The national average retail price of a gallon of diesel jumped again this week, rising to its highest level in 18 months, according to the U.S. Energy Information Administration. The price rose 4.4 cents to $3.122 in the latest week.
Increasing for the tenth week in the past 11 weeks, the national price was the highest since Oct. 27, 2008, when it was $3.288.
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.
