The 2015 Dodge Charger electrical system exhibits multiple failure patterns across 17 complaints. Start-up issues are the most recurrent: vehicles refuse to crank despite working lights and radio, with gear shift lights flashing, wipers activating on their own, and key fobs dying. One owner experienced a complete electrical fire at the fuse box at 107,000 miles; another lost all brake and throttle response simultaneously on the highway due to a calibration fault, a safety-critical failure.
Power drain problems plague many units: batteries die yearly even with good alternators, and several owners report lights, blower fans, and dashboard displays staying on with the engine off. One driver lost total electrical power while parked; service found a faulty computer module. The paddle shifter malfunction (upshift button causing downshift instead) appears chronic and undocumented in service bulletins despite being widespread.
Climate control and HVAC issues cluster around the driver side blend door: heat comes out cold, passengers get heat, and repair quotes run $650. Water intrusion soaks the driver-side floorboard and rear seat with no clear leak source. One fleet operator reported fuel pump electrical connectors melting and leaking fuel across 20 vehicles. Radio screens fail and drain batteries. Seatbelts lock after buckling, and instrument clusters go dark, disabling speed readout and triggering multiple warning lights simultaneously.
