17: Chrysler Sebring (2007)
The Chrysler Sebring Convertible was a strong seller for Chrysler for several years. The Sebring sedan, on the other hand, was not. A car often relegated to rental car lots, the Sebring was about as barebones as you could get. The design was cheaply made with lots of hard plastics and an underpowered engine.

Wrap this in a semi-upscale design and you have what amounts to one of the worst-designed cars on the road. The 2.7L V6 is largely considered the worst engine Chrysler has ever made with reliability issues and lawsuits pending to this day. This incarnation of the Sebring sedan was as bad as you could get and it’s no wonder it didn’t sell.
