The 2009 Volvo VHD has 4 recalls, the most serious involving front ball joints that can corrode internally and eventually fail, causing complete loss of steering control.
The ball joints on certain trucks can allow water and contaminants past their seals, leading to corrosion and accelerated wear that progresses until the joint gives out entirely. On the braking side, trucks equipped with an air release fifth wheel have an inversion valve that can be oriented so its exhaust port faces upward, letting contaminants in and corroding the valve until it malfunctions and reduces braking performance. There is also a lighting concern on trucks fitted with snow plow lamp preparation kits: the snow plow headlights can be switched on independently of the marker and tail lamps, meaning the truck may be running with front light but no visible rear or side lighting, cutting the vehicle's visibility to other drivers. Rounding out the list is a label recall affecting trucks where the certification label may carry incorrect tire information, which can lead to overloading the vehicle.
