The 2010 Chrysler 300's electrical system shows recurring problems across multiple subsystems. Alternator failures are the most dangerous: owners report dead batteries, engine stalls at highway speeds, and in at least two cases, engine compartment fires. One vehicle caught fire at 92,000 miles after a loud pop; another at 101,000 from a battery spark. A dealer confirmed alternator short-circuit risk on 5.7L and 3.6L engines with certain amperage ratings.
TIPM (Totally Integrated Power Module) failures cause parasitic battery drain and repeated no-start conditions. One owner was stranded between states when the vehicle refused to start after parasitic draw flattened the battery. The module also triggers uncontrolled on/off cycling while parked, with lights and horn malfunctioning.
Push-button start and wireless ignition (WIN) module failures prevent starting via keyless entry. Owners must resort to physical keys. One vehicle displayed "KEY DAMAGED" messages even after key fob battery replacement and dealer reprogramming. Dealers quote $160–$187 for module replacement, though repairs often don't resolve the failure.
Additional complaints include ignition switch failure causing stalling, driver memory seat not returning to position, and unexplained engine shutdowns during normal driving. Fire-related complaints note that recall parts remained unavailable months after incidents.
Failure modes owners describe
Alternator Failure
Alternator fails, causing dead battery and engine stall while driving. In some cases, alternator may short circuit and cause electrical fire under the hood or in engine bay.
When: 90,000–101,000 miles
Symptoms owners cite: Engine stalls while driving at various speeds; Dead battery requiring jump starts; Battery warning lights illuminate; Vehicle loses power temporarily; Smoke and flames from engine bay or trunk area
Repairs/costs cited: Alternator replacement; some owners report new battery purchased to address dead-battery symptom only to have it recur due to underlying alternator failure
Recalls/TSBs owners mention: Safety Recall 14V-634 issued for alternator failures on 5.7L/3.6L equipped vehicles with 160/180/220 amp alternators; parts availability reported as delayed
TIPM (Totally Integrated Power Module) Failure
TIPM malfunction causes parasitic battery drain, starter power loss, uncontrolled vehicle wake-up cycles, and inability to start. Vehicle may turn on and off repeatedly while parked, draining battery.
When: No specific mileage stated; occurs intermittently during normal operation and while vehicle is powered off
Symptoms owners cite: Dead battery repeatedly; Parasitic draw on battery; Starter lacks power; Vehicle turns itself on/off while off; Lights and horn malfunction during wake-up cycles; Vehicle stalls without warning; Multiple false starts before engine restarts
Repairs/costs cited: TIPM module replacement required; difficult to diagnose parasitic drain initially
Recalls/TSBs owners mention: Safety Recall 10V200000 (Electrical System) exists but not all VINs included in recall scope
Wireless Ignition Node (WIN) / Push-Button Start Module Failure
WIN module or push-button start system malfunctions, preventing vehicle from starting via keyless entry or remote start. Key fob recognition fails or becomes intermittent. Vehicle may not power down with button, remaining on without key in ignition.
When: Various mileages; 50,000–124,725 miles reported
Symptoms owners cite: Push-button start does not respond; Key fob unresponsive or intermittent; Must use physical key to start vehicle; Vehicle will not shut off when push-button pressed; Key fob requires multiple presses or physical contact with start button; Remote start non-functional; Message displays 'KEY DAMAGED' even after key replacement
Codes mentioned: KEY DAMAGED message
Repairs/costs cited: WIN module replacement required; dealership programming of replacement key fob may not resolve underlying module failure; $160–$187 parts/labor reported by owners
Recalls/TSBs owners mention: Safety Recall 10V200000 (Electrical System) and related bulletins reference sensor/module fixes, but many VINs not included in recall; parts availability delays reported
Ignition Switch Failure
Ignition switch fails causing engine to shut down while driving and starting problems. Failure occurs after multiple dealer service attempts.
When: No specific mileage; occurs during normal driving and starting
Symptoms owners cite: Engine shuts down while driving; Vehicle fails to start reliably; Intermittent starting issues
Repairs/costs cited: Ignition switch replacement; owner reports expensive part replaced at owner's cost after three dealer visits
Recalls/TSBs owners mention: No recall mentioned; owner suggests stalling failure warrants recall consideration
Driver Memory Seat Malfunction
Power seat fails to return to programmed position on vehicle shutdown or exit. Intermittent failure affecting seat memory function.
