Two day ago I had a low battery message and could not use heated seats etc. for about three miles then all is well. I started the car this morning, it was 10 degrees out and the car had sat for 24 hours, everything normal. Took it to Pep Boys for a new battery and they said they did not think it needed a new battery or it would have been hard to start...told me to come back when the message was on the display.

Drove home all is well, three hours later, start the car and there is the message again, dirve to PepBoys but the message was gone by the time I got there.

What do you think?
