Comm trans is recalling 108 MY 2005-2008 Ford E250 and E350 vans built on Ford chassis and equipped with ricon platform style wheelchair lifts. These lifts fail to comply with the requirements of Federal Motor Vehicle Safety Standard no. 403, "platform lift system accessible for motor vehicles." The anti-stow interlock may not detect the presence of a wheelchair or mobility aid user. The pressure sensing switch that detects the presence of weight on the platform was not adjusted to the necessary sensitivity level. The lift could stow even though someone or something is still on the lift.
