- 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).
