New 2020 Silverado 2500 with power tailgate. On vacation and went to open and it’s not working. Yes there is a tonneau cover but it’s been on for months and never had a problem before. Got the cover open and tailgate still not working. Doesn’t work with remote, button on the tailgate or button inside truck. When I push button inside cab it says “tailgate release unavailable.”
Anyone have a similar issue and hopefully a solution?