When: From new (November 2010 purchase); intermittent failure
Symptoms owners cite: Driver seat does not return to memory position when vehicle shut off; Seat fails to return for easy exit approximately 1 in 7–8 times; Issue occurs when door opened before complete power-down sequence
Repairs/costs cited: No permanent fix available; workaround suggested is to remove remote start button and use key only
Recalls/TSBs owners mention: Service bulletin issued identifying sensor as root cause, but Chrysler stated no fix available; dealership diagnosed as design behavior but acknowledged all stock units exhibit same intermittent failure
Instrument Panel Electrical Malfunction
All instrument panel warning lights illuminate simultaneously while driving, indicating electrical system fault. Vehicle continues to operate but diagnostic failure unclear.
When: 80,000 miles
Symptoms owners cite: All instrument panel signals and warning lights illuminate at once
Repairs/costs cited: Not diagnosed or repaired by owner
Oil Pressure Sensor / Indicator Malfunction
Oil pressure warning light blinks and cycles on/off, disappearing under acceleration. Persists after oil sending unit replacement, indicating electrical rather than mechanical issue.
When: 10 years of ownership
Symptoms owners cite: Oil pressure light blinks intermittently; Light extinguishes when accelerating; Light returns at idle or light throttle
Repairs/costs cited: Oil sending unit replaced but problem persisted; owner suspects electrical fault in instrument panel circuit
Engine Stall While Driving
Engine shuts down completely during normal driving without warning. Power and electrical systems remain live (radio, lights stay on). Occurs at least once every 2 days in one case; intermittent in others.
When: 36,060–99,000 miles reported; no specific trigger
Symptoms owners cite: Engine stalls without warning during driving; Power steering, lights, radio remain on; Engine restarts after stall (usually); Stalling duration varies from 5 seconds to complete shutdown
Repairs/costs cited: Diagnostic codes recorded in vehicle computer showing history of shutdowns; no repairs completed by some owners
Recalls/TSBs owners mention: NHTSA Campaign 10V200000 referenced but many VINs not covered
Electrical Fire - Dashboard and Battery-Related
Electrical fires originating from alternator short circuit, battery spark, or unidentified dashboard electrical fault. Fires occur at low speeds (20–45 mph) and while parked. Flames emerge from dashboard vents, hood, or trunk with smoke.
When: 92,000–101,000 miles; one fire while parked after ignition turned on
Symptoms owners cite: Smoke emits from dashboard or trunk vents; Flames shoot from dashboard or engine bay; Fire ignites suddenly after loud popping sound or loss of power; Smoke choking occupants within seconds; Battery cable disconnection does not stop fire progression
Repairs/costs cited: Vehicles destroyed; fire department and police called; insurance appraiser on one case determined battery spark as origin
Recalls/TSBs owners mention: One fire vehicle included in NHTSA Campaign 15V313000 (Air Bags) but recall notice not sent until 5 days after fire due to parts unavailability; Campaign 14V-634 (alternator) applies to some cases
Brake Pedal / Power Loss During Braking
Vehicle stalls when brake pedal depressed, losing power mid-braking scenario. Hazardous failure affecting vehicle control.
When: 99,000 miles
Symptoms owners cite: Vehicle stalls when brake pedal pressed while driving; Loss of power while braking
Repairs/costs cited: Diagnostic test showed history of shutdowns in computer; vehicle not repaired by owner
Recalls/TSBs owners mention: Campaign 10V200000 referenced but VIN not included in recall
Tire Pressure Sensor Malfunction
Front driver-side tire pressure sensor displays false no-air-pressure reading repeatedly during normal driving. Intermittent electrical fault in sensor or gauge circuit.
When: Occurs during normal driving operation
Symptoms owners cite: Tire pressure sensor shows zero PSI in front driver tire; Warning occurs frequently and intermittently
Cold-Start Stall (Engine Shutdown 2-3 Seconds After Starting)
Engine starts but shuts off after 2–3 seconds of operation. Typically does not repeat after vehicle is turned off and restarted again. Occurs more frequently when starting after vehicle has been briefly powered off.
When: During starting procedure; more common after brief power-off periods
Symptoms owners cite: Engine cranks and starts but dies within 2-3 seconds; Does not repeat immediately on restart; Occurs more often after brief shutoff cycles
