Mercedes-Benz E350 engine not starting despite new battery on Mercedes-Benz E350

Some Mercedes-Benz E350 owners report experiencing issues with their engine not starting even after installing a new battery. These problems may arise from several factors, including the possibility that the new battery was stored for an extended period before installation. Additionally, owners have noted that alternator failure can prevent the battery from charging, leading to starting issues. Some owners find that even a new battery can be weak, which is critical for the vehicle's operation, and regular checks for corrosion and voltage levels are recommended. Fuel system defects have also been reported as a cause for starting failures, highlighting the importance of ensuring the fuel system is functioning properly. Furthermore, some owners experience electrical issues where the lights and accessories work, but the engine does not crank, indicating a need for further investigation. It is advisable for owners facing these issues to consult a professional mechanic for a thorough inspection and appropriate solutions.
