I just picked up my 2021 Ram Laramie Sport on Tuesday December 8th, I ordered the truck from the factory. On Friday with just 68 miles on it the backup camera stopped working. I have the 8.4" display. I have the most up to date software which I confirmed. After reading some of the threads, I tried the suggestion of disconnecting the negative battery terminal for a minute, then reconnected I started truck put in reverse and the camera is working again. I had an appointment to take it in but cancelled. Told the service advisor I would wait to see if it happens again. No point in taking it in for the to tell me it is working now. But the bottom line after seeing how many people have this issue, there is an obvious glitch in this system and it needs to be addressed and we need to be updated as to what is being done. I have always purchased Chevy trucks and cars as my brother works for them and I can get employee pricing. I bought the Ram since they offered employee pricing for all.
