So many of those symptoms are identical to those I had when my DSC module failed. Perhaps your model hasn’t failed (hence no trifecta), but there is a communication issue to/from it with a harness or connector?

My AC and blower were dead
My speedometer was dead
Transmission failsaife mode activated
Almost all of the same timeout codes were present
Pegged temp gauge
Strangely, my aftermarket backup camera that I installed stopped working. I’m assuming because the circuit/fuse I tapped off of in the trunk went dead

It would run fine for a few miles and then all the above would appear, presumably as it warmed up and something shorted internally. I didn’t have the wheel speed sensor codes though. Long odds that they both would fail at the same time. I’m still thinking your DSC module or wiring harness is failing.

I had no luck with eBay modules and had to buy a new one. Fortunately they are still available, but not cheap. Hopefully you can find an x5 or two in a junk yard and yank the modules. If in fact it ends up being the DSC module.
