Ford Mustang S650 — Problems & Common Faults
Weaknesses, engine ratings and buying advice
The S650 has been the current Mustang generation since 2024 — and it's the last one guaranteed to keep a naturally aspirated V8, something Ford leans into hard as pony-car rivals go turbo or disappear. It's a mechanically honest sports car wrapped in a genuinely modern, and sometimes overcomplicated, electronics layer.
Our database covers the Coyote-Gen3 5.0-liter V8 exclusively. Port-plus-direct injection keeps the intake valves clean, so the carbon-buildup problem of pure-DI engines doesn't apply. US-spec GT is rated at 480 hp and Dark Horse at 500 hp; the figures in our engine data (334 kW/454 PS GT, 333 kW/453 PS Dark Horse) reflect the emissions-detuned European versions — expect a real power gap comparing a European build sheet to a US one. Gearbox choices are a 6-speed Getrag manual, a 10-speed automatic, and on Dark Horse a tighter Tremec TR-3160 manual. Known engine-side items: VCT solenoids on the exhaust side of bank 2 (Ford TSB 18-2360), a high-pressure fuel pump that can fail around 50,000 miles, and spark plugs that run hot enough to warrant preemptive replacement for track use.
Recall activity has been unusually heavy for a new platform. Most recently, in September 2026 Ford recalled roughly 148,663 model-year 2024–2026 Mustangs (NHTSA campaign 26V547) built at Flat Rock between September 2022 and June 2026: engine-bay wiring harness ground terminals can fatigue and fracture, risking loss of engine power, headlights, or HVAC — Ford estimates only about 1% of the recalled fleet actually has the defect. Earlier campaigns cover a steering torque sensor fault that can make the wheel oscillate, a digital instrument cluster that can go dark mid-drive, a rear-view camera that freezes under SYNC4 (fixed via software update), a body control module that lets water in through the windshield seal and makes exterior lights flicker, ADAS features that can malfunction from a software bug, and — manual cars only — a clutch line that can sag onto hot components and ignite if a retaining nut isn't secured. Ford Performance separately recalled bolt-on Whipple supercharger kits over a calibration bug that disables safety functions. Day to day, the bigger irritant is SYNC4 freezing or restarting, plus touchscreen-only HVAC controls owners call a step back ergonomically. Stock GT brakes without the Performance Package also show cracking and warping under sustained track use.
Test-drive checklist: Idle tick is normal for a Coyote; unusual knock under load isn't. Run the manual through all gears checking for notchy shifts, or the 10-speed for hesitation. Test SYNC4 for freezing and check the rear camera. Inspect the undercarriage and exhaust for early corrosion, especially on cars that have seen winter road salt.
2026 market: New 2024 GT manual started at $44,090, GT Premium $48,610, Dark Horse $60,865, Dark Horse Premium $63,460 — all including destination. 2025 Dark Horse pricing moved up to $62,925–$66,920.
The S650 remains a mechanically honest sports car with genuinely strong resale prospects as naturally aspirated V8s disappear from the market — but buy with recalls completed and budget for track-oriented maintenance if you plan to use it hard.
Insider pick: Dark Horse with the Tremec manual — a tighter gearbox than the standard Getrag in the GT, stiffer chassis tuning, and the most honest path to the Coyote V8 experience.

Generations
Engine Overview
The Ford Mustang S650 is available with 3 engine variants — from 446 to 454 hp.
Gen 3 Coyote from 2018 — the key upgrade was dual fuel: direct injection plus port injection simultaneously. The port injectors keep the intake valves clean, eliminating the carbon buildup problem of DI-only engines. A 7,500 rpm redline. At idle the familiar Coyote tick, at part throttle a smooth V8 hum, at wide-open past 5,000 rpm the cross-plane character comes through — not as sharp as a flat-plane but fuller and deeper. Active exhaust valves let you choose between neighbor-friendly and antisocially loud. VCT solenoids on exhaust bank 2 are the known issue — Ford TSB 18-2360 covers it. High-pressure fuel pump can fail around 50k miles. Ignition coils are heat-sensitive, replace prophylactically if tracking the car. Tuning potential is enormous: a Whipple Gen 5 supercharger delivers near-stock reliability with a big power jump. Oil changes 5W-20 every 5,000 miles.
- !! High-Pressure Fuel Pump Failing from 80,000 km
The direct injection high-pressure fuel pump on the 5.0 Coyote Gen3 can fail, leading to starting difficulties or power loss. Known failure tendency especially after 80,000 km.
Symptoms: Difficult cold starting, power loss, rough idle, check engine light - !! Head Gasket Failed — Overheating Damage from 80,000 km
The Coyote 5.0 V8 from 2011 is known for head gasket failures, especially after overheating events. Engine overtemperature from cooling system problems leads to warping of the aluminium head.
Symptoms: White smoke from exhaust; oil level rising with coolant mixed in (mayonnaise effect at oil filler cap); coolant loss without visible external leak. - !! VCT Solenoid Bank 2 Exhaust (TSB 18-2360) from 40,000 km
Ford TSB 18-2360 for 2018/2019 Coyote Gen3: Bank 2 exhaust VCT control solenoid faulty. Causes power loss and idle problems. Solenoid replacement by the dealer.
Symptoms: Rough idle; engine stumbling; power loss; ticking at bank 2; fault code P0022.

Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Recall: steering wheel oscillates due to torque sensor fault A fault in the electric power steering's torque sensor can, together with a simultaneous steering angle sensor failure, cause the steering wheel to oscillate while turning. Symptoms: Steering wheel noticeably vibrates or oscillates while turning. | Low | |
| Recall: instrument cluster fails after startup or while driving The digital instrument cluster can fail after engine start or while driving, meaning speed and other information is no longer displayed. Symptoms: Digital cockpit stays black at startup or shuts off while driving, speedometer and warning lights invisible. | Low | |
| Recall: clutch line can melt – fire risk An unsecured nut can cause the clutch pedal to fail. If the clutch line sags as a result, it can melt against hot components, leak brake fluid, and ignite. Affects manual-transmission vehicles only. Symptoms: Clutch pedal suddenly goes soft or fails completely, engine can stall. | Low | |
| Recall: Engine bay wiring harness ground eyelets can crack (26V547) NHTSA recall 26V547 (September 2026): on roughly 148,663 Mustangs built 2024–2026, ground eyelet terminals in the engine compartment wiring harness can fatigue-crack. Ford estimates about 1% of vehicles are affected. Symptoms: Illuminated Check Engine Light, instrument cluster warning messages, or an audible chime; in the worst case, loss of motive power, headlights, windshield washer, A/C, or the engine cooling fan. | Low | |
| Recall: ADAS driver assistance systems malfunction Various assistance systems (parking aid, drowsiness/distraction warning, intelligent speed assist, lane departure warning, automatic emergency braking, traffic sign recognition) can malfunction due to a software error. Symptoms: Assistance systems fail to respond, respond incorrectly, or not at all. | Low | |
| Recall: water intrusion into body control module – lights flicker Leaks in the windshield sealant allow water to enter the body control module (BCM). This can cause side marker and tail lights to flicker or fail. Symptoms: Lighting flickers, individual lights (side markers, tail lights, license plate light) intermittently fail. | Low | |
| Recall: rearview camera image freezes (SYNC4) The rearview camera image can freeze, meaning objects behind the vehicle may no longer be displayed. Fixed via a SYNC4 software update. Symptoms: Rearview camera image stops updating or freezes while manoeuvring. | Low |
