NHTSA Complaint #11716082 — 2023 GENESIS G70

The fuel delivery system, specifically the fuel pump and fuel rail pressure system, has malfunctioned and continues to trigger diagnostic trouble code P0191 (fuel rail pressure sensor range/performance), despite a prior recall-related software update performed by the dealer, and the vehicle and all affected components are available for inspection upon request. While driving on the highway, the vehicle suddenly began stalling, hesitating, and hard jerking before losing power and entering limp mode, limiting speed to under 50 mph and forcing me to immediately pull over, which created a serious safety risk to myself and other drivers due to the sudden inability to maintain highway speeds. The issue has been confirmed by an authorized dealer through repeated diagnostic scans showing the same fuel system fault codes, and the dealer has determined the fuel pump now requires replacement, indicating the recall update did not resolve the underlying failure. The vehicle has been inspected by the dealer on behalf of the manufacturer, and prior to the failure the check engine light illuminated and has remained on since, with symptoms escalating abruptly and occurring without warning, making this an ongoing and unpredictable safety issue.
