Took my XF in to the dealer yesterday - drivers power seat stopped working.
Interesting problem; how do you get a seat out of a car when you can't move it? That's their problem, but they told me it would be $360 to remove the seat and they needed authorization in case it wasn't covered under warranty. Humm.... how could it not be covered under warranty I asked?

If it was a frayed or broken wire, they answered.

Hopefully I will find out tonight. They said they hoped to have it fixed today, good thing they provide a rental car when the XF is in the shop for warranty work.
