I go out this morning (car had sat a few days) and try to start the cobalt and nothing.
battery is stone cold dead. i know for a fact i didn't leave any lights on, door cracked open
etc. i hooked up a small battery charger to it, and it started freaking out. lights flashing,
horn beeping. the only way i could get it to stop was to hit the panic button on the key fob.
has this happened to anyone else? looks like a dealership appt. in my near future. -skip.

just for the extra info it's a 2009 ss sedan with 5200 miles.

 

well... it doesnt matter if you leave lights on... all chevys are equipped with a sensor that turns off lights after ten minutes if door is left open or light is left on...

thats really wierd

 

Everything is freaking out because of the low battery voltage. When you apply voltage back to the battery every module is going to fight for that power so they will just click on and off. With the horn going off that is because the security system reset and thinks you are trying to break into the vehicle. As far as what caused it not too sure, it could just be a bad battery this does happen all the time.

 

Been having alot of problems with the enclave traverse platforms, and aveos with the same issue you stated. Havent seen anything with cobalts yet.

 

just a bad battery. plus with the weather change it can drain a battery quicker then u think

 

I had a bad battery last winter. Dealer replaced it.

 

As I read in another thread a while ago,it's probably your ONSTAR.Some have pulled the fuse for it and the battery issues go away.

 

Now I know you probably already checked... but did you make sure it's plugged in?

 

well i charged the battery enough to get it running. drove it to the dealer. they checked
the battery, charging system, etc. they said everything was fine. service manager told
me if you leave it set for 5-7 days without driving it, it probably won't start. several new
gm cars are doing this, gm knows about it, but of course is doing nothing about it. he told
me a new battery will not fix the problem. i told him next time his tow truck will be picking
up my car. lemon law anyone?? leaving a brand new car sit for 5 days and then it not
starting is completely unacceptable. WTF???

 

let mine sit for 5 months last winter with 5000 miles and she fired right up

 

yeah thats pretty lame. i left myc ar sitting for 2-3 weeks and it fired up just fine when i started it

 

My car has been sitting for the past month. Started it yesterday no problem.

 

I don't care what that idiot told you, the battery has a dead cell. It's almost impossible to test for. Replace ur battery and you're golden.

 

i agree with you. they say nothing is wrong. how do i get them to replace it?
it sucks going out every morning and wondering "is my car going to start today?"

 

your battery probubly has a bad cell in it. We have these problems all the time. Take it to your dealer and have them put a new battery in it under warrenty.

 

Try a different dealer if the one you went to first keeps being dicks about it

 

this is what you do

1) report car stolen
2) put car in the drink
3) collect insurance moneys
4) buy different car

 

you forgot step five.

5) Go to jail LOL.

 

You will just have to buy a battery with your own money. I know it sucks, but what would you rather have: a car that doesn't start, or a car that does?

 

No, you take it to the ******* dealer and have them fix the damn thing. you don't be submissive and waste your hard earned money to make up for GM's lack of customer care. it's a warranty, use it, insist on it.

 

and
6) butt rape skip while in jail

 

my grandfathers HHR had some sort of wiring short that drained the battery, they had 3 different batteries on the bitch, and it sucked because the battery was in the back, and the liftgate is electronic

 

7) play drop the soap with the black guy with the big orange afro
