2013 Porsche Cayenne

This vehicle qualified for the Volkswagen Emissions Recall, yet from the start of the recall through 2018 settlement lawsuit dates , no correspondence was sent (by Porsche nor VW). According to all recall regulations, my vehicle should have among the ‘recall’ with the 85K plus others, yet no correspondence was sent (by Porsche nor VW) & now the local Porsche dealership is denying in, According to all recall regulations, even still with the EPA, the vehicle was to receive an initial emissions test, then undergo all related repairs/part replacements before the issue resulted in toxic emissions, NOX sensor failures, & premature problems with the DPF system, leading to thermostat problems & the failure of the diesel turbo. Federal regs mandate that vehicle & vehicle equipment manufacturers comply with Early Warning Reporting requirements, submit to NHTSA copies of their manufacturer communications. & update all communications including warranty, policy extensions & product improvement communication sent to dealers, distributors, owners, purchasers, etc. regarding any defect, failure or malfunction beyond normal deterioration in use, failure of performance, flaw or other unintended deviation from design specifications whether it is safety-related or not. Porsche now says my vehicle never showed the recall, despite court mandates that all affected vehicles will be notified communication failed on the sides of both manufacturers. In 2026, if one possesses an eligible vehicle but never received a "Dieselgate" recall notice, options for financial compensation from the original U.S. settlements stated to be likely limited, & I’m not able to find how to proceed with Volkswagen, but regardless, according to EPA and all vehicle standards, I read my vehicle is still entitled to receive an emissions modification at no cost, and that I should be covered by an extended emissions warranty to address all current & related issues.

PURCHASED A 2013 CAYENNE PORSCHE GTS WITH 67K MILES ON IT. NOTICED A KIND OF THUMPING SOUND WHEN ACCELERATING, USUALLY APPEARING AT 3K RPMS. VEHICLE SHUDDERS AND ALMOST FEELS LIKE THE TRANSMISSION IS SLIPPING. TOOK THE VEHICLE TO A MECHANIC TO DIAGNOSE THE FAULT AND THEY IMMEDIATELY KNEW WHAT IT WAS, ENGINE TRANSFER CASE FAILURE. THIS IS DUE TO A DESIGN FLAW ALLOWING WATER INTO THE TRANSFER CASE THAT PORSCHE IS AWARE OF AND YET TO ADDRESS. ON SOME OCCASIONS PORSCHE WILL PAY FOR THE $5K REPAIR BUT THE PART IS STILL REPLACED WITH A TRANSFER CASE WITH THE SAME FLAW. TRANSFER CASE FAILURE CAN LEAD TO A SUDDEN LOSE OF POWER AND POTENTIALLY CAUSE DEATH OR SERIOUS INJURY IF SOMEONE IS TRAVELING AT HIGHWAY SPEEDS. HIGHLY RECOMMEND ADDRESSING THIS WITH A RECALL FOR 2013 AND 2014 CAYENNES. I HAVE EXPERIENCED SUDDEN LOSE OF POWER DUE TO TRANSFER CASE FAILURE, NEATLY RESULTING IN A HIGHWAY COLLISION.

WHEN ACCELERATING THE VEHICLE SPUTTERS AND CATCHES. THIS IS EXTREMELY DANGEROUS IF TRYING TO ACCELERATE ON A HIGHWAY OR SHOULD YOU NEED TO ACCELERATE TO AVOID A COLLISION. MY VEHICLE WAS BOUGHT BRAND NEW AND CURRENTLY ONLY HAS 23,600 MILES ON IT. THIS SHOULD NOT HAPPEN TO A CAR WITH VERY LOW MILEAGE. THIS ISSUE HAPPENS WHILE TURNING, WHILE ON THE HIGHWAY, WHILE IN REVERSE, AND WHILE ON A CITY STREET. I TOOK THE CAR TO PORSCHE AND THEY IDENTIFIED THAT THE CAR NEEDS A NEW TRANSFER CASE. THIS IS UNACCEPTABLE AS THIS IS EXTREMELY DANGEROUS. THIS ISSUE SEEMS TO HAVE HAPPENED ON 100S OF PORSCHES.

