- 2006 Ford Mustang
- 2010 Ford Mustang
- 2011 Ford Mustang
- 2012 Ford Mustang
- 2015 Ford Mustang
- 2016 Ford Mustang

2006 Ford Mustang
The fifth-generation Mustang can last many years with proper care and maintenance, though certain model years may prove more troublesome than others. Buyers should be wary that certain model years might present additional issues than others.
Troublesome Mustangs tend to have lower FIXD reliability scores and higher Owner Reliability Scores compared to other models, which means more expensive repairs or issues may arise than usual.
The 2006 Ford Mustang stands out among this generation by having the most issues. Many of these involve its body and paint, including bubbling paint.
Some owners have reported finding two or three-inch-deep puddles of liquid within their vehicles. Interior leaks and rust can also cause problems; often, these issues can be corrected with simple solutions like tightening or replacing the gas cap.
2010 Ford Mustang
Although this generation won acclaim for its sleek design and powerful engines, transmission issues were encountered, as well as corrosion in hood-area corrosion areas and peeling paint on its bodies.
While these issues don’t compare to those found with previous generations of Ford Mustangs, they should still be considered when purchasing used. While these Mustangs are known for their performance and reliability, it is still wise to be mindful of any issues before buying one.
2010 brought two major years to avoid: the 4.6L V8 model and the 3.7L Cyclone engine. One was susceptible to oil leaks, while the other presented issues with its transmission and engine. While these issues are less serious than some, they can nonetheless be very irritating.
2011 Ford Mustang

Ford Mustang’s sixth generation model may have moved away from its pony car roots. Yet, it remains an exciting sports car with a modern engine and emissions technology – the most advanced Mustang ever produced!
Even so, the 2011 Mustang isn’t without its flaws: owners frequently experience peeling paint and rust around the hood as well as shaking and stalling due to an obstinate crankcase ventilation valve or PCV that needs replacement.
Still, 35% of Mustang owners who responded to our survey rely on their car for “lots of driving,” including traveling and commuting. Its positives outweigh its drawbacks – NHTSA crash test ratings remain strong while Owner Reliability scores remain excellent.
2012 Ford Mustang
Model year 2012 is also added to our today’s list of Ford Mustang years to avoid. The fifth-generation Mustang is beloved among car enthusiasts for its distinct looks and power, yet not without issues; specifically, the S197 chassis was beset with corrosion under its hood, broken backup cameras, water leaking into its air conditioning system, and broken gauges.
The 2012 Mustang was still an enjoyable car to own despite its many shortcomings. It received high NHTSA crash test ratings and outstanding fuel economy ratings, plus owners reported lower-than-expected annual maintenance costs (around $450 on average).
Some owners also complained of window breakages as well as DTC error codes like P0171 and P0174 being present – issues not worth overlooking when investing long-term in one of these cars.
2015 Ford Mustang

