10: Chrysler 300M
Another sedan that suffered from a treasure trove of reliability problems was the Chrysler 300M. Chrysler marketed the 300M as a sport sedan, but in reality, it was your run-of-the-mill Intrepid. Its lousy engine designs were the main thing that hampered the 300M. With competition from more experienced automakers, it was hard to justify the cost of a 300M (via Motor Trend).

Chrysler would replace the 300M in 2005 with the 300C. The latter was a much better car through and through. The cab-forward sedans Chrysler tried to force-feed consumers during the 1990s will go down as notorious lemons. There were much better options drivers could get during this era of automotive design.
