I have an issue with my 2019 RT Ltd. It wouldn't start the other day. Now there's Nothing, no gauges, no lights, nothing. I tried a similar battery (250 CCA instead of 350 CCA), and the gauges light up, horn worked, but no starting. It does not even turn over. I expected that. I put in another battery for a test, this time it was a 320CCA, still not 350CCA but close enough for a test. Same result, gauges light up, horn works, no start. This time I noticed I could remove the E-Brake but now I cannot put the E-brake back on. I checked for error codes, and this is what I got... "U3E0C and U3001". What does this mean and is it the root of all my problems? Please advise if you know what it could be.
