There are a lot of advantages to buying a used car over a new model. We deconstruct Consumer Reports‘ list of least reliable preowned autos.

When the stars align just right, sure, you’re going to get the most miles out of a brand-new car or truck. But buying used puts you at an advantage in that you’re not buying anything that hasn’t already been battle-tested.

A Hyundai that’s still chuggin’ after five years is likely to keep on chuggin’ for another five. When you buy brand-new and the car turns out to be a piece of junk, you’re the one taking the risk so that everyone else can learn from your mistakes.

But, just because a used car can survive the trip home doesn’t mean it’s going to be a great investment. Some of these cars really are reliable, others are only still running because the seller has been putting way too much money into repairs.

Some of them may be in one piece only because they’ve seen minimal use, or maybe the owner simply knows they’re sitting on a time bomb, and they’re trying to pawn it off on the next sucker before it finally goes off.

And that brings us to the main advantage of buying used: there’s plenty of material out there for you to research before you make the purchase.

And one of the best places to find out if a used car is worth its weight in scrap: Consumer Reports. So let’s take a look at…

Used Cars You Shouldn’t Buy, Says Consumer Reports

To cover every single ride Consumer Reports takes issue with would take a lot more time than you probably have, so we’re just going to cover five of Consumer Reports‘ least reliable vehicles in the SUV/minivan, sedan, pickup, compact, and electric/hybrid categories, in that order.

2008-2012 Chrysler Town & Country

Relaunched for the 2017 model year as the Chrysler Pacifica, Consumer Reports warns against buying a used Town & Country from 2008-2012, owing to high numbers of returns. These would be fifth-generation T&Cs, which ran from 2008 to 2016.

The Town & Country/Pacifica isn’t a bad vehicle, but it’s sort of hit-or-miss year-to-year. Vehicle History user reviews for the 2010 cite frequent repairs and battery issues, such as the car refusing to start or suddenly losing power.

A 2009 driver points to poor overall build quality, with latches failing to snap shut and handles falling off.

A gently used 2012 C&T can be a dependable vehicle with enough work put into it, but with the Kelley Blue Book putting these decade-old cars at around ten thousand bucks, it’s simply not worth the total costs.

If you’re buying used, avoid the fifth-generation models, and if you want to buy new, wait a couple of years to see how the new Pacifica performs before you put your money down.

2011-2014 Ford Fiesta

Ford seems to produce two types of vehicles: those that will last you a lifetime with proper maintenance, and those that will start falling apart at the seams at around fifty thousand miles.

Many of the sixth-generation Fiestas seem to fall into the latter category.

The 2011-2014 models saw a number of alarming recalls, including one that saw the doors failing to latch in about half a million Fords, and one involving leaky gas tanks.

Owners report that the transmission problems tend to start around fifty, sixty thousand miles, with Fiestas slipping out of gear and rattling at highway speeds.

Add to that, wiring problems, the radio going out, batteries dying, and so on. Essentially, people are saying that the early-2010s Fiestas live up to their reputation as a flimsy, cheap-feeling car.

2014-2016 Ram 1500

Ford’s closest competitor in the full-size pickup market has had a rocky decade. Anything from before 2010 is generally going to have a solid rating with Consumer Reports, but the 2014 and 2016 have both landed on the Do Not Buy list, while the 2012 has some serious issues with brakes and power systems.

An owner review for the 2014 cites major problems with the V8 Hemi engine chewing through parts like valve guides, pistons, and heads, requiring extensive servicing at a machine shop.

A number of reviewers have also cited poor customer support from Dodge, alleging that the company will do everything it can to avoid honoring warranties or fixing anything for free.

Your mileage may vary, you might have nothing but positive experiences with Dodge’s representatives. But you’re likely to find a lot more complaints along these lines associated with Dodge than with brands like Ford and Honda.

2012-2015 Fiat 500

Interesting bit of trivia about Fiats: they tend to be a lot more reliable than their reputation would suggest. The problem is that driving schools love Fiats. So a lot of used Fiats are retired driving school cars. That means that when you buy a used Fiat, there’s a good chance your car has been used and abused by dozens of teenagers mistaking the handbrake for the gear shift.

