Volvo VNL Recall 15V634: Auxiliary power unit may detach from truck, creating crash risk

NHTSA campaign 15V634, reported October 8, 2015, 101 vehicles potentially affected.

What this recall means for you

Certain Volvo VNL trucks built between December 2011 and September 2013 may have an electric auxiliary power unit (APU) with a metal housing whose mounting points can crack and tear. The mounting bolts holding the power unit can also loosen or fail. If this happens, the unit could detach from the truck and become a road hazard, increasing the risk of a crash.

Volvo will notify affected owners. An authorized IFS dealer will inspect the APU for damage and, where needed, install a welded gusset upgrade kit to strengthen the APU C-channels. All units will also receive stronger clamping brackets. The repair is free. Owners can contact Volvo customer service at 1-800-528-6586 or IFS customer service at 1-920-206-9333, and can check their VIN for open recalls.
