The largest auto recall occurred in early 1981, when the Ford Motor Company announced the recall of 21 million Ford, Lincoln, and Mercury vehicles from the 1970 through 1980 model years. The recalled vehicles contained defective parking gear that could fail to engage after the vehicle was shifted to park, often leaving the car in reverse. Instead of issuing repairs, Ford provided car owners with a dashboard sticker warning them to set the parking brake and shut off the ignition before exiting the car, lest “unexpected and possibly sudden vehicle movement” occurs.
At the time of recall, the U.S. Department of Transportation had linked the malfunctioning parking gear to 6,000 accidents resulting in 98 fatalities and 1,710 injuries.
