2018 Ram Dually 6.7L. 47,500 miles in August 2022. I love this truck, but c'mon the forums are covered with this problem. This is a recallable issue, so save all of us the $700 repair that will likely happen every 30,000 to 40,000 miles over and over again. This is a safety issue and non-working ABS on a heavy truck is no joking around. I get the flashing dashboard warnings over and over again...every 4 to 5 seconds with the beeping. It didn't matter if I was parked or top gear on highway. It always knocks out my cruise control. Frustrated this isn't under warranty, total recall or at least a Tech Service Bulletin and let us know the replacement part is a newer and better design or manufacturer. Ram gets a black eye from me on this poorly designed part. I ended up buying the part of Rock Auto for $300 and took the three hours to do it myself. Messy, tight space job, with bleeding the brakes...not for the uninitiated types.
