Anyone have issues with (wrong clock time) this on their 2015 with Nav?

My truck does sit for a couple of weeks at times, and this morning the clock was off by almost 50 minutes. The truck fires right up with no hesitation or slow cranking. It is parked inside. This is twice this has happened. I don't know if the battery is draining below some voltage threshold which affects the clock, but maybe.

Press the 'sync to gps' and it updates to the correct time (except that Ford still has not fixed the DST issue. Really? How hard can that be?

 

I just bought a 2015 F150 Lariat 3 weeks ago. The clock loses time constantly. I will program the clock and after sitting in my driveway for a couple days the clock is behind real time. Today my clock is 46 minute behind after sitting in my driveway for 3 days. I'm going to the dealership to complain. Anyone else having this issue?

 

My wife has a 2013 Cmax and hers does the same thing. I think it is a glitch in the SYNC system. Hopefully they will offer an upgrade when the new SYNC comes out next year.

 

my 2013 Focus ST does the same crap with Sync 2. buggy Microsoft piece of junk, one of the main reasons I didn't buy a 2015 F-150 and am waiting for 2016+

 

After sitting for 5 days, my clock is now 34 minutes slow. Battery voltage was checked and is at 12.6, basically fully charged.

Guess it is time to go to the dealer.

 

Sync won't get anymore upgrades. They fired Microsoft. Only way to upgrade is buy a car or truck with sync 3.

 

My 2015 F150 had had this same issues for about a year now. Dealer has checked everything they have no idea what the problem is.

Taking it in next week, told them to keep the truck until its fixed, oddly they agreed and are giving me a new truck until mine is fixed. I think because I have taken it in to fix this issue 4 times now, with no success.
