What hardware/software versions do you currently have?
I started with N0GL hardware and 18.45.40 software, never had an update since new.
I’ve come across this problem with my truck as well. Everything worked great for the first year I owned the truck. The only thing that changed was my SiriusXM Guardian services expired. I was gone for a week for work when it expired, but the first drive after I got back is when it started happening.
Every 3 1/2 minutes the Uconnect system would shut down and restart. Tried some of the recommendations found in the forums here...unhooking the battery, pulling the radio fuse, unpairing my phone, unplugging the cord used for apple car play...all with no change. Still reset every 3 1/2 minutes.
5 weeks later, and I think it is fixed. Here is the story:
Took it to the local service center a couple days after it started happening. They diagnosed it and couldn’t fix it then/there. Said it would likely need a new unit but that had to be authorized by Uconnect or FCA first and they would get back to me. Reached out to Ram Cares to start a case with them as well. Also noticed the Nav was showing an incorrect position and didn’t have any satellite signal. At first it was just a few miles off, but slowly got worse and then it ended up in the ocean on the other side of the world. Due to no GPS, the clock was always wrong.
A week later, the service center called and said they had a new software update they need to try before the new unit was authorized. Brought the truck back in and found that the update “didn’t take” and I was left with the same software/hardware and problem that I had before. I was never told what version they were trying to update to. About this time, the battery started going dead when the truck was left overnight. Called in to the service center and they said it was due to the radio resetting even when the truck was off. Never noticed screens turning on and off while it was shut down like other members have complained of though. Tried to manually set the clock, but due to the battery going dead and me unplugging it every other night and charging it, I would have to reset it every time and just gave up on that.
I had hoped for an over the air software update would fix the problem, but it never came. A new unit was authorized and ordered after the software update at the dealer didn’t take. About 3 weeks later, it arrived at the dealer and was installed in about an hour and a half. Drove home and the radio didn’t reset at all. Didn’t have my surround view cameras, manual step deployment, climate controls were messed up and would only go to hi or lo (no temp preset available). Sat in my driveway for about an hour and started it up and all is working and back to normal. Now have NFFL hardware and 19.43.13 software.
Sorry for the long read, but hope some of this info helps you or someone else here. Good luck, keep on the service Dept and get Ram cares involved and it will get fixed. I know it’s frustrating, but there is a fix. Good luck.
