The 2004 Volvo VN has 3 recalls, the most serious being a driveshaft that can separate from the transmission while the truck is moving, creating a crash risk.
The driveshaft issue stems from bolts at the universal joint yoke that may not have been tightened to the correct specification. If those bolts loosen or back out, the driveshaft can drop free from the transmission, leaving the driver without drive power and putting a heavy rotating component in the path of other vehicles. The remaining recall affects trucks equipped with bench passenger seats, where the weld connecting the seatbelt D-ring to its anchor point may not be strong enough to hold under the load of a crash. If that weld fails during a collision, the seatbelt cannot fully restrain the passenger, raising the risk of injury.
