My 09 MDX was parked while I was at work, and I go to get in it afterwards and it unlocks fine with the fob and then when once I turn the key to start the car it starts fine for like 30-45 seconds and then it just dies and the green key immobilizer light, oil light and battery light flash and then once I remove the key they all go off. HELP?! What's wrong with it. I tired with another key and the same thing happened. I don't know what to do!
