Known faults on the 2020 Ford Fiesta
Reported by owners, mechanics and buying guides for this model and age. Check which engine the car has, as some apply to one engine only.
- 1.0 petrol (EcoBoost and non-turbo)
Timing belt that runs in oil (1.0 EcoBoost)
Ford’s 1.0 three-cylinder petrol uses a timing belt that runs in the engine oil on most cars. If oil changes are late or the wrong oil is used, the belt breaks down and sheds rubber that blocks the oil supply, which can wreck the engine. Some later cars have a timing chain instead: a Ford dealer can tell you from the VIN. Ford’s change interval is 10 years or 150,000 miles, and the belt isn’t covered by warranty.
At the viewing: Ask for a full service history with the right oil, and when the belt was changed. An oil-pressure warning light, a rattle or a rough idle are warning signs.

- Automatic versions only
PowerShift automatic gearbox
Automatic Fiestas with the PowerShift gearbox can give jerky changes, hesitate, or in bad cases lose drive. Repairs can be expensive.
At the viewing: If it’s an automatic, pull away gently from a standstill several times and drive in slow traffic. Any judder, clunk or hesitation is a warning sign.
Questions to ask the seller before buying a 2020 Ford Fiesta
Ask before you travel to see it. A seller who knows the car will have answers, and receipts.
- Has the timing belt been changed, and is there a full service history with the right oil?
- Any recent work on the shock absorbers? (Flagged at MOT 3.2× as often on the 2020 Ford Fiesta as on other cars the same age.)
- Any recent work on the headlight aim? (Flagged at MOT 2.8× as often on the 2020 Ford Fiesta as on other cars the same age.)
- Can I see the service history and receipts for any big jobs?
