Service bulletins for the 2022 Kenworth T880

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.

71 on file from NHTSA, as of 2026-10-19.

A warning will appear on the dash display when communication is lost, including transmission or engine warnings, “!” next to DNR/DNRP indicator, “-“ in the DNR/DNRP indicator, and/or chimes, depending upon whether you are operating a diesel/gas or battery electric vehicle.
