What 53 owners told NHTSA about the 2014 Porsche Cayenne Coupe S

WHEN ACCELERATING FROM A STOP GEARS SEEMS TO BE MISSING AND JUMPY BETWEEN 2-5 GEARS, LIKE SHUDDERS ON GEARS. I READ THAT IT'S COMMON PROBLEM WITH CAYENNE. THIS NEEDS TO BE ADDRESSED BY PORSCHE AS IT IS VERY COSTLY. VEHICLE ONLY HAVE 21,000 MILES.

WHILE ACCELERATING TRANSMISSION SHIFTING FROM 2 TO 5 GEAR, IT SHUDDERS AND POWER LURCHES. SAME WHILE MAKING TURN AT STOP SIGN FROM STOP TO ACCELERATE AT CITY STREET POWER LURCHES. POSSIBLE TO CAUSE T BONE ACCIDENT. HIGH CHANCES OF COMPLETE POWER LOSS DUE TO TRANSMISSION FAILURE DUE TO FAULTY TRANFER CASE RESULTING IN CATASTROPHIC ACCIDENT. ASK PORSCHE TO REPLACE TRANFER CASE WITH NEW DESIGNED TRANFER CASE.

HUGE LAG WHEN PRESSING ON ACCELERATION PETAL WHEN PULLING OUT INTO TRAFFIC FROM A STOP. IT DOES NOT HAPPEN EVERY TIME. IT IS INTERMITTENT. IT SEEMS TO HAPPEN MORE FREQUENTLY WHEN YOU ARE TURNING RIGHT. IT DOES NOT MATTER IF YOU PUSH THE ACCELERATOR DOWN , , OR CLEAR TO THE FLOOR, WHEN IT HAPPENS YOU HAVE NO POWER FOR A COUPLE OF SECONDS. NEVER HAD THIS PROBLEM BEFORE THE GOVERNMENT MANDATE RECALL FOR EMISSIONS. THE OTHER ISSUE AFTER THE EMISSION RECALL IS THE VEHICLE ACC/PAS SYSTEM WILL ERROR OUT WHEN CRUISE ENGAGED AND THE VEHICLE NEEDS TO ACCELERATE FOR AN INCLINE IN THE ROAD. THERE HAS BEEN COUPLE OF TIMES ALSO; REAR-ENDED ANOTHER VEHICLE BECAUSE OF ACC/PAS FAILURE.

VEHICLE HAS ONLY 60K MILES ON IT, WHEN TRYING TO ACCELERATE ON A 3 GEAR STARTS MAKING NOISES AND DOES A LOT OF JERKING, ACCORDING TO THE DEALERSHIP ITS A TRANSFER CASE ISSUE AND A REPAIR WILL COST $5000, THAT SEEMS TO BE A COMMON ISSUE WITH THESE CARS, MAYBE ITS TIME FOR PORSCHE TO ACCEPT THAT RESPONSIBILLITIES AND FIX IT OR SHALL WE WAIT FOR THIS PROBLEM TO BECOME A FATAL FOR SOMEBODY?

FUEL GAUGE INACCURACY. FUEL GAUGE DANCING THEN SHOWS FUEL GAUGE FAULT.

WHILE DRIVING ON THE CITY STREET FOR ABOUT 10 MINUTES WHEN A MESSAGE "FAULT-FUEL GAUGE" POPPED UP ON MY INSTRUMENT CLUSTER. TRIED TO FILL THE TANK AT THE GAS STATION BUT THEN THE TANK WAS FULL HOWEVER THE FUEL GAUGE INCORRECTLY INDICATING THE TANK IS ONLY 1/2 FULL.MESSAGE WOULD INTERMITTENTLY COME ON WHILE DRIVING. THIS VEHICLE WAS MANUFACTURED IN JUNE 2014 NOT RECALLED NOR CORRECTED BY PORSCHE MANUFACTURER IN THEIR RECALL OF 2014 MODEL. CAR MILEAGE IS ONLY 39,563 AND THIS CARS VIN WAS NOT INCLUDED ON PORSCHE RECALLS. THIS PARTICULAR FAULT IS EXACTLY THE SAME FAULT AS ALL THE 2014 CAYENNE PORSCHE HAS PREVIOUSLY RECALLED.CARFAX REPORT ON THIS MODEL/VIN STATES NO RECALL. IT WOULD BE DANGEROUS TO TAKE THIS VEHICLE FOR A LONG DRIVE DUE TO INACCURACY IN FUEL GAUGE READING AS VEHICLE CAN DANGEROUSLY RUN OUT OF FUEL AND STALLING AND INCREASING RISK OF ACCIDENT.

