Truck has a rattle/tapping noise in left rear of cab coming mostly from supercab door that occurs on certain bumpy roads and turns.Noticeable especially on colder days and at night.Brought it to Levittown Ford for diagnosis/road test with the shop foreman,he heard it and only replaced a small piece of weatherstripping that was taken off before I even brought it to the dealer in the first place-meaning IT HAD NOTHING TO DO WITH IT!!. They then say that this is "NORMAL" condition and that they are not going to do nothing else.Normal?-really???rattles and ticking in a brand new $43000+ Lariat F150?-WOW!. Contacted Ford customer relations and said they can't do anything except leave a bad feedback for dealer and for me to get a second opinion from another dealer:(disappointing since the dealer claimed "THEY FOUND IT!" and the shop foreman told me to have "faith"-are you kidding me!?. Stupid,unprofessional dealer with no real regard for customer concerns or issues with their vehicles-meaning AVOID!!!. Let's see what another dealer says and if they think it's "normal" too.Unbelievable.
