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
  • Check for replacement-coupling history

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
