08 Z06 multiple Codes/engine trouble
Just purchased an '08 Z06, and having major issues with it. The car starts fine when it's cold, but once it's going for a while, I lose my air conditioning and multiple codes come up. When the car is hot it won't restart. Once it cools off it'll start again fine, but all the same error codes appear. Also having 'low fuel' appear, even with full tank of gas. The error codes I'm getting are:
P0496 EVAP
P0336 Crank Sensor
P05575 Cruise Control
P0856 Traction Control
U0073 Data
P0420
P0430
Could there be a single cause for all of these issues, or am I looking at multiple problems with the car. Any guidance/advice would be appreciated.

With the U code which means a loss of communications of the can bus with the control modules, I would think that yes, there is probably only one thing causing your issues, but which one.
Is the battery OK; load testing should be done. Battery cables, ground, positive to the starter, which can be a issues with the solenoid melting and creating a loose cable connection. Crank sensor error could be a cause, as when they get hot they are know to not work, causing a crank but no start condition.
But more than probable is one of the control modules and/or sensors could be plagued with dirty/corrosion with the pins inside of their connectors. The engine harness has about 8 grounds that could be a cause.
Maybe bring your car back to selling dealer, if that's were you bought it from.

Welcome, I see this is your first post. Unfortunate things happening w. your new Corvette. This has been covered many times before and above post as well, but to quote extra above,
"...I would think that yes, there is probably only one thing causing your issues, but which one.

All heck breaks loose when the batt. goes---so, get it load checked by a competent store for free(usual). Then, all cables, all grounds esp. at batt. and starter. Get back to us when you've done that and see if it helps/cures issue. I hope it works out to be "just" a bad battery, or cable connection.
Read over the many threads in here, not just for Z but C6 Gen. via "advanced search." I'd say you will find just about every issue, trouble, mod, etc. covered over the last 9 model years of the C6.. If not, yours will be a welcome addition.
