Summary

The 2015 Ford Mustang has a range of potential issues, with engine and transmission problems being the most concerning due to their potential severity and cost. The 2.3L EcoBoost can suffer from turbocharger failure and coolant intrusion, while the 5.0L Coyote is prone to knocking noises and oil consumption. The MT82 manual transmission can be difficult to shift, and the 6R80 automatic can exhibit rough shifting. Electrical glitches with the MyFord Touch/Sync system are also relatively common, although often less expensive to resolve. Potential buyers should carefully inspect any 2015 Mustang they are considering, paying close attention to engine and transmission performance, and be aware of the potential for costly repairs.
