2018 Porsche Macan: gas smell in the cabin

Filed Oct 30, 2026 · Fuel system · TX

I own a 2018 Porsche Macan with approximately 98,000 miles. My vehicle has developed a strong gasoline odor, particularly near the rear fuel-filler area, along with visible liquid leaking underneath the vehicle. There are no warning signs or error codes on the dashboard at all. The car has not been inspected by the mechanic as I am afraid to drive it now because of fire risk. I discovered the federal safety agency Recall 20V‑077 (Porsche Campaign ALA2), which addresses fuel-pump flange cracking and potential gasoline leakage. I also located an XXX, as well as multiple 2026 the federal safety agency safety complaints involving other 2018 Macans with nearly identical symptoms, including a wet fuel-pump cover and strong gasoline odor. That vehicle's VIN was reportedly excluded from the recall. I am requesting that Porsche investigate this issue as a potential safety-related defect, verify my vehicle's complete recall and service history, and explain whether my vehicle is susceptible to the same fuel-pump flange failure. Please advise whether Porsche will cover the inspection and any necessary repairs given the potential fire hazard. I am not operating the vehicle because of the fuel leak. I am a single mother to a toddler and we have to go to work and school, please assist ASAP. Thank you very much!

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 the federal safety agency 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 the federal safety agency 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.
