2014 Porsche Cayenne Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Posche dashboard leather coming apart at the staples. I was informed that if involved in an accident the airbags might not deploy. The Porsche dealer inspected and recommended replacing it. This issue has been on going with Porsche since it first began within the first few years of owning this brand new vehicle. I was informed that this is a very common issue, and a very serious safety issue with no recall issued as of yet. Please help us

Dashboard leather has shrunk and removed staples. Dashboard leather is laying on top of airbag and may act as a deterrent to the airbag function. Was informed that the airbag may not deploy correctly. Cost to repair is >$10k due to a common material defect.

Catastrophic failure of Bosch CP4 high-pressure fuel pump in my 2014 Porsche Diesel Cayenne. Resulted in metal shavings/shrapnel throughout entire fuel system. Car abruptly stalled while pulling out of parking lot and was unable to restart. Had vehicle towed to nearest Porsche dealer for repairs. Quote for parts only (without labor) to repair vehicle is $29,440.47. With labor is in excess of $40,000. Car has been determined to be a total loss. My 2014 Porsche Diesel Cayenne has always been maintained at suggested intervals and all service work for the life of the car was performed by Porsche. It has been a wonderful, reliable and fun vehicle to drive prior to this horrible event. No warnings of fuel pump failure came up on vehicle warning and message system.

For the past nine years, my vehicle has recorded multiple safety issues (trunk not closing/breaking, check engine light, catalytic converter misfire, keyless electronic entry issues, glow bulb light, turn signal bulb light, windows not rolling up, leaking fluid on the passenger side, burning smell coming from the vents, electrical issues with the radio, sunroof intermittently not opening/closing and the key not turning the vehicle on. Over the past nine years, I have taken the vehicle to numerous Porsche dealerships per the federal mandate from Porsche USA / Porsche UK. To date, the Service Manager, Chris Sansbury and General Manager at Brian Harris Porsche, and Porsche USA, refuse to fix the vehicle. My vehicle is still under factory warranty. I am a person with multiple disabilities. The dealerships (Jim Ellis Porsche, Hennessy Porsche, Leith Porsche, Brian Harris Porsche) have charged me thousands of dollars. I have been extremely sick and desperately need your help. Please help me!

HUGE LAG WHEN PRESSING ON ACCELERATION PETAL WHEN PULLING OUT INTO TRAFFIC FROM A STOP. IT DOES NOT HAPPEN EVERY TIME. IT IS INTERMITTENT.

FRONT TIMING COVER HAS LARGE LEAK. VEHICLE HAS 88,000 KMS, ALWAYS REGULARLY SERVICED AT PORSCHE DEALERSHIP IN VANCOUVER. THIS IS A VERY COMMON ISSUE WITH PORSCHE V8 ENGINES AND REQUIRES A FIX IN THE AMOUNT OF APPROX. $5000-8000, AS THE ENGINE HAS TO BE TAKEN OUT OF VEHICLE. AS MY VEHICLE IS OUT OF WARRANTY, THIS COST IS PROHIBITIVE OUT OF POCKET, ESPECIALLY CONSIDERING THE VEHICLE IS RELATIVELY NEW WITH LOW KMS. PORSCHE SHOULD EITHER DO A RECALL FOR THESE ENGINES OR PROVIDE EXTENDED WARRANTY UP TO 10 YEARS FOR THE LEAKS, CONSIDERING IT IS WAY TOO COMMON. THERE ARE LOTS OF REPORTS IN RENNLIST, 6SPEEDONLINE AND OTHER NUMEROUS FORUMS REGARDING THIS.

Last week I took my car to car wash, After that my right passenger side light went off. water went in the rear sound control module and I lost sound too. my gps sound comes from woofer only. I heard from a by other Porsche owners that porsche had recall on rear lights, But I was never informed.

NHTSA ID 11614240 · filed Sep 12, 2024

After going through the car wash, I lost my rear brake lights and rear running lights. Still have the third brake light. From reading on many Porsche form sites, this is a common issue. The vehicle does not have adequate drains, in return, water leaks into multiple areas of the vehicle causing electrical shortages. You do not get any warning bells, or signs on the dash that you do not have rear taillights. It is a very dangerous issue.

SAME DAY I BOTH CAR WHEN I REACHED HOME... THE RIGHT SIDE TURN SIGNAL LIGHT FELL OFF AND WAS HANGING FROM THE WIRE. I HAD TO GO BACK TO THE DEALERSHIP TWICE TO FIX THIS PROBLEM BECAUSE THEY DIDN'T HAVE ANYTHING IN STOCK. AFTER 200 MILES ON MY CAR I STARTED TO HEAR A KNOCKING SOUND BETWEEN CONSOLE PANEL AND ENGINE, WHEN I WENT TO THE DEALER FIRST TIME THEY TRIED TO CONVINCE ME THAT IT?S NORMAL BECAUSE THERE IS SIMILAR SOUNDS FROM SOME OF OTHER CARS THEY HAVE IN STOCK. THEY DIDN'T SHOW ME ANY OTHER CARS THAT HAS THIS SOUND WHEN I WAS THERE. THEY STATED THAT ON THEIR REPORT THAT THEY DO NOT KNOW WHAT THE SOUND IS, BUT IT IS ON OTHER CARS AS WELL. I TOLD THEM THAT THE SAME MODEL CAR I TEST DROVE, DID NOT HAVE THIS SOUND, WHY WOULD THE SAME CAR HAVE SUCH A NOISE. THERE WAS NO ANSWER OR RESPONSE TO THIS QUESTION. THEY JUST STATED THAT THEY DON?T KNOW WHAT THIS. I CHECKED 2 OTHER CARS MYSELF AT THE SAME DEALERSHIP, ONE OF WHICH, THE TECHNICIAN WAS PRESENT FROM SAME DEALERSHIP. HE SAID THAT THE CAR WE CHECKED DOESN'T HAVE ANY NOISE, BUT MY CAR DOES. SERVICE DEPARTMENT MANAGER TOLD ME TO DRIVE AROUND TO HEAR IF NOISE GETS LOUDER THEN COME BACK TO DEALERSHIP. THE KNOCKING SOUND ON AND OFF, GOT PROGRESSIVELY LOUDER. I WENT BACK TO THE DEALERSHIP 3 TIMES WITH THE SAME PROBLEM BUT THEY STILL DIDN'T KNOW WHAT WAS CAUSING THIS AND DIDN'T WANT TO DO ANYTHING ABOUT IT. MY CAR ALSO HAVE A PROBLEM WITH THE SECURITY ALARM SYSTEM, IT GOES OFF AT ANY TIME OF DAY OR NIGHT AND THEY DID NOT TRY TO RECTIFY OR RESOLVE THE ISSUE. I ALSO NOTICED FROM BEING AT THE DEALERSHIP, THAT THERE'S ALSO A PROBLEM WITH SECURITY SYSTEM ALARM ON MANY OF THE CARS. WHEELS PAINT CONSTANTLY PEELING OFF. *TR

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
