So same thing happened to me. Got ready to winterize the car and started driving the beater. Went to start it this weekend to keep things happy and nada.

Wouldn't turn over in the least. I'll run through the various options posted earlier in this thread, but otherwise is it going to harm the car to *sit* dead for 4 months? Car isn't insured for driving now until March, so I can't really bring it to a dealership.

 

I have mine garaged for the winter. Went to start it yesterday after 3 weeks and DEAD. Tried charging it and nothing. The charger keeps giving an error and saying internal cell leak, replace battery. The thing is only 6 months old

Have the dealer replace the weak OEM battery (dead in your case apparently) with one of the recommended more-capable battery. If you want to avoid the hassle of getting the car to the dealer, pick up an Interstate MTP-35 (that's one of the recommended replacements) and install it yourself.

BTW, you might want to try another charger if you have access to one. Could be a bum charger.
