NHTSA Complaint #11321463 — 2015 RAM PROMASTER CITY

I PURCHASED VEHICLE USED ON 2/14/2018. CARFAX STATED NO OUTSTANDING RECALLS. AFTER ABOUT ONE YEAR, VERY OCCASIONALLY, WHEN SHIFTING FROM PARK TO DRIVE, THE GEAR WOULD NOT ENGAGE UNTIL THE PROCESS WAS REPEATED. JUST RECENTLY, WHILE HIGHWAY DRIVING, BOTH "SERVICE ENGINE" AND "TRANSMISSION" WARNING LIGHTS APPEARED ON THE DASH. THIS WAS FOLLOWED BY A NEAR TOTAL LOSS OF POWER AND AN OCCASIONAL STALL. THIS OBVIOUSLY CREATED A DANGEROUS SAFETY HAZARD FOR ME AND THE OTHER DRIVERS IN MY AREA. I TOOK THE VEHICLE TO THE LOCAL RAM DEALERSHIP (PEACOCK - BLUFFTON, SC) AND (AFTER 5 DAYS) WAS TOLD I NEEDED A NEW "TRANSAXLE RANGE SENSOR WIRING HARNESS" ($700. +/-) AND A POWERTRAIN SOFTWARE UPDATE (WARRANTY). SOME RESEARCH REVEALED A RECALL BY FIAT-CHRYSLER (8/2016) FOR THE WIRING HARNESS - S55 / NHTSA 16V-529. ACCORDING TO THE DEALER, FIAT-CHRYSLER WILL ONLY HONOR THIS RECALL FOR A PERIOD OF 2 YEARS FROM DATE OF ISSUE. FURTHER RESEARCH REVEALED THAT NHTSA REQUIRES RECALLS BE HONORED FOR A "REASONABLE" AMOUNT OF TIME, SUGGESTING THAT 10 YEARS IS "REASONABLE". THIS IS DAY #8 AS THE VEHICLE REMAINS IN A BAY AT THE DEALERSHIP. I AM LOOKING FROM SOME GUIDANCE ON HOW TO PROCEED.
