The 1.0 and 1.5 T-GDI petrols and the 1.6 CRDi diesel are the main engines. The dual-clutch gearbox (DCT) and the diesel's filter, EGR valve and injectors cause most reported faults.
Reliability: 3/5, because the DCT and the diesel emissions parts fail often enough to matter.
DIY: 2/5, because DCT, filter, EGR and recall work need a workshop. Battery and brake checks are simple.
Prefer: a manual petrol car with full service history and the recall work done.
Avoid: a DCT that judders when pulling away from cold, and a diesel with a filter warning.

1.4 MPI (G4LC) and 1.5 MPI (G4LG): no fault confirmed in the sources read.
1.0 T-GDI 3-cylinder (G3LC, G3LF, G3LE, G3LH): no fault confirmed in the sources read.
1.4 T-GDI 140 PS (G4LD, to 2020): no fault confirmed. Offered with the 7-speed DCT.
1.5 T-GDI 48V (G4LK, 2020 on): no fault confirmed, including the 48V system. The 48V battery sits under the boot floor and cuts boot space (Auto Zeitung).
2.0 T-GDI i30 N (G4KH): no fault confirmed in the sources read. The DCT pressure recall is in the Recalls table.
1.6 hybrid (G4FY, 2026): no source covers faults yet.
1.6 CRDi diesel (D4FB to 2018, D4FE 2017 on): filter, dual mass flywheel, EGR valve and injector faults below. Hyundai dropped this engine in 2022 (Auto Zeitung).
6-speed manual: no fault confirmed in the sources read. RAC found no manual gearbox faults in its owner survey.
6-speed iMT (automated, 48V cars): no fault confirmed. Auto Zeitung says the clutch "takes getting used to".
7-speed dry DCT: judder and clutch wear, see DCT judder and clutch wear.
6-speed DCT: no fault confirmed in the sources read.
8-speed wet DCT (i30 N): pressure recall, see Recalls. No other fault confirmed.

Issue	Affects	Typical km	Repair cost
DCT judder and clutch wear	7-speed dry DCT (1.4 T-GDI 140 PS named)	Not stated; clutch wears at mid mileage	No confirmed price
Diesel filter clogging	1.6 CRDi diesel (D4FB, D4FE)	Not stated; short trips	No confirmed price
Dual mass flywheel wear	1.6 CRDi diesel	Not stated	No confirmed price
EGR valve contamination	1.6 CRDi diesel	Not stated	No confirmed price
Injector wear	1.6 CRDi diesel	High mileage, no figure	No confirmed price
Brake discs and pads	All	Not stated; from the second German MOT (HU)	No confirmed price

On a DCT car, drive slowly in traffic from cold and pull away from a stop. Judder, jerking or a delay is a bad sign. Ask for the gearbox oil change record and any software update. A scanner is needed to read gearbox fault codes.
On a diesel, check for a DPF warning light and ask for the filter regeneration history. A car that fails to regenerate on a longer run needs a filter check. A scanner is needed to read the regeneration data.
On a diesel, press the clutch and listen at idle. Vibration or a rattle can mean a worn flywheel. Ask whether the flywheel or clutch has been replaced.
Look through the wheel spokes for grooves or a sharp lip on the brake discs. Read the last inspection report, because brakes often fail the TÜV inspection.
On a diesel, a hard cold start, rough idle or high fuel use points to injector or EGR wear. A scanner should show no misfire or EGR codes. Ask for proof of cleaning.
Enter the VIN on Hyundai's recall page and in the KBA or ADAC recall databases. Ask the seller for any open campaign.
