Installed IPSM and took apart the old module. I found on fuse with a over heated blade. Fuse was good, but one leg was over heated. I check the circuit board for burn marks and nothing. Not burnt smell ether. I did how ever notice what looked to be water marks like water ingress had taken place at some time. No mold or corrosion though.

I am working on running the car at idle for 20 min and then let it sit for some time then firing it up again. see if the no start is still present.

Integrated Supply Module

I am sure that you have already fixed this issue but I had the same problem. I tried a number of fixes before I replaced the integrated supply module. Once I did that I haven't had a problem since.

After a week of driving not issues with the car . Shifting seems to have improved as well. Going to try and have the software in all modules updated next week.

Car shuts off

It's some kind of module that needs to be replaced. The price goes from 120 for the part. That happened to me as we'll.

For those that have changed the IVM (Integrated Supply Module); did you disconnect the battery first? Going to be doing this very soon and don't want to kill anything! Thank you!

Confirmed; unit swapped out with battery connected. No issues before, during and after installation. Now I hope that it takes care of the no crank issue!
