# Service bulletins for the 2020 Honda Fit

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.

45 bulletins from NHTSA, as of 2026-10-19.

- [A22010A](/bulletins/10215486.md), 2022-07-07, Service bulletin: FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING; EQUIPMENT. "Service news article \- When diagnosing a Fit within the above VIN range with a misfire complaint, start by doing service bulletin, 21\-007 \(Carbon Buildup with Misfire DTCs\) instead of replacing fuel injectors.

Replacing those injectors may have reduced the number of misfires temporarily, but most likely didn’t address the actual cause of the misfire.
