The Ford Mustang GT has long been an icon of American muscle cars, celebrated for its performance, sleek design, and rich heritage. However, like any vehicle, the S550 Mustang GT series, which spans from 2015 to the present, is not without its issues. If you’re considering investing in a used S550 Mustang GT, it’s essential to be informed about the years and models that have garnered a reputation for problems. This article delves deep into the Mustang GT’s most problematic years and the issues that plague them.
Understanding the S550 Mustang GT
The S550 generation of the Mustang GT introduced a new level of sophistication while maintaining the raw power that enthusiasts crave. From its robust V8 engine to the advanced technology features, the S550 was a step forward. However, it also came with its share of hiccups. Buyers need to be aware of particular model years that had significant manufacturing defects or quality control issues that could lead to costly repairs down the line.
Key Issues Across S550 Mustang GT Years
When examining the S550 Mustang GT, it’s invaluable to consider the common problems that have been reported by owners and automotive experts alike. Some of the most prominent issues are:
- Transmission Problems: Early models, particularly the 2015 Mustang GT, faced criticism for their automatic transmission. Owners reported rough shifts and hesitation when accelerating. A recalibration of the shifting algorithms later addressed these issues, but it’s still a concern for used buyers.
- Cooling System Failures: Overheating issues, particularly on models equipped with the Performance Pack, have been a hot topic among enthusiasts. Insufficient coolant circulation, due to radiator size and design flaws, can lead to significant engine problems.
- Interior Quality Concerns: The 2015 model year also has been noted for its less-than-stellar interior quality. Reports of rattling noises and issues with the fit and finish of interior components surfaced, leading to dissatisfaction among owners.
- Driveline Vibrations: Particularly in the 2016 and 2017 models, some owners reported droning sounds and vibrations during high-speed drives. This phenomenon often pointed to driveshaft issues, necessitating time-consuming repairs.
- Electrical Glitches: Tech-infused Mustangs often fall prey to electrical problems. Owners of 2015 to 2018 models have mentioned malfunctions with the infotainment system, leading to erratic behavior with navigation and media functions.
Identifying ‘Bad Years’ to Avoid
While every car has its unique quirks, certain years in the S550 lineup stand out due to recurrent issues reported by the community. The following will detail the so-called ‘bad years’ for the Mustang GT that potential buyers should approach with caution:
- 2015: As the inaugural year of this generation, the 2015 Mustang GT attracted a lot of attention, but it also delivered mixed reviews regarding its reliability. The transmission problems mentioned earlier left many owners frustrated, and reliability concerns were prominent.
- 2016: While improvements were made, issues with the driveline vibrations persisted. Additionally, problems with the climate control system began to surface for certain owners, leading to inconsistent temperature regulation.
- 2017: This model year saw a few recalls and consistent complaints about electrical issues that could lead to all sorts of errant behaviors in vehicle electronics. This unpredictability served as a turn-off for many potential buyers.
- 2018: While later models addressed many concerns, the 2018 Mustang GT still bore the brunt of unresolved problems from prior years. Reports of ongoing transmission issues and electrical glitches continued to proliferate.
Comparing Later Models: Improvements and Revisions
Starting with the 2019 model year, Ford made significant strides in addressing the problems plaguing the earlier S550 models. Owners and reviewers alike have noted a marked improvement in build quality and reliability attributes. For instance, the introduction of more robust electrical systems and better interior materials has greatly enhanced owner satisfaction.
Furthermore, the 2019 and subsequent models have seen better calibration in transmission systems, minimizing earlier hiccups. Improvements made to the Mustang’s cooling systems have resolved many overheating concerns that plagued the earlier iterations.
Tips for Potential Buyers
For those considering the purchase of a used S550 Mustang GT, several precautions can safeguard your investment:
1. Research Thoroughly: Familiarize yourself with the common issues of each model year. Online forums, owner reviews, and automotive websites can provide insights into the specific problems associated with the exact model you’re considering.
2. Check for Recalls: Investigate whether any recalls have been issued for the Mustang GT in the model year you’re interested in. Ensure that any required repairs have been completed.
3. Get a Pre-Purchase Inspection: Always have a trusted mechanic conduct a comprehensive vehicle inspection before making any purchase. This can help identify hidden issues that may not be visible at first glance.
4. Consider Warranty Options: If purchasing a vehicle that’s still under warranty, ensure that options for extending coverage exist. This insurance can save considerable amounts in case repairs become necessary down the line.
Ultimately, while the Ford Mustang GT boasts impressive performance and iconic styling, understanding the potential pitfalls of specific model years is crucial in making an informed purchase. Awareness of the S550 Mustang GT’s prevalent issues allows buyers to avoid costly mistakes and enjoy the pure exhilaration that comes with owning a Mustang.
