PORTLAND, Ore. – Daimler Trucks North America, LLC has agreed to recall 218,147 model-year 2017-2023 trucks due to chemical corrosion potentially impacting brake-module operation during the use of adaptive cruise control.
According to the National Highway Traffic Safety Administration Part 573 Safety Recall Report 22V-817, “On certain vehicles, chemical corrosion could affect the functionality of the brake-modulator valve, which during an Adaptive Cruise Control (ACC) braking event may result in full system pressure applied to one front wheel end causing brake pull from differential in brake force. Regular service brakes are unaffected.”
The safety risk, according to NHTSA, “A full system pressure applied to one front wheel end could lead to a brake pull resulting in a sudden change in vehicle direction due to uneven braking on the front axle increasing the risk of a motor vehicle crash.”
The number of affected vehicles, all with painted painted brake-module valves and adaptive cruise control, is one-tenth of 1 percent of the recall population which includes:
- 2021 Freightliner 108SD
- 2022 Freightliner 114SD
- 2017-2023 Freightliner Cascadia
- 2020-2022 Freightliner Business Class M2
- 2021-2023 Western Star 47X
- 2020-2023 Western Star 49X
- 2021-2022 Western Star 57X
An ABS warning light might come on providing the driver with advance notice of the problem.
The remedy for the issue is two front anodized modulator valves (one for each the left and right). Repairs will be done in phases based upon locations where corrosion is more likely and will be performed by certified Daimler dealers.
Dealers and owners are scheduled to be notified as to the recall by Dec. 30.
