The picture
Across 2,072 MOT tests, the I10 N Line T-Gdi returns 87.2% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is a defective wiper blade. Wipers that don't clear the screen and a tyre with the cords showing round out the top three. Average tested mileage sits at 18,079, 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 2.4-point gap between bands is modest — the year you buy Hyundai I10 N Line T Gdi makes a small but real difference to MOT outcomes.
Best band to buy
89.2%
2018–2020 registration
the 2018–2020 band climbs to 89.2% — a 2.4-point improvement. Failures here are mostly wear items: does not clear the windscreen effectively, has a tear, caused by separation or… — the structural issues that drag down older examples don't appear in the top-10 for this band.
Band to be cautious about
86.8%
2021+ registration
On the 2021-on band, the data shows a 86.8% pass rate against a fleet average of 89.2% on the newer band. The main culprits logged at test: blade defective, does not clear the windscreen effectively, and has ply or cords exposed. Average mileage on test for this band is 17,541 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2018-2020 (89.2% first-time pass). Worst band to avoid: 2021+ (86.8% pass). That's a 2.4-point spread across 1,775 older tests and 297 newer ones — year of build makes a material difference on this model.

What's good
A brilliant executed city car that offers superb value for money, the Hyundai i10 can easily mix it with the Toyota Aygo and Volkswagen Up.
Another rattle reported behind the dash of a 2019 Hyundai i10, probably for the same reason as the KIA Picanto (above).
Rattle in front passenger area of new KIA Picanto 1 spec, found to come from loose unused wiring connection block banging against a body part. Easily fixed by straightening and moving the wiring and block.
Report of 2014 Hyundai i10 1.2 shearing off its crankshaft pulley, throwing its alternator belt and losing most of its oil. Always dealer serviced. 75k miles and 2 months out of 5 year warranty. Dealer wants £1,000 to fix. Owener had car towed to his regular Hyundai dealer in Reading. They spoke to Hyundai who gave him 10%, and they added another 10% and replaced the pulley plus crankshaft oil seal, bolt and belt, so the bill was £383. Owner also spoke to the Hyundai dealer it got towed to in Slough who offered him the £90 inspection fee back. The bolt had sheared off the crankshaft sprocket that holds the pulley on and the belt fell off, similar to what used to happen to the previous generation i10.
Report of rusted rear brake discs on 2017 Hyundai i10.
Report of intermittent "disturbing noises" from engine of 2015 Hyundai i10 1.25 automatic when taking right hand bends. Owner left car with dealer for testing while on holiday and dealer found failed oil riser that meant the engine was not being lubricated correctly. New engine fitted under warranty.
Report of parking brake of October 2017 Hyundai i10 Premium SE failing after being parked on a slightly sloping drive. What happened was that the parking brake cable simply snapped under tension.
Report of leaking bulkhead seal of March 2018 Hyundai i10 Premium SE Auto. First noticed January 2019. Hyundai dealer took 20 days to repair it. Now leak has returned.

Report of 13,000 mile 2015 Hyundai i10 1.2 Premium automatic slipping out of 4th gear at 2,000rpm. Dealer atttempted to re-set the sensor but problem still occurs. Does not happen at 2,500rpm where it settles into 4th.
Report of clutch failure on 2014 Hyundai i10 at 13,000 miles.
Report of surface rust on rear brake discs of 2016 Hyundai i10 found by the dealer during its 2nd service at just 5,000 miles. Dealer offered to clean them up for £287, which implies re-surfacing the discs on a special machine.
Report of a 2 year old Hyundai i10 needing replacement rear pads at 6,628 miles at a cost of £276.10 (pads or discs and pads?) and also needing the front brakes stripping and cleaning.

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 an I10 N Line T Gdi 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.
