The vehicle is leaking fuel from the top of the tank, filling the cabin with fuel odor. I contacted the dealership due to the recall for the 2018 Macans with this exact issue and my vehicle matches ever symptom of the recall yet they are stating my vehicle is not included and I must pay out of pocket for towing, diagnostics and repairs.

A strong gasoline odor developed around my 2018 Porsche Macan while parked in a closed garage. Over several days, the odor became noticeable inside the passenger compartment and was strongest near the rear passenger seat. No check-engine light or other warning appeared. Because of the potential fire hazard, the vehicle was towed to an authorized Porsche dealer rather than driven. The dealer confirmed the fuel odor from the rear-seat area. After removing the rear seat, the Porsche technician documented: “FOUND TOP HAT FOR FUEL SUPPLY IS CRACKED AND LEAKING FUEL.” The dealer replaced Porsche part PAC-919-679, identified on the invoice as “FLANGE WITH FUEL FILTER,” along with associated seals/parts. I learned that NHTSA Recall 20V-077 / Porsche Campaign ALA2 involves certain 2015-2018 Macans and cracking/damage involving the fuel pump/filter flange that can result in fuel leakage, fuel odor, and increased fire risk. Porsche Cars North America states that my vehicle's VIN is not included in ALA2. However, an authorized Porsche dealer documented a cracked and leaking fuel-supply flange/top hat, which appears substantially similar to the failure addressed by ALA2. I asked Porsche to explain the technical or engineering difference between my vehicle's failure and the ALA2 condition. Porsche denied assistance because the vehicle is outside warranty and its VIN is not included in the campaign, but did not provide a technical explanation distinguishing the failures. I am reporting this because an actual fuel leak and gasoline fumes entering the passenger compartment created a serious fire/safety hazard without any dashboard warning. I am concerned substantially similar failures may be occurring in Macans outside the current ALA2 recall population and ask NHTSA to evaluate whether Recall 20V-077 adequately identifies all susceptible vehicles. The Porsche dealer invoice documenting the crack, active fuel leak, diagnosis and repair is available upon request.

AT ~27,000 MILES VEHICLE CHECK ENGINE LIGHT CAME ON. NOTIFICATION ON DASHBOARD STATED 'DRIVING PERMITTED'. VEHICLE WAS SLUGGISH TO START OVER THE NEXT 2 DAYS. TOOK VEHICLE TO DEALER AND THEY IDENTIFIED A FUEL PUMP LEAK. THEY REPLACED THE FUEL PUMP AND I PICKED UP THE VEHICLE A FEW DAYS LATER. PROBLEM OCCURRED AGAIN. TOOK VEHICLE BACK TO DEALER. THEY KEPT THE CAR FOR OVER 40 DAYS (I STILL DO NOT HAVE IT) AND IT IS BEING FILED UNDER LEMON LAW. THE DEALER HAD TO REPLACE AND TEST DRIVE THE FUEL PUMPS MULTIPLE TIMES SINCE THE SECOND ONE ALSO LEAKED AND THE REPLACEMENTS LEAKED AS WELL PER THE REPAIR ORDER. PORSCHE IS CLAIMING THIS ISSUE IS 'FIXED' NOW BUT I DO NOT TRUST IT SINCE PER THE RECALL IT IS A DESIGN ISSUE AND BEFORE THE RECALLS ARE EVEN TAKING PLACE WHICH IS APRIL 2020. THE PROPOSED RECALL FIX ON CONSUMER REPORT DOES NOT SEEM TO ADDRESS MY SITUATION SINCE THE FAILURES OCCURRED AT THE DEALER EVEN ON MULTIPLE REPLACEMENT PARTS. THE RISK IS NOT ONLY A SLUGGISH START DUE TO LOW FUEL PRESSURE BUT THERE IS A FIRE HAZARD FROM THESE LEAKS. SECONDLY THERE IS A STEERING COLUMN KNOCK AND VIBRATION COMING FROM THE STEERING COLUMN AND/OR FRAME AND/OR FRONT AXLE EVERY-TIME I TURN THE VEHICLE RIGHT OR LEFT WHILE GOING UP OR DOWN A HILL OR OVER A SPEED BUMP <10MPH. THIS HAS BEEN PRESENT SINCE DAY 1 OF OWNING THE VEHICLE AND HAS GOTTEN LOUDER OVER TIME AND MORE APPARENT AS I CAN FEEL THE ISSUE UNDER THE DRIVERS SEAT FROM THE RUBBING/VIBRATION OR WHATEVER IS CAUSING THE NOISE. I CAN ALSO FEEL A VIBRATION IN THE STEERING WHEEL WHEN THIS HAPPENS TOO. DEALER HAS REFUSED TO FIX IT CLAIMING 'UNABLE TO REPLICATE THE CONDITION' 4 TIMES NOW OVER THE COURSE OF 2 YEARS. I RE-CREATED THE CONDITION FEBRUARY 17TH 2020 WITH THE SERVICE ADVISOR AND HAVE IT DOCUMENTED IN THE REPAIR ORDER. THIS IS ALSO STILL NOT FIXED.
