Daimler Trucks North America is recalling 436,095 Freightliner and Western Star models to repair brake signals that do not properly illuminate when only light brake pedal pressure is applied by the driver.

The recall includes 2008-2018 Freightliner Cascadias and Western Star 4700s, 4900s, 5700s and 6900s produced between March 27, 2007 and Oct. 30, 2017.

The National Highway Traffic Safety Administration said the brake light pressure switches did not properly activate the lights when the pedal was lightly applied.

The Cascadia is the best-selling truck in the heaviest Class 8 weight segment in North America. Western Star is largely known for its customizable semi-tractors.

In its defect information report Daimler submitted to safety regulators on Nov. 27, the company blamed the malfunction on a part made by Kendrion Inc. The Dutch company makes many auto parts, including  pressure switches for air brake systems. After several rounds of testing dating back to 2015, Daimler concluded that it was possible for air pressure to build between the sensor and connector over time, preventing brake lights from activating with light brake pedal pressure “after several hard applications of the brake.”

The recall is planned to begin Jan. 25, 2018. Repairs will happen at all Daimler authorized service facilities free of charge.
