The picture
Across 6,558 MOT tests, the Fiesta Trend Turbo returns 83.2% first-time pass — above the UK fleet average. The single most-logged Major fail is shock absorber damaged to the extent. Headlamp aim out of spec and brake pads worn below 1.5 mm round out the top three. Average tested mileage sits at 18,817, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Year-band analysis
First-time MOT pass rate split by registration band. A 3.0-point gap between bands means the year you buy Ford Fiesta Trend Turbo has a real effect on what turns up at the garage.
Best band to buy
89.8%
2021+ registration
the 2021-on band climbs to 89.8% — a 3.0-point improvement. Tests in this band average 20,758 miles — roughly 5K miles fewer on the clock than the older band. Failures here are mostly wear items: less than 1.5 mm thick, tread depth below requirements of 1.6mm — the structural issues that drag down older examples don't appear in the top-10 for this band. Post-2020 examples are early in their MOT life and generally show the cleanest records.
Band to be cautious about
86.8%
2018–2020 registration
On the 2018–2020 band, the data shows a 86.8% pass rate against a fleet average of 89.8% on the newer band. The main culprits logged at test: has a serious fluid leak, less than 1.5 mm thick, and tread depth below requirements of 1.6mm. Average mileage on test for this band is 25,892 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (89.8% first-time pass). Worst band to avoid: 2018-2020 (86.8% pass). That's a 3.0-point spread across 8,651 older tests and 3,390 newer ones — year of build makes a material difference on this model.

What's good
The Ford Fiesta is the first car many people ever drive and, for many, it’s all the car they will ever need. Its versatility, low running costs and practicality are all at their best in this generation of Ford’s superlative hatchback.
Where it falls short
Several Fiesta models including Vignale now list at more than £20,000.
Report of a one year old Ford Fiesta Ecoboost MHEV where the 12v battery keeps running down so the air con will not work.
Heater failure on 2017 Ford Fiesta 1.0 EcoBoost The heater fan ceased to work on two occasions in any position except four, the highest. Each time the repair was done by fitting a new resistor. The latest repair failed again. Ford dealer now thinks that to effect a proper repair a new heater motor will have to be fitted. They say that five and a half hours labour will be required as access has to be carried out through the dashboard. The new motor will cost approximately £400 and the total bill will come to just over £1000. Unclear if the dealer or Ford will contribute towards the cost of the repair.
Problems reported with 2021 1.0 mHEV Fiesta. After three weeks of ownership there were problems with the passenger door touch sensitive unlocking. Owner took the car back to the dealer who said it was because the 12v battery was low (40 per cent). They suggested that because the owner only does around 100 miles a week and the hybrid system is only really charging the hybrid battery, so the standard one is likely to regularly run down.
Report of 2020 Ford Fiesta breaking down on the drive home from the dealership. Engine warning light appeared on the dashboard with the message "low oil pressure". Dealership recovered the car and stated it needed parts to be ordered from Germany and the owner would have the car back in a week. Owner is rejecting the car under the consumer rights act 2015.
Complaint about Sync3 not working in a 2018 Ford Fiesta 1.0 Ecoboost ST-Line automatic. The Sync 3 system includes the Sat Nav, yet, even though it has WiFi it doesn’t update. Owner has tried downloading satnav updates to a USB to update but it doesn’t work. Sat nav goes blank, all roads disappear and he can only see the red arrow. This happens just about every day. The car has been back to the dealers and they have applied all available updates but confirm it’s not fixed until Ford provides a permanent fix. Owner having to try to use Apple Carplay and Google Maps.
Report of audible warning and light coming on in brand new Ford Fiesta 1.0 Ecoboost, then going off before driver can work out what it is for. It will be the petrol particulate filter warning which then self-cleans so the warning goes off.
Report of battery regularly going flat in a 2017 Ford Fiesta.
Strange issue reported with June 2018 Ford Fiesta 1.1 Titanium, bought used at 5199 miles in May 2019. Yellow spanner came up on the display (indicating a malfunction) and the engine lost power for about 5-6seconds, then regained full power, carried on for about a quarter of a mile and lost power again.
Report of stop-start function of new shape 2017 Fiesta 1.0litre Auto only cutting in on a couple of ocassions since purchase used 12 months previously. Back to the dealer twice but each time they say cannot find anything wrong with diagnostics. Owner says battery cannot be being charged sufficiently or is faulty otherwise the function would work. Does reasonable mileages and have had the battery go flat when car was unused for 4 days.
Complaint of 2017/67 Ford Fiesta refusing to unlock with the fob or the spare. Called AA who told her how to open the car manually with the hidden key, but that it's a known Fiesta fault where the keys forget the car and require a "software update". Both keys started working again. Supplying dealer said all they could do was replace both batteries and refused to acknowledge the fact that both keys miraculously started working again. Ford UK has denied any knowledge of an issue or a software update.
Report of 2017 new model Fiesta bought new in November 2017 running down its battery after having been left unused for 2-3 weeks.
Report of failure of the manual transmission of a 2018 Ford Fiesta 1.1 Zetec bought at 9 months old. On attempting to drive it home the new owner found he could not change gear. The car was then recovered by the AA, returned to the showroom and owner demanded a return of the vehicle and an immediate refund, which he eventually got in full. The Ford dealer subsequently informed him that this was, apparently, an occasional problem on Fiestas.

Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Fiesta Trend Turbo and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
