Thomas Built Buses recall: Parking brake
What is wrong
Daimler Trucks North America, LLC (DTNA) is recalling certain 2021 Thomas Built Saf-T-Liner C2 Jouley electric school buses. If the service brake pedal is pressed and then released while the parking brake is engaged, the parking brake may release unexpectedly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."
What could happen
An unexpected disengagement of the parking brake without continual application of the service brake may allow the vehicle to roll freely, increasing the risk of a vehicle crash.
The fix
DTNA will notify owners, and dealers will update the electronic control unit (ECU) software, free of charge. The recall began January 22, 2021. Owners may contact DTNA customer service at 1-800-745-8000. DTNA's number for this recall is FL-870.
