3 known faults with sources

Applies if: Same type of direct-injection turbo engine (T-GDi).

Carbon on the injectors and intake of the T-GDi petrol enginesInjection / turbo

Engine / equipment: Hyundai and Kia 1.0 and 1.6 T-GDi direct-injection turbo petrol engines
Period mentioned: 2015 onwards
Symptoms: Loss of power, higher consumption, hesitation or rough idle, usually at high mileage.
Possible cause described: With direct injection, petrol does not wash the intake valves and carbon builds up on the injectors and intake. German guides mention it for the i20 III, Tucson IV and Picanto III (dirty injectors).
Check for the garage: Read misfire and fuel-trim codes; inspect the injectors and valves with a borescope; clean the intake if there are deposits.

Applies if: Second-generation i30 (August 2013 campaign). Confirm by VIN.

Handbrake that seizes because of a rusted guide pulley (Hyundai i30 II, 2013 campaign)Brakes

Engine / equipment: Second-generation Hyundai i30 (GD)
Period mentioned: 2012–2013
Symptoms: The handbrake is stiff, does not hold well or does not fully release.
Possible cause described: According to AUTO BILD, in August 2013 Hyundai recalled the i30 GD because the handbrake cable guide pulley could seize with rust. At the roadworthiness test the i30 GD also often fails on lighting and on the service brake and handbrake.
Check for the garage: Check by VIN with Hyundai whether the 2013 campaign has been done. Have the garage check the handbrake pulley and cable and how well it holds before the roadworthiness test.
Cost cited in the source: Free under the recall.A rough figure from the original database, not an up-to-date quote.

Applies if: Only with the 7-speed dual-clutch automatic (7DCT). Confirm the gearbox type.

Judder on the 7-speed dual-clutch gearbox (7DCT)Automatic gearbox

Engine / equipment: 7-speed dry dual-clutch automatic (7DCT)
Period mentioned: Approx. 2015–2021
Symptoms: Abnormal vibration or shudder when pulling away and at low speed, especially in traffic.
Possible cause described: Dual-clutch behaviour at low speed; Hyundai and Kia issued technical bulletins with new gearbox software (anti-judder logic) and, if that is not enough, a clutch replacement.
Check for the garage: At the dealer: run the judder test with the diagnostic tool, install the latest gearbox software and replace the dual clutch only if the judder remains.
