2018 Quicksilver Metallic Jet Black Leather SLT-1 Tow Package
So I am back at the dealer as they continue to hunt for the shift flare issue that seems to be getting worse. Today my service advisor calls and say the manual shift button doesn’t work. After telling him I had never used it before I asked how they figured this out. He said it was picked up from a stored transmission code. He then tells me that this might not be covered under my power train warranty and he wanted the info for my aftermarket warranty. I assumed GMC would cover it under their warranty....... thoughts from you guys? Thanks in advance.
