Buying a used car can save money, but choosing the wrong one can cost you far more in repairs and frustration.

In 2026, some vehicles still stand out for the wrong reasons. Whether it’s reliability issues, expensive repairs, or known defects, these are the models buyers should approach with caution.

What Makes a Car “Bad” to Buy Used

Before jumping into specific models, it’s important to understand what makes a used car risky.

Common problems include:

  • Frequent mechanical failures
  • Expensive repairs
  • Poor long-term reliability
  • Known design flaws

A low purchase price doesn’t mean a good deal if the car constantly needs repairs.

Ford Fiesta (2011–2016 Automatic Models)

This one may look familiar.

While the Ford Fiesta is affordable and fuel-efficient, automatic models from these years are known for transmission problems.

Common issues:

  • Rough shifting
  • Delayed acceleration
  • Transmission failure

If you’re considering one, a manual version is generally a safer option.

Nissan Altima (2013–2018)

The Altima is popular, but certain years are known for transmission issues.

Common problems:

  • CVT transmission failures
  • Hesitation and slipping
  • Expensive repairs

These issues can show up even with regular maintenance.

Chevrolet Cruze (2011–2015)

The Cruze is affordable, but reliability concerns hold it back.

Common problems:

  • Cooling system failures
  • Turbocharger issues
  • Electrical problems

Repairs can add up quickly if the vehicle hasn’t been well maintained.

Dodge Journey (2011–2019)

This SUV is often inexpensive, but there’s a reason.

Common problems:

  • Weak engine performance
  • Outdated technology
  • Reliability issues

It may seem like a good deal upfront, but long-term ownership can be frustrating.

BMW 5 Series (Older High-Mileage Models)

Luxury cars can be tempting at a lower price, but maintenance costs are significantly higher.

Common problems:

  • Expensive repairs
  • Electrical issues
  • High maintenance costs

A cheap luxury car can quickly become expensive.

How to Avoid Buying the Wrong Car

To avoid these issues:

  • Research the model before buying
  • Check for known problems
  • Get a pre-purchase inspection
  • Review maintenance history

Final Thoughts

The worst used cars aren’t always obvious. Many look like great deals at first but come with hidden costs.

Taking the time to research and inspect a vehicle before buying can save you from expensive mistakes.
