2011 VOLVO VAH

TRAILER HITCHES:FIFTH WHEEL ASSEMBLY

Volvo Trucks North America (Volvo) is recalling certain model year 2011-2013 VNL and VNM trucks manufactured June 21, 2010, to December 14, 2012. The affected trucks are equipped with Fontaine Ultra LT Fifth Wheel connectors, which, due to cumulative damage to the fifth wheel and its locking mechanism, have a locking mechanism that may fail to operate or to properly engage.

Risk: If the fifth wheel and locking mechanism are sufficiently damaged, the locking mechanism may fail to operate as intended and the trailer may unexpectedly detach from the tractor, increasing the risk of a crash.

TIRES

Volvo Trucks North America (Volvo) is recalling certain model year 2011-2014 VAH and VNL trucks manufactured May 12, 2010, to October 31, 2014. The affected vehicles may experience premature tire failure during certain operating conditions such as high speeds, heavy load, and high road temperature.

Risk: Premature tire failure could increase the risk of a vehicle crash.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM

Fontaine Modification (Fontaine) is recalling certain model year 2011-2013 Volvo VAH vehicles modified with upward facing exhaust diffusers for use as auto-haulers. In the affected vehicles, heat from the exhaust may transfer to the roof of the truck cab and/or the vehicles above the cab.

Risk: Excessive heat could result in a fire.

POWER TRAIN:CLUTCH ASSEMBLY

Volvo Trucks North America (Volvo) is recalling certain model year 2007-2014 VAH, VHD, VNL, VNM, and VT models. The affected vehicles were built without a redundant clutch disengagement switch. Without a redundant switch, a loss of signal from the brake air pressure switch can prevent the clutch from automatically disengaging when the brake is applied.

Risk: Without a signal to disengage the clutch when the brakes are applied, the distance required to stop the truck may lengthen, increasing the risk of a crash.
