The 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.
The 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.
The 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.
Notes
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.
A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
