Follow-up on my dear poor Ram Ecodiesel. After posting a negative Google review, emails to Lithia and FCA, and postings on this forum, there was a "rush" job to fix my truck. Four hours later, they contacted me that the vehicle was ready. I don't know what spurred them on but the final piece to the puzzle was to disconnect some sensors, try a start, and reconnect the sensors, more or less a computer reboot. With 300 miles of experience, mileage and performance are the same as old, feeling vastly superior to any of the rental or loaner vehicles. Smog check shows all but two tests have completed successful, remaining ones are pending.
Lessons learned: Ram Care, Lithia Cares are misnomers. Negative feedback and personal visits to the dealership seem to matter more. Neither the dealership nor FCA compensate for five months of lost use and depreciation. I still don't know how the new HPFP is improved over the notorious Bosch CP4.2 pump. I am packing a Garmin InReach and upgrading AAA service as the next failure could put us in a really bad situation. Keep posting you all.
