2017 Ford Mustang EcoBoost — Should You Buy One?
Typical asking price: $16,000–$26,000. There are 2 high-severity known issues you need to know before handing over a check.
Kestrel Take
Fun car, direct injection problem, questionable previous owners. The 2.3L EcoBoost carbons up from day one, the MT82 manual is fragile when driven hard, and Mustang buyers don't exactly baby them.
Known Issues for the 2017 Ford Mustang EcoBoost
Ranked by wallet impact. These are documented, recurring problems — not freak accidents.
Direct injection means no fuel washing intake valves. Carbon deposits cause rough idle, misfires, power loss by 60-80k. Walnut blast fixes it but it returns.
Repair cost range: $300-$700
3rd gear synchro wears early, cold engagement is stiff, clutch wears fast with enthusiastic driving.

Independent rear suspension bushings wear from spirited driving, causing rear-end looseness.
