The 2001 Volvo VNL has 5 recalls, with multiple issues that can cause complete loss of steering control on this Class 8 heavy truck, as well as a wiring defect that can lead to a fire.
Two recalls address the steering shaft: a shorter shaft from a different Volvo model may have been installed, and when the steering column is adjusted through its normal range, the mismatched shaft can be pushed outside its intended operating zone. Over time, that accelerated wear can result in the steering shaft failing entirely and the driver losing the ability to steer. Separately from the shaft issue, the drag link, which connects the steering gear to the front axle, can fail and allow its ball socket to separate. When that happens, the steering wheel no longer controls the front wheels and the driver has no way to steer the truck. Both of these conditions pose serious crash risk at any speed on any road type.
On the electrical side, the wiring harness connected to the chassis-mounted inverter can allow water to reach the inverter's internal components, causing an electrical short. That short can generate enough heat to start a fire in the engine or chassis area. Given the fuel loads and range these trucks typically carry, a fire that starts in the electrical system can spread quickly.
