2020 Chrysler Pacifica fuel system problems

Filed Oct 22, 2026 · Electrical, Fuel system · TX

My 2020 Chrysler Pacifica Plug-In Hybrid (VIN [XXX]) is covered by safety recall the federal safety agency 26V‑362 / FCA 52D (shown as "Recall Incomplete" on the federal safety agency's VIN lookup as of October 17, 2026), high-voltage battery fire risk. FCA advises owners not to charge the vehicle and to park it outside, away from structures, until it is repaired. FCA's dealer notice states the remedy for 2020-2021 model-year vehicles became available June 12, 2026. Shortly before drop-off, the vehicle's electronics began failing intermittently; no battery warning messages appeared and there was no fire. I purchased the vehicle from Clay Cooley CJD Ram (Irving, TX) on November 27, 2020. I presented it to Meador Chrysler Dodge Jeep Ram, Fort Worth, TX on August 18, 2026 (repair order [XXX]) for this recall. As of [XXX], 65 days later, the recall repair has not been completed and the vehicle has not been returned. The dealer has provided no status updates. The dealer provided a loaner that is far below the Pacifica in quality, with much worse fuel economy. Under 49 U.S.C. 30120(c), failure to repair within 60 days after presentation is prima facie evidence of failure to repair within a reasonable time. I request that the federal safety agency look into FCA's remedy timeliness and parts availability for this campaign, including replacement battery packs, which FCA's remedy instructions say are ordered through its STAR Center only after approval, and whether FCA has met its remedy obligations for this vehicle.

I experienced a sudden loss of power and steering while driving my vehicle. The screen advised me to pull over because the engine would shut off soon, but I already had lost steering and power. I turned the car off and was able to restart it and drive it 1 mile home, and the check engine light was on. I had it towed to the dealer. After 2 weeks of testing, the dealer reported, “When your vehicle was initially checked in, the following trouble codes were present: 5 BPCM FAULT CODES P1A21-00, P1D43-00, P1C01-00, P1A2A-00, and P1A29-00. We have completed Recall Y40.” The repair tech said they expected the engine to lose power again at some point and I would need to have it towed in again to be repaired then. The repairs made so far are only software updates, no hardware has been repaired because the dealer said the errors didn’t recur after they reset the system. I have elevated the issue with the dealer and am awaiting a response. I am concerned based on the error codes and technician information that my vehicle is still at risk of catching fire at any time or experiencing another catastrophic loss of power if the faulty hardware is not replaced.

When driving on highway, electrical system started beeping and showing various signals, could no longer keep speed or accelerate. Had to put on warning lights and coast to side of road with four small kids in car. Was able to pull off to side and slowly get to safe location by resting vehicle in between events. When fully charged, didn’t seem to have issue so was able to drive to dealer. Thought was related to engine switching from electric to gas power. Dealer checked and performed two software updates. On way home from dealer, same problem occurred on highway. Super dangerous to loose all acceleration or same speed on highway! I got a video of second event as I was a passenger and my husband was driving. But as can see in video the car has a charge so the incident is not related to the switch from electric to gas power. Now we are very concerned whether Chrysler has the means to fix this at all and or whether the dealership will be actually able to identify the issue given the car was literally being driven home from the dealer. Attaching photos but have a full video. First time happened on April 4, 2026. Second on April 16, 2026

The hybrid propulsion system on my 2020 Chrysler Pacifica Plug-In Hybrid has repeatedly failed, resulting in sudden and complete loss of power while driving at highway speeds. The vehicle enters full limp mode, displays a red turtle warning light, and the motor cuts out entirely, creating a serious collision risk. The failure occurs without warning and has happened on multiple occasions. The root cause has been traced through escalating component failures: first the Power Inverter Module (PIM) was found to have an internal failure disabling regenerative braking and causing the motor to cut out; subsequently the battery charging module was found to be failing, causing the high-voltage battery to drain to 0% and stall the vehicle. Both components were replaced by an authorized Stellantis dealership under warranty. Despite replacement of the PIM, the charging module, and ultimately the transmission, the defect has not been resolved. The vehicle has been confirmed defective by the authorized dealer on each visit and has been subject to a STAR (engineering escalation) case with Stellantis. Warning symptoms include the red turtle warning light, check engine light, and sudden power loss. The vehicle has been out of service for cumulative warranty repairs exceeding 130 days, including a continuous period exceeding 90 days. The vehicle remains unrepaired and in dealer custody as of the date of this filing. The dealer has confirmed the defect on each visit and has conducted multiple rounds of diagnostic testing and component replacement, none of which have restored safe and reliable operation. The component failures are available for inspection upon request.

The hybrid battery overheated and started burning the interior of the vehicle while it sat turned off charging in the garage. Smoke filled the house which had to be evacuated. Emergency services were called and the fire department brought the incident under control. An incident report was completed by the fire department and the vehicle is currently in the possession of insurance who is doing their own evaluation. There were no warning indicators or other problems prior to this happening.

The car was running great, but then I had the check engine light on. When I checked the vehicle with an OBDD2, I got P0303 (misfired cylinder 3). A mechanic expert and I checked the vehicle for a possible blown head gasket, low compression, and defective spark plugs, and all was good. The car is a 2020 Chrysler pacifica and should have problems of this kind

The issue is the Pentastar V6 engine defect. It has caused engine misfires resulting in bucking and surging, decreased engine performance, hesitation, loss of power, premature wear on internal components. The potentially dangerous issues on the “defective design” of the engine’s needle bearings within the rocker arms, the use of sub-standard materials and procedures during manufacture, “defective or miscalibrated” ECM software, and poor quality controls. The Defect causes unsafe driving conditions because the Class Vehicles, that includes 2020 chrysler pacifica, have a significant chance of failing while being driven. Further, even the lesser symptoms of the Defect affect vehicle performance and safety, making it harder for a driver to control the vehicle as it loses power, hesitates, or misfires. the vehicle has only been inspected by the mechanic at the dealership we leased the vehicle from.
