The average price of a new vehicle in the United States now exceeds $50,000. That’s one reason many buyers turn to the used-car market hoping to save money.
But not every used vehicle is a smart financial decision. Some models come with reliability concerns that can lead to unexpected repair costs and long-term ownership headaches.
Based on reliability data trends reported by Consumer Reports, recall history tracked by federal safety regulators, and commonly reported service issues discussed by independent mechanics, here are five used vehicles buyers should research carefully before making a purchase decision.
1. 2021 Ford Bronco Sport (Especially 1.5L Models)
The Bronco name has strong off-road heritage, but the first model year of the redesigned Bronco Sport experienced several reported reliability concerns.
Some owners reported issues involving:
- fuel injector concerns in certain 1.5-liter engine vehicles
- oil leaks
- braking system warnings
- electrical system faults affecting drivability
Federal safety regulators issued recalls related to potential fuel injector cracking that could increase fire risk under certain conditions. As with many first-year redesigns, early production vehicles sometimes experienced more issues than later model years.
Buyers considering this vehicle may want to confirm recall completion and service history before purchasing.
2. 2020 Ford Explorer
The 2020 Ford Explorer marked a major redesign that introduced a new platform and updated drivetrain layout.
Consumer Reports has long advised buyers to approach first-year redesign vehicles carefully, since early production versions sometimes show higher-than-average reliability concerns.
Reported owner issues included:
- rearview camera display malfunctions
- transmission shift behavior concerns
- axle component wear
- drivetrain-related service bulletins
While many of these issues were addressed through recalls or software updates, shoppers should confirm repair records and inspection results before purchasing this model year.
3. 2022–2023 Ford F-150 Hybrid (PowerBoost)
The hybrid version of America’s best-selling pickup introduced advanced technology designed to improve fuel efficiency and performance. However, hybrid systems add mechanical complexity compared with conventional gasoline vehicles.
Consumer Reports reliability surveys have identified some concerns involving:
- hybrid system electronics
- transmission behavior
- climate-control system faults
- software-related glitches
Hybrid battery replacement costs can be significant if failures occur outside warranty coverage, which makes it especially important for used-vehicle buyers to verify warranty status before purchasing.
4. 2021–2023 Jeep Grand Cherokee (Especially Plug-In Hybrid Models)
Jeep’s plug-in hybrid Grand Cherokee introduced advanced electrification features, but some owners reported reliability concerns involving electrical systems and charging components.
Plug-in hybrid vehicles combine gasoline and electric drivetrains, which increases diagnostic complexity compared with traditional vehicles.
Reported concerns included:
- charging system faults
- infotainment system instability
- warning-light activation related to hybrid components
Because plug-in hybrid systems often require specialized service equipment, repairs may be more expensive than conventional vehicle maintenance once factory warranty coverage ends.
5. 2018–2019 Ford Expedition
The Ford Expedition is known for strong towing capability and interior space, but some vehicles from these model years were associated with service bulletins related to transmission behavior.
Mechanics have reported concerns involving:
- harsh or delayed shifting
- cam phaser noise in certain engines
- suspension wear
- brake-system service issues
Transmission repairs on large SUVs can be expensive, making pre-purchase inspections especially important for buyers considering these vehicles.
Bonus: Used Tesla Vehicles — What Buyers Should Know
Consumer Reports reliability surveys have shown mixed results for older Tesla vehicles compared with some traditional luxury brands.
Earlier Model S vehicles in particular were associated with reports involving:
- suspension component wear
- touchscreen failures in early infotainment systems
- door handle malfunctions
Battery replacement costs for any electric vehicle can be significant outside warranty coverage. However, many Tesla vehicles still retain strong resale demand and high owner satisfaction in other categories such as performance and charging access.
Buyers should review warranty coverage carefully when shopping for a used EV.
How to Protect Yourself When Buying a Used Car in 2026
Consumer Reports and automotive experts generally recommend several steps before purchasing any used vehicle:
1. Check recall status
Confirm that all safety recalls have been completed using the vehicle identification number (VIN).
2. Avoid first-year redesign models when possible
Newly redesigned vehicles sometimes show higher early reliability concerns.
3. Review maintenance records
Consistent service history is one of the strongest indicators of long-term reliability.
4. Get a professional inspection
A pre-purchase inspection from a qualified mechanic is one of the most effective ways to avoid unexpected repair costs.
5. Compare long-term reliability ratings
Brands such as Lexus, Toyota, and Mazda have historically performed well in long-term reliability surveys.
The Bottom Line
Buying used is still one of the smartest ways to reduce vehicle ownership costs in the United States. However, reliability differences between model years can be significant—even within the same brand.
Before committing to a purchase, reviewing recall history, maintenance records, and independent reliability data can help you avoid vehicles that may cost more to repair than they are worth.
A little research before you buy can save thousands later.
