Overview
The Chrysler Pacifica is America's best-selling minivan, featuring class-exclusive Stow 'n Go seating, available all-wheel drive, and a choice of gasoline or plug-in hybrid powertrains. Built on the FCA platform, the Pacifica offers seating for up to eight passengers with 140.5 cubic feet of maximum cargo space. Common issues include transmission problems, EVAP system leaks, thermostat failures, and electrical system malfunctions. The PHEV variant has experienced battery pack fire recalls. With proper maintenance, these vans typically achieve 150,000-200,000 miles.

Common OBD2 Codes
| Code | Frequency | Notes |
|---|---|---|
| P0700 | Very Common | Transmission control system malfunction. Indicates TCM has detected an issue and set a code. Often accompanies other transmission codes like P0730. Common on 2020-2026 models with 9-speed automatic. |
| P0456 | Very Common | Small EVAP leak detected. Most common cause is failed purge solenoid or deteriorated O-ring on gas tank hose connection. Inexpensive fix but very frequent on all model years. |
| P0128 | Very Common | Coolant temperature below thermostat regulating temperature. Thermostat stuck open is typical cause on 3.6L Pentastar. Results in poor heater performance and reduced fuel economy. |
| P0420 | Common | Catalytic converter efficiency below threshold Bank 1. Can be caused by failing converter or exhaust manifold bolt failure allowing leaks. Sometimes triggered by oxygen sensor issues. |
| P0730 | Common | Incorrect gear ratio detected. Common transmission issue on 2020-2026 models. TCM shifts to neutral when triggered to prevent catastrophic failure. Often appears with P0700. |
| P0562 | Common | System voltage low (below 10V for 60+ seconds). Usually indicates failing alternator or corroded battery terminals. Can cause multiple system malfunctions and loss of power accessories. |
| P0340 | Occasional | Camshaft position sensor circuit malfunction Bank 1. Often wiring harness or connector corrosion rather than sensor itself. Can be related to timing chain issues on high-mileage vehicles. |
| U0100 | Occasional | Lost communication with ECM/PCM. CAN bus communication error. Check for corroded ground connections and battery voltage. Multiple modules may report communication loss simultaneously. |
| P0171 | Occasional | System too lean Bank 1. Can be caused by EVAP system leaks, vacuum leaks, or faulty MAF sensor. Often appears alongside P0456 EVAP codes on affected vehicles. |
Known Problems
The 9-speed automatic transmission experiences hard shifting, gear slipping, delayed engagement, and complete failure. Issues stem from worn clutches, contaminated fluid, software glitches in the TCM, or faulty shift solenoids. NHTSA investigated internal wiring connector shorts causing unexpected engine shutdown. Most common on 2020-2023 models including hybrid variants.
Typical mileage: 40,000-80,000 miles
Shop parts for this repairThe evaporative emission system develops small leaks from failed purge solenoids, cracked vacuum hoses, or deteriorated O-rings on the gas tank fuel filler neck connection. Very common across all model years. Causes check engine light but vehicle remains drivable. Simple diagnosis using smoke test.
Typical mileage: 30,000-100,000 miles
Shop parts for this repairThermostat gets stuck open preventing engine from reaching proper operating temperature. Most noticeable symptom is poor heater performance, especially when driving at highway speeds. Engine takes longer to warm up and fuel economy decreases. The entire thermostat housing assembly typically requires replacement on the 3.6L engine.
Typical mileage: 60,000-120,000 miles
Shop parts for this repair2017-2021 Pacifica PHEV models can experience battery pack fires even when parked and turned off. Caused by internal battery cell defects including torn anode tabs and rotor bearing installation issues. Multiple recalls issued (23V-010 for transmission-related fires, separate recalls for battery pack fires). Owners advised to park outdoors away from structures until repairs completed.
Typical mileage: Any mileage
Shop parts for this repairPower sliding doors fail to open or close properly. Door buzzing when locked indicates failing actuator. Actuators can fail prematurely and multiple doors often fail around the same time. Models with power sliding doors require full latch assembly replacement rather than just actuator. Common on 2017-2024 models.
Typical mileage: 50,000-100,000 miles
Shop parts for this repairCatalytic converter efficiency drops below threshold triggering check engine light. Can be caused by actual converter failure, exhaust manifold bolt breakage allowing leaks, or faulty oxygen sensors. Manifold bolts fail due to heat cycling and fall off. Oxygen sensor wiring and connectors prone to corrosion. Common on higher mileage vehicles.
Typical mileage: 80,000-150,000 miles
Shop parts for this repairAlternator fails to maintain proper system voltage causing electrical system malfunctions, dimming lights, and potential stalling. Battery terminal corrosion exacerbates issues. Can trigger multiple module communication errors when voltage drops below 10V. System voltage should be 13.5-14.5V when engine running.
Typical mileage: 80,000-120,000 miles
Shop parts for this repairPowertrain control module develops internal memory checksum errors or processor faults. Can be caused by low battery voltage, physical damage, water intrusion, or connector corrosion. Sometimes appears as phantom code with no other symptoms. May require PCM replacement or reprogramming. Check battery voltage and connectors before replacing module.
