Complaints of the inability to shift gears on some 2011-2012 Ford Mustangs, equipped with six speed manual transmissions, has lead the National Highway Traffic Safety Administration (NHTSA) to open an investigation to see if the sports car should be recalled. Erratic shifting behavior while merging into traffic or turning left across oncoming traffic, were reported to have caused near collisions with other vehicles on the road. The NHTSA’s preliminary evaluation will assess the scope, frequency and potential safety consequences associated with the alleged defect. If the investigation should lead to a recall, almost 30, 000 2011-2012 Ford Mustangs could be recalled.
