Used Cars to Avoid in 2026: 20 Models With High Repair Costs

The used cars to avoid in 2026 are models with known, expensive engine and transmission failures, such as the 2011 to 2015 Jeep Grand Cherokee, the 2016 to 2018 Hyundai Tucson and the 2012 to 2018 Ford Focus. Most major engine and transmission repairs on this list cost $2,500 to $6,500, which can be more than the car is worth.

That cheap listing for a five-year-old luxury sedan at half its original price may be cheap for a reason. Below are 20 used cars to skip, the problem behind each one, what the repair usually costs, and what to check if you still want to buy. If you would rather start with safer picks, look at reliable, affordable vehicles with proven track records.

How We Chose These 20 Used Cars to Avoid

Every car on this list has at least one of three traits:

• A known weak point in an expensive part, usually the transmission, engine, timing chain or head gasket.
• Failures that show up early, often before 100,000 miles and sometimes much sooner.
• Repair bills close to the car's value, so one failure can turn a cheap car into a total loss.

Model years matter. Many of these cars were fixed in later years, so the years in each heading are the ones to watch, not the whole model line.

Quick List: Problems and Repair Costs by Model

Use this table to check a listing fast. The full breakdown for each model follows below.

The 20 Used Cars to Avoid, Model by Model

Each entry covers the problem, the typical repair cost and what to do if you are looking at one or already own one.

1. Jeep Grand Cherokee (2011-2015)

The Problem: Transmission failure is practically a rite of passage for these Jeeps. The 8-speed automatic transmission was new and, frankly, not ready for prime time. Owners report harsh shifting, slipping between gears, and catastrophic failures as early as 80,000 miles.

The Cost: Transmission replacement runs $3,500 to $4,500. If you catch it early, software updates might help temporarily, but you're usually just delaying the inevitable.

What to Do: Ask for proof of any transmission software updates and fluid service, and feel for harsh or slipping shifts on the test drive. If you already own one, budget for a transmission replacement rather than hoping it lasts.

2. Dodge Charger (2011-2014)

The Problem: The 2.7L V6 engine in these models develops oil sludge buildup, leading to premature wear. Valve train problems, oil leaks, and catastrophic engine failure aren't uncommon by 100,000 miles. The transmission also loves to fail, independently or in concert with engine problems.

The Cost: Engine replacement: $4,000 to $5,500. Transmission work: $3,000 to $4,000. Some owners have had to do both.

What to Do: Get a pre-purchase inspection from someone who knows Dodge engines. If you own one, use full synthetic oil and change it every 3,000 miles.

3. Hyundai Tucson (2016-2018)

The Problem: The Theta II engines in the 2016 to 2018 Tucson are prone to early bearing wear and metal debris in the oil. Earlier 2010 to 2012 models largely avoided this engine. Our Hyundai Tucson and Santa Fe problems by year guide has the recall details. Hyundai has issued multiple recalls, but many owners still experience engine seizure without warning. Some have had engines fail at 60,000 miles.

The Cost: Engine replacement: $4,500 to $6,500. This is one where you might face a total loss because repair costs approach vehicle value.

What to Do: If you own one, keep meticulous maintenance records and watch your oil pressure gauge like a hawk. Consider an extended warranty before you buy.

4. Ford Focus (2012-2018)

The Problem: The dual-clutch automatic transmission is the main weak point. Shuddering, jerky acceleration, delayed response, and complete transmission failure plague these cars. Some owners report issues at 30,000 miles.

The Cost: Transmission replacement: $3,200 to $4,800.

What to Do: Test drive carefully and feel for transmission hesitation. If you own one, document everything for warranty claims. Ford extended coverage on some model years, so check your specific VIN.

5. Jeep Wrangler (2007-2011)

The Problem: The 3.8L V6 engine is prone to piston slap and early failure. Additionally, transfer case and automatic transmission issues plague this generation. Paint also peels like nobody's business, which is just adding insult to injury.

The Cost: Engine replacement: $3,800 to $5,200. Transfer case: $2,500 to $3,500.

