUBING DUE TO COMMON REPORTED ISSUES. PLASTIC TUBING CONNECTED TO COOLANT SYSTEM WILL BECOME BRITTLE AND CRACKED, CAUSING OVERHEATING AND LOST OF COOLANT. THIS ISSUE IS COMMONLY REPORTED ABOUT THE 2011 CAYANNE WITH A DEALERSHIP COST OF UP TO $4500.

THE BOLTS ON THE CAMSHAFT CONTROLLER BROKE INSIDE OF MY ENGINE. WHEN THIS HAPPENED, I WAS DRIVING SOUTHBOUND ON THE 405 FREEWAY IN LOS ANGELES, CA. THE CAR VIOLENTLY JERKED AND THEN STALLED ON THE FREEWAY. THIS ALMOST CAUSED A MAJOR ACCIDENT, BUT THANKFULLY EVERYONE WAS ABLE TO AVOID MY CAR. I'VE BEEN TOLD BY A FEW REPAIR SHOPS THAT THE DAMAGE DONE BY THE LOOSE BOLTS LIKELY DAMAGED THE ENGINES INTERNAL COMPONENTS AND I WILL LIKELY BE NEEDING A NEW ENGINE OR AN OVERHAUL OF THE EXISTING ENGINE.

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.

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

THE CAR STOPPED WHILE BEING DRIVEN IN TRAFFIC ON A BUSY SUBURBAN ROAD. THE CAR WOULD NOT RESTART. RIGHT BEFORE THE CAR SUDDENLY STOPPED THE PSM LIGHT CAME ON. THIS WAS THE ONLY THING THAT OCCURRED PRIOR TO THE SUDDEN STOP. THE CAR WAS PUSHED OUT OF THE ROAD AND FLAT BEDDED TO PAUL MILLER PORSCHE IN PARSIPPANY, N.J. THE SERVICE TECHNICIAN(S) FOUND THAT AT LEAST ONE ALUMINUM BOLT FROM THE CAM SHAFT ADJUSTER HAD SHEARED OFF AND FELL THROUGH THE ENGINE CAUSING COMPLETE ENGINE FAILURE. THE ONLY WAY TO REPAIR THE CAR WAS TO REPLACE THE ENGINE. THE CAR WAS PURCHASE BRAND NEW ON JUNE 15, 2011. THE CAR HAD BEEN SPECIAL ORDERED SEVERAL MONTHS PRIOR TO THE DELIVERY DATE. AFTER THIS INCIDENT, I RESEARCHED THIS ISSUE. IT APPEARS THAT PORSCHE CAYENNES AND PANAMERAS MANUFACTURED DURING THE SAME TIME PERIOD OUR CAR WAS MADE WERE RECALLED IN CHINA FOR THIS EXACT SAME ISSUE-ALUMINUM CAMSHAFT ADJUSTER BOLTS SHEARING OFF INTO THE ENGINE AND CAUSING TOTAL ENGINE FAILURE. THIS CAR WAS OUT OF THE PORSCHE 4 YEAR/50K WARRANTY PERIOD. I NOTIFIED PORSCHE NORTH AMERICA OF THIS INCIDENT AND THEY REFUSED TO REPLACE THE ENGINE. THE CAR WAS COVERED UNDER OUR GEICO MECHANICAL BREAKDOWN INSURANCE. GEICO SENT OUT INSPECTORS TO EXAMINE THE CAR AND DEEMED IT A TOTAL LOSS. WE SURRENDERED THE CAR TO GEICO AND WERE PAID WHAT THEY DEEMED THE CAR WAS WORTH. THE LAST TIME WE SAW THE CAR WAS AT PAUL MILLER PORSCHE IN PARSIPANNY, N.J. ON JULY 26TH WHEN WE EMPTIED IT OF OUR PERSONAL BELONGINGS. LUCKILY NO ONE WAS HURT IN THIS INCIDENT. OBVIOUSLY A CAR SUDDENLY STOPPING WHILE BEING DRIVEN IS HUGE DANGER. HAD THIS OCCURRED ON A HIGHWAY OR IN FASTER TRAFFIC THE RESULTS COULD HAVE BEEN CATASTROPHIC.

THERE HAVE BEEN INCREASING REPORTS OF VARIOCAM CAMSHAFT DRIVE BOLT FAILURES ON THE 2011 PORSCHE CAYENNE V8 ENGINES. WHEN THESE BOLTS FAIL, ENGINE DAMAGE OCCURS, AND THE ENGINE TYPICALLY STOPS RUNNING. IN THE CASE OF THE TURBO MODEL - THIS CAN ALSO RESULT IN THE LOSS OF BRAKING ABILITY SINCE THE BRAKES ARE POWERED OFF A CAMSHAFT. THERE IS ALSO A LOSS OF POWER STEERING - MEANING YOU HAVE A 4,500LB VEHICLE WITHOUT BRAKES OR STEERING. PORSCHE HAD A LIMITED "WORKSHOP CAMPAIGN" FOR THESE VEHICLES THAT ADDRESSED A CERTAIN RANGE OF VIN# IN THE USA. IT IS WC-22 (I'M ATTACHING A PDF OF IT.) THE FAILURES ARE NOW BEING REPORTED WITH INCREASING FREQUENCY IN VIN#'S NOT COVERED BY THIS WORKSHOP CAMPAIGN. THE CAMPAIGN INVOLVES REPLACING THE VARIOCAM ASSEMBLY WITH ONE ASSEMBLED WITH STEEL BOLTS RATHER THAN ALUMINUM BOLTS. EARLIER VERSIONS OF THIS ASSEMBLY ALSO USED STEEL BOLTS, AND THE FAILURES APPEAR LIMITED TO ONES WHERE THE ALUMINUM BOLTS WERE USED. THE MOST COMPLETE DISCUSSION ON THIS CAN BE FOUND AT: HTTP://WWW.6SPEEDONLINE.COM/FORUMS/CAYENNE/319690-SNAPPED-CAMSHAFT-ADJUSTER-BOLT-ENGINE-BRAKE-HYDRAULICS-FAILURE.HTML THERE ARE OTHER WEBSITES AND DISCUSSIONS ON THE SAME FAILURE. HERE IS AN ARTICLE ON THE RECALL PORSCHE DID IN CHINA FOR THE SAME PROBLEM: HTTP://EUROPE.AUTONEWS.COM/ARTICLE/20150209/ANE/150209861/PORSCHE-WILL-RECALL-SOME-PANAMERA-CAYENNE-MODELS-IN-CHINA MINE HAS NOT FAILED YET - BUT IT APPEARS TO BE JUST A MATTER OF TIME, MINE HAS THE ALUMINUM BOLTS IN THE ASSEMBLY. I WOULD ASK THAT PORSCHE EXTEND THE WORKSHOP CAMPAIGN TO ALL THE VEHICLES WITH THE ALUMINUM BOLTS USED IN THE VARIOCAM ASSEMBLY. THE FAILURE OF BOTH BRAKES AND STEERING THAT OCCURS WHEN THESE BOLTS FAIL IS AN OBVIOUS SAFETY ISSUE WITH THESE VEHICLES. IT MAKES ME HESITANT TO DRIVE THE VEHICLE. I'VE ASKED THE LOCAL DEALER ABOUT IT, AND THEY CLAIM MY VEHICLE IS NOT EFFECTED.
