2021 Ford Safety Recall 20S73 / NHTSA 20V795

[TexasJeff]

Just notified of a safety defect in the 2021 E-350 Econoline.

Description: "On your vehicle, it may be possible that the engine cover insulation does not fully extend to the perimeter of the factory engine cover. In addition, vehicles built on a Ford chassis may have higher engine compartment temperatures during certain idle conditions."

My concern is that the dealerships are authorized not only to inspect and fix the factory engine cover and install thermal insulation patches if necessary, but specifically, they're authorized to reprogram the Powertrain Control Module.

What the notice doesn't state is what the reprograming of the PCM will accomplish, or mentions anything about the PCM outside of the fact that the dealerships will reprogram them. Does anyone here have experience with the PCM and its function and are able to speculate and comment on what they're doing with it, why the programming is faulty, as well as any possible side or after-effects?

It could be to turn the engine fan on earlier but that’s pure speculation. I’d call the dealer and ask. They should be able to find out.
