2023 Dodge Charger Electrical Problems

Your 2023 Dodge Charger has experienced multiple engine shutdowns while driving due to high-voltage electrical faults in the CAN bus system, likely related to the telematics unit. You're also experiencing severe fuel economy loss (around 10 MPG instead of normal), and the dealership has advised against driving the vehicle due to safety concerns but has refused to perform repairs. The problem has persisted for nearly a year without resolution despite multiple service attempts.

Your car is experiencing ongoing electrical problems with the infotainment system, which repeatedly downloads files and displays fatal error messages that can't be fixed. There are also issues with the telematics system and the vehicle's communication network (CAN bus), and even after two engineers inspected your car, the problems remain unresolved. Additionally, your headlamps are receiving abnormally high voltage that exceeds safe levels. Fixing this will likely require comprehensive electrical diagnostics, software updates, and possibly replacement of the infotainment control module or voltage regulators.

Your car stalled unexpectedly while driving without any warning lights appearing on the dashboard. After you restarted it and took it to the dealer, they found that the wiring harness had failed and needed to be replaced. The dealership identified the problem but hasn't completed the repair yet, and Dodge is investigating the issue.
