"Not talking" sounds like there's an issue with the CAN (controlled area network), which links many of the control units together via two, twisted wires. One would need a lot more information to help you with this, including trouble codes of various systems. The first thing I would do is see if it might be covered under warranty, since powertrain is 5 year/60000 miles and long-term emission system, typically 7-year/70000 miles. Of course, start with your basics, including checking fuses and fusible links, making sure battery connections are clean and tight, charging system is within specs and checking the trans fluid level and condition.
