There’s no bigger nightmare than owning a car which spends more time at the mechanics than on the road. Reliability is one of the key factors when choosing a both used or a new car, so when you are looking for a daily driver, it should definitely be among your most important criteria. So, today, we will address some of the least reliable cars on the used market. Of course, we’re not going to include supercars and other performance cars of the sort, because those machines weren’t made for everyday commutes, and their maintenance routines are completely different. So, here we go!

Range Rover

While Land Rover’s luxurious off-roader is among the best for conquering trails, many electrical components and expensive maintenance costs put it on our list of the least reliable cars out there. In addition to electrical problems, a vast number of Range Rovers also suffered from axle and suspension issues. Given that the Range Rover has fantastic off-road abilities when it works properly, these faults seem a bit ironic, don’t they? Repair bills for a car like this are likely to be very costly even for lesser breakdowns, so you should probably avoid it unless you have a Land Rover approved warranty.

Mini Cooper

It seems like Mini can’t keep up with the rest of the pack when it comes to reliability. Many consumers have reported a wide array of problems, ranging from ignition coil failures to fuel tank leaks and various engine issues. As the list will show, many unreliable cars tend to be more expensive to buy new and filled with electronics and complicated systems, so the Mini should be quite reliable as it doesn’t fit the mold. On contrary, it is one of the least reliable used cars out there, so you should definitely avoid it despite its charm.

Mercedes-Benz SL

The 2000s Mercedes-Benz SL is among the most complicated cars of the era with features like a 6.0-liter V12 engine and electric hard top as its defining selling points. These “wow factor” dream features for most are a nightmare for used buyers! As a used car, the SL proved to be quite problematic, with V12 engines suffering from eye wateringly expensive reliability issues. V8-powered versions are a bit more reliable, but whatever goes wrong, you’ll be faced with very expensive (4 Figure) bills. Ouch.

Mercedes-Benz CL

To continue on with the three-pointed star, the Mercedes-Benz CL was also a technological marvel back when it was new, but today, it is one of the least reliable used luxury cars. As with the SL, the CL should be avoided with the 6.0 liter V12, but you should expect it to suffer from electronics issues too. The repair costs are also astronomical, so if you really want one, make sure to pay extra bucks for recently serviced examples. Do NOT buy this car thinking it will be cheap. You will be wishing you hadn’t before long.

Audi A6 Allroad

Audi is generally among the most trustworthy brands worldwide, with cars like the A4 and the A6 topping many reliability tests as winners in their respective classes. On the other hand, the lifted and beefed up A6 Allroad is one of the least reliable used cars, likely due to the increased complexity of the model. The beefed up ride height of the Allroad required complex air suspension and I’m sure you can guess what happens to that when it gets old! As well as this is, its likely that the Allroad gets subjected to various degrees of abuse that the usual A6 cars weren’t, in short, basically people offroading a car that really shouldn’t be offroaded!

Tesla Model X

Even though Teslas are regarded as the peak of technology when it comes to cars, this electric-powered family car hasn’t been able to deliver in the reliability department. As with any brand new company or technology, you’re probably not going to get the best product they will ever make. Some flaws include faulty bodies, bad paint quality and faulty aircon system. If you bought the car new, you’re going to be fine as Tesla warranties are great. If you’re buying one used without an official warranty, Stay the heck away! Sure, a few rough edges doesn’t sound like much of a flaw but wait until these cars to get a bit older. Then, the real fun should start when all other flaws come to the surface. We cant blame anyone for these issues. Elon Musk and Telsa have done amazingly well in pushing the tech forward, but as with all new tech, first versions are rarely perfect!

Porsche 911

The claim that the Porsche 911 can be unreliable is a controversial one, but hear us out. Yes, it is a reliable car compared to others in the class, but it can still suffer from many reliability issues. In all honesty, many of them are related to neglecting regular maintenance, because even the simplest routine checks can be very costly. As Porsches age, the subsequent owners tend to skip these expensive procedures, and when something breaks down, the bills keep getting higher. Some 911s suffer from rod bearing issues, but increasingly for the 996 generation rust is now becoming an issue. Because of this, you should remember that there is no such thing as a cheap Porsche. I would buy one with an official warranty or perhaps get to know your local Porsche specialist first!
