Quality vans is recalling certain model year 2004 through 2006 vans equipped with ricon platform style wheelchair lifts. These vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard no. 404, "platform lift installations in 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.
