Build my inspection planPractical and cheap, but check the GDI engine history carefully.
GDI rod-knock and catalytic-converter failures; confirm any recall work.
Extended powertrain coverage applied to many affected engines; verify it.
The 1.6 CRDi is generally robust but suffers from EGR valve carbon build-up and DPF blockages if used primarily for short urban trips. Check the service history for regular oil changes to protect the turbocharger, and ensure there are no hesitation issues during a test drive indicating soot accumulation.
The first-generation Soul EV can suffer from battery degradation, reducing its already limited range. The On-Board Charger is also a known failure point, preventing the car from accepting an AC charge. Always test both standard AC charging and CHAdeMO rapid charging during a forecourt inspection.
All internal combustion engines offered in the UK 2nd generation Kia Soul, including the 1.6 GDI petrol, 1.6 T-GDI petrol, and 1.6 CRDi diesel, utilise a timing chain rather than a cambelt. These chains are designed to last the life of the vehicle, provided routine oil changes are maintained.
