Thinking about it, an insurance claim is no good as you’d have to pay the excess. It’s a shame that you have a poor dealership. Our local Hyundai dealership is brilliant. They paid for all four alloy wheels to be refurbished on my daughters (private) i20 in its 6th year, after the 5 year warranty had ended!
If snow caused that it has to be a design fault. It’s not acceptable to say that a car shouldn’t be driven in snow. I’ve had times when I’ve been away from home when it’s snowed and I’ve had to drive home in it. I doubt that the dealership would offer to pay hotel charges to save you having to drive!