THE PORSCHE CAYENNE DIESEL IS DESIGNED TO NOT RESTART WHEN THE ADBLUE EXHAUST CHEMICAL IS TOO LOW. THIS SEEMS REASONABLE. HOWEVER, THE VEHICLE IS ALSO DESIGNED TO NOT RESTART WHEN THE ADBLUE REACHES A LOW POINT, EVEN WHEN IT IS REFILLED TO FULL CAPACITY. ACCORDING TO PORSCHE THE VEHICLE MUST BE BROUGHT TO AN CERTIFIED PORSCHE DEALERSHIP FOR THIS TO BE RESET, SO THE CAR CAN BE DRIVEN. AGAIN, THIS OCCURS EVEN WHEN THE ADBLUE IF REFILLED TO FULL CAPACITY. THIS SEEMS TO BE A POTENTIALLY DANGEROUS AND/OR EXPENSIVE SITUATION SHOULD THE ADBLUE REACH THIS LOW POINT AND THE VEHICLE IS A SIGNIFICANT DISTANCE FROM A CERTIFIED PORSCHE DEALERSHIP.

I EXPERIENCED A SIMILAR PROBLEM WITH MY 2013 CAYENNE S THAT WAS PREVIOUSLY INVESTIGATED (PE13-009) BY THE NHTSA IN THE PORSCHE 911. WHILE MY WIFE WAS DRIVING ON A HIGHWAY THE COOLANT HOSE COMPLETELY SEPARATED FROM THE HOUSING CAUSING THE CAR TO RAPIDLY OVERHEAT WITHOUT WARNING. EXCESSIVE SMOKE FORCED MY WIFE TO PULL OVER AND TO EXIT THE VEHICLE WITH 2 SMALL CHILDREN IN AN UNSAFE AREA OF THE HIGHWAY. A PORSCHE SERVICE FACILITY DIAGNOSED THE VEHICLE AND REPLACED THE COMPONENT AT A COST OF $5,343.56. THE VEHICLE WAS 4.5 YEARS OLD AT THE TIME OF THE REPAIR. IN RESEARCHING THE ISSUE I FOUND NUMEROUS SIMILAR COMPLAINTS ONLINE AND FOUND A RESPONSE FROM PORSCHE RELATING TO PE13-009 DATED 9/17/2013 (ATTACHED). IN PORSCHE'S RESPONSE TO QUESTION 10, THEY CLAIM THAT THE ADHESIVE APPLICATION WAS AUTOMATED AND THERE WERE NO FURTHER MODIFICATIONS OR CHANGES PLANNED. MY UNDERSTANDING IS THAT THEY SUBSEQUENTLY BEGAN THREADING THE PART IN QUESTION INSTEAD OF SIMPLY USING ADHESIVES. IN RESPONSE TO QUESTION 13C PORSCHE LISTED ONLY 2011 TO 2014 CAYENNE MODELS THAT USE A SIMILAR COOLANT PIPE CONNECTION METHOD (ADHESIVE) HOWEVER IT APPEARS THE CAYENNE GOING BACK AS FAR AS 2007 HAS A SIMILAR CONNECTION BASED ON INTERNET COMPLAINTS. IN RESPONSE TO QUESTION 14A PORSCHE LISTS RACETRACK USE AND LOW OR NON APPROVED COOLANT AS CONTRIBUTING FACTORS. IN MY SITUATION THE CAR IS USED MORE AS A MINIVAN THAN A RACE CAR. IT HAS BEEN SERVICED AT ALL RECOMMENDED INTERVALS AND ONLY AT PORSCHE SERVICE LOCATIONS. FINALLY I'D LIKE TO POINT OUT THAT THE CAYENNE AND PANAMERA ARE BOTH FRONT ENGINE VEHICLES AS COMPARED TO THE 911 THAT WAS INITIALLY INVESTIGATED RAISING NEW CONCERNS ABOUT THE LOSS OF TRACTION FROM THE LEAKAGE LOCATION. I WOULD LIKE TO REQUEST THE ISSUE BE RE-EXAMINED BASED ON THE ABOVE AND GIVEN THERE ARE FAR GREATER NUMBERS OF CAYENNES ON THE ROAD THAN THE 911. *TR
