Owners describe widespread electrical system breakdowns affecting core vehicle functions. The most dangerous: shift dial failures leaving vehicles immobilized (one owner stranded at -40°F with two children) and complete power shutdowns while driving at highway speeds. One owner spent over $3,000 on repeated towing and dealer repairs for a shifter fault that kept recurring—the dealer eventually found a dried-out ECM module but only after five separate service visits.
Door lock systems fail randomly, with doors refusing to unlock or trapping occupants inside. Instrument clusters flicker and black out entirely, killing fuel and tire pressure displays. HVAC actuators fail repeatedly even after replacement, with a mechanic suspecting the factory wire harness. One owner reported fuses blowing repeatedly within 15 miles of each replacement.
Other electrical gremlins include brake warning lights with dealers citing unspecified recalls, a backup camera and satellite radio that died after a Uconnect firmware update, and a heated seat system that works only when it feels like it. Weather does not explain the failures—they occur in -40°F cold and 70°F sunshine alike. Dealers have struggled to nail down root causes, with some claiming the problem is resolved when it recurs weeks later.
Failure modes owners describe
Shift dial electrical malfunction
Dial shift selector becomes unresponsive and fails to engage gear, leaving vehicle immobilized. Issue occurs randomly regardless of temperature or weather conditions, with multiple occurrences after extended troubleshooting cycles.
When: Reported at unspecified mileage; incidents in winter (-40°F) and fall weather
Symptoms owners cite: Dial shift stuck and will not move into gear; Vehicle becomes immobilized after parking; Issue clears after repeated attempts over 1-4 hours; Occurs both in extreme cold and mild weather
Repairs/costs cited: Owner cited $400 estimate for dial shift repair from Bismarck repair shops and Chrysler dealer
Recalls/TSBs owners mention: No recall or TSB mentioned by owner
Complete vehicle shutdown while driving with shifter fault message
Vehicle loses all electrical power while driving and displays SERVICE THE SHIFTER message, requiring towing. Recurs repeatedly despite multiple dealer repair attempts including shifter replacement, connector repair, ECM module inspection, and battery replacement.
When: Started February 2024; recurring incidents over 5+ months
Symptoms owners cite: Complete shutdown of vehicle power while driving at any speed; SERVICE THE SHIFTER warning message appears; Loss of all electrical systems during driving; Safety hazard with risk of accident
Codes mentioned: SERVICE THE SHIFTER message
Repairs/costs cited: Dealer replaced shifter ($644), connector ($200 diagnostic), charged $1000 for connector issue, cleaned ECM shifter module of dried coffee ($445 for battery replacement), most recent diagnosis: ECM shifter module failure
Recalls/TSBs owners mention: No recall or TSB mentioned; dealer attributed one incident to safety recalls
Door lock and unlock system electrical failure
Door locks, unlocks, and trunk release operate erratically and unpredictably via both key fob and manual buttons. Issue occurs at random intervals with no discernible pattern.
When: Intermittent failures over extended ownership period
Symptoms owners cite: Doors will not unlock via fob or manual buttons; Doors lock and trap occupants inside; Trunk will not open; Failures occur randomly with no pattern or timing
Repairs/costs cited: Dealer service attempted twice with 3-week repair stay; issue recurred within 2 weeks of return
Recalls/TSBs owners mention: No recall or TSB mentioned; dealer unable to resolve after multiple service attempts
Instrument cluster electrical failure
Instrument cluster module becomes completely non-functional, with constant flickering and blackouts. Module loses all monitoring and display functions while driving.
When: First occurred at 45K miles; persisted through 75K miles
Symptoms owners cite: Cluster completely stops operating; Constant flickering and blackout of display; Loss of fuel monitoring display; Loss of tire pressure monitoring; Loss of engine coolant temperature display
Repairs/costs cited: Owner notes 2015 Challenger recalled for same issue
Recalls/TSBs owners mention: No recall or TSB mentioned for 2015 300
HVAC actuator intermittent failure
Both AC actuators fail intermittently, preventing temperature adjustment. Issue persists even after actuator replacement and occurs both during driving and stationary operation.
When: Intermittent, daily occurrence
Symptoms owners cite: Both AC actuators fail simultaneously and intermittently; Unable to change temperature setting; Occurs while vehicle in motion or parked
Repairs/costs cited: Actuators replaced; mechanic suspects factory wire harness issue
Recalls/TSBs owners mention: No recall or TSB mentioned
Repeated fuse failures
Fuses blow repeatedly in short succession. Replaced fuses fail again within 15 miles of driving, indicating an underlying electrical circuit fault.
When: Reported at 122,760 miles; fuses blowing within 2-week period
Symptoms owners cite: Fuses blow repeatedly; Replaced fuses fail within 15 miles
Repairs/costs cited: Owner able to change fuses but they blow immediately after reinsertion
Recalls/TSBs owners mention: No recall or TSB mentioned
Brake and electronic stability control warning lights
SERVICE BRAKES and ELECTRONIC STABILITY CONTROL warning lights illuminate on instrument panel. Dealer indicated issue related to recall but did not provide campaign number.
When: At approximately 82,000 miles
Symptoms owners cite: SERVICE BRAKES warning light illuminated; ELECTRONIC STABILITY CONTROL warning light illuminated
Recalls/TSBs owners mention: Dealer stated failure related to recall; NHTSA campaign number not provided to owner
Brake pedal error message during driving
While depressing brake pedal at highway speed, electrical service fault occurs and error message directs driver to put vehicle in park. Vehicle required towing; dealer unable to determine root cause.
When: At approximately 33,000 miles
Symptoms owners cite: Brake lights electrical service illuminated; Error message appears directing to put vehicle in park; Occurred while depressing brake pedal at 70 mph
Repairs/costs cited: Dealer unable to determine failure cause
Recalls/TSBs owners mention: Manufacturer notified; no resolution or recall mentioned
Uconnect infotainment system firmware update failure
After Uconnect firmware update, multiple systems ceased functioning including backup camera, satellite radio, navigation, and engine throttle body monitoring.
When: After firmware update; vehicle parked
Symptoms owners cite: Rear view backup camera stopped working; Satellite radio stopped working; Navigation system stopped working; Throttle body error light illuminated
Codes mentioned: Throttle body error light
Recalls/TSBs owners mention: No recall or TSB mentioned
