Misfire on other Pacifica Plug-in Hybrid years

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.

What got replaced
Owners who name the part that was replaced mention the catalytic converter (3 reports).

Should you keep driving it?
This page can't tell you that. 1 of 27 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.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
