The defect
Kovatch Mobile Equipment Corp. (KME) is recalling certain 2021-2023 Predator, Panther, and Severe Service fire trucks. A defect in the inversion valve may delay park brake engagement, which could allow the vehicle to move unintentionally. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."
The risk
Unintentional vehicle movement can increase the risk of a crash or injury.
