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 GMC owners said

I immediately took the vehicle to the local mechanic who identified two codes (P0300 and P050D) related to the engine issues
The contact declined the repair, and the vehicle was taken to an independent mechanic, where it was diagnosed with codes: P050D, P2099, P219B, and P0300 for the fuel injector

What P050D means
Source: SAE J2012 / OBD-IIP050D 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 GMC and its owners have filed about it; the code’s page across every make has the whole file.
Common questions
Source: NHTSA files and the OBD-II standardIs P050D a known problem on GMC vehicles?
It is a documented one: NHTSA's files hold 301 manufacturer filings and 5 owner reports naming P050D on 56 GMC 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.
Which GMC models does P050D appear on most?
2018 Yukon (12 documents), 2017 Yukon (12 documents), 2016 Yukon (12 documents).
Does P050D on a GMC 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.
