Consumer Description

My rear wheels randomly lock up and truck violently shakes. It does it randomly in very long trips so GM and every dealer I've brought it to just says that "they cant help me because they cant get it to replicate. Had the same issue with my 2020 and it has an open recall for the exact same thing. This is very dangerous and is going to get someone hurt one day if gm isn't help responsible and fixed their valve body failures for ALL of the 10L1000 L5Ps. Not just 2020-2022....it's ALL OF THEM. 2020-2025!!!
