FCA in November 2019 issued a second recall for 2011-2014 vehicles, but has still not devised a fix and all dealers will turn away customers seeking a fix because there is no direction from FCA and no parts made specifically for this issue.
I have a 2012 Grand Cherokee that is both listed by VIN for this recall and is exhibiting the issues associated with it. Without direction from dealers and FCA, I don't know what to do in the meantime.
To understand the issue, a legal firm summarizes it well. In general, there is a non-removable power relay that manages the fuel pump. This part has been deemed a safety issue and it's recalled under recall ID v62. When faulting, the vehicle will not start and/or cause a stall while driving. I'm experiencing mostly a "no start" issue, though with the coming summer heat, I'm also experiencing stalls when it does start.
