I wouldn;t take any notice of Kia's so-called warranties. My dealer refused a warranty claim on a bonnet clip which seized up and froze the bonnet shut just in time for MOT at about aged 5, well below the 100k miles.
They claimed it was on account of "incorrect maintenance" blaming me for not greasing it often enough living in a coastal area (

- pull the other one) and stung me for over £200 in parts and labour to get it through its MOT. Usual story. The joke is the car was bought & registered in coastal Devon but serviced and kept inland most of the time 100 miles from the nearest salt air.
An even bigger joke is that the very same dealer had fixed the front of the car under insurance after some idiot reversed into it in a car park 2 years earlier. The bonnet clip never worked again properly after that without sticking so it was their own shoddy work which was to blame for the premature failure in the 1st place.
I've said it before and will say again, warranties are barely worth the toilet paper they are printed on. Most of the time you may as well buy at a 40%+ discount from abroad if you can and pay for the odd repair if needed. Save yourself the grief of arguing with a load of lying, cheating b******** along the way too !
