PORTLAND, Ore. – Daimler Trucks North America, LLC (DTNA) has agreed to recall certain 2021-2022 Freightliner Custom Class XC Chassis intended for use in the motorhome industry because the brake-pedal return spring might not have been installed during production.

The recall covers 276 of the chassis built between June 18 and Oct. 9, 2020 and equipped with adjustable pedal assemblies.

According to the National Highway Traffic Safety Administration (NHTSA) Part 573 Safety Recall Report 21V-108, a missing brake-pedal return spring could allow the pedal to remain in the “down” position, thus potentially keeping the brake lights illuminated. Additionally, in certain towed vehicles, the service brakes may also stay engaged.

The report specifically cites the following potential safety issues should this defect occur: If the brakes lights stay illuminated after the brake pedal is released, an additional service brake application will not cause the brake lights to illuminate and would not signal to other motorists the intent of the driver to slow the vehicle, potentially leading to an increased risk of a crash. In addition, if the brake activation signal to a towed device remains active when the motorhome chassis service brakes are released, the brakes on a towed device may potentially remain engaged depending on brake configuration of the trailer.

The fix is relatively simple: Daimler Truck dealers will inspect affected vehicles and install a brake-return return spring where necessary.

Dealer and owner notification is scheduled to begin April 24th.
