 I had my vehicle in the shop within a month. After multiple visits and attempts to fix the problem Ford Corporate said my noise "was a characteristic of some Escape and Mariner models," "there are things to be done to temporarily fix the issue but it will continue to be an annoyance for the customer." Reference Special Service Number 21233 (if you can find it). Ford cannot fix problem and will not replace the vehicle. My Ford is now a very expensive POS. If you happen to buy the Lemon on the lot, be ready for a huge headache.
