Talk to a dealer service rep there and tell them the year and mileage of your VX and the problems you have.
It's all iffy according to who you talk to and how helpful a dealership is when it comes to warranty work. My guess is that they will want to see the truck first before doing anything.
Good luck..
What dealership are you going to? Maybe there are other VX members here that frequent that dealership. You could mention their name(s) when you call. Couldnt hurt...
