The National Highway Traffic Safety Administration’s Office of Defects Investigation is opening a “Preliminary Evaluation” regarding reports of 2015-2017 Ford F-150 trucks suddenly downshifting while moving at “highway speeds.”
“The Office of Defects Investigation (ODI) has received 138 consumer complaints for model years 2015-2017 Ford F-150 vehicles alleging an unexpected, unrequested transmission downshift to a lower gear while traveling at highway speeds without any prior warning or driver input,” the announcement on the NHTSA website notes.
“This unrequested transmission downshift would cause unexpected rapid vehicle deceleration. Certain consumer complaints additionally allege that the vehicle’s rear wheels temporarily lock, seize, and/or skid during the downshift resulting in a loss of vehicle control increasing the risk for crash and injury.”
