Consumer Description

My 10 speed transmission on my 2020 Yukon XL Denali experienced a total failure. The vehicle will not move under its own power. General Motors has ZERO information on when a replacement Transmission will be available. Some info online shows it could be months. I am told that one dealership out of Eden Prairie, MN has over 40 on back order and some since August 2025. They claim the issue stems from a valve body. Their communication has been terrible and no one within GM that I have spoken to has any information on what is being done. This is completely unacceptable and I believe it is part of a larger issue. They are making it seem like it’s not important and that needs to change.
