NHTSA Complaint #11460836 — 2016 FORD EXPLORER

While driving would shudder when getting to approx. 60-65mph. No check engine light. Dealer stated could not diagnose if no check engine light on. This went on for 1.5 years. I kept taking back but still no light. March 2022 it started running really rough while sitting at a stop light, no power at take off. Took to the dealer who said it was covered , diagnosed it as Torque Converter, and pump waited 4 weeks to get parts after being told twice covered 100% but then found out not covered as when it was there previously they did not do the Customer Satisfaction Program 20N07 where PCM reflash was required. Now Ford corp and dealer say they are not covering this. Why did the dealer not advise of this while there before this program expired.
