I have had my 2014 Enclave to the dealer and they say normal. Drove it yesterday 126 mi and today after a 15 mi drive when I stopped and sat for 2 minutes with the radio on. I am sick of the Low battery voltage message went on again. Bunch of crap my 2011 Enclave never did this. Dealer says they wont do anything but wait until it quits and leaves me stranded. I buy Premium vehicles from GM to get this.
