On my 2006 at 52K my battery charge light would blink on and off during normal operation. My cruise control would also drop out at random times. I was about to check voltages but before I could get to it the car died. I was coming up to a traffic light, failsafe mode came on and car died. It would crank but would not start.
Had a CPO and problem turned out to be a shorted ignition switch P/N 61-32-6-901-961. This happen Dec. 2009 and machine has been running great since the failure.
