Swedish bus and truck maker AB Volvo has recalled 42,000 trucks in North America because of defective inlet pipes that could cause fires in the engine compartment. The recall, concerning Volvo’s VN and VHD models, comes after what the company said was “a number of cases of heat damage” in engine compartments as a result of inlet pipes that could crack or break. Volvo says only two cases of fires had been reported and no one was injured in those incidents. But, if these pipes are not repaired or replaced, components in the engine compartments may be exposed to hot exhaust gases, which could lead to a fire. Clearly, the risk of fire leading to injury is apparent. Volvo Trucks North America will replace any damaged parts and also install a heat shield on all trucks. It should be noted that the Swedish truckmaker is unrelated to the automaker Volvo, which is part of Ford Motor Co.
