Numerous electrical issues

[simpson]

I traded in my '09 for a '14 1500 about a month ago. It is a big horn with navigation (I believe that means I have 8.4AN). In the next week, I had numerous issues including:
1. Service Tire Pressure System (no reading for any tire).
2. Clock would lose time. Didn't matter if the 'sync with gps' was active or not. Either way - it would lose minutes.
3. Service vehicle phone. This would then show a red light on the rearview mirror by the Assist and 911 buttons.
4. Navigation would get lost. It would show me driving in a lake or on roads that were about an hour away.
5. Keyfob would not work unless you were within 3 feet of the truck. Remote start would not work at all. Replaced battery but did not improve results.

It has made a few trips to the local dealer (not where I bought it though) as it is still under warranty. They tried a few things that worked for a short time, then ended up replacing the R/F unit. That worked for a short time, but then same problems starting occurring again. They also ordered a new key fob, but it has the same issues as the other fob. They just replaced the radio (not sure what parts that all include) and everything worked....for a day.

Looks like some of the problems may have been corrected, but not all of them. Current issues:
1. Keyfob only works when you are very close to truck, although batteries are fine.
2. Service tire pressure system (does not give a reading for any tire).
3. Not sure if this is related, but with new radio - I had sirius stations. I assumed this was a free trial period (as this has happened on previous purchases), but once the above problems started happening - I no longer have any sirius stations.

I just looked at the software version and it shows 15.26.1
I don't think that is the latest, but not sure if an update will fix everything or if I should even attempt it. Dealer has had it about 4 different times so I am thinking they need to figure it out! Willing be calling them soon.

Any suggestions/input???
Thanks in advance!

I am not sure I can help, but lets go over some basics.

1. How many miles on truck? Where did you buy from?
2. Does it seem that the truck was modded at all?
3. Does the truck have factory tires/wheels and suspension?

I would try the update just because it may help.

26k on the truck and she is all original. Bought from a ford dealer (about 100 miles away) but being serviced by local Dodge dealer.

I had my 8.4n radio on my 2014 updated under recall recently and 15.26.1 is the current version.
