The failure pattern owners describe
The 2012 Dodge Challenger electrical system is a minefield. The alternator (particularly the 160-amp unit in 3.6L V6 engines) fails without warning and kills all electrical power—steering locks, brakes fail, airbags disable. Owners report stalling at 40–70 mph on highways with zero warning. When it happens, you're stranded or in a ditch. The alternator smokes, the battery drains in days, and repair costs run $600–$1,300.
Dodge issued recalls (14V634000, 17V435000, T36) but dragged its feet shipping parts for months—dealers told owners "come back in October" or "we only have four alternators." Owners paid out of pocket and were promised reimbursement that never arrived or was refused outright. The V8 engine crowd got no recall at all despite identical symptoms.
The smart glass window switch is another nightmare: the driver's window cycles up and down every 10–30 seconds while the car sits, draining the battery dead overnight. This was noted in 2011 Challengers and fixed via recall; Dodge refused to apply the same fix to 2012 models made months apart. Owners unplugged batteries to prevent total drain, paid $350+ per door to replace latches, and still couldn't get warranty coverage.
Battery failures follow, along with burned wiring and fire risk. One vehicle caught fire in the trunk; another at the cigarette lighter. Service departments acknowledged the smart glass and latch problems on repair invoices but refused to fix them. You're buying a car with known defects Dodge never fully owned.

Failure modes owners describe
Alternator failure
The 3.6L V6 alternator (160 amp) fails prematurely, causing complete loss of electrical power while driving. When the alternator fails, the battery drains within days with no warning. Owners report the alternator smoking, overheating, and burning. The vehicle stalls immediately upon failure, disabling power steering, brakes, lights, and airbags. Owners cite this as a recall issue (T36, 14V634000, 17V435000) but dealers say recall parts were unavailable for extended periods or not available at all for V8 engines. Some owners paid $1,000–$1,300 out of pocket before recall parts arrived or for vehicles outside recall eligibility.
When: 30,000 to 140,000 miles; typically within first 5 years of ownership
Symptoms owners cite: Complete loss of electrical power while driving; Alternator smoking or overheating; Burning smell from engine; ABS and traction control lights flashing; Instrument panel lights flashing or going dim; Radio cutting off; Loss of power steering and brakes; Engine stall with inability to restart; Whining or high-pitched noise before failure; Battery drains within days after alternator fails
Codes mentioned: 14V634000, 17V435000, T36 recall
Repairs/costs cited: Alternator replacement $600–$1,300. Some owners paid out of pocket; dealers initially denied coverage citing unavailable recall parts. Battery replacement often needed after alternator failure ($200+). Corroded battery cables and rewiring may be required.
Recalls/TSBs owners mention: NHTSA Campaign 14V634000 (Electrical System), 17V435000 (Electrical System), T36 recall. Chrysler issued recalls for 3.6L engines (V6) only; no recall issued for 5.7L V8 engines despite identical symptoms. Recall parts were unavailable or delayed for months (October 2017 delays noted). Some dealerships told owners to pay out of pocket and request reimbursement later, with no guarantee of approval. Dealers eventually replaced alternators when parts arrived or when warranty applied, but some owners still out of pocket.
Smart glass window switch malfunction (driver-side window)
The driver-side power window operates automatically without input from the driver or ignition being on. The window moves up and down repeatedly every 10–30 seconds, causing constant battery drain. The issue occurs when the vehicle is parked and off, or while driving. It was noted in 2011 Challenger recall (CSN M24) but Dodge refused to include 2012 and later models in the service bulletin despite identical symptoms and components. Owners report needing to unplug batteries or leave windows partially down to prevent total battery discharge overnight.
When: 60,000 miles or less; occurred as early as warranty expiration
Symptoms owners cite: Driver-side window moves up and down automatically every 10–30 seconds when parked; Window operates without ignition on and no one in vehicle; Window makes clicking sounds during malfunction; Battery completely drains overnight due to window cycling; Vehicle cannot start without jumper cables; Passenger-side window may also cycle; Window seal degrades from repeated cycling; Water and debris enter vehicle interior when window left down
Codes mentioned: CSN M24 (2011 models only; not applied to 2012)
Repairs/costs cited: Diagnosis $140+. Smart glass switch or door module replacement required. Owners report replacement costs not disclosed by dealers upfront; $350 per door latch mentioned. New battery often needed after drain ($200). Service centers refused to repair under recall coverage for 2012 models.
Recalls/TSBs owners mention: CSN M24 (Customer Satisfaction Notification) issued October 2012 for 2011 Challenger only. Dodge refused to extend recall to 2012 and later models despite identical parts and symptoms. Owners told to pay out of pocket for diagnosis and repair. TSB M24 did not cover 2012 models.
Battery failure and corrosion
Battery fails prematurely, often related to alternator failure or smart glass switch drain. Heavy corrosion appears on battery posts and terminals. Battery will not hold charge after alternator failure and drains completely overnight due to window cycling or other electrical parasitic draw. Replacement batteries needed within 1–2 years of purchase on low-mileage vehicles.
When: Within 2 years of purchase; 23,000–65,000 miles
Symptoms owners cite: Battery will not hold charge; Cannot jump-start vehicle; Heavy corrosion on battery posts and terminals; Battery drains overnight; Vehicle completely dead in the morning after parking
Repairs/costs cited: Battery replacement $200–$600. Owners report having to purchase multiple batteries in short timeframe. Corroded battery posts and positive cable replacement also needed ($200+). Dealers initially blamed battery as sole cause before identifying alternator failure.
Recalls/TSBs owners mention: No recall or warranty extension for battery failure. Dealers replaced batteries as out-of-pocket repairs or under extended warranty if purchased. No root-cause service bulletin issued.
Instrument cluster and lighting malfunction
Instrument panel lights, gauge needles, and warning lights malfunction during electrical failure events. Gauges move erratically, lights flash unpredictably, and speedometer/tachometer stop working. Headlights dim or cut off while driving without warning. Interior illumination fails during daytime operation. Dashboard gauges are difficult to read during daylight.
When: Any mileage during alternator failure events; design issue from new
Symptoms owners cite: All instrument cluster lights flash simultaneously; Gauge needles spike then fall flat; Speedometer and tachometer stop working; Warning lights (ABS, traction control, brake, check engine, airbag) illuminate unexpectedly; Headlights dim or cut off while driving; Headlights flicker when brakes depressed; Interior lights turn off and on; Dash illumination absent during daytime driving; Gauges only visible when headlamps on
Repairs/costs cited: No standalone repair; occurs as secondary effect of alternator/electrical failure. Cluster repair only after alternator replacement.
Recalls/TSBs owners mention: None noted. No TSB or recall for dashboard illumination design or gauge malfunction.
Complete electrical shutdown while driving
Vehicle loses all electrical power while operating at highway speeds (40–70 mph), causing power steering to lock, brakes to fail, and airbag systems to disable. Owners lose ability to steer, brake, or maneuver. One owner had rear tire blow out from excessive brake pressure during loss of power. Immediate safety hazard with no warning.
When: Any mileage; triggered by alternator failure
Symptoms owners cite: Complete loss of electrical power while driving; Power steering locks up; Brakes become difficult or impossible to apply; No lights, horn, or airbag function; No ability to shift to neutral; Unable to activate hazard lights; Burning smell from engine; Vehicle coasts to stop
Repairs/costs cited: Alternator replacement after power restoration. Some owners incurred additional brake damage.
Recalls/TSBs owners mention: None; treated as alternator failure consequence.
Door latch and seat control electrical issues
Driver-side door latches stick or malfunction, preventing door operation. Airbag warning light illuminates and remains on after alternator service. Horn stops working after alternator or electrical service. Brake light warning illuminates. Cruise control fails to function.
When: Any mileage; post-repair issues noted

