The 2022 Chrysler Pacifica electrical system shows a pattern of catastrophic failures. Most critical is sudden loss of motive power—the engine shuts down without warning or with only brief dashboard notice ("Stop Safely Vehicle Will Shut Off Soon" with turtle icon) while driving at 70+ mph on highways. Owners report being forced to navigate multiple lanes of traffic to reach the shoulder, often with children in the vehicle. Multiple owners say this has happened 5–10+ times; one owner experienced it six times in three days.
Dealerships have applied recall software updates (NHTSA 23V010000), but owners confirm the shutdowns continue after the update. The underlying issue appears to be a wiring harness fault in the hybrid powertrain—one specific code, P0A43 (Drive Motor 'A' Position Sensor Circuit Intermittent), appears in several complaints, and owners cite transmission wiring as the likely culprit. Dealers are unable to replicate the problem or locate the root cause.
Beyond shutdown, owners report the auto stop/start feature malfunctions at traffic lights, the electrical system browns out completely while driving (leaving the vehicle immobilized), unintended acceleration occurs, and phantom braking has caused injury. One owner's hybrid battery thermal management component failed out-of-warranty, and Chrysler refused coverage. Dealerships often can't diagnose the issue, parts are backordered 10+ weeks, and Chrysler has offered no timeline for a permanent fix.
Failure modes owners describe
Loss of Motive Power / Unannounced Shutdown
Engine and drivetrain shut down without warning or with brief dashboard warning (typically turtle symbol and 'Stop Safely Vehicle Will Shut Off Soon' message). Vehicle loses all acceleration, requiring immediate steering to shoulder or off-ramp. Multiple owners report this occurs at highway speeds (70+ mph) creating extreme hazard. Some instances preceded by limp-mode operation at 15–20 mph.
When: Reported from 17,602 miles to 100,700+ miles; occurs randomly regardless of state of charge on hybrids
Symptoms owners cite: Complete loss of motive power while driving; Engine stalls with brief or no warning; Dashboard warning 'Stop Safely Vehicle Will Shut Off Soon' with red turtle icon; Vehicle enters limp mode (reduced to 15–20 mph) before shutdown; Unable to restart immediately; requires several minutes or vehicle restart spontaneously; Shutdown occurs at 25–80 mph with no predictable trigger
Codes mentioned: P0A43 (Drive Motor 'A' Position Sensor Circuit Intermittent), C2225 (Status: MIL - PCM Disabled EDU)
Repairs/costs cited: Software update issued via recall (NHTSA 23V010000) has not resolved problem for multiple owners. Owners report wiring harness fault suspected. No permanent fix documented.
Recalls/TSBs owners mention: NHTSA Campaign 23V010000 (Electrical System, Hybrid Propulsion System) issued; parts on backorder up to 10+ weeks. Software update applied but fails to prevent recurring shutdowns. Dealerships unable to replicate or diagnose underlying cause.
Hybrid Battery Thermal Management Failure
High-voltage battery coolant heater sealed component fails, triggering P0E15 code and check engine light. Non-wear part fails without service interval. Loss of proper battery temperature control affects hybrid operation, regenerative braking, and power availability. Failure can cascade into limp mode or reduced power.
When: At 100,700 miles on one 2022 model; component non-wear and sealed so timing unpredictable
Symptoms owners cite: Check engine light illumination; Reduced hybrid system power output; Potential for limp-mode operation as vehicle protects battery
Codes mentioned: P0E15 (Hybrid/EV Battery Pack Coolant Heater 'A' Control Performance)
Repairs/costs cited: Coolant heater replacement required; estimate ~$1,900 out-of-pocket cost reported
Recalls/TSBs owners mention: Chrysler/Stellantis denied warranty/goodwill coverage despite failure of non-wear component immediately beyond hybrid warranty threshold (100,700 miles); cited internal policy without written justification. Corporate stated no justification available beyond automated denial prompt.
Auto Stop/Start Malfunction
Stop/start feature activates unexpectedly or fails to restart engine smoothly, causing stalling at traffic lights and intersections. Feature also engages in inappropriate conditions or causes hard restarts. One owner reports feature may contribute to starter wear.
When: Reported from purchase/early ownership
Symptoms owners cite: Vehicle shuts off at traffic lights or intersections when stop/start activates; Hard restarts or failure to restart after stop/start engagement; Stop/start activates at low speed or when not intended; Multiple hard restarts in short sequence; Service message 'Stop/Start Unavailable, Service Stop/Start' appears after event
Repairs/costs cited: One owner reports starter replacement performed; mechanic suspected stop/start function contributed to premature wear from repeated cycling and heat exposure from catalytic converter
Unintended Acceleration
Vehicle accelerates without driver input on accelerator pedal. Once brake is released, vehicle continues to accelerate. Accelerator pedal becomes unresponsive to depression. Multiple failure instances at various speeds including 70 mph.
