I have a 2010 EX 35 but I think someone will know the answer to my question. Car has only 44k miles. Replaced battery Jan 2016 since it was 6 years old. Car has run fine. Used it on Thursday for a few short trips, then parked downtown. When I came back to the car 2 hours later, door would not open with the remote, so I used the key inside of the fob, and inserted the fob in the dash, thinking fob battery was dead. Got almost nothing when I attempted to start the car - not even a click, dome lights were dim. Got a jump and went back to place where I bought the battery. Car had been running for about 45 minutes, and the battery checked out fine, car restarted several times.
I left the car there overnight and it started fine. I’ve dealt with this shop for over 20 years, and they’re good. He said the battery and charging system checked out fine. I thought maybe I had hit the on or acc on the start button before I parked it but - I tried locking the car with the switch in the on or acc setting and you can’t lock the car under those conditions. The car was locked when I returned to it and the lights weren’t on.
Any ideas? The car started fine this AM but....what caused the battery to be totally dead?
Thanks
