Thomas Built Buses Saf-T-Liner C2 Recall 17V217: Bus Brake May Stay Engaged on Slippery Roads, Raising Crash Risk

NHTSA campaign 17V217, reported March 29, 2017, 1 vehicles potentially affected.

What this recall means for you

On certain 2016 Thomas Built Buses Saf-T-Liner C2 school buses with an 8.0L propane engine and an Allison transmission, the transmission grade brake may not release when the disable switch is pressed. In icy or other slippery conditions, aggressive downshifting can then cause a loss of traction.

If the transmission grade brake stays engaged without the operator knowing, the risk of a crash increases. Owners should take this seriously, especially if the bus is driven in winter or wet conditions.

The repair is free. Daimler Trucks North America will notify owners, and an authorized dealer will update the bus's programming at no charge. Contact DTNA customer service at 1-800-547-0712 and reference recall FL-734. You can also check your vehicle identification number (VIN) for any open recalls.
