PORTLAND, Ore. – Daimler Trucks North America, LLC (DTNA) has agreed to recall two different Freightliner models to rectify two different brake issues.

The first recall is for certain model-year 2022 Freightliner Cascadia trucks to correct a braking-system software issue which might lead to loss of braking.

The recall population contains nine trucks produced between May 12 and Nov. 18, 2021, with a certain limited-production software version and a specific antilock braking electronic control unit (ABS ECU).

According to the National Highway Traffic Safety Administration (NHTSA) Part 573 Safety Recall Report 22V-101 “It is possible to have a braking system error on vehicles with a certain combination of software and ABS hardware, which can lead to a loss of vehicle brakes, including alternate method of setting the parking brake.”

The situation came to the company’s attention when it received a report on February 18th this year for unresponsive brakes on a Cascadia test vehicle. Freightliner’s engineers reported unresponsive brakes while resetting the anti-lock braking system’s electronic control unit while operating at low speed.

DTNA opened an investigation, reproducing the event and reviewing the affected population. It identified nine Cascadia trucks.

The remedy will be updating the software at franchised Daimler Truck dealers.

Dealers and owners are scheduled to be notified about the recall by April 23rd.

The second recall covers 11 2020-2022 Freightliner M2 trucks to repair a problem which might lead to cracked brake drums.

According to NHTSA Part 573 Safety Recall Report 22V-118, “On certain Freightliner M2s equipped with certain brake drum and hub combination, the brake drum may interfere with the hub assembly possibly resulting in a cracked drum, which in turn may compromise the vehicles braking capabilities.”

In August 2021 DTNA received a report of cracked brake drums on three vehicles. Research revealed the drums were not compatible with the vehicles’ hubs and a subsequent investigation went through Feb. 2022 which determined the 11 vehicles included in the recall.

Repairs will be made to the recalled vehicles by franchised DTNA dealers.

Dealers and owners are scheduled to be notified by April 30th.
