Daimler Trucks North America LLC (DTNA) is recalling one model year 2016 Thomas Built Buses Saf-T-Liner C2 school bus equipped with an 8.0L propane engine and an Allison transmission. The transmission grade brake on this bus may not deactivate when the disable switch is depressed, which can cause a loss of traction in certain icy, or other slippery conditions, due to aggressive downshifting.
If the transmission grade brake stays engaged, unknowingly to the operator, in low-traction conditions, it can increase the risk of a crash.
DTNA will notify the owner, and a dealer will update the bus' programming, free of charge. The recall began on May 26, 2017. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-734.
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.
