NHTSA Complaint #11546544 — 2022 RAM 2500

My 2022 Ram 2500 with only 9,900 miles failed to start requiring it be towed to the dealership. The dealer reported the fuel injector harness had failed and replaced it but then it started throwing other codes. The technician determined there was metal shavings in high pressure fuel pump (HPFP) so they contacted Ram engineers and started a STAR case. After two months and countless "pictures" taken and sent the the Ram engineers, they claim it was contaminated fuel which caused the metal shavings to be found in the HPFP. The engineers stated that there were no metal shavings found in the return filter so the metal shaving came from "contaminated fuel." This logic is impossible because for metal shavings to make it from the fuel tank to the HPFP and be visible they must travel through two fuel filter, one of which filters down to 5 microns. The dealership acknowledged the engineers logic didn't make sense to them either. The return filter showed some debris but if metal shavings can pass through a 5 micron paper filter than it would also pass through the metal screen found on the return line inside the tank. Ram is refusing to honor their warranty and trying to stick me with the bill even after they already are aware of a faulty fuel pump in their trucks.
