My car died when I'd let it sit overnight. So I'd have to jump it every morning. Took it in, the first dealership said it was the battery. I got a new battery. A week later, the same thing. Every morning dead. The ran tests for a week and concluded that there is a draw on my factory radio that drains the battery. Hmmm? so now I'm supposed to put in a new radio to fix the problem. Another $500. I don't want an after market radio, I simply want mine to work. Thoughts? Any junk yards or radios out of crashed Impalas I can use? This just seems sort of odd to me. My solution now, is that I pulled the fuse out of the radio. Starts great every morning... but no radio/cd.

Re: Factory Stereo Drains Battery
I have had this problem with a few of my cars and I thought the same that my battery was gettin drained by the stereo but really my battery was going bad hich resulted in the radio staying on for some odd reason, but i replaced the battery and all is good with no more problems, so I would take my battery down and have it tested.

try checking trunk light I serviced a lot of draining battery problems . I had one the other day the customer states every 4 days need jump start . 1st step ck charging system ok , starter draw was good . started to ck all drains all were normal . after dealing with this issue for a month i replaced his battery with a new one he never came back . calls me for reg service . A week cell in battery can pass the test . Hope this helps .
I have done this before, put about a 10 amp charger on the battery. Pull the courtesy light fuse first. Look at the battery charger, it is probably charging several amps, pull one fuse at a time. When the charging amps drops down you found the fuse the controls the problem. I had a car several years ago that someone pulled the seat belt all the way out, somehow it was pulling a load and draining the battery overnight.
Hi, seems to me it's time for a new battery, probably the original battery in the car and 72 -78 months is a good useful life, however you can pull in to a place like auto zone ( I suggest at a time when they are not that busy, early a.m. ) and they will do a diagnostic check for free and check out the charging system , battery , and any drainage of current when everything is off for you but I'm sure it will be ok or it would not crank all day but the long over nite hours drains what little voltage that is in the battery. A battery that is bad will not fully charge because of a bad cell inside of it. Good luck, hope a battery fixes you up!!
it seems like something is draining your battery while the car sits overnight. causing the battery to get weaker and weaker putting stress on the alternator making it fail prematurely. the dealership will do a paracidic drain test where they'll find out what is draining your battery while your car sits overnight. it could be a bad module somewhere that's staying on when it shouldn't be.
make sure that every thing is turned off pop the hood get out and shut the door raise the hood and unplug the hood light, then disconnect the battery,
if you get an arc, then you have a short, probly the hot wire leading from the battery too the starter laying up against the manifold!!!!!
We had the same issue with our 2007 Yukon Denali XL. Died on us twice after sitting for short periods of time; once we watched a DVD with the engine off and battery died within 10 minutes. The dealership kept it overnight to troubleshoot why the battery died so quickly. They said the radio was "pulling" too much from the battery. (They supposably fixed it) But again a few days later the battery died again after sitting overnight. We brought it back to the dealership and they brought in a GMC "expert" to replace the entire DVD/CD/Navigation system. They also replaced our battery with a much larger battery, similar to the ones that GMC puts in there diesel trucks. They had our Denali for 5 days, but it appears to be fixed now.
Getting it fixed correctly wasn't without headaches, but it was all covered under warranty, including the battery. And they are updating the nav w/ the new edition disc as well for no charge.
