    Chrysler (FCA US LLC) is recalling certain 2019-2020 Ram 3500, 4500 and 5500 cab chassis built with a Cummins 6.7L High Output engine.

    I am attempting to get recall 21V-880 done. This is a safety recall where failure of the engine could result in a crash. I contacted my local dealer and they state repair parts are only available in limited quantities. They put me on a waiting list and stated there are 105 vehicles ahead of me and they don’t think they will have the parts to repair the safety recall until late 2023. This is completely unacceptable for a major safety recall.
