The steering wheel is just a little bit stiffer when turning left compare to turning right. Its not very noticeable. But I'm just wondering if anything could be going wrong

 

Eenie meenie chilli beanie, the spirits are about to speak! ...
And the year, model, etc. of your vehicle is ?

*Telepathic or Karnak we're not.

If it's under warranty ( 3year/36,000miles | ESP ), what did the FoMoCo service department say?

You obviously need to take your truck back with as many problems as you've posted!

 

Why would it matter EPAS has only been used since 2011 and newer

 

Sitting still or at speed?

 

+1...I looked at all of his posts............kind of strange how all of his 19 posts are complaining about some aspect of his F150.......there must be SOMETHING that he likes about his truck, or it must have been some kind of weird test drive!!

 

DAH! Year, mileage, etc. are pertinent ... i.e. a 2011 with skatey bazillion miles obviously would be out of the bumper-to-bumper | ESP warranty range -AND- mileage could also mean an out-of-the-ordinary issue with the electric assist power steering -AND- it could (not saying it is) a year-specific TSB and/or issue (after all ... 2011 WAS the 1st year for the EAPS).

SOP - The 1st bit of information in any diagnosis should be that of the vehicle. UNLESS you're playin' 20questions.
