Service bulletin PIT6031A
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

The document
The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

| GMC SIERRA 1500 | 2019, 2020, 2021, 2022 (the catalog's model; the bulletin names a series or trim of it) |
