My 2020 Ram is experiencing what seems to be some kind of computer system crash where my entire infotainment system goes black and goes through a nonstop series of rebooting then crashing, and while this is occurring various random things don't work, such as my front driver and passenger windows (but backseat windows work), AC doesn't work, etc.
This started a few weeks ago when, out of nowhere, I got a message on the console behind my steering wheel showed a message saying "Blind Spot Alert Unavailable Service Required". While this warning was on, my blind spot alert indeed did not work. I got to where I was going, turned my truck off, and when I got back to my truck to drive it again the message was gone and blind spot alert was working. Then, a few weeks later, this past weekend, I was driving and the message came back, except this time it was followed by the whole computer / infotainment system crash and all the random things in my truck not working. During the crash occurring, where the infotainment system just constantly crashed then rebooted, that same "Blind Spot Alert Unavailable Service Required" message continuously kept coming and going. I performed a full vehicle reset by disconnecting my battery's negative terminal and reconnected. This actually rectified the issue, but only for 48 hours, and now it's doing it again.
Just wondering if anybody has experienced similar issues and has some input.
I thought of trying to check what software is on my infotainment system and to see if I need an update, but I don't know how to check what software is on there, and I also don't know how to get the most current form in a manner to download it directly from a flash drive rather than have to rely on the over the air updates. If anybody has ideas on how I can do that not over the air with a flash drive, I would greatly appreciate your input on how to do that.
Thanks! (Truck is out of warranty, FYI)
FWIW: AlphaOBD indicated it is throwing the following codes:
U0010 (fault in can interior bus)
U0011 (can communication interior bus performance)
U0164 (lost connection with HVAC code)
U0200 (lost communication with door control module)
After clearing the codes, the only one that comes back immediately is U0010.
