Question about 2006 GMC Acadia
Has anyone ever hear of this? I have a 2008 GMC Acadia - Onstar, GPS, Electric seats, all the goodies. I didn't use the car for 3 days and the battery died. GM roadservice says you need to use the car every 2 days or so or else the battery will die because of all the electrical devices. Can anyone confirm this? Or is this a job for Mythbusters
There is no way Onstar would drain your battery in two days. Electric seats? They only draw power when they are running, same as any other device in your car, except the clock. You have either a ground -fault issue or a dome light is always on. Good luck.

I have been having this problem after 40K miles now. I dont know if its the battery or the fact that GM, in all its infinate wisdom (NOT) decided to use a LAN system for everything in the car. This means that EVERY circuit is ALWAYS powered, whether the car is on or not. This is why, if you try to find a switchable fuse to tap into for a radar detector or Garmin you wil be unsuccessful. Also, this is why the cigarette lighters always on. Im not sure what the actual load is on the system when the car is off due to the LAN being powered, but it could be enough to kill the battery after a couple days if the alternater hasnt been run to charge it up.
i have had a radar detector hooked up for about a year now which is ALWAYS on, even when the car is off and it has finally started to take its toll on the battery, I think. The problem isnt your specific car, its the way they designed ALL of them.

My friend had a similar problem The dealer was unable to fix it. They returned it under the lemon law, and are now completely happy with their new replacement Acadia!

My 2007 Acadia can sit in the driveway for a month and still have plenty of power left in the battery. The Acadia is funny in that it will sometimes act like it doesn't get any power (dead battery), but letting it sit for 5-10 minutes often allows it to start quickly. Cars aren't like the old days when turning the key directly turned the starter...now cars start themselves with the key being more of a formality for turning the starter motor. Push a button briefly and the car will continue to try to start itself, even if the key is no longer being turned.
There is no way your battery should die that quickly unless the battery itself is either worn out or internally shorted and delivering low voltage.
