What year are mustangs most reliable?
The mid-2010s, especially 2015 through 2017, are commonly cited as the most reliable Mustang years based on surveys and owner reports. Individual cars vary, but well-maintained examples from this window tend to show fewer chronic issues than some earlier years.
Why reliability varies by year
Reliability depends on engineering changes, drivetrain options, and how well the car was maintained. The Mustang has undergone two major generational shifts since 2005, with the mid-2010s bringing a newer platform and updated electronics that sources frequently identify as more dependable when customers have kept up with service. While the 2015–2017 models are often highlighted, results can differ by engine choice (EcoBoost vs. V8) and by how the vehicle was cared for over time.
Best years for reliability
This list highlights model years that reliability surveys and owner feedback commonly regard as strong choices for durability, particularly when paired with complete maintenance histories.
- 2015 Mustang — debut of the current generation’s refinement, with updated electronics and a choice of efficient EcoBoost or robust V8 configurations.
- 2016 Mustang — continued improvements and solid reliability across engine options, making it a popular used buy.
- 2017 Mustang — final year before the 2018 refresh, often noted for dependable performance and a mature electronics package.
In addition, some buyers look at 2014–2015 transition models that benefited from early-generation improvements, but they should be mindful of electronics and software quirks that accompanied rapid platform changes. A strong maintenance history can mitigate many risk factors.
Reliability by generation: quick notes
Beyond year-to-year comparisons, the Mustang spans two generations. The Fifth Generation (2005–2014) introduced new engines and transmissions but ages with higher mileage; the Sixth Generation (2015–present) brought a more modern platform, independent rear suspension, and newer powertrains, with generally stronger reliability in well-maintained examples—especially from 2015–2017 and into later 2018–2020 models. Regardless of year, buyers should review recalls, service history, and perform a thorough pre-purchase inspection.
What to look for when buying a used Mustang
Use this checklist to assess reliability potential and avoid common pitfalls when evaluating a used Mustang. It focuses on history, maintenance, and wear that can signal future trouble.
- Obtain complete maintenance records, including routine services, tire replacements, brakes, and any major component work.
- Check recall status and ensure all campaigns have been addressed, especially for electronics and safety systems.
- Inspect for rust on the body and undercarriage, particularly in older units or vehicles from salted-road climates.
- Test drive to listen for unusual engine noises, misfires, or transmission glitches; verify smooth shifts in both manual and automatic transmissions.
- Assess suspension components, steering, and the condition of tires for wear consistent with miles and usage.
- Evaluate interior electronics (SYNC/MyFord Touch) for reliability; confirm software updates and dealer servicing have occurred where applicable.
- Be aware of EcoBoost-specific issues such as turbo-related oil consumption and carbon buildup, and verify oil usage history if applicable.
Conclusion: Reliability in Mustangs depends on the model year, how well it was maintained, and how it has been used. The mid-2010s generation remains the most frequently cited as reliable when paired with a solid maintenance record. A thorough pre-purchase inspection by a trusted mechanic and a complete service history are essential for any used sports car investment.
Summary: For buyers seeking the most reliable used Mustang, target model years 2015–2017, with EcoBoost or V8 variants and a clean maintenance history. Always verify recalls and electronics with recent service, and conduct a careful test drive and inspection to confirm long-term reliability.
