The 2002 Volvo VN has 5 recalls, the most serious being two separate crash risks: a drive axle that can shift out of alignment and destabilize the truck, and a fifth wheel latch that can release unexpectedly while parked with the brake set, potentially separating the trailer without warning.
The fifth wheel issue involves a solenoid valve malfunction that allows air to reach the latch mechanism even when the park brake is engaged, so a loaded trailer can detach while the truck is stationary. On the suspension side, the upper forward or rear drive axle seat can crack and break, letting the axle shift position and compromising the truck's handling and directional stability while moving.
There is also a fire and reliability concern in the engine bay: the pre-heater wiring harness was assembled incorrectly and can overheat, damaging the pre-heater itself and nearby heat-sensitive components, and leaving the engine difficult or impossible to restart. Two related recalls address the center-passenger seatbelt mounting bracket on trucks equipped with bench passenger seats: the weld securing the D-ring anchor nut may not be strong enough, meaning the anchor point can pull free in a crash and the belt may fail to hold the occupant in place.
