Certain 2019 – 2023 model year Genesis G70 vehicles may have a Fuel Control Valve \(FCV\) in the High\-Pressure Fuel Pump \(HPFP\) assemblies that could allow excess fuel to enter the fuel pump. This condition may result in a reduction or loss of motive power at low speeds. The vehicle will also have Diagnostic Trouble Code \(DTC\) P0088.
