Not a normal behaviour and most likely not related to the firmware unles the update didn't end properly. Uconnect doesn't have any major software related issues Under the 2 or 3 latest versions.I have noticed several things that now happen after the last update.
A couple of times the radio would not change stations. Within a minute it did change, and since I hit the button several times, it's then changed several stations.
Another thing happened, as we pulled under a drive thru, not only did we lose signal ( expected ) but we lost the entire screen image on both the radio and the main dash. Nothing but a black screen on both until we pulled out from under the roof.
The bluetooth disconnected once. I simply reconnected the phone to the car via the UConnect screen and it is hasn't done that since.
Since I don't drive this car all the time and my wife really doesn't notice small things, I can't say if any other issues have surfaced.
