Dodge Ram 3500 repeated computer failures leading to five replacements on Dodge Ram 3500

Some Dodge Ram 3500 owners report experiencing repeated computer failures that have necessitated multiple replacements, often linked to common issues with the Uconnect radio and faulty batteries. Additionally, specific components like the Hydraulic Control Unit (HCU) have been noted for their tendency to fail repeatedly, even after being replaced, suggesting potential defects. In cases of instrument cluster failures, some owners find that opting for repair rather than replacement is advisable, particularly for backlight issues caused by burnt-out LEDs or bulbs. Furthermore, dealer responses to these problems vary, with Ram reviewing reported issues to determine warranty coverage and repair instructions. Users have also shared experiences of malfunctions in the computer system, such as double chimes and power fluctuations, indicating that these problems may not be isolated to individual vehicles but rather affect other Cummins 6.7 owners as well.
