Ford C-Max no cranking issue with multiple error codes draining the battery on Ford C-Max

Some Ford C-Max owners report experiencing no cranking issues accompanied by multiple error codes that drain the battery. These problems may stem from battery cable issues, such as corrosion on battery terminals, which can prevent the vehicle from starting. Symptoms of a dead battery, including slow engine cranks, dim or flickering dashboard lights, and clicking noises, are commonly reported among affected owners. Additionally, internal degradation of the battery due to age and problems with the alternator or starter are frequently cited as common causes of these issues. Some C-Max Energi vehicles have been noted to experience intermittent stalls or no crank situations, often linked to warning messages and fault codes from the battery energy control module. To address these concerns, owners may need to replace the drained battery with a functional one and troubleshoot the alternator if problems persist. A systematic approach to diagnosing battery health and electrical connections is essential for effective resolution of these issues.
