CT200h driving mode errors and unresponsive system

I'm having a bizarre issue with my 2017 Lexus CT200h hybrid. It's got 175251 km on the clock. Lately, I've been getting sporadic error messages about the driving mode, and sometimes the error lights just light up randomly. Even weirder, the audio and navigation will sometimes just die, or the whole system becomes unresponsive for a bit! I scanned it with an OBD-II reader, and it's throwing all sorts of control module errors. Anyone else experienced something like this? It's driving me crazy!

I also drive a CT200h and recall reading something about similar problems. If I remember correctly, it may have been related to a BUS system connection.

BUS system connection? Could you elaborate? Where is that located, and is it something I could check myself?

Unfortunately, I do not have specific details about the BUS system, as I am not a professional technician. It would be best to take your vehicle to a qualified workshop for diagnosis and repair.

Thanks for the suggestion. The workshop identified the issue as a defective cable connection to the BUS system. The repair cost 155€. It is working well now.
