That seems like an easy install and a quick fix... any know issues with warranty? Is it something to remove before going in for warranty work or servicing? If the tech plugs into the truck can they detect that something is not right with the auto start stop function?
I have a ‘20 at4 with 1000 miles CEL just came on...??? Anyone ever get any solid response from GM? I plan on stopping by the dealer and seeing what they say tomorrow.
