This 2017 Peterbilt 389 is driven by Jared Gibble for Lancaster, Pa.-based Kirby Agri. The rig sports a 500-horsepower Cummins ISX15 with an 18-speed Eaton-Fuller and 3:55 rears. The truck is also equipped with Paccar low-leaf suspension. Gibble mostly hauls bulk fertilizer such as urea, potash and sulfate.
Affected trucks include model year 2008-2018 Freightliner Cascadia and Western Star 4700, 4900, 5700 and 6900 trucks. DTNA says after hard brake applications, the brake light pressure switch may not activate the brake lights with the light application of the brake pedal.