What to Do: If you are set on a used Wrangler, look at a 2015 or 2017 JK or a 2020 or newer JL, and skip the 2012 and 2013 models unless the price is heavily discounted. Our Jeep Wrangler problems by year guide covers every year.

6. BMW X5 (2007-2010)

The Problem: Carbon buildup in direct injection engines, fuel pump failures, and electronic cooling fan issues. Suspension components also wear aggressively. These are high-maintenance cars that get even more expensive in their second life.

The Cost: Engine cleaning: $1,500 to $2,500. Fuel pump: $1,000 to $1,800. Suspension repairs: $2,000 to $5,000 depending on what goes wrong.

What to Do: Unless you're comfortable with German luxury repair bills, skip it. These aren't great used buys for average buyers.

7. Nissan Altima (2007-2018)

The Problem: CVT shuddering and failure are common across these years, and the 2013 to 2018 models are the worst stretch. Engine ticking, carbon buildup and oil consumption also show up, and some owners report losing power while driving.

The Cost: Transmission: $3,000 to $4,500. Engine work: $2,000 to $3,500.

What to Do: If you want an Altima, the 2020 to 2022 models are the better buy. If you already own an older one, stay current with CVT fluid changes (yes, CVTs do have fluid). See our Nissan Altima problems and repair costs guide for each year.

8. Infiniti QX56 (2004-2010)

The Problem: Timing chain stretching and failure leads to engine rattle and eventual catastrophic damage. It is not a question of if, but when. We've also seen numerous transmission issues and suspension component failures.

The Cost: Timing chain replacement: $2,500 to $4,000. Transmission work: $3,500 to $5,000.

What to Do: Have a pre-purchase inspection focus specifically on the timing chain. Any noise from the engine should be a deal-breaker.

9. Volkswagen Passat (2012-2015)

The Problem: The turbocharged engine consumes oil at alarming rates. Timing chain tensioner failure is also possible. DSG dual-clutch transmission (in some models) exhibits shifting issues similar to the Ford Focus.

The Cost: Engine work: $2,000 to $4,000. Transmission: $3,500 to $5,000.

What to Do: If you own one, check your oil level monthly. Top it up between oil changes, and ask the seller how much oil the car uses.

10. Subaru Impreza/Outback (2009-2013)

The Problem: Head gasket failure is common in these model years. Our Subaru Outback and Forester problems by year guide reports it for nearly 40% of 2010 to 2014 Outback owners by 100,000 miles. It's a design flaw that affects even the most carefully maintained examples. You'll also see transmission problems in the automatics.

The Cost: Head gasket replacement: $2,500 to $3,500. Transmission: $2,800 to $4,200.

What to Do: If you must buy a Subaru from this era, get a pre-purchase inspection that includes a cooling system pressure test. And save up for that head gasket work. If you can stretch your budget, the 2015 and newer Outback with the FA-series engine has largely solved the gasket problem, but have the CVT inspected.

11. Mercedes-Benz C-Class (2008-2013)

The Problem: Engine carbon buildup, fuel injector problems, and thermostat housing issues create a cascade of problems. The transmission (7-speed automatic) can be problematic. Electronics also fail frequently.

The Cost: Engine service: $1,500 to $3,000. Transmission: $3,500 to $5,500. Electronics: $500 to $2,000 per issue.

What to Do: These are beautiful cars, but they're expensive to fix. Pass unless you have a good relationship with a Mercedes mechanic and deep pockets.

12. Ford Fiesta (2010-2019)

The Problem: Dual-clutch transmission issues (same as Focus), engine piston slap, and faulty door latches. This little car has big problems that come in small packages.

The Cost: Transmission: $3,200 to $4,800. Engine work: $2,000 to $3,500.

What to Do: If you're buying used, look for the manual transmission option from these years, which is more reliable.

13. Audi A4 (2009-2012)

The Problem: Carbon buildup in direct injection engines, transmission fluid issues and suspension problems. The DSG transmission can be problematic. These are complex cars with expensive parts.

