Bought a 2005 Accord Hybrid for my son. When we test drove the vehicle it started and ran really smooth. Next day went to pick up the vehicle and all was good for most of the evening. After stopping for fuel it started but labored as of the 12V battery was dead. It did start though and ran fine. I went to advanced auto to have the battery tested and they said it was perfect. Again started with some hesitation but still seemed to drive fine. Went to pick my son up from work. Shut it off and then no crank. Plenty of power still because headlights were bright, radio worked dash lights are illuminated. Tried several things to get it going and nothing. Had it towed to our mechanic and the codes in the picture popped. He says probably the hybrid battery but I want to be sure before I pony that much money up. Does anyone have any suggestions or experienced this? TIA!
