Unconfirmed issues

Reported

Owner folklore from forums and the motoring press. Most of it never shows up in an MOT, which is why this section exists at all.

PowerShift automatic gearbox judder and failure

Confirmed pattern

The dry dual-clutch PowerShift automatic (fitted to some Mk7/Mk7.5 Fiestas) can judder, hesitate or bang into gear as the clutch packs wear early, because a dry clutch has none of the cooling a wet clutch gets. It's serious enough that Ford agreed cash payments, reimbursements and buybacks for affected Fiesta and Focus owners in 2017 after complaints piled up. A full clutch pack and mechatronic repair runs well into four figures if it's left too long.

1.0 EcoBoost wet belt failure

Confirmed pattern

The 1.0-litre EcoBoost drives its oil pump off a belt that runs in the oil rather than a chain or dry belt. If the tensioner lets go, belt material sheds into the sump, blocks the oil pickup and starves the engine, sometimes causing total failure with no warning beyond a knock or a sudden loss of oil pressure. Ford's own service interval is 150,000 miles or 10 years, but plenty of failures have turned up nearer 50-60k, which pushed regulators to investigate and Ford to issue a recall covering some affected cars. A full engine rebuild or replacement is £3,000-5,000+; a precautionary belt change is a few hundred pounds and cheap insurance.

Rear suspension knocks and creaks

Partly in the MOT data

Owners regularly report a clonk or knock from the rear over speed bumps and low-speed lumps, blamed variously on torsion beam bushes, loose top mount bolts, or worn rear damper bushes. The measured MOT data for this segment backs up suspension as the standout fault area for superminis generally, so the folklore and the numbers point the same way here. What the forums can't agree on is the exact cause, some fixes turn out to be as simple as retorquing top mount bolts rather than replacing anything.

Clutch judder from the dual-mass flywheel

Disputed

On manual 1.25/1.4 Duratec petrol and TDCi diesel cars, owners report a shudder through the clutch pedal, worse from cold, which is commonly pinned on the dual-mass flywheel wearing or a failing clutch. It's not universal and some owners drive 100k+ with no issue, so it's more a lottery than a design fault. A clutch and flywheel replaced together typically runs £500-900.

Blower motor stuck on full speed

Emerging

A common electrical niggle on 2011-2018 cars: the heater fan only works flat out on its top setting, or cuts out completely, because water gets past the cowl panel, soaks the cabin filter and drips onto the blower resistor until it fails or blows a fuse. It's a cheap fix, the resistor sits behind the glovebox and takes under half an hour to swap, but it's a nuisance and worth checking on a test drive.

Diesel DPF and EGR clogging on short runs

Diesel only

1.4 and 1.5 TDCi diesels that spend their life on short trips struggle to get hot enough to burn off the diesel particulate filter, leading to warning lights, poor economy and occasional forced regens that hammer fuel consumption. The EGR valve can gunge up in the same conditions. Not really a design fault so much as the wrong car for the job; a DPF replacement or professional clean is £500-1,500 if it's left too long. Doesn't apply to petrol Fiestas.

Viewing one? Ask this

Built from the two sections above.

Book a viewing with a cold engine and pull away gently on a manual. Judder or a shudder through the clutch pedal points to dual-mass flywheel or clutch wear.
On an automatic, do several stop-start gear changes including reverse. Hesitation, banging into gear, or a juddering take-off is the PowerShift clutch pack wearing.
Ask for the service history and check for a cambelt/wet belt entry on 1.0 EcoBoost cars. No belt change by 150,000 miles, or a car nearer 60k with no record at all, is a real risk, not just paperwork.
Drive over a speed bump or rough patch at low speed with the radio off. A clonk or knock from the rear is the common suspension complaint for this model.
Run the heater fan through all its speed settings. If it only blows on the top setting, the blower resistor has likely failed.
On a diesel, check for a DPF warning light and ask how the car is normally used. A history of short urban trips only raises the chance of a clogged DPF or gummed-up EGR.
Read the full MOT history online, not just pass/fail. Repeated advisories for the same suspension component across several tests means it's being ignored, not fixed.
