I Purchased a new Ford F25 Super Duty Pick up. It was the First Ford in the famliy for gererations.
At 67000 miles the truck blew a sparkplug completely out of the cylinder head, stripping the threads on the head, not the plug! It cost me 3000.00 because Ford said that they wouldn't do anything about it. I contacted Ford Customer Service and they completely denied ever hearing of this. That was a lie.
Check out http://www.consumeraffairs.com/automotive/ford_spark.html to see how many other "satisfied" Ford Customers there are with this problem and how many were told that the problem was unknown to Ford. No wonder Ford is in financial trouble.
DON'T EVER BUY A FORD VEHICLE.