The Cost: Engine service: $2,000 to $4,000. Transmission: $4,000 to $6,000. Suspension: $1,500 to $3,000.

What to Do: Unless you have a trusted Audi specialist and room in your budget for these repairs, walk away.

14. Chrysler 200 (2015-2017)

The Problem: 9-speed transmission exhibits hesitation, jerking, and complete failure. Engine oil sludge buildup. Electronics gremlins abound.

The Cost: Transmission: $4,000 to $5,500.

What to Do: This is one of the few "newer" cars on this list for a reason. It's a bad design that Chrysler hasn't fully resolved.

15. Toyota Highlander (2004-2008)

The Problem: V6 engine sludge issues and transmission failure, particularly in the automatic models. Timing belt wear (if not replaced regularly) can lead to catastrophic engine damage.

The Cost: Transmission: $3,500 to $5,000. Engine work if timing belt fails: $4,000 to $6,500.

What to Do: Verify the timing belt has been replaced before you buy. If you own one, budget for this service if it's overdue.

16. Honda Odyssey (2005-2010)

The Problem: Transmission failure is common, particularly between 80,000 and 120,000 miles. We're talking premature wear and outright failures. Engine carbon buildup can also occur.

The Cost: Transmission: $3,500 to $5,000.

What to Do: If you need a minivan, consider the 2011+ which had better transmission refinement.

17. Hyundai Elantra (2011-2016)

The Problem: Engine bearing concerns similar to the Tucson's. Premature bearing wear, metal shavings in oil, and engine seizure. Additionally, transmission issues in some automatics.

The Cost: Engine replacement: $4,500 to $6,500. Transmission: $2,800 to $4,000.

What to Do: These are cheaper cars originally, so total loss is real. Walk away from questionable examples.

18. Volkswagen Jetta (2011-2014)

The Problem: Turbo engine carbon buildup, oil consumption issues, transmission problems with the DSG variant. Electrical gremlins that are hard to diagnose.

The Cost: Engine service: $1,500 to $3,500. Transmission: $3,500 to $5,000.

What to Do: Non-turbo models are slightly better, but VW reliability from this era is suspect across the board.

19. Ford Flex (2009-2012)

The Problem: 6-speed transmission exhibits shuddering and failure. Engine sludge buildup in the 3.5L V6. Suspension component wear is aggressive due to the vehicle's weight.

The Cost: Transmission: $3,500 to $5,000. Engine service: $2,000 to $3,500.

What to Do: The later 2013+ models are better, but even then, proceed with caution on this platform.

20. Mazda3 (2004-2009)

The Problem: Transmission failure (both manual and automatic variants have issues), engine knocking, and suspension wear. These are cheaper to fix than some on this list, but failure rates are high.

The Cost: Transmission: $2,500 to $3,500. Engine work: $1,500 to $2,500.

What to Do: If you own one, keep up with maintenance religiously. These cars will reward attention but punish neglect. Want a Mazda3? The 2014 to 2017 models are on our most reliable used cars under $20,000 list.

Buying one anyway? Most repairs on this list are engine and transmission failures. A CoverageX Essential plan covers the engine, transmission and drivetrain, including seals, gaskets and turbocharger parts where they apply, and Signature adds electrical systems, air conditioning and suspension. Coverage starts after a 30-day, 1,000-mile waiting period and does not pay for problems the car already has, so set it up before trouble starts.

What to Do If You Already Own One of These Cars

If you already own one of these cars, don't panic. Not every example fails, and good care lowers the odds.

• Stay on top of maintenance. Follow the schedule in your owner's manual, use quality parts and fluids, and use synthetic oil if the manual calls for it.
• Get regular inspections. Have a trusted mechanic look the car over at least once a year so small problems get fixed before they turn into big ones.
• Check for recalls and extended factory coverage. Some makers issued recalls or extended coverage for known problems, such as Hyundai for Theta II engines and Ford for some Focus model years. Run your VIN on the maker's website.
• Consider protection before something breaks. An extended car warranty, legally a vehicle service contract, can pay for covered repairs after the waiting period. It will not cover a problem the car already has, so it only makes sense while the car runs well. Read when not to buy an extended warranty first.
• Document everything. Keep every receipt, service record and fluid change. This protects your resale value and helps if you ever file a claim.

