The 370z uses a keyless ignition system. The system failed and I am no longer able to start the car. I am being told by the dealer that it is the electronic steering lock system. There are many many other 2009-2010 370z owners that are experiencing this same issue at aprox 30-40k miles. This appears to be a manufacturer defect.
