ODI opened this investigation upon learning of two incidents where the wheel chair assembly broke through the side door while the motor coach was being operated. Both incidents resulted in property damage to parked vehicles.After further review, MCI decided to conduct a safety recall to resolve this issue. MCI will provide parts and labor to install a Ricon-designed retrofit kit that includes a spring-loaded lock mechanism. The additional lock mechanism will prevent unintended wheel chair lift deployment regardless of the cause. The population includes 1995 through 2009 D4000's, 1997 through 2010 D4500's, and 2005 through 2010 D4505 models. This resolves all issues concerning this investigation. This investigation is closed.
