What year and engine is your car?
Mine's a 2014 and a diesel (still manufactured in the same plant but the engine is different). I started a second thread (
Link) after I had another fun time earlier this year, though I only had 6 codes.
I tracked the latter set of problems to two issues:
1. There was a dodgy relay in the front fuse box which I found by moving the relays around and tracking where the error moved to (inside the lid of my fuse box it has details of the circuit that the relay handles). I didn't have a relay tester to hand otherwise I would probably have tested the relays out of the car first. In the end I got the relay problem to the AC circuit and replaced it for less than the equivalent of $10
2. On my car there are two big connectors for the wiring looms which sit towards the back of the engine bay (example in photos below). I disconnected these, cleaned the connections and reconnected them; I believe there's another one down somewhere by the transmission. I saw a video (which I can't find again at the moment - sorry) about a Ram truck with a strange set of electrical communication issues which was tracked to one of these connectors. That inspired me to try the same. The mechanic in that case recommended cable-tying the two halves together to make sure you get and keep a good connection. I haven't had to do that yet.
I have heard of bad earths causing problems (are you in an area with salted roads in the winter?) and failing alternators (there was a recall on certain model years at one stage), did they test yours or just read codes?
