40: Chrysler Sebring
The Sebring Convertible is one of the best-selling Chrysler models of all time. The Sebring sedan, on the other hand, is a car that most would rather forget. It was universally panned for cheap build quality and questionable reliability, which led to the car being a rental fleet staple (via Car & Driver).
The Sebring had decent looks and a seemingly upscale interior for the price, but the quality issues all overshadowed it. Sales for the car never really recovered, and Chrysler would take one more jab at the car segment with the 200 until the company finally gave up.
