Hyundai i20 (GB) Common Problems & Reliability

The GB i20 feels far more mature than the PB and is one of the better-value used superminis in the UK. It is usually dependable, but buyers still need to screen for steering-column noises, low-use diesel issues and front-end wear on hard-driven cars.

Most Common Hyundai i20 (GB) Faults & Repair Costs

Low Risk

EPS flex-coupling and steering-column knock

Est. Cost£100–£240

The electric power-steering motor coupling can wear and produce a distinct knock or graunch through the wheel, especially at low speed or when shuffling into parking spaces.

Warning Signs:

Knock through steering wheel, Noise when rocking wheel left and right, Feels worse when parking

What to Check Before Buying:
  • Turn the wheel gently off-centre while stationary
  • Drive slowly over rough surfaces

Moderate Risk

DPF and EGR clogging on 1.1 CRDi

Est. Cost£180–£900

The smaller CRDi is economical but dislikes repeated cold starts and school-run use. When regeneration is interrupted too often, DPF and EGR faults quickly follow.

Warning Signs:

DPF or engine warning light, Cooling fan running after shutdown, Flat performance, Frequent regeneration attempts

What to Check Before Buying:
  • Ask about typical trip length
  • Look for recent EGR, DPF or injector work
  • Check exhaust smoke and idle quality from cold

Low Risk

Air-conditioning condenser leaks

Est. Cost£220–£420

Stone damage and corrosion at the front condenser are common enough to turn a seemingly tidy i20 into an air-con repair bill, particularly on motorway-used cars.

Warning Signs:

Weak air conditioning, Compressor cycles but cabin stays warm, Recent regas that did not last

What to Check Before Buying:
  • AC output on a warm day
  • Condenser fins for stone damage
  • Pipe unions for oily residue

Essential Pre-Purchase Step

Buying a used Hyundai i20 (GB)? Always check for hidden finance and write-off history.

Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.

Inspection Checklist for Hyundai i20 (GB) Buyers

✓A tidy GB should feel refined rather than flimsy, so knocks from the steering or front suspension are worth pricing properly
✓The 1.2 petrol is the safest ownership bet; diesel cars only make sense if they have covered enough A-road or motorway miles
✓Check air conditioning and radiator area carefully because the nose is exposed to stone damage
✓Use the MOT record to spot repeat advisories for front bushes, brake imbalance or weak headlamp output
