2005 GMC Yukon V8 All Wheel Drive Automatic 10900 miles
When car heats up, 20 miles or so, the voltage as shown on the gage drops to about 11.8 volts. When you turn on the lights, it will slowly climb to 14.8 volts. Other than that every thing still works, but I assume my battery will give out early.
have the same problem?
