20: Hyundai Equus
If there is one thing about Hyundai, the company will try to sell a car. There have been many awkward Hyundai models on the market, but the Equus takes the cake. The company was attempting to sell a top-of-the-line luxury sedan under the Hyundai banner. For the price, the Equus was the nicest and most luxurious sedan drivers could get (via Car Magazine).

But between reliability issues and expensive maintenance, the car couldn’t survive. Potential buyers weren’t willing to invest that kind of money into what was essentially a Hyundai. As with most luxury car brands, there is a certain amount of prestige that buyers look for. A luxury car denotes a statement, and a Hyundai doesn’t exhibit that kind of reputation.
