Two things happened in the last couple days. First, the wife took the Traverse out to go shopping. When returning, she inserted the key in the ignition and it would not turn. She says she took the key out and reinserted it 20 times before it would turn, anyone else have this happen? And second, we went out for dinner tonight and the drive was about 30mins. I looked at the gauges and noticed that the volts gauge was down from normal. The volt gauge usually reads steady at the 14 mark, but today it dropped the line below 14. On the way home it was back at 14 and held like it always does, why would it change?
