Just personal,
but from my experience I would avoid Hyundai iX20 like the plague. Had a new one and it spent 12 out of the first 26 weeks at the dealers due to inability to source new brake calipers. Indicated to me that they are OK until someting goes wrong, and then the (outsourced) warranty group was/is not capable of dealing with problems on even the simplest of parts through the dealer network. Also the ride was harder than the B-Max.
Got rid of it after six months and went to a (manual) B-Max, and am on my second now. However I agree with comments about avoiding the Ford small gearbox as it causes problems on the B-Max, and apparently also the Fiesta and Focus.
