The 2015 Volvo VNL has 9 recalls, the most serious involving multiple issues that can cause loss of steering control, engine stall while driving, or wheel-end fires and tire blowouts from brake system problems.
Two recalls address front axle integrity: on certain trucks, the front steer axle beam can break and cause a complete loss of steering. A separate recall covers front axles equipped with Meritor FF967 Non-Drive units, where reduced beam strength can also lead to fracture and loss of vehicle control. On the brake side, a trailer hand brake handle that sticks in the on position can cause the trailer brakes to drag, overheating the wheel end and potentially starting a fire or blowing a tire. Brake chamber diaphragms that are not properly seated can cause similar overheating or trigger an unintended spring brake application. Air brake actuator diaphragms on some trucks can also leak internally, trapping pressure in the parking brake section. Separate software issues round out the list: a D16-equipped engine can stall while driving due to an incorrect engine control unit parameter, and incorrect software managing the electronic air dryer can allow oil and water to contaminate the air brake system, reducing braking performance. On certain natural gas-engine trucks, condensation in the intake manifold can freeze in cold weather and cause elevated exhaust temperatures or flames from the exhaust pipe. There is also a concern on trucks equipped with enhanced cruise control and no side fairings, where the automatic emergency braking feature can disable itself without warning.
