Hyundai i30 Common Faults in the UK
PD, 2017+ — compact family hatch. Updated 6 October 2026.
This guide covers the PD, 2017+ only. Older i30 generations have different engines and faults — for one of those, see how to check any car for known faults.
The PD Hyundai i30 (2017+) is one of the most reliable compact hatches in the UK. Owners report oil-pressure and injector issues on the 1.4 T-GDI turbopetrol before the 2020 facelift; the diesel 1.6 CRDi is solid. DCT (dual-clutch) on 1.4 T-GDI judders in low-speed traffic. Best-buy: 2020+ 1.6 CRDi or 1.0 T-GDI. Worst: 2018–2019 1.4 T-GDI DCT.
84.8% of Hyundai i30s registered 2017–2019 pass the MOT on the day (cars fixed during the test included), level with all cars registered in those years (84.2%). These are the cars this guide covers that were 3 to 12 years old when DVSA tested them in 2025, counted from 1,984 DVSA tests; a pass with rectification at the station counts as a pass here, and as a failure in DVSA's own initial-test measure.
Counting every registration year DVSA holds for the Hyundai i30 (2008–2019), which includes generations this guide does not cover, 71.2% pass on the day (cars fixed during the test included), from 10,713 tests.
Source: DVSA MOT Anonymised Data 2025 (Open Government Licence v3.0), a sample of the 2025 file (about one test in ten, from nine months). Class 4 tests in Great Britain, test type NT (a normal annual test), retests excluded. A pass, or a pass with rectification at the station, counts as a pass here (passed on the day); DVSA's own initial-test measure counts a rectified pass as a failure and so reports a lower figure. Testing in Northern Ireland is run separately by the DVA under its own rules. Compared against cars of the same registration years, because pass rates otherwise mostly measure how old a model's surviving fleet is.
See it by registration year and by mileage ↓The asking-price figures above are the middle 80% and the median of what sellers were asking on Autoza on 29 October 2026 — not what buyers pay — for Hyundai i30 cars registered from 2017. They are worked out from the cars on sale when this page is generated, and none is shown when fewer than 10 cars qualify. The road tax line comes from GOV.UK's vehicle tax rate tables (2026/27 rates). The other quick-stats values are indicative editorial estimates aggregated from owner-forum sentiment, recall data and reliability surveys. We do not publish a UK price index, and no figure here should be quoted as one.
Best and worst years to buy
We name a year as a best or worst buy only where the DVSA MOT table further down does not rate it the other way.
2020 facelift brought the 48V mild-hybrid system on 1.0 T-GDI variants, a revised 1.4 T-GDI with improved oil management, and the Bluelink connected car system. Hyundai's 5-year unlimited-mileage warranty means most 2020–2022 cars still have significant factory coverage remaining for an UK buyer.
The DVSA table below has no row for 2020, 2021 and 2022, so there is no MOT comparison behind those years here. 2023 cars are too new for the DVSA table below, so there is no MOT record behind that year yet.
Early 1.4 T-GDI examples (2018–2019) are the ones owners most often report oil pressure warnings and injector issues on. How often it happens is not known. The 7-speed dry-clutch DCT on these variants also had calibration issues causing low-speed judder in urban traffic — particularly frustrating for city commuters.
Known faults — Hyundai i30 PD, 2017+
How to read this list. Every item here is owner-reported: patterns that come up repeatedly with workshops, owner forums and reliability surveys. Those are worth checking on a viewing, but we hold no count of how many cars have each one, other than any survey share a card itself quotes. Treat an owner-reported item as a question to ask, not a fault this car has.
1.4 T-GDI engine — oil pressure warning
- Symptoms
- Oil pressure warning light on startup; engine noise at idle; low oil level despite no visible leak
- Years affected
- 2018–2019 1.4 T-GDI (before ECU calibration update)
- Indicative repair (UK)
- ECU update free under warranty; if engine damage occurred: £2,500–£5,000
- What to check before buying
- Dipstick at viewing — check level and colour. Ask if oil pressure warning has ever been triggered. Service history should show oil changes at Hyundai UK's petrol interval of 1 year or 10,000 miles, whichever comes first. Avoid 1.4 T-GDI without confirmed ECU update.
7-speed dry-clutch DCT judder (1.4 T-GDI)
- Symptoms
- Shudder when pulling away from a standstill in traffic; hesitation at low speeds; occasional "clunk" engaging Drive from neutral
- Years affected
- 2017–2019 DCT variants
- Indicative repair (UK)
- DCT software update free at Hyundai dealer; fluid change £150–£220; mechatronic fault £800–£1,500
- What to check before buying
- Test drive in heavy stop-start urban conditions — not just an open road. DCT should engage cleanly. Any shudder requires DCT software check and fluid condition inspection.
