I have a Chevy 2011tahoe.i have to replace the battery at least once a year. It's acting like something is grounding out. If I use it at least omen time a day each day of the week it will start up the next day but if I don't use it a day it won't start the following day. Has anyone else had this problem.
Have you had the Alternator load tested to see if its putting out the correct amount of voltage, that would be my starting point. If that works out to be ok. Allot of times an interior light or door switches seems to be the problem. You can remove the light blubs to see if there is any difference..
Have a parasitic draw test performed. There is always something pulling power from the battery. Such as the computer, radio, etc. But it sounds like there's an excessive draw going on. Do you have an aftermarket stereo installed? That could be the culprit. HTH. -Jim
