12 Most Unreliable 2010s Cars to Avoid Buying

Identifying the most unreliable 2010s cars is crucial for used car buyers seeking to avoid powertrain failures and high total cost of ownership. While the 2010-2019 era produced many icons, models like the Ford Focus and certain Nissan SUVs are now major red flags due to known mechanical defects. The most unreliable cars from the 2010s include the Ford Focus and Fiesta due to PowerShift transmission failures, and Nissan models like the Juke equipped with problematic CVTs. Other high-risk choices for used car buyers include the 2011 Jeep Compass, 2013 Dodge Dart, and Land Rover Discovery models, which often suffer from expensive air suspension and engine issues.

The Transmission Traps: Ford Focus and Fiesta (2012-2018)

When you look at the landscape of least reliable used car models from the last decade, the Ford Focus and Fiesta sit at the very top of the "do not buy" list. The culprit is the DPS6 PowerShift transmission, a dry dual-clutch transmission that was marketed as having the fuel efficiency of a manual with the ease of an automatic. In reality, it became a mechanical nightmare.

The engineering flaw was rooted in the clutch material and the control module, which often suffered from fluid leaks that caused the clutches to slip and shudder violently. This wasn't just a minor annoyance; it was a safety hazard that led to the $77.4M Vargas v. Ford settlement. For many owners, the car becomes a financial total loss because the cost of replacing the transmission unit multiple times often exceeds the current market value of the vehicle.

If you encounter one of these on a used car lot, walk away. Even if the current owner claims the transmission was recently serviced, the design itself is fundamentally flawed. These 2010-2019 used car models with transmission problems remain the biggest gamble in the budget used car market today.

Safe Alternative: If you need a compact Ford, look for a manual transmission version of the Focus or Fiesta, which avoids the PowerShift issues entirely, or opt for a 2012-2017 Toyota Corolla.

Nissan's CVT Crisis: Rogue, Sentra, and Altima (2012-2017)

Nissan's reliance on JATCO-sourced continuously variable transmission units during the mid-2010s created a generation of unreliable 2010s cars that are now flooding the used market with hidden defects. These transmissions are notorious for overheating, which triggers a limp mode that limits engine RPM to prevent total meltdown.

The high maintenance used cars in Nissan's lineup, particularly the Rogue and Altima, often suffer from cooling system leaks that allow coolant to mix with transmission fluid. Once this "strawberry milkshake" occurs, the transmission is effectively toast. For unreliable 2010s cars to avoid for used car buyers, any Nissan with high mileage and a CVT should be approached with extreme caution. Out-of-warranty repairs for these units are notoriously expensive because they are often considered non-serviceable, requiring a total replacement rather than a simple fix.

Luxury Money Pits: Land Rover Discovery & BMW 5-Series (F10)

The allure of a cheap European luxury car is a siren song that has destroyed many bank accounts. The Land Rover Discovery is a prime example of a vehicle where vehicle depreciation happens almost as fast as its mechanical components fail. A 10-year maintenance cost study by Consumer Reports found that Land Rover owners spent an average of $19,250 on repairs and servicing, which was more than triple the $4,900 average for Toyota owners.

Common issues include air suspension failure, where the car sags to the ground and becomes undrivable, and catastrophic engine leaks. Similarly, the F10 generation BMW 5-Series (2011-2016) is one of the worst 2010s luxury cars for long term ownership if equipped with the N20 four-cylinder engine. This engine is famous for timing chain tensioners that fail prematurely; if the chain skips, the engine is instantly destroyed.

These are the most expensive 2010s cars to repair on the used market because parts are proprietary and labor hours for even "simple" fixes are double what you would pay for a domestic or Japanese brand.

The Engine Failure List: Dodge Dart and Chrysler 200

The early 2010s were a rough period for Chrysler's small and mid-sized sedans. The Dodge Dart and Chrysler 200 were intended to revitalize the brand, but they ended up on the used cars to avoid 2010-2019 lists due to the 2.4L Tigershark engine. These engines are known for extreme oil consumption, sometimes burning a quart every 1,000 miles without any visible leaks or smoke.

In the 2014 J.D. Power Vehicle Dependability Study, engine and transmission issues in 2011 model-year vehicles contributed to a 6 percent increase in reported problems, the first such decline in vehicle reliability since 1998. The Dart and 200 also suffered from a litany of infotainment glitches and electrical gremlins that often required multiple Technical Service Bulletins to address.

Methodology: How We Ranked These 2010s Lemons

To determine which vehicles made this list of unreliable 2010s cars, I analyzed several data streams. This includes long-term total cost of ownership data, consumer complaint volumes from the NHTSA, and historical reliability rankings from J.D. Power and Consumer Reports.

I specifically looked for "catastrophic" versus "annoying" failures. A broken radio is annoying; a snapped timing chain or a failed dual-clutch transmission is a financial disaster. Any car that appears on this list has a statistically higher probability of a powertrain failure that could cost more than 50% of the vehicle’s current value. Always perform a pre-purchase inspection before signing any paperwork on a car from this decade.

Better Alternatives: Reliable Used Cars from 2010-2019

If you want to stay in the 2010-2019 year range but avoid a headache, there are several reliable alternatives to the least reliable 2010s cars. The goal is to find vehicles with high component longevity and simple mechanical layouts.

• Toyota Camry (2012–2017): Often cited as the gold standard for reliability. The 2.5L four-cylinder and 6-speed automatic are nearly bulletproof.
• Honda Civic (2012–2015): While the 2012 model was criticized for its interior, the mechanicals are solid. The 9th generation is much more reliable than the 10th generation (2016+) with its early turbo issues.
• Mazda 3 (2014–2018): Using the SkyActiv-G engines and traditional 6-speed automatics, these cars offer a great balance of driving fun and long-term durability.
