In the case of the 2020-2021 Ford Explorer and Lincoln Aviator, that issue is motor mount hardware. Specifically, the fasteners that secure the passenger-side motor mount may back out. In Ford's words, this can result in a "loss of power," which is the entirely predictable result of an engine parting ways with the vehicle it powers.
As alarming as that may sound, owners should not have to worry about anything extreme, as the passenger side mount is only one of multiple, and Ford says it is not aware of any incidents that have occurred with vehicles in customer hands. Ford says it impacts only about 1400 examples of the Explorer and Aviator in the States (plus two in Mexico and 65 in Canada) that were built at Chicago Assembly Plant between July 28 and 30, 2020.
Ford is in the process of alerting its owners to the recall, and those with affected models will have their mount hardware replaced by their local Ford dealerships free of charge.
The 2021 E-Series is being recalled for a potential heat management issue resulting from improperly aligned thermal insulation on the underside of its engine cover. In vehicles where this insulation was not properly installed so that it reaches all the way to the edges of the cover, the resulting heat bleed can cause high in-cabin surface temperatures, and direct contact them could result in burns.
This is the larger of the two recalls, as Ford says it covers nearly 33,000 examples sold in the United States and Canada. Fortunately, as with the above issue, Ford says it has not been made aware of any customer incidents. Ford says the remedy is a set of insulation patches for the exposed areas.
