Kenworth is now offering extended protection plans for its 2013 Paccar MX-13 engine. The 12.9-liter engine is designed to meet demands of heavy-duty trucking and is available in Kenworth Class 8 models. Extended warranty coverage options range from three to seven years and from 100,000 to 700,000 miles. The extended coverage is available when ordering the engine, purchasing a new Kenworth truck or up to 18 months following a purchase. A $400 registration fee is required for extended warranty orders placed from 13-18 months after truck purchase.
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.
