Fuel Leak due to Suction Jet Pump Failure within Fuel Tank (Remedy Effectiveness of Recall 16V647)
On December 12, 2023, the Office of Defects Investigations (ODI) opened RQ23-007 to investigate the remedy repair effectiveness and scope of Volkswagen (VW) recall 16V-647. Recall 16V-647 was issued on September 2, 2016, for a defective suction jet pump (SJP) inside the fuel tank. Failure of the SJP could lead to a fuel leak from the vehicle. This recall covered certain model year (MY) 2015-2016 Volkswagen Golf and Audi A3 passenger car vehicles. The recall remedy repair replaced SJP Version 1.0 with an improved version, Version 1.1. The SJP is designed to purge fuel from the evaporative emissions (EVAP) system. VWâs recall filing stated the SJP may have been damaged during assembly, which could potentially allow fuel to flow directly into the EVAP system. Over time, the fuel could accumulate in, and cause a leak from, the charcoal canister filter element. ODI received consumer complaints of SJP failure leading to a fuel leak, refueling spit back, refueling shutoff, and/or fuel odor in vehicles previously repaired under recall 16V-647. Additional complaints alleging SJP failure leading to the previously stated outcomes were received in vehicles outside the scope of recall 16V-647
Vehicle Stalling - Manual Transmission
The Office of Defects Investigation (ODI) has completed its review of a defect petition received on 14 August 2019 requesting an investigation of an alleged defect of the manual transmissions in Model Year (MY) 2019 Volkswagen (VW) GTI, Golf GTI and Jetta GLI vehicles. The stalling incidents cited occurred without warning as the vehicle slows to a stop or prepares to make a turn across traffic with the clutch pressed in and the vehicle in neutral.The hazard posed by a vehicle stalling event is manifested in the inability of the vehicle to move with the flow of surrounding traffic. Two factors have a major impact on the potential hazard to the vehicle, its occupants and surrounding vehicles: the surrounding traffic speed and the subject vehicle's restart ability. In the case of the vehicles that are the subject of this petition, restart is immediate and the stalls occur when the vehicle is slowing to stop for a traffic signal, making a turn, or is completely stopped. These circumstances substantially reduce the risk of harm to the vehicle, its occupants and surrounding vehicles.As of March 2, 2020, out of the population of 11,333 subject vehicles, NHTSA has identified 214 consumer c
