1st when the truck is running it has 14.7v from cigarette lighter, and I had an app that reported over voltage since day one and have to replace the battery every 6-8 months. 2nd less than 60,000 miles had issues with drive train (could be something else as I’m not mechanical) and it went after the 60,000 miles because they said it was a computer issue. They said the issues were unrelated even though they did the same things. I had to wait over 2 months on parts as it was the same issue that GM had as they had the same parts.
