The entire issue stinks. Had money down on a 2022 until it was put on "hold" because of the recall. Essence of the issue is Ford has two different rear subframes for the Explorer; one with only one rear attachment bolt (into a large cast boss on the cast aluminum differential cover), the other has two rear attachment bolts. There are two large cast threaded bosses on the rear differential cover. The front of the differential is supported by two bolts at its front as well.
Lower HP Explorers, those with the 4 cylinder engines only get the rear subframe with one rear differential attachment bolt. Higher HP Explorers , and police units, are supposed to have the rear subframe designed to use two rear differential attachment bolts.
For some reason, some "person" at Ford decided to use the rear subframe with only one rear differential attachment bolt on all Explorers. Not surprisingly, there have been a number of instances where the single rear differential attachment has sheared on higher HP Explorers, hence the recall.
Now Ford, to address this, is only replacing the rear subframes on the police units. On all the others, they are developing a "retune" or re-flash to do two things: engage the electronic parking brake whenever the vehicle in placed into park, and to "de-tune" the engine somewhat, to reduce the available HP and torque, the details of which are a mystery.
Based on the above, I waved off getting an Explorer.
