Misfire on other Pacifica years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2022, 2023, 2026.
What this problem usually is
These reports start with the check engine light. Many describe the engine running rough or shaking at idle, a P0300-series code, or a catalytic converter code. A worrying number say the light was flashing. Owners often list ignition coils or spark plugs already replaced, and the light coming back afterward.
What got replaced
Few of these reports name the part that was replaced.
Recalls and investigations

The battery pack may cause a vehicle fire, even when the vehicle is parked with the ignition in the "Off" position.
An internal transmission wiring connector may short circuit, resulting in an unexpected engine shutdown.

“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”

“While driving my kids to school I experienced my first loss of power on my vehicle, where an error message appeared in the instrument cluster stating "shift to P to start" with the P indicator on the shifter flashing. No check engine light was produced. I was on surface streets driving at 20mph, this could have been worse of I was on the freeway, especially with my kids in the vehicle.”

Should you keep driving it?
This page can't tell you that. 0 of 25 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
