No i dont think it is my battery, after my car sits for a bit it will start again i have been reading up on it and my gas is low and im over due for an oil change so im thinking water got in my gas tank from all the cold weatheri mean -37 weather i think where the gas is so low its freezing.. and the fact that i am over due for an oil change has a big part in it as well But im still completely confused with my wipers that keep breaking and my door lock i cant lock it from the drivers door i can unlock it from that door but i can only lock it from passenger door... i love my G6 its the best decision i have made buying it but i just dont understand how so many things can be going wrong with it

For one....its an 08! take that sucker to the dealership and get answers to your questions and issues!

I was having starting issues as well. And since playing around and asking questions have gained alot more knowledge about the battery and what not.

To me it sounds DEFF like your battery will be the origional it came with, and is likely weak and maybe even partially frozen.

If you start your car, your starter draws like 200 amps and only leaving it on and driving it for 5 min, may not be enough for the alternator to perk it back up.

Have you been getting your car boosted?

I suggest taking your car to a friend or family and put it in a garage, let it thaw ( battery ) and test it with a multimeter. a solid 12v battery should actually push slightly over 14, my stock battery for example was COLD, partially frozen, when tested it was only putting out 6-7v. after it thawed and left a trickle charger on for a week...its like new now, putting out over 14v. Needless to say i have a new one in my car and the old one for a backup now.

My gfs VW golf had the same issue...we left a trickle charger on the car, under the hood for a week and its just fine now as well.

If its TOO COLD, and your car is simply too cold to start...every time you try to start it it draws more and more power from the battery. say for instance you try and start it intermittently 5+ times throughout the day or what ever...tomorrow could be much warmer, and it would start on a fully working battery...but yours is now drained.

I intend to get a battery blanket / heating blanket for it if not this winter, next.

Do you plug your car in? another thing is that cord may be dammaged due to people backing out with it plugged in. ( also the case with my gfs car ). it had no visible damage, but we hooked a multimeter to it and nada, held it the right way, then had a circuit. the rubber housing was ok, but the wire on the inside was pulled apart and also starting to corrode. we put a new end on just fine, after that and the trickle perk up for a week on the battery it has yet to not start ( assuming she plugs it in ).

oh, and yes we have had to already change that end AGAIN within the month she busted the new one right up lol

I was having similar problems starting my car in the cold (down to the single digits), and my key fob wouldn't lock/unlock my car intermittently. My wiper blades always seemed to work though. It ended up being my battery. I have an 07 g6 and it still had the stock battery, which apparently isn't a very strong battery to begin with. Even the cheapest battery at my local auto parts store had a higher output than our stock one. After putting in the new battery my locks work just fine and I have never had a problem since.

i would check the battery first, if not the cause they sell a water remover that you can buy at auto zone to put in your tank on fill up.
