What Jeep owners said

Owners’ own words, scrubbed of anything identifying. Unverified reports filed with NHTSA — what was said, not a finding that it was true.

We live in galveston county so when it turned on we took it to autozone for the free code check - the code read was P20E8 and it just said emissions code

P20E8 sits in the generic range of the OBD-II standard, so it means the same thing on every vehicle sold in the United States — but WhichTrim does not carry a definition for it and will not invent one. What is on this page is the record: who named it and on what.

A stored code names the test that failed, never the part that caused it. The record above is what Jeep and its owners have filed about it; the code’s page across every make has the whole file.

Is P20E8 a known problem on Jeep vehicles?

It is a documented one: NHTSA's files hold 47 manufacturer filings and 1 owner report naming P20E8 on 7 Jeep model years (2017–2021). 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.

Which Jeep models does P20E8 appear on most?

2018 Grand Cherokee (10 documents), 2017 Grand Cherokee (9 documents), 2021 Wrangler (8 documents).

Does P20E8 on a Jeep 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.
