Vapor Bus International (Vapor Bus) is recalling certain Electric Transit Operator (ETO) Controller Assemblies, part number 51220550, manufactured March 7, 2013, to December 21, 2015. These assemblies, which control a bus door operator motor and brake, may have a software defect which can cause failure of the rear door guide roller linkage resulting in a bus' rear door opening unexpectedly while the bus is in motion.
If the rear bus door opens expectedly while the bus is in motion, there is an increased risk of injury for the passengers.
Vapor Bus will notify owners, and dealers will update the ETO Controller Assembly software, and replace all of the roller brackets, free of charge. The recall began on April 12, 2016. Owners may contact Vapor Bus customer service at 1-847-777-6423.
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.
