My 2013 F350 CC Lariat with 16,500 miles has developed a TPMS problem. Tire pressures are at factory specs, checked regularly and rotated at 5000 miles. I have not had any issues until now. The alarm went off a few weeks back as I was driving. I checked the TPs and they were good. The truck sat over night and in the morning I went to work no TPMS alarm. Went like that for a few days then an alarm. TPs still good. It has been going off intermittently now and it seems like when it is cool it won't go off. I tried the learning procedure by the owners manual and I can't get past the first tire. I bought a Ford TPMS training device and that won't work either. I went to work Yesterday morning no alarm I was driving along and turned on my radio and the horn beeped and a message came up LEARNING PROCEDURE FAILED TRY AGAIN, now my radio won't work. GPS, Climate, and Phone all work on the touch screen, no radio. Anybody have this happen?

My 2011 had a warning of TPMS failure, not low tire pressure. That occurred while truck wheels riding on the side road rumble strips, with severe vibration.

But at same time wife was charging her Apple Ipad.

Occurred a few more times while on RV trip, but cleared, and tire pressure good all around. I decided to have checked, had the Ford clicker check. All checked OK.

Then later while checking online, found the issue may be the Apple charging of an Apple product, be it cell phone or Ipad thingie.

Hasn't happened again, since told wife to not charge her Ipad. We charge our cell phones, Samsung, OK and no TPMS faults.

As for radio bit, don't have that fancy display, so can't comment on this puppy. My guess, maybe some kind of RF interference. Or a EMP device went off in middle section of country....
