21V120000
What was wrong
Defect
Daimler Trucks North America, LLC (DTNA) is recalling certain 2019-2021 Thomas Built Buses Saf-T-Liner C2 school buses equipped with Cummins B6.7N engines. The engine control module software may be calibrated incorrectly, causing the engine to not limit engine speed or torque as intended for certain safety-related functions such as vehicle braking, traction and stability control, speed control, or collision avoidance.
Risk
If safety-related functions such as vehicle braking, stability, speed, and collision avoidance do not function properly, it can increase the risk of a crash.
Manufacturer remedy
DTNA will work with the engine manufacturer Cummins Inc. to notify owners, and Cummins dealers will recalibrate the engine control module, free of charge. Owner notifications were mailed on March 29, 2021. Owners may contact DTNA customer service at 1-800-547-0712. DTNA number for this recall is FL-879.
