My car is the coupe, cranks and idles, but then just shuts off, everything on the combo meter stays on. I used a scanner got the u1001, p1212, p1610 and p1612 codes. Any help is greatly appreciated.

Hello,

The u1001 is the big code here, it means the computers are not talking to each other so one of them is down. The main cause for this is a fuse being out. Here is a guide to help you check the fuses and their locations (below)
