Daimler Trucks North America recalled more than 21,000 vehicles to fix a variety of defects on its heavy-duty trucks and school buses.
Daimler is the largest seller of heavy-duty trucks in the U.S.
The first recall is to fix faulty caliper bolts that may loosen and detach on nearly 15,000 2017 through 2019 Daimler trucks, including Freightliner 108SD, 114SD, M2 Business Class and the Cascadia. Also included are Freightliner Custom Chassis S2C 106 Cab, S2G, XBR, XBS, XCL, XCM, XCP, XCR and XCS vehicles as well as Western Star 4700, 4900 and 5700 trucks.
The defect may affect the ability of the vehicles to brake and increases the risk of a crash, according to the National Highway Traffic Safety Administration.
The company also is issuing a second recall of nearly nearly 5,200 2017 through 2019 Thomas Built Buses, including the Saf-T-Liner C2, Saf-T-Liner EFX and Saf-T-Liner HDX. As with the trucks, the bus recall has to do with loose brake caliper mounting bolts.
The trucks and buses were built between Jan. 3 and Oct. 31, 2017 and assembled at the company’s York Manufacturing Plant.
Daimler plans to notify owners and dealers in late July. Dealers will inspect the brake mounting bolts for loose bolts and tighten them if necessary. Repairs will be performed by Daimler authorized service facilities.
A third recall is for nearly 600 2012 through 2019 Western Star 4900 trucks that could have potential problems with the front brake hoses.
The recall affects certain Western Star 4900 trucks built with Lowmax hoods and disc brakes. Insufficient clearance between the front brake hose and the hood may result in the brake hose being chafed.
“Front brake hose chafing may cause air loss, possibly reducing braking effectiveness and increasing the risk of a crash,” according to NHTSA.
Dealers will inspect the trucks and will replace the front axle hose if a problem is found.
The recall is planned to begin on July 27.
