I also have a 2011. Can anyone provide me with the TSB info that justcozz is referring to? My reservoir was topped off and I'm driving my truck as is since the service adviser at my dealership told me that they spoke with their manager and they couldn't get the repair approved under warranty. Since it's a very slow leak, I'm just going to see if my customer service case amounts to anything.
I understand that wear items are excluded, but the 2011 Ford Warranty Guide DOES NOT specifically state hoses as an example and adds that exclusion from coverage is usually due to not being able to associate the problem with a potential factory defect. I've had vehicles from other brands with over 100k miles and no hose replacements necessary. I can't imagine a hose failing in 30,000 miles without there being some sort of manufacturing flaw to begin with. My servicing dealership is also not my purchase dealership so I'll probably talk to the dealer I purchased from to see if they have the same opinion on warranty coverage.
If I had been outside of warranty, I would have just told my dealership to do the work in the interest of my time. I am, however, within both the bumper to bumper warranty and powertrain warranties so I simply don't agree with paying for this repair. Worst case I'll just find the time to do it myself if nobody from Ford or a dealership can step up to support their product. It's just wait and see right now.