FAILURE OF TRANSFER CASE IN TRANSMISSION AT 74000 MILES. THIS IS A WELL DESCRIBED PROBLEM AND THERE ARE HUNDREDS OF SIMILAR COMPLAINTS ON THE INTERNET IN PORSCHE CAYENNES. PROBLEM HAS TO DO WITH THE DESIGN OF THE TRANSFER CASE AND PORSCHE HAS ACKNOWLEDGED THIS TO ME AND MANY OTHER OWNERS. AS A RESULT OF THE PROBLEM THE VEHICLE CAN LURCH FORWARD AND ALSO FAIL TO ACCELERATE CAUSING SAFETY ISSUES. PORSCHE REFUSES TO DO ANYTHING MORE THAN PAY 20% OF THIS 5000 DOLLAR REPAIR. I URGE THE NHTSA TO INITIATE A FORMAL INVESTIGATION OF THIS PROBLEM AND FORCE PORSCHE CARS OF NORTH AMERICA TO INITIATE A RECALL CAMPAIGN FOR THE SAFETY OF THE PUBLIC AND FOR THE THOUSANDS OF OWNERS LIKE MYSELF WHO HAVE SPENT 70000 TO 90000 ON A PREMIUM SUV AND ARE LEFT HELPLESS. THANK YOU FOR YOUR ASSISTANCE.

PORSCHE DIESEL EMISSION COMPLIANT FIX: - PORSCHE WAS REQUIRED TO APPLY EMISSION FIX TO 2014 CAYENNE DIESEL - DIESEL EMISSION SETTLEMENT REQUIREMENT IS THE EMISSION FIX "..WILL NOT RESULT IN ANY NOTICEABLE CHANGES TO THE DRIVING CHARACTERISTICS.." - IN JAN 2018, EMISSION FIX WAS APPLIED TO 2014 CAYENNE DIESEL - RIGHT AFTER FIX, THE CAR SHOWED 2-3 SEC LAG FROM THE STOP. AT STOP, WHEN GAS PEDAL IS PRESSED, THE CAR DOES NOT ACCELERATE FOR 2-3 SEC, THEN IT "JUMPS" - IN MAY, CAR WAS TAKEN TO PORSCHE DEALERSHIP. DEALER STATED THAT THIS LAG IS NORMAL AFTER FIX, EVEN THOUGH THERE WAS NO SUCH LAG BEFORE FIX - PORSCHE DEALERSHIP INSTALLED LATEST SOFTWARE ON THE CAR IN MAY. AFTER THAT, LAG DECREASED FROM 2-3SEC TO 2 SEC. BUT THE CAR STILL HAS ABNORMAL LAG - IT FEELS UNSAFE TO DRIVE THE CAR, WHEN MERGING TO ROUNDABOUTS, WHEN MERGING FROM THE STOP - A COMPLAINT WAS FILED WITH PORSCHE CARS OF AMERICA. REQUIREMENT OF NO "... NOTICEABLE CHANGES TO THE DRIVING CHARACTERISTICS" WAS DISCUSSED. PORSCHE SAID THAT THE PERFORMANCE IS "AS DESIGNED" - CLEARLY, WHEN CAR WAS PURCHASED IN 2014, THERE WAS NO LAG. THAT'S WHEN THE CAR PERFORMED AS DESIGNED. - EMISSION FIX NOTICEABLY CHANGED CAR DRIVING CHARACTERISTICS, IT MADE THE CAR FEEL UNSAFE. PRESSING GAS PEDAL FROM STOP DOES NOT RESULT IN SMOOTH POWER DELIVERY, IT IS NOT CLEAR IF THE CAR WILL DRIVE OR NOT FOR 2 SEC

WHILE ADAPTIVE CRUISE CONTROL IS ENGAGED THE VEHICLE WILL BRAKE ON ITS OWN. THIS OCCURS WHEN THERE ARE NO OTHER VEHICLES OR OBJECTS IN SIGHT. THE VEHICLE APPLIES THE BRAKES HARD ENOUGH WHERE IF ANOTHER CAR IS FOLLOWING CLOSELY IT COULD REAR-END MY VEHICLE. I HAVE HAD THE CAR IN TO CIRCLE PORSCHE 5-6 TIMES WITH NO RESOLVE. THIS WAS FIRST REPORTED TO THE DEALER ON JUNE 29, 2015.

