Service bulletin CSR 3073

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 Kenworth Truck Company that a condition exists relating to motor vehicle safety, compliance, or emissions in a vehicle that is equipped with Altec equipment. Kenworth Truck Company has determined that a defect, which relates to motor vehicle safety, exists in certain Model Year 2021-2024 T280, T380, and T480 vehicles built from 06/17/2020 through 01/17/2023. The brake pedal plunger may become dislodged when the brake pedal is fully depressed and rapidly released. This can prevent the driver from applying the service brakes, increasing the risk of a crash. No audible or visual warning is available. The risk of the brake plunger dislodging may be reduced by slowly releasing the service brakes and not allowing the pedal to release rapidly.
