A genuinely great-driving Mustang with two very different personalities under the hood — and one of them (2.3 EcoBoost with coolant intrusion risk) can grenade its engine.
Every documented failure, earliest first
Ordered by the mileage the problem typically appears. VERY HIGH
confidence means it's tied to a documented NHTSA recall, and 1 of these are rated Critical.
20k–60k mi● Plan$0–$4,500VERY HIGH
10R80 10-speed automatic harsh/delayed shifts, hesitation from a stop, occasional hard lockup
How to catch it: Get the latest TCM software flash at every dealer visit — Ford has issued multiple recalibrations (including TSB 24-2254 territory) that fix a lot of the jerkiness for free.
Source: documented (NHTSA recall)
30k–70k mi● Plan$150–$500MODERATE
Trunk-to-body wiring harness chafing/breaking (backup camera, tail lights, brake lights)
How to catch it: Inspect the trunk hinge wiring boot for cracking and add a wire loom or wrap before it frays and kills your lights/camera.

40k–90k mi● Watch$150–$600MODERATE
Coyote V8 exhaust manifold bolts/studs snapping causing ticking and exhaust leak

50k–100k mi● Watch$400–$1,800VERY HIGH
MT82 manual transmission notchy 2nd-3rd gear synchro wear and clutch hydraulic line failures
How to catch it: Use Ford-spec MERCON LV or upgraded fluid on any track-driven manual and replace the clutch slave cylinder proactively if you feel spongy pedal feel.

60k–130k mi● Critical$8,000–$12,000HIGH
2.3L EcoBoost coolant intrusion into cylinders via cracked cylinder head/head gasket, leading to catastrophic engine failure

Source: owner-reported (44 NHTSA complaints)
80k–120k mi● Watch$300–$900MODERATE
Rear subframe/IRS bushing wear causing clunks and rear-end vagueness
