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.

## NHTSA's summary

CONDITION Isuzu Motors Limited has decided that a defect exists in certain 2022 model year Isuzu F\-Series vehicles. Due to a software calibration error, the affected vehicles were built without engine exhaust braking functionality. Without engine braking, a driver may experience longer stopping distances than expected, increasing the risk of a crash. CORRECTION Isuzu dealers will have the Cummins Engine Control Module \(ECM\) reprogrammed with the correct calibration setting for the engine exhaust brake. This service will be performed free of charge.
