2012 Sync does not work when hot

wreedps · Jul 13, 2015

So twice now I have left my truck in the Houston sun all day and when I crank it up around 5PM my Sync acts all wacky. The Voice button on the steering wheel is basically unresponsive and if I get it to do anything she moves very slow and hangs for a long time. Such as ending a call, the radio will hang on "CALL ENDED" for 10 minutes or so.

Once it cools down(which is the only thing I can relate it to so far) she works fine.

Going to work in the morning when it is 75F it works fine.

Anyone ever had this problem before? It has just started this summer.

Truck has stock radio setup with 50k miles.

No one has seen this before? Is Sync a separate module from the radio?

Happened on my sisters focus. Ended up needing a new brain.

Where is the brain located?

Jomax · Jul 15, 2015

Behind the screen I believe.

I am going to try to update my SYNC firmware tonight also.

Just did my 2012 in 20 minutes. It now defaults to bluetooth if you turned the truck off with bluetooth playing! awesome!

Mine does too but it won't play music through the USB anymore, i can watch the track play on the counter but no sound from the peakers...just on USB. I had the dealer update with IDS.
