 Ever wonder why Ford only gives a 65k power train warranty?  I'll tell you why.  Because at about 70k miles you start to have all sorts of problems with your engine.  A month ago, my truck started to run very rough out of the blue, so I took it to Surprise Ford and was told I need new spark plugs and one new coil to the tune of a little over $800.  I told them that was and I would get other estimates which I did that were all at half the cost of them.  they said they would price match and since I was told by the service advisor at Ford that these eco boost have very tricky plugs and that even their seasoned mechanics drop about 1 out of three plugs into the cylinder heads as they are a two piece plug and if you dont take them out right they will drop and you have to have a special tool to get it out of head, I let Surprise ford do the job.  Well I get the truck back and notice that my fuel mileage is getting worse.  I only put about 250 miles on it in these 6 weeks so it took me a while to figure this out.  I was going to call the dealership and take it back to them to find out why this is happening and also to figure out why I also now had a pull to the right on the steering which wasn't there before.  Its monsoon season in Az so I figured I would go wash the truck and get it to the dealership on Monday.  Low and behold I was driving home from the car wash and I hear a loud pop like something exploded.  I notice smoke coming from my engine compartment and guy next to me is yelling at my saying my truck is on fire.  I pull over and get my 8 year old son out of the truck and to safety.  The fire went out and only did some damage to the under carriage.  I have it towed to Surprise Ford.  This is on Saturday Night.  Wednesday I finaly get a call from the dealership saying I need a new engine because there is a hole in the block, but can't say if it threw a rod or a cylinder exploded, but in any case its not anything they did and now they want around $11,000 for a new engine.  ARE you kidding me?  Never again will I buy a ford.!
