started to turn on all the dash lights randomly, it turns on headlights, turn signals and even the wipers
These circuits are controlled by the BCM and can exhibit strange behavior if there's any main battery issues. Did they report any diagnostic codes being logged when they checked the BCM? Did they load test the battery for any shorted cells?

With 40+ electrical and communication codes there's a problem affecting the CAN Buses (controller area network) and power distribution. It could be the TIPM (Totally Integrated Power Module). Essentially it's the fuse box. There's a front fuse box (engine compartment) and a rear fuse box (trunk). There's companies that sell rebuilt TIPM units. You can do a web search on "TIPM".
You can check underneath the front fuse box for the condition of the wiring harness/connectors. Do the same for the rear. But if the problem is internal to the TIPM then you will need to replace it.
