Defect
On vehicles equipped with an automatic transmission, the clutch control program in the transmission control unit is incorrect. When range signal noise is detected while driving in D range (including manual mode), unintended clutch control may activate. This produces a deceleration shock and, in the worst case, may compromise driving stability.
Corrective action
On all vehicles, reprogram the transmission control unit clutch control program with the corrected software.
