I have 53k miles on my 2018 and last weekend on my way from Jersey to WV the water pump blew up at Hagerstown, MD. Ruined my trip BUT GM did right be me. Happened on Friday evening. GM towed to the Hagerstown dealership. I had a place to stay as my in laws live 10 minutes from where I broke down. On Saturday morning, GM offered to put me up or get me a loaner to finish my trip. Got the part ordered Saturday, delivered/installed Monday and got me headed home. Warranty covered. For a bad situation, it turned out as good as it could have.
I don't have pics of the water pump but when I say it blew up, it was in pieces.
