Jumped back in to leave the store, the vehicle would not start?

Is a CAN Scan different than a Network Test/All Module Scan? If not, then I just have the five codes that came up during my test drive.

I would like to test the gauge cluster next and continue ruling things out. How can I test the gauge cluster beyond the gauge cluster self-test, which did not result in any errors being reported?

Sounds good, I will try to find someone to test it.

I have not been able to locate someone to send the gauge cluster to for testing, beyond taking it to a dealer. We decided to just start driving the vehicle to see if we have the issue come back. So far, we have put a several hundred miles on the vehicle without having any trouble. I am going to continue to monitor the vehicle. Thank you for your time and help.
