A model year is listed because the code is named in its own record — a bulletin filed against it, or an owner’s complaint about it — not because every one of these vehicles sets it. Counts are documents in NHTSA’s files, not failure rates.

What P0557 means

Source: SAE J2012 / OBD-II

P0557 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 Buick and its owners have filed about it; the code’s page across every make has the whole file.

Is P0557 a known problem on Buick vehicles?

It is a documented one: NHTSA's files hold 24 manufacturer filings and 1 owner report naming P0557 on 8 Buick model years (2016–2020). 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 Buick models does P0557 appear on most?

2018 Enclave (7 documents), 2020 Enclave (4 documents), 2019 Enclave (4 documents).

Does P0557 on a Buick 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.