But, the 2012-2015 Fiat 500s are an exception, according to Consumer Reports. These ones are just plain unreliable. Suspension, brakes and electronic equipment are the big issues with these models.

One driver reports that their headlights burn out once every three months or so.

If you’re shopping for a hip little city car, give Fiat a chance, just not these ones.

2016 Tesla Model X

No surprise seeing a Tesla on here. Developers have made great strides, but all-electric cars are still, largely, uncharted territory. Consumer Reports singles out the 2016 Model X for being just generally unreliable all around.

A host of electronic kinks like fidgety instrument clusters and no storage space for music make the “car of the future” a bit of a disappointment.

A number of drivers have noted a general flimsiness to the car’s design.

For instance, the falcon-wing doors don’t always latch, the wimpy suspension may leave your car dragging on the street, and the propulsion system might just drop out on you when you need it most, according to complaints registered with the NHTSA.

If you’ve absolutely gotta have a Model X, skip the 2016. Go one year up or one year back.

Your Best Bet: Research Vehicle’s Reliability

Some “reliable” cars go about 20,000 miles before the transmission goes out. Some “unreliable” cars wind up being passed down from generation to generation. “Reliable” is never a guarantee, so do your research, but don’t forget to test-drive and kick the tires before you buy.

There’s always more to learn. This list is by no means a comprehensive, all-inclusive catalog of every unreliable car ever manufactured, so our advice is to keep reading. Every second spent doing your research is a dollar saved on eventual repairs.

Frequently Asked Questions

Apr 7, 2022

What used cars to avoid?

When you are looking at used cars some stand out as the best, and some stand out as the worst. Some American cars that you should avoid include the 2008 through 2011 Buick Enclave, the 2008 Cadillac CTS, and 2013 through 2014 Chrysler 300. All of these cars score low on overall reliability ratings and have higher average annual maintenance and service costs.

Some foreign cars that you should avoid include the 2013 Kia Sportage, the 2009 BMW 1 Series, the Jaguar F-Pace from 2017, and 2009 through 2011 Audi A4. These again all score low in terms of reliability and are known to have various engine and transmission problems.

Typically cars that were built around 2008 through 2010 tend to have some of the lowest overall quality ratings. This was during a global recession and it led to some manufacturing problems that make these cars ones that you should avoid.

Can you return a used car if it has problems?

Whether or not you can return a used car depends on many factors. Most used cars are sold "as is", meaning that you are accepting the car as it is on the lot. Some used vehicles are sold with time in the manufacturer's warranty remaining on them, and some get an extended warranty. These warranties cover components but it does not mean that you can return the entire car.

Cars generally are only able to be returned when they fall into a lemon law situation. The requirements for this vary by state, but usually, the car has to have been in the shop a certain number of days during the first few months of ownership. Typically lemon laws only apply to new cars, but it is possible to buy a used car that was bought back by a dealer under a lemon law case. If a dealer does not disclose that to you then they may have to buy it back again. Handling returns under lemon law is best left to lawyers though, so you will want to contact one to figure out the laws in your area if you suspect you bought a lemon.

Some dealers offer a money-back guarantee for a certain number of days. It is a good idea to check with the store to see what their return policies are in case you are not happy with your car.

How many miles is too many for a used car?

It is always a good rule of thumb to try to buy used cars that have under 100,000 miles on them. When a car reaches 100,000 miles there are more expensive services that need to be done on them, and some of the components start to reach the end of their expected lives and will need to be replaced.

When owners do not take care of the services that need to be done at 100,000 miles it leads to them being significantly less reliable. Nowadays cars do last longer than they did in the past, but they still need to be taken care of. If you do find something you want with 100,000 miles it is a good idea to have the vehicle inspected to make sure that none of the higher mileage maintenance has been deferred.

