19: 1971 Ford Pinto
Likewise, the Ford Pinto itself also had an issue proving customer satisfaction. After a brief period of controversy due to a rear hatch design flaw, the Pinto saw a dramatic sales decline as well. Sadly, the platform was one of the most potentially good ones to come out of Detroit around this period (via Tort Museum).
The AMC brand was seeing a rapid decline and GM was also having troubles adapting to the new emissions regulations. If you were a gear head around the 1970s, you were being let down left and right by automakers. Ford just couldn’t catch a break with the Pinto.
