Hello there, I've been experiencing a problem with my 2011 FFH (65,000 miles) where I unlock the car just fine with key fob and then when I get in and attempt to turn the engine with my key I lose all power to the dashboard as well as any functionality to the dashboard. I noticed today that when this happens the Airbag light on the dashboard blinks repeatedly. I've tested the battery and it's totally fine and very recently replaced as well. I've been driving around town and had this happen to me multiple times where when I leave the car and come back there will be no power and then if I wait 10-15 minutes it miraculously has power again. Anyone have any idea what the issue could be here?

I've had my FFH-SE for almost a year now and have put about 5k miles on it. Its a 14' with 75k miles. Everythings been fine except its been acting a little strange sometimes. Occasionally when I'm parking the vehicle (I always use the parking brake) I come to a stop, put the vehicle in park, activate the parking brake, and turn off the vehicle. After that last step, sometimes the car will completely power off and will not enter retained accessory power mode (ie radio and windows still working). If this happens I usually start the vehicle again. When I do I notice that my settings are back to default and the AM radio is on. Also the start-up chime sounds old (the "duu-daa-dum"). And a message will pop-up saying theres a parking brake fault and to get service. I disengage the parking brake and everything fine again. Another time I was putting washer fluid in and I left the driver door open. After I finished checking fluids and such I came back inside the car and notice that everything was off. Like everything. After slight panic of not even knowing how to open the trunk in this situation (to access the 12v batt). Everything came back on and was on default. Other times I will start the vehicle from a being away from it for 8 or more hours and the wrench light will come on as soon as I start it (has only happened twice). I can usually get the wrench to go away by cycling the power a few times. Anywho all of these things have been happening in the past few weeks. Now that I've wrote this all down I feel the 12v battery may be the issue so i will get that tested now. But does anyone have anything to add?
