Car won't start
I have a Pontiac 2007 g6, new battery 2
months ago car won't start no power to tie
lights on at all
Sometimes the battery terminals will get corroded....usually the positive (red colored one). Have you checked that?
it could be as stated above or your alternator (device that charges the battery while driving) could be going bad. You can get both checked at your local auto zone for free. If it is neither of those, then that usually means some type of bad connection. Especially if you haven't had a problem before... hope you get it solved :)
