    The Horn stop working! The car sat for about 4 months because of COVID-19 here are the codes the dealer gave me! They told me the horn needs a new horn ECU replaced to make it working again! Yea there are no lights on the dashboard bc the cluster is fried most likely! I cannot do anything with navigation screen it was blank! The Radio wasn’t turning on either! 12V Was Dead! I also need a new ECU for hv battery as well they said! The fan was pretty loud in the back near the 12V! Any ideas on what to do?

    Does the car run, after replacing the 12-Volt battery?

    Was the car "jump started?" How did it get to the dealer?

    Stated in past tense, so it won’t be the 12v battery anymore.

    99k :whistle:

    A drained 12-Volt will set all sorts of codes, with many re-initiaizations required.

    I had a strange issue when my 12v battery was going. The car was going into safety mode (orange light on the start button and all the warning lights illuminated) and wasn't going into drive mode. I eventually realized it was the damn battery and stopped getting stranded places while waiting 20 mins for the car to actually start.
