Defect
Daimler Trucks North America, LLC (DTNA) is recalling certain 2021 Thomas Built Saf-T-Liner C2 Jouley electric school buses.

Safety risk
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.
Remedy
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.
