Over a month, still at the dealer; got the leak fixed and discovered another up top (didn't elaborate). Then they called me and asked if my service four wheel drive light had ever been on, which it hadn't...fixed that too. Called again and asked if my batteries were dying, which they did back in November. I replaced them and haven't had an issue since. They're no claiming there's a parasitic draw that's causing the batteries to die and blamed it on a short in my plow controls. How would a short cause a parasitic draw, wouldn't a short blow the fuse? I'm thinking about reaching out to GM and requesting an extended warranty, seems like way too many problems for a '15 that I purchased new with 50k miles. My '02 was bullet proof with the exception of the injectors.
