What 62 owners told NHTSA about the 2011 Porsche Cayenne E-hybrid Coupe

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 COOLANT PIPE DESIGN IS FLAWED. THE BARB IS GLUED AND PRESSED IN THE ALUMINUM BODY. OVER TIME THE GLUE LOSES ITS PROPERTIES AND THE BARB COMES OUT THUS CAUSING MASSIVE COOLANT LEAK AND THE ENGINE CAN OVERHEAT. THE PART WAS REDISGNED AROUND 2015 WHERE THE BARB IS NOW THREADED, BUT THE ORIGINAL PART IS A SAFEY HAZARD FOR THE OLDER MODELS WITH POTENTIAL HUGE REPAIR COSTS.

I WAS PULLING FORWARD ON A LEVEL CITY STREET AND TURNING LEFT FROM A STOP SIGN. THERE WAS A SIGNIFICANT AMOUNT OF SHUDDERING AND FEELING OF A LOSS OF POWER. THIS WAS A SIGNIFICANT SAFETY ISSUE DUE TO ONCOMING TRAFFIC. OVER A PERIOD OF SEVERAL MONTHS THIS HAD BEEN INCREASING IN SEVERITY BUT THE DEALER COULD NOT IDENTIFY THE PROBLEM. I TOOK IT TO THE DEALER AND WAS ABLE TO REPEAT THE PROBLEM FOR THEM. THEY IDENTIFIED THE TRANSFER CASE AS THE ISSUE. IT WAS REPLACED. I ALSO HAD TO REPLACE THE TIRES DUE TO THE DEALERS IDENTIFICATION THAT THE TRANSFER CASE HAD CAUSED DIFFERENTIAL TREAD WEAR DAMAGE TO A REAR TIRE. AS A FORMER MILITARY AVIATOR, THERE IS NO DOUBT IN MY MIND THAT THIS IS A SAFETY ISSUE. PORSCHE NEEDS TO IDENTIFY WHAT THE ISSUES ARE (DESIGN, MANUFACTURING, SERVICING, ETC) AND REMEDY THEM. SURPRISINGLY, THIS IS A KNOWN PROBLEM BECAUSE THE SERVICE ADVISER INFORMED ME THAT THEY KEEP TRANSFER CASES IN STOCK. THEY RETAIL FOR $3944, PLUS THE NEW VENT KIT (MINE DOES NOT HAVE IT) AND THEN ADD LABOR, AND TIRES IF THEY HAVE BEEN DAMAGED. THAT IS A LOT OF EXPENSIVE INVENTORY TO HAVE ON HAND IF PORSCHE WANTS TO CLAIM THERE IS NOT A PROBLEM.

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.

THE SCREWS HOLDING MY CAMSHAFT ACTUATOR FAILED AND I EXPERIENCED IMMEDIATE ENGINE LOSE AS WELL AS BRAKING LOSE DUE TO NO VACUUM. AT THE TIME OF MY ENGINE FAILURE IT WAS A KNOWN ISSUE FOR PORSCHE (SEE WC-22) WHEREAS THEY DID NOT MAKE PUBLIC AWARE OR PROACTIVELY FIX THE ISSUE. THIS ENDED UP COSTING ME APPROXIMATELY $7500 OUT OF POCKET (IN ADDITION TO SEVERAL EMOTIONAL DAMAGE DUE TO FINANCIAL CONSTRAINTS AND THE IMMEDIATE DANGER WHEN THE ENGINE FAILED AT HIGHWAY SPEED IN THE FAR LEFT LANE). PORSCHE HAS SUBSEQUENTLY ISSUED A RECALL (RECALL AH-08 AND NHTSA CAMPAIGN 17V368000) BUT HAD NOT CONTACTED AFFECTED OWNERS YET. I'D LIKE A FULL REFUND OF MY EXPENSES PLUS INTEREST. I ALSO FEEL THEY SHOULD BE FINED OR PAY IMPACTED OWNERS LIKE MYSELF A PENALTY DUE TO THEIR IMPROPER MISHANDLING.

VERY SCARY AND DANGEROUS EXPERIENCE ENGINE STALLED AFTER FILLING UP WITH GAS. THE VEHICLE REQUIRED TWO OR THREE ATTEMPTS TO START. I EXITED THE GAS STATION ONTO THE RAMP FOR THE INTERSTATE. THE CAR SUDDENLY LOCKED UP LESS THAN A MILE DOWN THE INTERSTATE WHILE DRIVING 70, MPH. THERE WAS NO POWER BRAKING OR POWER STEERING AT ALL. FORTUNATELY, I REMAINED IN THE FAR RIGHT LANE AND MOMENTUM CARRIED THE VEHICLE OFF THE NEXT EXIT RAMP BEFORE VEHICLE COMPLETELY SHUT OFF. I HAVE HAD A HOST OF OTHER ISSUES INCLUDING PSM FAILURES, START/STOP MODE DEACTIVATED ERRORS, IGNITION PROBLEMS, BRAKING ISSUES, UNNECESSARY REPAIRS, TIME/ENERGY, MISSED WORK, RENTAL CARS, MISDIAGNOSES, ETC. I AM CERTAIN THE SYMPTOMS ARE CONSISTENT WITH CAMSHAFT DEFECT AFFECTING MANY OTHER CAYENNE S, TURBO, AND PANAMERA S OWNERS PER SEVERAL INTERNET FORUM DISCUSSIONS. THIS IS REALLY DANGEROUS. I AM DISAPPOINTMENT EARLIER NOTIFICATIONS WERE NOT ISSUED AND I HOPE THIS MATTER IS ADDRESSED BEFORE SOMEONE DIES.

WHILE DRIVING THIS CAR ALL OF SUDDEN CHECK ENGINE LIGHT CAME ON AND ENGINE STARTED MAKING LOUD NOISES. CAR IS SHOWING VARIOUS FAULT CODES AND BRAKES STOPPED WORKING WHICH COUOLD HAVE CREATED MAJOR RISK TO DRIVER AND OTHER PEDENSTRIAN AND VEHICLES ON THE ROAD. ENGINE IS SHOWING VARIOUS MIS FIRE CODES AND CAME SHAFT RELATED CODES. IT IS TOO RISKY TO DRIVE THIS VEHICLE ON THE ROAD. VEHICLE HAS BEEN REGULARLY MAINTAINED BY PORSCHE DEALER AND IS UP TO DATE WITH ALL REQUIRED MAINTENANNCE. THIS IS VERY DANGEROUS PROBLEM AND MUST BE ATTENDED IMMEDIATELY AND DRIVERS OF THIS CAR NOTIFIED ASAP TO AVAOID ANY FATALITIES AND PROPERTY DAMAGE.

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.
