Toyota made unintended acceleration famous, but Audi was into it way before Toyota. In the 1980s, the Audi 5000 was outta here (even if it didn't mean to be). The driver would shift out of park and plan on easing out of the driveway or parking space like a regular, well-adjusted human being normally would — and that's when the car would take off on its own. And just like Toyota, it took some time to get this one right. Audi recalled the cars three times, in 1982, 1983, and 1987, before getting it right. Or maybe they just threw in the towel — Audi stopped selling the 5000 in the United States in 1988. Eh, only 389,102 cars were affected by the problem, anyway.
