Chrysler Pacifica RU
Weaknesses, engine ratings and buying advice
Engine Overview
The Chrysler Pacifica RU is available with 2 engine variants — from 234 to 305 hp.
FCA's workhorse V6, 305 hp, DOHC 24-valve — same Pentastar in half the Stellantis lineup. No MDS, no lifter lottery. Rocker arm tick around 60k miles. Plastic oil filter housing cracks — Dorman 926-959 metal replacement is the permanent fix. A small sleeper community runs ProCharger ($6,349) or RIPP ($6,799) kits pushing 400-450 whp on stock internals, bolt-on. Whether $12k all-in on a boosted V6 beats buying a used R/T is the question nobody agrees on.
- !! Rocker arm tick from 150,000 km
Rocker arm develops audible tick from worn contact surfaces, typically after 60,000 miles. Parts cheap ($50-80 per arm), labor drives cost due to intake manifold removal.
Symptoms: Ticking from upper engine, louder when cold, doesn't disappear after warmup - !! Oil filter housing leak — plastic cracks from 210,000 km
Plastic oil filter housing becomes brittle, develops cracks. Oil and coolant passages run through the housing — cross-contamination possible. Dorman 926-959 metal replacement is the permanent fix.
Symptoms: Oil drip under engine, low oil warning, milky residue on oil cap in severe cases - !! Timing chain tensioner stretch (2011-2013) from 310,000 km
Timing chain tensioner loses tension from chain stretch, primarily 2011-2013 units. Cold start rattle, can jump timing in extreme cases.
Symptoms: Rattle on cold start from front of engine, check engine light for cam/crank correlation
3.6-liter Atkinson V6 combined with electric drive, total system output 248 hp. 32 miles all-electric range. LG Energy Solutions battery pack (16 kWh) had serious fire problems on 2017-2018 units — two recalls, NHTSA found fire rate actually increased after the first recall fix. Power Inverter Module is the most expensive failure point after the battery pack itself.
- !! High-Voltage Battery Fire Risk (Recall 2022/2024)
LG battery cells with folded or torn anode tabs can develop internal short circuits causing vehicle fires — even when parked and off. NHTSA found fire rate actually increased after the first recall fix. Second recall issued 2024. 12+ documented vehicle fires.
Symptoms: Vehicle catches fire while parked or charging, dashboard warning lights - !! HV Battery Coolant Pump Failure from 80,000 km
Electric coolant pump for battery thermal management fails. Coolant loss can damage the HV battery pack and drastically reduce electric range or disable hybrid mode entirely.
Symptoms: Service Hybrid System warning, electric mode unavailable, coolant loss with no visible external leak - !! Power Inverter Module (PIM) Failure from 90,000 km
Power electronics between the high-voltage battery and electric motors fail without warning, can shut the vehicle down while driving. Dealer replacement part often exceeds $3,000 plus labor.
Symptoms: Service Hybrid System warning, sudden engine shutdown while driving, fault code P0E7C
Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Power Sliding Door Failure — THE Pacifica Problem Power sliding doors fail to respond or close unexpectedly. 475+ NHTSA complaints triggered a formal investigation. FCA extended warranty to 15 years/1 million miles on door lock actuators for affected VINs. Injuries from unexpected door closure documented. Symptoms: Sliding door won't open or close on command, closes by itself, door falls off track from 40,000 km | Medium | |
| TIPM Failure — Total Electrical Meltdown Totally Integrated Power Module controls all electrical functions. Internal defect causes cascading failures: fuel pump dies, windows cycle on their own, horn sounds randomly. Known Chrysler fleet problem 2008-2016. Symptoms: Random no-start, door locks cycling by themselves, fuel pump relay failure, windows operating on their own from 86,000 km | Medium | |
| Engine Stall — Crankshaft Sensor Defect (Recall) Software defect in the 9-speed transmission causes crankshaft synchronization error — engine dies while driving without warning, power steering lost. FCA recall January 2018; software update didn't help many owners. Warranty extended to 5 years/60,000 miles for crankshaft sensor. Symptoms: Engine suddenly stalls while driving, steering becomes heavy, no prior warning light from 35,000 km | Low |