Next Steps Before You Buy a Risky Model

1. Check the exact model year against this list and the model's guide in our vehicle reliability hub.
2. Run the VIN for open recalls and any extended factory coverage.
3. Ask for service records, with proof of transmission fluid, timing belt or chain, and cooling system work where it applies.
4. Test drive in stop-and-go traffic and at highway speed, and feel for shudder, slipping or hesitation.
5. Get a pre-purchase inspection that targets the known weak spot. It typically costs $100 to $200. Bring our used car inspection checklist.
6. If the car has more than 100,000 miles, read should you buy a used car with 100,000 miles and our guide to extended warranties for high-mileage cars.
7. Price in the risk. If the likely repair costs more than the discount, walk away.

Used Cars to Avoid: Frequently Asked Questions

How do I check whether a used car model has known problems?

Look up the exact model year, not just the model. Start with a problems-by-year guide in our vehicle reliability hub, then run the VIN for open recalls and extended factory coverage. Finally, ask a mechanic who knows the brand to inspect the known weak spots before you buy.

Should I get a pre-purchase inspection on a car from this list?

Yes. An inspection typically costs $100 to $200, which is small next to an engine or transmission repair that can run several thousand dollars. Ask the mechanic to focus on the known problem, such as a cooling system pressure test on a Subaru or a timing chain check on an Infiniti QX56. See our pre-purchase inspection checklist.

Is a higher-mileage version of a bad model ever worth buying?

Rarely. On these models the expensive failures often show up between 60,000 and 120,000 miles, so a high-mileage example has either had the repair or is close to needing it. It can make sense only if receipts prove the main repair was done, the price reflects the risk, and an inspection comes back clean.

What should I do if I already bought one of these cars?

Keep up with maintenance, have it inspected at least once a year, check the VIN for recalls and extended factory coverage, and keep every service record. If it still runs well, an extended car warranty can cover future breakdowns after the waiting period. If it already has a serious problem, see what to do if you bought a used car lemon.

Is an extended warranty worth it on an unreliable used car?

It can be, if the car runs well today and you plan to keep it. These models are known for repairs that cost several thousand dollars, and a vehicle service contract can pay for covered parts after the waiting period. It is not worth it on a cheap short-term car worth less than the plan, or if you plan to sell within 12 to 18 months. See when not to buy an extended warranty.

Will an extended warranty cover a problem my car already has?

No. Extended car warranties do not cover pre-existing problems. CoverageX plans also have a 30-day, 1,000-mile waiting period before you can make a claim, so buy coverage while the car is healthy, not after warning signs appear. An inspection before you buy tells you where the car stands.

Which used cars should I buy instead?

Look at models with a long record of low repair costs, such as the 2015 to 2018 Toyota Camry, the 2012 to 2016 Honda CR-V, the 2013 to 2018 Toyota RAV4 and the 2014 to 2017 Mazda3. Our most reliable used cars under $20,000 list covers 15 models with the best years for each.

Does a CoverageX plan cover engine and transmission failures?

Yes, for covered parts. The Essential plan covers the engine, transmission and drivetrain, including seals, gaskets and turbocharger parts where they apply. Higher plans add more systems, and Executive covers everything except the listed exclusions. Repairs are done at licensed repair shops, and CoverageX pays the shop directly. Compare Auto Protection plans.

The Bottom Line on Used Cars to Avoid

Buying used is smart, but buying a car from this list without checking it first is a gamble with your bank account. Problems are often worse in specific years, so research the exact model year and VIN. Thorough research and pre-purchase inspections are your best friends, and our guide on how to compare warranty providers and the learning center can help you decide what protection, if any, makes sense. For more, see our list of more reliable options.