There are some vehicles, like diesel trucks, where 100,000 miles is still early in their expected lifespan, but even these will have other components that start to wear out like alternators, starters, and A/C components. Buying a car with 100,000 miles or more may be cheaper initially, but can cost you much more in the long run.

2011 Ford Fiesta. Save yourself and buy something else.
I feel like I bought a lemon. My car has had transmission problems since day 1. I had a factory recall on the transmission and it took me over 4 years and multiple visits to ford to get it fixed and it still doesn't drive great. My safety locks on the doors failed. When I took it in I was told that was also a recall no one informed me about. And the handle to my drivers side door snapped off in my hand when I was closing my door at the gas station the other day. The door is made out of cheap plastic.

Great amount of space inside 2011 Chrysler Town & Country Touring.
We've had to replace the alternator (2x), television console, the fans, the battery (5x already), and the radio. The automatic doors have made it easy for school drop off and pick up. The legroom is awesome but that's the only things I've enjoyed. We have had bad luck with it being a reliable car as the battery light comes on within 5 minutes of driving and no one can figure out the reason.

2011 Ford Fiesta SE. Bad ac. Bad in winter. Poor hill assistance.
This car always has engine problems, it is terrible in winter, the ac does not work and seems to not be fixable. I have tried to have it fixed several times. It does not go up hills very easily, struggles often. Heat settings are not great, 1 is not enough and you cannot feel any heat and 2 makes the car a sauna.

2009 Chrysler Town & Country is a good family vehicle with lots of space for children and groceries.
The space is nice but I have had so many problems with mine. Handles falling off the back slide doors, tailgate will not latch anymore, tire sensors went bad, hard on brakes, wheel bearings wear out quickly. Decent on gas but could be much better, plenty of room for a big family and lots of groceries.

2014 Ram 1500 Big Horn Engine reliability!
Let me get this straight, nobody is talking about the hemi engine eating valve guides, destroying heads, and pistons? I have been to a established machine shop here in Houston. They have shown me many hemi engines that have had dropped and broken valve guides! Which in turn destroys engines!

2014 FIAT 500 Pop is poorly constructed.
The quality of the car is just poor. Before 75,000 miles both door handles snapped off, the arm rest snapped, the window regulator broke. The interior fabric wears away so quickly. The reliability of the car is okay, I have only had to replace one part in the vehicle ($600 with labor).

Maybe to stay away from the type of engine that is in our 2012 Chrysler Town & Country.
I love the way it drives and all the bells and whistles on the van. We had engine trouble this summer and actually just had the engine replaced. The engine was replaced by Chrysler, so we didn't have to pay anything for that repair. We also had other repairs (O2 sensors) this summer.

The 2010 Chrysler Town & Country is a minivan with seating for 7.
The transmission had to be replaced 3 times - luckily by the manufacturer. I have to have brakes replaced several times per year. It started shutting off on me multiple times until I figured out that the egr valve needed to be replaced and found someone to do that for me.

Feel like I have a lemon for a 2008 Chrysler Town & Country.
Ever since I purchased this van, it has had problems. Doors not sliding, molding falling off around the doors, water coming from the sunroof, malfunction indicator light constantly on. Tire pressure always coming on even when the tires have plenty of air. Disappointed.

Do not buy a 2012 Chrysler Town & Country.
Love the stow and go seating, and the rear view seating. Have had issues with transmission and the engine since day 1 after buying it. Tire pressure sensor has been replaced and still is not working properly. It thinks I constantly have low tire pressure when I do not.

2011 Ford Fiesta SE vs transmissions.
The transmission is jumpy and faulty. It has great gas mileage even though it is jumpy. It is comfortable and fun. When I first got it, I had to take it to the ford dealership and they had it for nearly 4 weeks, trying to reset it and get a new transmission for it.

2016 Tesla Model X 90D
In town I'll get about 70-75% of the range indicated between charges; and On the highway I get about 85-90%. I typically drive 90-110km/hr, or about the speed limit; I typically have the AC off, windows closed and we live in a moderate climate.
