Consumer Description

I have a 2021 Tahoe that while circling a parking lot at my son's football practice. The Tahoe's emergency came on and the Tahoe abruptly stopped. A checked engine light came on. The Tahoe wouldn't release the emergency brakes. I was finally able to get it released. I took the vehicle to a transmission shop because I plugged OBD scan tool on it. It had two transmission codes. One generic and one for the vavle body. The transmission shop said they have had lots of Tahoes with the vavle body's going out. They told me about N242454441. I called Chevrolet and they advised me that wasn't for my Tahoe. I asked why and they said they don't know. If this is effecting the desiel only models then why is mine doing the same thing. Parts cant be ordered either. Please look into this matter.
