LT Leather, RS; required with RS; the guides print H0Y1, the footnote mark 1 (required when RS is ordered) attached, and no page prints the bare code (the 2018 guide p.65, the 2019 guide p.92), so the row carries no factory citation
- 2017–2018 Factory-verified
LT, Premier; front bucket seats (A51); LT: requires PCQ; 2017 from the page of GM's 2017 order guide that prints the bare code; the 2016 color and trim page prints H0Y2 with the footnote mark attached and the PCQ and floor mat footnotes only name H0Y, so 2016 is left out
This page aggregates every documented appearance of H0Y in the Chevrolet reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
