I just purchased a 2010 FX 35 AWD that I am thrilled with...except for today! I was setting up my nav and phone in my garage with one overhead light on. I was in the car about an hour when the nav went dark and all the interior lights started flashing. I tried to turn off the light and turn the car to off but nothing would work. The headlights were flashing but nothing I did would stop it. Within a couple of minutes the driver side headlight completely dimmed while the passenger side stayed bright. It was like the car had a stroke. I tried starting the car, using the mechanical key to lock and unlock it, but nothing worked. There is a red flashing car on the dash which is still flashing. I knew the battery would just die. I left it for about 45 minutes and the one headlight went off and the other stayed on. I tried the mechanical key again and the lights went off but the car won't start. The starter button does flash so the battery doesn't seem to be totally dead. Is this an alarm issue, battery, stroke, what?! Help!
