This investigation was opened after ODI received a complaint from a school bus fleet stating they had experienced warning lamps failing upon opening the front entrance door. After completing their evaluation, Daimler Trucks North America, the parent company of Freightliner and Thomas Built Buses, decided to conduct a safety recall to replace the reed switch on the front entrance door with a more robust switch. All repairs will be made by Thomas Built Buses dealers and direct warranty customers. The action taken by Daimler and Thomas Built Buses resolves this investigation. Accordingly, this investigation is closed.
