The brake vacuum pump has gone out four times now. While driving the brakes suddenly become hard as a rock to push. Of the four times two of them have been close calls to having a serious collision. This is a known issue with these vehicles so it blows my mind there isn't a recall for this.

While traveling out of town on the highway,we had a sudden loss of power. My vehicle wouldn’t accelerate or shift. My check engine light came on and a message displayed that said something about reduced power. After limping to a dealership while in another city, I managed to wait hours for my husband to pick me and my children up. We waited several days for the dealership to tell us it was the valve body that needed replaced. My vehicle was NOT in the original recall for the valve body,…

I purchased the truck at the end of March 2025. Within a few weeks I was noticing different issues in the transmission. It would occasionally shudder, have jerky or long shifts, would jump gears and lose power. The shudder was random but mostly on the highway, the jerky or long shifts would mostly occur when the egjne was cold and more often in cold weather. The lose of power and jumping gears would occur when towing and when I was in the mountains, once losing power as I was turning onto a…
