I was told by my dealer that because my 2021 Silverado 1500 has Lane Change Alert or Side Blind Zone Alert and the new mirrors do not, that the new mirrors will not work. They said they would install the mirrors but I would be out the money if the truck threw an error code. I can do without the warning lights in the mirrors but can't drive with a constant error code. Anyone install these mirrors with Lane Change Alert or Side Blind Zone Alert and did it work for you?

UKC is the RPO code whatever you call it. Will it not work or throw an error code?

I have a 2021 Silverado 1500 LT with lane change alert (UKC). I want tow mirrors. I found a part 847776100 on the GM part hub web site and the dealer tells me this is for my truck. Only, it is not designed for trucks with lane change alert (UKC). I don't care about lane alert and need a tow mirror. Does anyone know if I add this mirror will it work and lane alert just not work or will the truck throw an error code?

They do not. They were simply reading the text on the GM parts hub web site that says it does not. They do not know if the truck will pop an error code or the lane change alert light will just not show because the tow mirror does not have it. They did say I would need to buy a new wire harness and the BCM software would need to be updated. They did verify the part was listed in their parts DB as a valid replacement part for my truck, just not with lane change alert.

I have a 2021 Silverado 1500 LT with lane assist (UKC). I want tow mirrors. I found a part 847776100 on the GM part hub web site and the dealer tells me this is for my truck. Only, it is not designed for trucks with lane assist (UKC). I don't care about lane assist and need a tow mirror. Does anyone know if I add this mirror will it work and lane assist just not work or will the truck throw an error code?