Repairs/costs cited: Door latch replacement $350 per latch. Airbag and horn issues acknowledged by dealers but not repaired during alternator service.
Recalls/TSBs owners mention: None noted. Dealers acknowledged issues on invoices but declined to repair.
Electrical fire hazard
Two narratives report vehicle fires or fire risk. One owner reported battery and wiring harness burned in trunk while vehicle idling; another reported fire starting at cigarette lighter. Burned insulation and melted jumper cable handles reported. Risk of fire from overheating alternator and corroded wiring.
When: Unpredictable; 200,000 miles and low mileage reported
Symptoms owners cite: Smoke from trunk area; Smoke from cigarette lighter; Battery and wiring harness burned; Burning smell from engine; Melted jumper cable handles; Extreme heat in battery area; Vehicle engulfed in flames
Repairs/costs cited: Fire damage requires complete electrical system overhaul. Wiring harness replacement needed.
Recalls/TSBs owners mention: None; no recall issued for fire hazard. One owner worked with insurance company for repairs.
Power module and fuel delivery issues
Totally Integrated Power Module (TIPM) malfunction causes random no-start conditions. Vehicle cranks but does not start, leaving owner stranded. Requires key cycling and fob attempts before vehicle starts. Vehicle may emit smoke from cigarette lighter. Fuel delivery issues and check engine light reported.
When: Low mileage (38,000 miles)
Symptoms owners cite: Random no-start condition; Vehicle cranks but does not start; Stuck in off/on position; No pattern to failures; leaves owner stranded; Check engine warning light on; Vehicle fails to accelerate; Abnormal noise from front end
Repairs/costs cited: TIPM replacement $1,000.

Recall parts unavailability and service delays
Owners notified of recalls but dealers could not complete repairs because parts were unavailable for weeks or months. Owners faced demands to pay out of pocket with vague promises of reimbursement. Some dealers told owners to return in future months when parts arrived. Chrysler customer service gave conflicting information and representatives acknowledged attempting to avoid reimbursement.
When: 2017 and later notifications; delays extended into 2018
Symptoms owners cite: Recall notification received but parts unavailable; Dealer says recall parts won't arrive for months; Dealer demands payment and vague reimbursement promise; Chrysler avoids committing to reimbursement timeline; Some dealerships received minimal quantities (4 alternators for entire region)
Codes mentioned: 14V634000, 17V435000, T36
Repairs/costs cited: Owners paid $1,000–$1,300 out of pocket while awaiting recall parts. Reimbursement timeline unclear or denied.
Recalls/TSBs owners mention: NHTSA Campaigns 14V634000 and 17V435000 issued but parts not manufactured or distributed timely. Chrysler customer service contradicted reimbursement commitments. One representative admitted company was trying to avoid reimbursement.
