1.What component or system failed or malfunctioned, and is it available for inspection upon request? The fuel system failure is a highly critical safety concern, and my life is at risk. It causes malfunctions with the vehicle, for example, the OBD-based emissions test has flagged a lot of (codes P219A, P0300, P0304, P0410, P0305, P0303, P0171, P0301) 5 of the cylinder misfire codes with the check engine light on, as well affecting other parts in the vehicle function properly, acceleration issues, car stalling as though it’s going to shut off. This is a serious matter and Mercedes-Benz is failing to prioritize customer safety, over cost especially when known faults in the vehicle can lead to potentially life-threatening incidents such as fuel leaks and fire hazards.
