The 2021 Volvo VN has 3 recalls, the most serious affecting trucks with a Cummins X15d engine, where a software fault can invert the throttle signal and prevent the engine from returning to idle, raising the risk of a crash.
The passenger side bench seat may not be securely attached to the floor on certain trucks, meaning the seat can shift during a crash and increase injury risk to any passenger seated there. There is also an electrical issue where interference on the power line can cause the Bendix electronic control unit to misprocess commands or stop functioning entirely, which can reduce or disable safety systems including anti-lock brakes, automatic traction control, electronic stability control, adaptive cruise control, and collision mitigation.
