The 2021 Volvo VHD has 6 recalls, the most serious involving two brake system defects: a brake pedal that can break loose and become inoperable, and an air brake line fitting that can release under pressure and cause the park brakes to apply without warning.
On the steering side, a king pin nut may not have been installed or fully tightened during axle assembly, which can allow the steering knuckle to separate from the axle entirely, a situation that would leave the driver with no directional control. The electrical system also has a concern: trucks equipped with the Bendix EC80 electronic control unit can experience signal interference that causes the unit to misprocess commands or stop responding, disabling safety systems including anti-lock brakes, electronic stability control, automatic traction control, and the collision mitigation system all at once. The passenger-side bench seat may not be firmly anchored to the floor, meaning the seat can shift during a crash and leave that occupant without proper restraint. Finally, a faulty compression spring in the hubcap assembly can allow the hubcap to separate from the wheel while the truck is moving, putting debris in the path of other vehicles.
