Start off by saying that I have been a ford customer since I was 18 years old. I am 62 now. I recently purchased a F150 XLT bought the Platinum extra warranty. about 20000 miles started getting a noise that sounded like the beginning of spark knock. It has a 5.0 engine. I had them check it out and they said they found something and changed a part. Went in for my next service with same noise and they said to run a higher octane fuel. I did that till the next oil change, still did not work. They looked at it again and they said that Ford put out a bulletin that the 5.0 has a noise at low acceleration that sound like a typewriter. THATS NOT GOOD. Salesman told me if it gets worse bring it back in so I did. they give me a print out stating there is nothing that can be done. I came home and called ford customer service and they opened a ticket and told me to take it back, I did and when I got there the service manager came out and said Ford was suppose to call me off and say that there is nothing they can do again. Ford can do something about this since they know that it is not right. they said all 5.0 motors have this issue. I don't know about you but I did not pay 46000 dollars for a type writer. Ford if you would like to talk about this and change the mind of a true Ford customer you can call me off of the case number you give me 44673783 or don't call and have a very unhappy customer. Best advertisement is word of mouth.
