23 Acura RLX

via Autoguide

The Acura RLX still averages more than $20,000 when looking for used models. For that much, one would expect a bit more from a luxury brand. The RLX receives poor ratings, with complaints ranging from cheap interior materials which often break or blemish easily to the overly stiff, uncomfortable ride.

Additionally, this large luxury sedan rates poorly in reliability. The Acura RLX has more than 20 complaints across seven model years that solidify it firmly on the bottom of Acura's lineup. Further, a FWD setup and uninspired handling limit the quality V6 under the hood. When an RLX comes up for sale, run away fast!

22 Hyundai Tiburon GT

Despite looking pretty cool, there isn't any saving the Tiburon. Hyundai's sporty coupe can be found at an excellent bargain of less than $3,000, but what you get in exchange may be worse than flushing that cash instead! The V6 powering the Tiburon is only good for 176 horsepower, which is significantly underpowered!

Further, the Tiburon GT is one of the most unreliable models ever, with more than 68 complaints spanning the 12 model years it existed. Many of these complaints surround the clutch and body components. Do yourself a favor and pass on the Hyundai Tiburon GT.

SUVs have been taking over roadways, leaving many beautiful sports cars in the dust bin of history. While many manufacturers have given new life to old sports cars, what Mitsubishi did with the Eclipse Cross is just insulting. For the average $25,000 you will pay for an Eclipse Cross, you can get a much better SUV. Critics complain about ride comfort, handling even cargo space!

Despite the SUV craze, there are several to avoid, and that extends to the Mitsubishi Eclipse Cross. Further, the estimated repair costs within the first few years are expected to exceed $7,000! Not really a budget option for those looking to save some money on a used one.

It is tough to narrow down to a model or a year because the Fiat 500 has been pretty consistently unreliable. Car and Driver gave the new model a 2.5-star rating. Despite the price being dropped to $15,990 in 2017 in a bid to keep consumers hooked, AutoExpress still criticized the basic specs that are available on entry models.

According to a study conducted by J.D Power in 2016, there were 127 problems reported for every 100 new Mini Coopers sold. This is a worrying statistic for anyone who wants to buy a used Mini Cooper. According to Consumer Affairs, the most common problems reported with the Mini Cooper include body integrity, cooling system, engine cooling, minor and major engine problems.

According to Consumer Reports, there are over 17 known significant issues with the Mini Cooper. The car might be inexpensive, but the costs of maintaining it are likely to become unbearable in the long run. You should at least stay away from the first and second-year models if you do insist on buying a used Mini Cooper.

The Mercedes-Benz GL was first launched in 2006. It was meant to compete in the luxury SUV segment, though many observers felt it was late to the party. According to Wikipedia, it was the first German 3-row 7-passenger vehicle to be available in the United States.

According to Repair Pal, one of the most common problems with the Mercedes-Benz GL is that the shifting starts to get rough after only a few years of use. The brake pads and rotors are made of soft materials and will need replacing after roughly every 10,000 miles. Another problem that has been reported by several owners of the car on Repair Pal is oil leakage from the vent housing. The car doesn't come cheap, even for a used one, which is another reason why you should probably avoid it.

The Dodge Nitro was on the assembly line from 2007 until 2012. According to Wikipedia, the Nitro shared the same platform with the Dodge Liberty. Jalopnik noted that the Dodge Nitro shared a couple of crippling problems with some of its Chrysler cousins.

The two major problems with the vehicle are an underwhelming interior and a below-par powertrain. Under the hood is a 3.7-liter V6 engine that can produce up to 210HP. The first year was great for the car, as Dodge was able to sell 70,000 units, but sales started dropping by 20,000 every year until it was no longer viable to produce the car.

The Jaguar S-Type was produced from 1999 to 2007. Some might see finding a good condition used S-Type for sale as the perfect opportunity to finally own a Jaguar. For others, the car has a dated exterior which can be off-putting. There are also cramped rear seats, which is not an ideal vehicle for families.

According to Jaguar Forum, there have been 212 reported problems per 100 cars, though they admitted that the sample size might be small, which is reasonable considering that the car is no longer in production. If you buy a used Jaguar S-Type, you should be ready to take it to the garage at least a couple of times per year.

You've probably seen memes of people making fun of the Chrysler Town & Country. The car was first introduced to the mass market in 1990 and was in production right up until 2016. It is estimated that there were 12 million copies of the Chrysler Town & Country sold when it was in production.

The fact that it is possible to find these vehicles for a low price might be a tempting enough reason to buy one, but keep in mind that the car received a 1.5-star rating on Consumer Affairs with a myriad of problems reported. The main one seemingly being with the transmission. There was even one reviewer who claimed that he had to call 911 because his Chrysler Town & Country caught fire with flames shooting out from under the passenger door.

Chrysler, it seems, has a quality issue with some of their cars. The Chrysler PT Cruiser was on the assembly line from 2000 until 2010. The car had a unique exterior design and was a dramatic departure from the standard Chrysler exterior.

It wouldn't be wise to go for the early models, no matter how affordable they are. According to Insurance Institute For Highway Safety, the 2008 Chrysler PT Cruiser did not offer even the standard safety features that were available even in small cars at that time.

The truck is also underpowered and might not be the best choice if you are looking for something punchy.
