Defect. Pierce Manufacturing (Pierce) is recalling certain 2017-2018 Pierce Arrow XT, Dash, Enforcer, Impel, Quantum, Saber, Velocity, and Commercial vehicles equipped with Whelen accessory brake lights. Depending on the specific wiring of the vehicle, these brake lights may illuminate when the brake pedal has not been pressed. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk. If the brake lights incorrectly illuminate, it can confuse other drivers, possibly increasing the risk of a crash.
Remedy. Pierce will notify owners, and Whelen will inspect the vehicles and replace the brake lights, as necessary, free of charge. The recall began March 4, 2019. Owners may contact Pierce customer service at 1-888-974-3723.
