The 2006 Volvo VN has 5 recalls, the most serious involving cracking aluminum wheels and rear axle spindles that can fracture and shed a wheel while the truck is moving, with no warning before loss of control.
Recalls 2 and 3 describe the same spindle defect across different rear drive axle series: the spindles can develop fractures that allow a wheel to separate from the truck at speed, creating a serious crash risk for the driver and anyone nearby. The wheel cracking issue is separate, affecting trucks equipped with specific Accuride aluminum wheels that were not properly pre-stressed during manufacture, leaving them vulnerable to cracks that grow over time until the wheel fails. There is also a concern with the fifth wheel hitch on trucks equipped with an air-release coupling: the inversion valve on the frame can be positioned in a way that lets dirt and moisture enter through the exhaust port, corroding the brake valve inside until it malfunctions and releases the fifth wheel's locking mechanism unintentionally, which could allow a trailer to detach. On the occupant safety side, the bench passenger seat belt's d-ring weld may not be strong enough to hold under crash loads, meaning the belt can pull free and fail to restrain the passenger when it matters most.
