It is a documented one: NHTSA's files hold 23 manufacturer filings and 28 owner reports naming P0303 on 17 Chrysler model years (2016–2025). Whether it is a problem on one particular car is a diagnosis, not a count — but a bulletin that names the code on your model year is the place to start.

2017 Pacifica (13 documents), 2018 Pacifica (12 documents), 2020 Pacifica (5 documents).

Does P0303 on a Chrysler mean it is recalled?

No. Recalls are filed by campaign and matched by VIN; no recall is triggered by a scan tool. Check the VIN at nhtsa.gov/recalls, or open the model year's page here for the campaigns filed against it.