The sixth-generation Mustang offers performance, modern conveniences and history all rolled into one great package. Equipped with powerful EcoBoost engines and V8-powered GT models, as well as MagneRide suspension for agile handling and comfortable and spacious interiors well suited for daily driving, buyers are sure to find their dream vehicle in its sixth incarnation of the Mustang.
Ford Mustang is one of the most reliable sports cars on the market. It has proven itself in crash tests and earned excellent owner reliability ratings; however, owners should remain alert for issues like bubbled paint or rattles caused by vibratory transmission systems that might damage their vehicle.
The 2007 Mustang has earned itself a low-Reliability score due to several issues, such as issues with airbags and multiple recalls. Some can be addressed through simple repairs, while others could require costly replacement parts.
2016 Ford Mustang
Ford Mustang is an iconic sports car known for its breathtaking performance. However, purchasing a used Mustang can come with some challenges; when searching for your ideal model year and generation, consideration must be given, as buying any incorrect models could result in costly repairs down the road and costly maintenance bills.
There are various strategies you can employ to ensure you purchase a reliable Mustang model year.
Always purchase and conduct a thorough vehicle history report prior to making any decisions about purchasing one, have the engine and transmission checked by an independent mechanic, as well as avoid purchasing models equipped with Getrag MT82 manual transmission as these models have been known to experience ticks, rattles and noises that lead to frequent breakdowns.
2018 Ford Mustang
The Ford Mustang has long been one of the most iconic sports cars. Notable for its handling and performance capabilities as well as a comfortable interior featuring plenty of passenger space and cargo room, its ride quality is enhanced thanks to independent rear suspension with a MagneRide dampening system.
The Ford Mustang boasts a powerful EcoBoost engine, agile handling with its optional MagneRide suspension system and retro-inspired styling. Furthermore, modern conveniences such as Co-Pilot 360 safety software, Sync 3 infotainment system, and FordPass connect are included as standard.
There are certain years to be wary of when purchasing the sixth-generation Mustang, including 2015. These vehicles have received low FIXD Reliability Scores and numerous owner complaints regarding electrical systems, peeling paint and shaken engines – as well as multiple recalls that should serve as warning signals.
Which Ford Mustang Year To Buy Used?
The Ford Mustang is an indispensable road warrior. From maneuvering through congested streets to leaving competitors behind, this coupe elevates every journey.
Used Mustangs can bring years of driving pleasure for far less than the cost of purchasing new ones. But it’s essential to research which model years have minimal issues before making your purchase decision.
2005 To 2014
The Mustang is one of the world’s best-known cars, beloved and revered for decades. Iconic and intimidating in appearance while remaining relatively affordable relative to its competition, it offers first-time car buyers an exciting muscle car experience without breaking the bank.
Unfortunately, however, not every Mustang model is equally reliable as some owners can experience issues related to poor reliability issues – frustrating those who own one!
If you’re shopping for a used Mustang, later production years tend to offer more reliable vehicles with all of their kinks ironed out by then.
2020-2023 Mustangs make great choices for enthusiasts who desire modern models with upgraded performance features and upgrades; however, be wary of transmission issues or any repairs that may arise later down the line.
The 2011 Mustang GT is an excellent option for drivers seeking a reliable model with plenty of power and value. Boasting the Coyote V8 engine, sturdy construction, and classic Mustang styling with more modern touches – plus special attention should be paid to tires, brakes and clutches during testing! Just make sure all components work as they should before taking it out for its first test drive.
2015 To 2020
If you’re shopping for a Ford Mustang, it is essential that you carefully consider which model year would best meet your needs. By understanding which years make good investments and which should be avoided, you’ll be able to select an automobile tailored perfectly to you.
In 2015, Ford introduced its sixth-generation Mustang. This car offers buyers looking for an economical and roadworthy coupe a reliable option with superior handling and performance capabilities as well as cutting-edge technology features.
When searching for the ideal Mustang year to buy used, keep in mind that later model years generally offer better value because their flaws have already been resolved by that time.
As you search for your ideal Mustang, don’t forget to inspect its history report and test-drive it thoroughly. Check for issues such as bubbling paint or shaking before having it professionally inspected by an accredited mechanic.
2021 To 2025
Ford’s 2024 Mustang is an eye-catching coupe and convertible vehicle packed with horsepower. Equipped with a powerful 480hp V8 engine and cutting-edge tech features, its performance rivals cars with far greater output – such as the Toyota GR Supra, which boasts 382hp!
Although the latest Mustang has only recently hit the market, it already enjoys an excellent reputation for reliability. Consumer Reports awarded it with a perfect Reliability Verdict score and owner satisfaction was higher than other sports cars in its class. Furthermore, its spacious front trunk can fit a suitcase.
Your best bet for finding an economical 2020-2023 Mustang is to shop around dealer lots as new-car leftovers and demo units.
However, privately sold pre-owned Mustangs often represent better value. Be sure to inspect any pre-owned model carefully for damage or repairs that its seller never disclosed before making your final decision.
Before purchasing an electric vehicle such as the Ford Mach-E, be sure to have its main EV battery assessed by a professional mechanic. You should determine if the battery has been upgraded recently or has started losing charge, regardless of age.
For added peace of mind when purchasing pre-owned models, be sure to purchase at least three years or 36,000 miles of bumper-to-bumper coverage and five years or 60,000 miles of powertrain coverage as part of any pre-owned purchase agreement.
