6 Most Common Ford Mustang Problems

These are the faults most frequently seen on the Ford Mustang by UK garages — ranked by how commonly they occur and how much they cost to fix.

1
2.3 EcoBoost Coolant Issues
High Priority
The Mustang's 2.3 EcoBoost engine shares similar coolant system weaknesses to other EcoBoost units in Ford's range. Monitor coolant level and temperature carefully.
💷 Typical repair cost: £400–£900
2
Active Exhaust Valve Failure (V8)
Watch
The V8 Mustang's active exhaust valves can stick or fail. The exhaust note becomes consistently loud or the valves stop responding to the switch.
💷 Typical repair cost: £200–£600
3
IRS Rear Bushing Wear
Watch
The independent rear suspension introduced on the S550 Mustang means bush wear on the rear subframe. Clunking and vague handling are symptoms.
💷 Typical repair cost: £200–£500
4
Recaro Seat Track Issues
Watch
Some Mustang Recaro seat variants develop stiff or seized adjustment tracks — making seat positioning difficult.
💷 Typical repair cost: £100–£300
5
MyFord Touch / SYNC Faults
Low Priority
Older Mustangs running MyFord Touch infotainment can develop screen freezes and connectivity issues. Software updates usually help.
💷 Typical repair cost: £0–£200
6
Condensation in Tail Lights
Low Priority
A known cosmetic issue — condensation can build up inside the rear light clusters, particularly after wet weather.
💷 Typical repair cost: £50–£200

Ford Mustang — MOT Tips

Ensure all lights are functioning — the Mustang's LED lighting can fail individually and each failure is an MOT point. Check tyre wear carefully as the V8's torque can cause uneven rear wear.

Engine management light on before your MOT? It's an automatic fail. Run a MotorLoom diagnostic for £1.99 to get the likely cause and repair cost before booking the test.

Ford Mustang Tyres

Most Ford Mustang models run 235/55 R19 (EcoBoost) or 255/40 R19 (V8) tyres depending on trim level and year. Always check the tyre placard inside the driver's door for the correct size for your specific vehicle.
