I had this issue on my 2013 Sport last week and had read up on it here prior to taking it into a major dealer here in the KC area.
I told them....Here ya go....This is 13N02 Extended Warranty on Brake Booster. (2010-2013 Model Year it says)
They checked it out and yes this is/was the problem.....However
They said my Vehicle was not covered due to not showing in their system by the VIN. It would NOT be covered...
Welp a 2013 Sport that will not stop does me no good.
"Fix It"...It was to the tune of $617.85.............
To me this is a major safety issue on the vehicle and not covering a known defect can kill people.
I wish an accident is what brought me to them.....Like thru a dealers showroom window....
M-F'ers ...Maybe it will fail twice...I should test this theory tonight with them!!!!!
Soon.........This Edge will be owned by some other sucker....Bye Bye Ford!
