There's been quite a few discussions on Warranties on different car forum's.
Some owner's who have tried to claim discover that the Warranty does not Cover what they're trying to claim on.
And some have suggested creating a Bank Account specifically for your car , preferably one with an interest.,???
I have a 2 year warranty not a jaguar one with my XF and we'll see if i have to make a Claim if they will pay out.
You should Google Car Warranties and you'll find out what is on offer.