1.6 CRDi diesel — DPF (short-trip urban)
- Symptoms
- "DPF regenerating" warning; limp mode; reduced power
- Years affected
- All 1.6 CRDi diesel variants — Usage-pattern-driven
- Indicative repair (UK)
- £350–£650 forced regen; £1,400–£2,200 DPF replacement
- What to check before buying
- Ask seller about typical journey length. CRDi used exclusively for sub-6 miles school runs is a red flag. Avoid without evidence of regular 30-minute motorway runs.
TPMS sensor faults
- Symptoms
- Tyre pressure warning despite correct inflation; sensor unresponsive after tyre change
- Years affected
- All PD i30
- Indicative repair (UK)
- £80–£130 per sensor
- What to check before buying
- Check TPMS warning light on dash during inspection.
BlueLink infotainment freezes (pre-2021)
- Symptoms
- Touchscreen unresponsive; Android Auto drops; reboot needed
- Years affected
- 2017–2020
- Indicative repair (UK)
- Free software update at Hyundai dealer
- What to check before buying
- Test infotainment for 15 minutes during drive.
Front lower control-arm bushings
- Symptoms
- Knocking over rough UK roads; mild handling vagueness
- Years affected
- All PD — 55,000+ miles
- Indicative repair (UK)
- £220–£380
- What to check before buying
- Speed bump test during drive.
Hyundai i30 MOT results by year and mileage
Measured from DVSA’s own MOT test records for tests carried out in 2025, not from owner reports.
By registration year
Against all cars registered in the same year, the MOT pass rate for the i30 was lower in 3 and level in 4 of the 7 registration years from 2013 to 2019 with enough tests to measure. The widest gap below is 2013 registrations: 65.5% against 71.9% for all cars registered that year.
Pass rate here: passed on the day, cars fixed during the test included. Rows: every Hyundai i30 DVSA tested in 2025, by registration year (2013–2019), all engines and fuels together. 2013–2016 registrations are older generations of the i30 than this guide covers, shown for comparison; the guide’s own cars start in 2017. A registration year cannot separate two generations exactly when one replaced the other part-way through a year.
| Registered | i30 | All cars that year | Difference |
|---|---|---|---|
| 2019438 tests | 87.0% | 86.9% | +0.1 level |
| 2018793 tests | 85.9% | 84.5% | +1.4 level |
| 2017753 tests | 82.3% | 82.2% | +0.1 level |
| 2016945 tests | 76.2% | 79.4% | −3.2 lower |
| 20151,442 tests | 75.5% | 76.7% | −1.2 level |
| 20141,054 tests | 69.5% | 74.3% | −4.8 lower |
| 20131,095 tests | 65.5% | 71.9% | −6.4 lower |
By mileage at the test
Against cars of the same age on the same mileage, the pass rate for the i30 was lower in every one of the 2 mileage bands with enough tests. How other models compare at the same mileage.
Show the table by mileage (2 bands)
| Mileage | i30 | Same age and mileage | Difference |
|---|---|---|---|
| 60k–80k2,540 tests | 72.4% | 75.1% | −2.7 lower |
| 80k–100k2,159 tests | 66.7% | 70.4% | −3.7 lower |
Only a major or dangerous defect fails an MOT. A minor defect is recorded on the certificate and the car still passes, and an advisory is not a failure at all.
We don’t give a recall count for the Hyundai i30: whether a recall applies depends on the individual car. Check the one you are looking at by entering its registration on GOV.UK’s vehicle recall checker, and see how to check a car for known faults for the other free checks.

Class 4 tests in Great Britain, test type NT (a normal annual test), retests excluded. A pass, or a pass with rectification at the station, counts as a pass here (passed on the day); DVSA's own initial-test measure counts a rectified pass as a failure and so reports a lower figure. Odometer readings below 100 or above 400,000 miles are discarded as misreadings, and cars under three years old are excluded because no MOT is yet due. Sampled from nine months of 2025 (January, February, April, May, July, August, September, October and November). Testing in Northern Ireland is run separately by the DVA under its own rules. Registration years shown are cars 3 to 12 years old when tested; the smallest rests on 438 tests. A gap is called level when it is under one percentage point or inside the 95% sampling margin for that number of tests.

Is the 1.4 T-GDI engine — oil pressure warning on the Hyundai i30 a serious problem?
Owner-reported, frequency unknown: 1.4 T-GDI engine — oil pressure warning comes up in owner forums and workshop reports for the Hyundai i30, but how often it happens is not known, so treat it as a question to ask rather than a fault every car has. Symptoms: Oil pressure warning light on startup; engine noise at idle; low oil level despite no visible leak. Years affected: 2018–2019 1.4 T-GDI (before ECU calibration update). Indicative repair cost in the UK: ECU update free under warranty; if engine damage occurred: £2,500–£5,000. What to check before buying: Dipstick at viewing — check level and colour. Ask if oil pressure warning has ever been triggered. Service history should show oil changes at Hyundai UK's petrol interval of 1 year or 10,000 miles, whichever comes first.
