NHTSA Complaint #11671816 — 2016 VOLKSWAGEN PASSAT

Description of the Problem: The fuel pump housing on my 2016 Volkswagen Passat (1.8L TSI) developed visible cracks, which caused a persistent fuel vapor smell around the vehicle, especially after refueling. The failed component — the plastic fuel pump assembly manufactured by Continental — is available for inspection and has been photographed. Safety Risk: The cracks allowed gasoline vapors to escape, creating a clear fire hazard. I experienced headaches from the fumes while driving, and the smell was strongest when the vehicle was full of fuel. Vapors were most noticeable when the air circulator was turned off, suggesting that fumes were entering the cabin. Confirmed by Mechanic: A certified independent mechanic confirmed the cracks after removing the back seat and inspecting the fuel pump directly. The entire assembly was replaced, and the issue was resolved. Prior to this, a VW dealership misdiagnosed the problem as a bad gasket, quoting me over $1,300 for a repair that would not have addressed the actual issue. Inspection History: The vehicle was inspected by the VW dealership first, and later by the independent shop that completed the repair. No police or insurance involvement. Symptoms: No warning lights or messages appeared. The only symptoms were the strong fuel odor, especially when the tank was full, and inaccurate fuel gauge readings leading up to the diagnosis. Summary: This issue appears similar to other known failures involving Continental-manufactured fuel pump flanges that have led to VW recalls in other models. My concern is that this defect may extend beyond currently recalled vehicles and should be investigated further.
