Mack Trucks recently announced that Jacobson Companies has purchased 139 day cabs and 120 sleepers, a total of 259, Mack Pinnacle on-highway commercial vehicles. A third-party logistics service chose the truck because of the fuel economy offered by the Pinnacle model, as well as the safe and comfortable in-cab driver environment. The trucks, which are equipped with Mack ClearTech MP8 445-hp engines, were distributed to Jacobson locations throughout the U.S. The model’s aerodynamic design includes a sloped hood to maximize visibility and an ergonomic wraparound dash that places all switches and controls within driver reach.

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.
