2022 FREIGHTLINER CASCADIA

SERVICE BRAKES, AIR:ANTILOCK:MODULATOR

Daimler Trucks North America, LLC (DTNA) is recalling certain 2017-2023 Freightliner Cascadia, 2020-2023 Western Star 49X, 2021-2023 Western Star 47X, and 2022 Freightliner 114SD vehicles. The brake modulator valves on the front axle may corrode and cause the vehicle to pull to the affected side during braking initiated by Electronic Stability Control (ESC) or Roll Stability Control (RSC).

Risk: Brakes that pull to one side may cause a sudden change in vehicle direction, increasing the risk of a crash.

ELECTRONIC STABILITY CONTROL (ESC)

Daimler Trucks North America, LLC (DTNA) is recalling certain short wheelbase 2020-2024 Freightliner Cascadia, 2021-2024 Freightliner M2 Business Class, 2022 Western Star 4700, and 2020 Freightliner Classic Cascadia vehicles. The vehicle is equipped with an electronic stability control system and tire combination that may understeer during a J-turn. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 136, "Electronic Stability Control Systems on Heavy Vehicles."

Risk: Understeering during a J-turn may increase the risk of a crash.

SERVICE BRAKES, AIR:ANTILOCK:CONTROL UNIT/MODULE

Daimler Trucks North America, LLC (DTNA) is recalling certain 2022 Freightliner Cascadia vehicles. The Anti-lock Brake System (ABS) fault codes will not be stored when the vehicle is keyed off for more than 5 seconds, impairing its diagnostic features and warning light. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."

Risk: An ABS system that does not store fault codes may fail to warn the driver of an issue, or prevent proper repair. Either of these scenarios can increase the risk of a crash.

SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE

Daimler Trucks North America LLC (DTNA) is recalling certain 2022 Freightliner Cascadia vehicles. The double check valve may trap air which can impair service brake function and lock the rear axle while the vehicle is in motion. A locked rear axle may cause brake components to fail or increased stopping distance.

Risk: Brake component failure and increased stopping distance may increase the risk of a crash.

ELECTRICAL SYSTEM:SOFTWARE

Daimler Trucks North America, LLC (DTNA) is recalling certain 2022 Freightliner Cascadia vehicles. A certain combination of software and anti-lock brake system (ABS) hardware may lead to a system error, possibly causing a loss of vehicle braking and the inability to set the parking brake.

Risk: A loss of brakes increases the risk of a crash.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

Daimler Trucks North America, LLC (DTNA) is recalling certain 2017-2023 Freightliner Cascadia, 2020-2022 Freightliner Business Class M2, and 2022 Freightliner 114SD, and 2020-2023 Western Star 49X, 2021-2023 Western Star 47X, and 2021-2022 Western Star 57X vehicles. The brake modulator valves on the front axle may corrode and cause the vehicle to pull to the affected side during an Adaptive Cruise Control (ACC) braking event.

Risk: Brakes that pull to one side during an ACC braking event may cause a sudden change in vehicle direction, increasing the risk of a crash.

SERVICE BRAKES

Daimler Trucks North America, LLC (DTNA) is recalling certain 2022 Freightliner Cascadia vehicles. The emergency braking system may not engage, resulting in the loss of braking ability.

Risk: A loss of braking ability can increase the risk of a crash.

TIRES

Daimler Trucks North America, LLC (DTNA) is recalling certain 2020-2022 Freightliner Cascadia sleeper trucks equipped with Bridgestone R284, R268, or R283S ECOPIA steer axle tires in conjunction with a specific air dam. The steer tires may experience tread separation or blow-outs while driving.

Risk: Tread separation and/or blow-outs while driving may result in a loss of vehicle control, increasing the risk of a crash.

ELECTRICAL SYSTEM:12V/24V/48V BATTERY:CABLES

Daimler Trucks North America, LLC (DTNA) is recalling certain 2019-2022 Freightliner Cascadia P4, 2021 Western Star WH126, 2020 Western Star WJ121, and 2021-2022 Western Star 49X vehicles. The battery cable terminal may break, resulting in a loss of electrical power and unintended engine stall.

Risk: An engine stall increases the risk of a crash.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM

Daimler Trucks North America, LLC (DTNA) is recalling certain 2022 Freightliner Cascadia vehicles. The exhaust pipe outlet may have been improperly installed with the tip facing towards the battery box mounted directly above the frame rail.

Risk: The exhaust heat may melt the battery box, increasing the risk of a fire.

STEERING:LINKAGES:TIE ROD ASSEMBLY

Daimler Trucks North America, LLC (DTNA) is recalling certain 2021-2022 Freightliner 114SD, 122SD, Business Class M2, Cascadia, 108SD, Western Star 4900, 4700, 5700, Custom Chass RV Chassis, Custom Chass S2 Chassis, Custom Chass XC Chassis, Custom Chass XB Chassis, and Custom Chass MT Chassis. The tie rod clamps may be loose, which could result in loose tie rod ends that could break or detach.

Risk: Detached or broken tie rod ends can result in steering loss, increasing the risk of a crash.

STEERING:CRITICAL FASTENERS

Daimler Trucks North America, LLC (DTNA) is recalling certain 2021-2022 Freightliner Cascadia, Business Class M2, 114SD, 108SD, 122SD, Custom Chass S2 Chassis, Custom Chass XB Chassis, Custom Chass XC Chassis, and Custom Chass MT Chassis Western Star 4700, 4900, 5700 vehicles. The steering arm and tie rod bolts may have a defective seam that can fracture.

Risk: A fractured bolt may cause a loss of steering, increasing the risk of a crash.

ENGINE

Daimler Trucks North America, LLC (DTNA) is recalling certain 2021-2022 Freightliner Cascadia vehicles equipped with a Cummins X15 engine. The capscrews that attach the flywheel to the crankshaft may have been improperly torqued, allowing the flywheel to detach.

Risk: A detached flywheel can cause loss of drive power, increasing the risk of a crash. Additionally, driveline pieces may be ejected from the engine compartment, increasing the risk of injury.

EXTERIOR LIGHTING:HEADLIGHTS:BULBS

Daimler Trucks North America, LLC (DTNA) is recalling certain 2017-2022 Freightliner Cascadia vehicles equipped with halogen headlight assemblies. The halogen headlight bulb may dislodge during replacement and contact other vehicle components, possibly causing them to melt.