CAR RATTLES AND SHAKES SIGNIFICANTLY (ESPECIALLY THE REAR WHEELS) DURING ACCELERATION. TOOK THE CAR TO DEALER INFORMED ME THAT IT IS THE 'TRANSFER BOX' THAT HAS FAILED AND IT IS A KNOWN PROBLEM WITH THIS CAR. THE ISSUE IS SO COMMON THAT PORSCHE DOES NOT HAVE PARTS AVAILABLE AND THEY ARE ON BACK ORDER. THE WAIT FOR THE PARTS TO ARRIVE COULD BE IN MONTHS. THIS SHOULD BE A RECALL.

ON MULTIPLE OCCASIONS WE ARE NOT ABLE TO REMOVE THE ELECTRONIC KEY FROM THE IGNITION WHEN THE TRANSMISSION SELECTOR IS PLACED IN THE PARK POSITION. THIS HAS HAPPENED APPROXIMATELY 20 TIMES IN THE LAST SIX MONTHS ON THE STREET IN PARKING LOTS AND AT HOME. I HAVE VIDEO OF THE FAILURE.

I PURCHASED A 2014 PORSCHE CAYENNE DIESEL NEW IN AUGUST 2014 EQUIPPED WITH THE CONVENIENCE PACKAGE WHICH INCLUDES BI XENON HEADLIGHTS WITH "PORSCHE DYNAMIC LIGHTING SYSTEM" (PDLS). THE PDLS IS QUITE COMPLICATED AND HAS SOME GOOD FEATURES BUT IT DOES NOT ILLUMINATE DOWN THE ROAD VERY FAR AND IS DANGEROUS ON HILLY TERRAIN. SOMETHING IN THE SYSTEM MAKES THE TOP OF THE BEAM SHUT OFF SHARPLY SO IF YOU APPROACH A HILL YOU CAN NOT SEE BEYOND THE BASE OF THE HILL. EVEN REFLECTIVE SURFACES ARE NOT ILLUMINATED. I DO A LOT OF DRIVING ON HILLY TERRAIN WITH A LOT OF WILDLIFE. THIS IS A DANGEROUS SITUATION. I HAVE WRITTEN THIS UP ON EACH OF 4 VISITS TO THE PORSCHE DEALER AND THEY SAY UNTIL PORSCHE COMES UP WITH A FIX, THERE IS NOTHING THEY CAN DO. PORSCHE REFUSES TO DO ANYTHING ABOUT IT.

ON 11/19/2015 AT APPROX 7:20AM WHILE DRIVING THE PANORAMIC SUNROOF EMPLODED ON IT'S OWN, NOTHING HIT IT FROM THE OUTSIDE OR INSIDE. THERE WERE NO CARS AROUND ME ON THE ROAD NOR WAS THERE ANY VISIBLE SOUND OF ANYTHING HITTING US IT WAS JUST A LOUD BOOM AS THE SUNROOF SHATTERED IN AN UPWARD PATTERN AS IF IT WERE UNDER PRESSURE, ALSO CAUSING DAMAGE TO THE PAINT/BODY ON ROOF OF CAR FROM THE GLASS DEBRIS. DEALERSHIP REFUSING WARRANTY BECAUSE THEY DO NOT KNOW WHAT CAUSED IT.

I WAS EXITING THE HIGHWAY INTO A REST AREA, AND AT ABOUT 30-35MPH THE CAR'S ENGINE SUDDENLY CUT OUT. ALL THE DASHBOARD WARNING LIGHTS LIT UP, THE POWER STEERING FAILED, AND EVEN WITH THE BRAKE TO THE FLOOR THE CAR WOULD BARELY SLOW DOWN. I PUT THE CAR IN PARK AND RESTARTED IT AND IT DROVE NORMALLY. I'M NOW AFRAID TO DRIVE MY BRAND NEW CAR, BECAUSE IF THE ENGINE CUTS OUT IN THE MIDDLE OF AN INTERSECTION OR TURNING LEFT AGAINST TRAFFIC, I COULD BE INVOLVED IN A VERY SERIOUS CRASH. THIS IS MORE THAN JUST AN INCONVENIENCE, IT IS A VERY SERIOUS SAFETY FLAW! IF I WAS MAKING A LEFT TURN AGAINST TRAFFIC AND MY TWO YEAR OLD NIECE WAS IN HER CAR SEAT IN BACK, SHE WOULD BE DIRECTLY IMPACTED BY THE VEHICLE DUE TO THE FACT THAT THE CAR DECIDED TO STOP WORKING! *TR
