Certain 2020-2021 Model Year Transit Vehicles Equipped with 3.5L PFDI Engines Inactive Smart Acceleration Truncation Feature In all of the affected vehicles, the Smart Acceleration Truncation (SAT) feature is non-functional. The SAT feature is intended to provide common performance for an empty vehicle as would be expected for a fully loaded vehicle. The feature restricts the acceleration capability for empty vehicles where drivers utilize significant accelerator pedal input. When the SAT feature is non-functional, drivers who reach elevated torque/acceleration rates will not see the desired torque de-rate that the feature is expected to deliver. |
