Hi Mick, definitely let us know how you get on with that. I tried contacting Hyundai as well, and they said they may be able to offer goodwill payment, but when I told them I didn't buy directly from a Hyundai dealer, they didn't want to know.... surprise, surprise. Even though we bought the car when it was 7 months old, and had it maintained and serviced at all the correct service times etc.
It's a bit of a joke having pay so much for something so small. Our car only has 42,000 miles, so even less than your car, and still these lights have failed.
I've not really had any issue with our i40 apart from this, so it's a real kick in the nuts when this sort of fault occurs!
Thanks for replying anyway, and as I said let us know how far you get!
