3 known faults with sources

Applies if: Diesel CRDi of the U family; the specific points were documented on other models with the same type of engine.

Weak points of the small CRDi diesels (U family) from Hyundai and KiaInjection / turbo

Engine / equipment: 1.1, 1.4, 1.5, 1.6 and 1.7 CRDi diesels (U family): Rio, Venga, Soul, Stonic, Cee'd, Carens, Optima, i20, ix20, i30, i40, ix35, Tucson, Accent, Matrix
Period mentioned: Approx. 2005 onwards
Symptoms: At high mileage or with short trips: carbon in injectors and EGR, a clogged particulate filter, dual-mass flywheel and turbo; isolated cases of a stretched chain (1.7) and cracked heads (early 1.6); a clutch that wears early; on some cars, a cracked silencer (1.1) or the brake-servo vacuum pump (1.7 campaign).
Possible cause described: German guides rate these engines as robust if maintained: the faults are the typical wear of a modern diesel. Specific points: a stretched chain on some 1.7s (ix35), cracked heads cited by the TÜV on the i30 I, the 1.1 silencer (Rio III), diesel clutches at 60,000–100,000 km (Cee'd I) and a recall of the 1.7 CRDi vacuum pump (5/10/2010–30/4/2011).
Check for the garage: Drive long trips to regenerate the filter; listen to the chain when cold; test injectors and EGR; check the vacuum-pump campaign by VIN on the 1.7.

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.
