new 2007 Tahoe LTZ
Had it in the garage off, ut the key in and turned so the electronics (radio, gps) would work.
After abotu 20 minutes, I tried to start it and it did not start. I saw there was a message stating service battery - charging battery. Never started that night. The next am it did start.
1st, that seems like not a lot of battery to power things for only 20 minutes. 2nd - where is it charging the battery from?
Also, I see there seems to be a place for a 2nd battery in the front - right side. Is this an option I can add and is it recommened?
Finally - as a note - the Tahoe is just about always makign some kind of noise even when powered off. Any ideas?
