Defect: ARBOC Specialty Vehicles, LLC (ARBOC) is recalling certain 2018-2021 Spirit of Equess buses equipped with Cummins Westport Inc. B6.7N natural gas 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.
Fix: ARBOC will work with the engine manufacturer, Cummins, Inc., to notify owners, and Cummins dealers will recalibrate the engine control module, free of charge. The recall began April 5, 2021. Owners may contact ARBOC customer service at 1-866-953-5555.
