My 2010 with 129900 miles has been great, even without being driven much lately. The other day we had short drive, and my husband switched with me and parked in garage, without thinking I jumped out and had the key fob out of the car. Not sure if he turned it off correctly. Next day, all lights on dash, could not move out of park. I consulted manual, and tried longer time with brake and Starter button. It started fine and I took out of garage, then back in and parked. I think I should have kept it on to charge things, but I was convinced it was not my 12 V. The lights and interior lights were fine. DH tried to jump with our van next to it—which he has done a few times in last 7 years. Now all is dead, no lights or anything except check engine light. I don’t have a code checker or volt meter. Do I have any options other than tow to dealer? Is my hybrid dead along with regular 12 v? Can we go to PEP boys and buy a battery and install ourselves? Please help! We have disabled family member, need the car!
