Twice in the past week I've had to jump start my yukon. I drive it every day. The battery is from 09/2018, so not old enough to be time to replace. I noticed that the voltage meter in the dash is running higher than normal. It's typically right at 14V (13.8V per the scanner, which agrees with my DMM) which is normal for every GM vehicle I've had. According to my scanner, voltage is fluctuating between 14.9V and 15.3V. Not normal.
What might be the issue? Bad battery overworking the alternator? Or bad alternator overcharging the battery?


P.s. what happened to the automotive subform? I thought we relaxed the automotive topics ban and created an automotive subform. Am I gaslighting myself?
