Chuck Armes of Oakland, Calif., owns this 2003 Peterbilt 379, to which he has added an 18-in. bumper, 8-in. straight pipes and a 14-in. drop visor. The truck is powered by a 550-hp Caterpillar and an 18-speed transmission. Armes hauls contaminated soil within California.
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.
