No incident as of yet. The wide angle driver mirror cannot be set high enough to see down the side of the truck. It is a factory installed towing mirror. I have to lower my my seat all of the way and I cannot see the top rail of the bed. The mirror won't let me see down the side of the truck which makes it really dangerous when I pull my 32' fifth wheel trailer. I took it to the dealer and they told me at first ( I purchased the truck on 01-22-2023) the mirror is one of 6 items that warranty doesn't cover. Then they told me it is very difficult to get the manufacturer to authorize replacement. The dealer eye balled a mirror just from standing in front of it on a lot truck and said he couldn't see a difference. All I can see out of it is basically is the rear tire. I called GM and the person looking into it was transferred after about a week. The person that took over asked me to give him a week to look into it. He called me today and said he hasn't had a chance yet that he needs a couple of more days.
