The display will show a wrench icon and check engine light. The transmission will suddenly downshift and lose power. The RPMs will either rise or remain the same but unable to accelerate. The wheels will intermittently lock up. This occurs at high speeds on the highway and on back roads at slower speeds. Stopping the tuck, shutting it off and turning it back on will "reset" and it will run ok but the timing between incidents is intermittent. There is a recall for this issue however the dealership (Greico Ford in Raynham) refuses to make the repairs, instead telling me this is no longer covered by recall: Transmission molded leadframe extended coverage [XXX] Today was the latest event, however this has been ongoing since December 2024.
