There is a recall on the catalytic converters of my year Expedition, but my check engine light came on at 86,000 miles, outside the 80,000 limit Ford put on the recall for the part. I think Ford should stand behind their product and the parts they are using, since the catalytic converters have failed on my car, my husbands expedition, and my dad’s ford 150.

The service engine light has come on and off (and stayed on, in some instances) for a few years. The alert in the Ford app states that there is a problem with my vehicle's emissions and exhaust system. I have taken it to my local Ford dealership many, many times. When the vehicle is "throwing codes", as they call it, it has to do with the cam phasers. I have had the recall on the cam phasers done already, but they refuse to fix it again under the recall because "the part numbers have changed". Same cam phaser issue, but the same exact parts have different part numbers than they did 2 years ago, so now Ford doesn't have to fix it? The problem has been ongoing since 2020.

I was on a road trip of about 900 miles. My vehicle at the time had 103,000 miles. All maintenance service intervals had been complied with since I purchased vehicle new. About half way through the trip the transmission started acting up. I was on the highway between 75 and 80 mph when it suddenly downshifted in a jerk then it failed to accelerate. This whole time I was pressing the gas pedal and my speed continued to drop and the vehicle jerking forward and back. I was able to put it in “manual” selectable speed and regain control. I had the vehicle inspected at my destination and the dealer could find no fault codes and fluid check was good. My vehicle continued random jerky shift changes at the most dangerous times. I still got no check engine light or any such failure or service alerts. On my return trip home, it did it again. This time I was watching all the gauges. I noticed my engine coolant temp spike to 240 degrees and my transmission fluid temp spiked at 247degrees. Outside air temp was 40 degrees and it was three occupants and no towing involved. The dangerous jerking and random transmission shift changes continued. After about 30 minutes of reduced speed driving on the highway the temps dropped. However the shifting was hard and erratic. I took the vehicle to the dealer after returning home. I now need a whole new transmission. This situation was extremely dangerous as to the uncontrollability of the slam shifting of the gears causing a rapid change of speed. I am very fortunate I was not in a wreck! In my research of this problem, I found I was not alone. It is a terrible design by Ford. It gives no warnings other than slamming you around in the vehicle. Something must be done!