When: At 41,607 miles
Symptoms owners cite: Vehicle accelerates while foot off accelerator pedal; Continued acceleration after brake pedal is released; Accelerator pedal unresponsive when depressed; Unknown warning lights illuminate during event; Failure occurs multiple times at different speeds (35–70 mph)
Codes mentioned: Fault codes from accelerator pedal assembly and main computer reported but later disputed by dealer (stated no codes present)
Repairs/costs cited: Vehicle not repaired; independent mechanic found 12-volt battery not at full charge; dealer noted accelerator pedal and main computer fault codes but later retracted statement of code presence
Recalls/TSBs owners mention: Manufacturer informed and case opened but later closed; no repair performed
Electrical System Brownout / Loss of All Power
Complete loss of electrical power while driving at low speed, affecting engine, instruments, lights, and parking brake. Vehicle becomes uncontrollable and undriveable; owner trapped unable to engage hazard lights or place vehicle in park. Power returns minutes later with 'Service Electrical System' message.
When: Intermittent from early ownership; also occurs when parked overnight
Symptoms owners cite: Total electrical system loss while driving at ~15 mph; No dashboard instruments operative; Hazard lights inoperative; Engine stalls; brake pressure maintained but parking brake non-functional; Vehicle immobilized in roadway; Power spontaneously returns after minutes; Service Electrical System message appears after recovery; Repeated episodes when parked overnight; vehicle unresponsive in morning then restarts on its own
Multiple Electrical and Drivetrain Warning Codes with No Diagnosis
Vehicle displays simultaneous warning messages across multiple systems (service electronic stability control, lane sense, AWD, brake, shifter, parking brake) with no clear root cause. Two dealerships replaced STAR connector and ABS module without resolution. Chrysler engineers unable to identify or fix underlying issue.
When: Starting June 2023
Symptoms owners cite: Service electronic stability control warning; Lane sense unavailable warning; AWD system unavailable warning; Service shifter message; Service parking brake message; Service brakes message; Multiple dashboard warning lights illuminating together; 8 stored ABS trouble codes relating to low voltage and electronic failures across multiple systems (reported in separate complaint)
Codes mentioned: ABS trouble codes (multiple, relating to low voltage and electronic failures across systems)
Repairs/costs cited: STAR connector replaced at first dealership; ABS module replaced at second dealership; neither resolved issue. Vehicle has been at dealerships since June 2023 with no permanent fix. Dealership documentation incomplete pending final repair.
Recalls/TSBs owners mention: Chrysler engineers guiding dealership troubleshooting; neither dealership nor Chrysler engineers able to determine root cause or effective repair
Phantom Braking
Vehicle brakes engage suddenly and forcefully without driver input, triggered by minor road surface disturbance (divot). Airbags deploy as result. Owner injured.
When: Triggered at low speed (gas station entry) by road surface
Symptoms owners cite: Sudden brake engagement without warning or driver input; Triggered by minor road surface irregularity; Airbags deployed upon sudden halt; Owner sustained concussion, neck injuries, hip injuries, nose injury, thumb injury, severe hand and arm burns and bruising
Repairs/costs cited: Vehicle towed to independent mechanic; current whereabouts unknown
Recalls/TSBs owners mention: Dealer and manufacturer not yet notified at time of report
Transmission Wiring Harness Fault / Loose Connection
Transmission-related electrical connection fails or becomes loose, causing engine shutdown and limp-mode operation. One early report (2/2022) identified loose cable at transmission; tightening provided temporary fix but shutdowns recurred. Later reports suggest wiring harness defect rather than connection issue.
When: From early ownership (Feb 2022 reported); recurrent through model year
Symptoms owners cite: Engine shutdown while driving, particularly on highways; Check engine light illumination; Transmission warning light illumination; Multiple shutdowns in sequence before resolution; Shutdown occurs without warning or after extended period after first incident
Repairs/costs cited: One 2022 incident: loose transmission cable disconnected and reconnected by dealership; problem recurred. Owners suspect permanent wiring harness defect rather than loose connection.
12-Volt Battery Depletion / Charging Failure
12-volt battery depletes and requires replacement. One owner reports three Chrysler vehicles required 12-volt battery replacement; one required two replacements. Possible charging system or high-draw electrical fault.
When: Reported from vehicle at rest and in use
Symptoms owners cite: Vehicle will not start; Repeated battery depletion events across multiple Chrysler vehicles same owner; Battery requires replacement rather than recharge
Repairs/costs cited: Batteries replaced (two replacements in one case)
Steering Loss or Control Loss During Shutdown
When vehicle loses power and shuts down, steering and brake control compromised or lost, creating hazard when vehicle must be steered to roadside while losing hydraulic assist.
When: Concurrent with shutdown events
Symptoms owners cite: Loss of steering assist during power loss/shutdown; Difficulty steering vehicle to safe location when electrical power lost; Brake assist compromised during shutdown event
