# Service bulletin CSR 3075

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

Altec Industries, Inc. has received notification from Navistar, Inc. that a condition exists relating to motor vehicle safety, compliance, or emissions in certain 2022 through 2024 model year Navistar HV and MV series vehicles built from January 8, 2021, through February 10, 2023, equipped with an automatic transmission that is equipped with Altec equipment. On certain trucks equipped with an automatic transmission, if the automatic transmission is still in drive or reverse position and the stationary variable engine speed control or stationary PTO switch is engaged, the engine RPM will ramp up and may overcome parking brake hold capability resulting in possible unexpected vehicle movement. Unexpected movement of the truck can increase the risk of property damage or personal injury.
