So whatever the dealer did last night allowed for an OTA update this morning. Not sure this will fix my audio problems - will see. Anyone noticed any differences with the new software?

The infotainment is up to date. Dealer installed when I switched to winters in Oct - the radio started really acting up after that. It had just been released. H264 was done by dealer in the spring.

Yeah I noticed that battery management is behind. I wonder if that will come OTA now? Anyway they're going to replace the IMC and I was told would have to update all the software. 🤞

Interesting. I have now had a few isolated incidents where the audio system completely cuts out (all audio,, from any source) and/or the backup camera stays on after pulling away.

I'm wondering, did your issues get worse over time? Or was it all at once? Having seen these initial episodes, should I be anticipating continued deterioration?

Thanks.

My problems seemed to occur randomly. They were a bit less frequent recently. This week the IMC (infotainment master controller) was replaced and everything seems to be working correctly. The only thing with the software is I can't tell which version of the battery control software is installed - shows blank now. Here's the invoice below. If this is the end of the gremlins I will likely buy the car out at the end of my lease.
