Daimler Trucks North America recalled 4,115 Freightliners to fix insufficient tightening of mounting bolts on brake calipers that increase the possibility of a crash.
The truck manufacturer said that in some newer models of the trucks the brake caliper mounting bolts were not tightened properly during assembly. Loose mounting bolts can reduce braking power and even cause the brakes to fail.
Daimler reported one case of a truck with missing caliper mounting bolts but no crashes. It told the National Highway Traffic Safety Administration the defect affects less than 1 percent of the recalled trucks built between January 2017 and July 2018.
Certain 2018-2019 Freightliner 108SD, 114SD, 122SD, Business Class M2, Cascadia, Columbia and Coronado models are included in the recall. Freightliner dealers will check and tighten the brake caliper mounting bolts at no charge. The recall is expected to begin October 6.
Separately, Daimler told the NHTSA it is recalling some 2018-2019 Freightliner Cascadia models because Pitman arms that attach to the steering box may crack and fracture. If that happened, a loss of steering control could lead to a crash. Dealers will replace the Pitman arms on the 116 recalled trucks built between February 2017 and July 2018. The recall begins October 6.
