What or why does Ford not know how to put a stop to this problem. I have had 3 turbo replacemnets in 12000 miles. They changed the type turbo, but I found someone who has ahd 6 changed with 2 of the new. I only got 1000 or less miles on the last one. Fords only comment is it will honor 100000 mi warranty as many times as it takes till it is reached. Does anyone know anything on this subject as we are stumped.
