3 known faults with sources

Applies if: Same R-family CRDi diesel (D4HA/D4HB) as the Sorento II, where the German guide documents the chain and fuel filter.

Timing chain, fuel filter and clutch on the Sorento II 2.2 CRDiValve timing

Engine / equipment: Kia Sorento II 2.2 CRDi
Period mentioned: 2009–2014
Symptoms: Chain noise at high mileage, hesitation or loss of power from a clogged fuel filter, turbo whistle and a worn clutch when towing; on automatics, harsh shifts.
Possible cause described: The guide recommends replacing the chain at around 100,000 km to stop it breaking. The fuel filter often clogs and the clutch wears out before 60,000 km when towing. On the automatic, changing and flushing the oil helps.
Check for the garage: Listen to the chain when cold, change the fuel filter on time and test the clutch under load; on automatics, check the gearbox oil.

Applies if: Only the 1.7 CRDi (U family); the 2.0 CRDi belongs to the R family.

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.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

Applies if: Weak points of this model from inspections, breakdown statistics and recalls; anything specific to one engine is stated in the sheet.

Steering joints, drive shafts, starter and recalls on the ix35Known weak points

Engine / equipment: Hyundai ix35 (LM), petrol and diesel
Period mentioned: 2010–2015
Symptoms: Poor roadworthiness-test results for steering joints, drive shafts, lights and brakes; a starter that fails more than normal on the petrols; on the 1.7 CRDi, isolated cases of a stretched chain; rust on the tailgate on some cars.
Possible cause described: The German guide rates the 1.7 CRDi as unproblematic; on the diesels typical wear (particulate filter, dual-mass flywheel, turbo, EGR, injectors) comes with high mileage or many short trips. Recalls: driver’s seat-belt pretensioner (built 10/2011–6/2012) and the brake booster on some 2011 1.7 diesels.
Check for the garage: Check outstanding recalls by VIN (manufacturer, KBA or ADAC website) and have a garage inspect the points listed before buying or before the roadworthiness test.
