What would it cost to fix this?

You can take the VIN to the dealer and they can tell you what has been done and what was missed... This is nice and accurate information since Land Rover pays for the maintenance up to 50k miles... Here is a link for a .pdf of the maintenance schedule;

I don't think it matters if the vehicle is still under warranty since Land Rover only pays for the first 6 services... the 60k would be on your ticket...
