Hello HUMMER community. I currently have a 09 HUMMER H2 SUT. About a week ago, while taking a 90-mile mini road trip to watch one of my fellow Soldiers get promoted to the rank of 1stSgt., I noticed the battery gauge was fluctuating from low to normal readings. On the low end, the reading would be around 10.5 volts, then return to normal. This incident would occur at least 3 times while I was driving. On the way back to my home, the battery gauge would read normal until I got within 10 miles of my home. I had this issue occur when I used to own a 05 SUT as well. Has anybody else experienced this issue? If so, did anybody find the root cause of the problem?
