Vapor Bus International (Vapor Bus) is recalling certain ETO Controller Assemblies, part number 51220550, manufactured March 7, 2013, to April 12, 2015. These assemblies, which control the door operator motor and brake, may have a software defect which can cause the rear passenger doors to open, without warning, when the bus accelerates from a stopped position.
If the rear bus door opens while the bus is in motion, there is an increased risk of injury for the passengers.
Vapor Bus has notified the bus manufacturers that purchased the affected units, and dealers will update the ETO Controller Assembly software, free of charge. The recall began on May 8, 2015. Owners may contact Vapor Bus customer service at 1-847-777-6450.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
