2 known faults with sources

Applies if: Only the 1.6 GDI (Gamma); the campaigns cited are from the US: confirm by VIN.

Connecting rods and pistons on the 1.6 GDI (Gamma)Engine

Engine / equipment: 1.6 GDI Gamma: Kia Soul II and Carens IV, Hyundai Veloster, i40 and ix35
Period mentioned: 2012–2016
Symptoms: Engine knock, oil-pressure warning and loss of power; with an overheated catalytic converter, abnormal combustion that damages the pistons.
Possible cause described: Two defects documented in the US: on the 2012–2016 Kia Soul, high exhaust temperatures could damage the catalytic converter and, with it, pistons and connecting rods (recall 19V-120, new protection software); on the 2015–2016 Veloster, the connecting-rod bearings wore early (recall 20V-746, KSDS software).
Check for the garage: Ask by VIN about an outstanding campaign; with knocking or the oil warning, stop. Check the catalytic converter if there is hesitation or loss of power.
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.

Coolant, oil, steering joints and recalls on the i40Known weak points

Engine / equipment: Hyundai i40, petrol and diesel
Period mentioned: 2011–2019
Symptoms: Coolant loss, mainly on the diesel; above-average oil leaks from engine and gearbox; battery (2011–2014); at the roadworthiness test, steering joints, scored discs, rusty brake lines and lights.
Possible cause described: The cause of the coolant loss is unclear (internal leaks are suspected). There were engine failures that Hyundai fixed from 2013. Recalls: a 12 V socket that overheats with the tyre-repair compressor (a fused extension lead is added) and a clutch switch that could allow starting without pressing the pedal.
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.
