Open the full vehicle complaint log (all categories)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!
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.
THE DASHBOARD LIGHTS ALL TURNS ON AND MESSAGE COMES UP INDICATING TO RESTART THE VEHICLE TO START. THIS HAPPENS WHEN THE CAR IS IN PARK GEAR TO UNLOAD SOMEONE AND WITHIN 2 MINS - 5 MINS THE ENGINE WILL STOP AND THE ABOVE MESSAGE APPEARS
TL* THE CONTACT OWNS A 2014 PORSCHE CAYENNE. THE CONTACT STATED THAT THERE WAS A SEPARATION BETWEEN THE BUMPER AND HEADLIGHTS. AS A RESULT, WATER ENTERED THE HEADLIGHT ASSEMBLIES AND CAUSED ELECTRICAL FAILURES. THE CONTACT STATED THAT THE HEADLAMP BULBS NEEDED TO BE REPLACED ON SEVERAL OCCASIONS. THE CONTACT ALSO STATED THAT THERE WAS EVIDENCE OF WATER DRAINING FROM UNDER THE DASHBOARD ONTO THE FLOORBOARD. ADDITIONALLY, THERE WAS A BURNING ODOR ON THE INSIDE AND THE OUTSIDE OF THE VEHICLE. THE CONTACT STATED THAT THE BURNING ODOR WAS MORE PREVALENT AFTER THE CATALYTIC CONVERTER WAS REPLACED PER A CLASS ACTION LAWSUIT. THE VEHICLE WAS TAKEN TO HENNESSEY PORSCHE (990 MANSELL RD, ROSWELL, GA 30076, (770) 643-6100) AND PORSCHE ATLANTA PERIMETER (4006 CARVER DR, ATLANTA, GA 30360, (888) 893-6299), BUT THE FAILURES COULD NOT BE DUPLICATED.

THE CONTACT REQUESTED THE TIRES BE PLUGGLED, BUT THE DEALERSHIP DECIDED TO DO OTHERWISE.
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
