Brake Drum Wheel Cylinder problems of the 2017 Ford Expedition

Recently my wife was driving our grandchildren to school. She put here foot on the brake petal and it went to the floor. She got an alarm on her dash about low brake fluid and loss of brakes. She was able to get he car stopped. We had the vehicle towed to our Ford dealer. They replaced the master brake cylinder and the booster assembly. We now see that there is a recall for 2017 Ford Expedition for exactly this problem. The recall is NHTSA recall number 20v-332. The Ford dealer is telling us this recall is not for our car when we experienced this exact same problem as outlined in this recall.

The brake system went out while driving my 2017 Ford Expedition. The warning light came on indicating low brake fluid. I called Ford about the issue to which they told the issue was not covered under the warranty. After some research there is a recall on the master brake cylinder and brake booster system on the f150 ecoboost. Nhtsa campaign number: 20v-332. Ford's reference number for this recall is 20s31. The my Expedition has they same issue . The f150 and Expedition are the same under the hood. The vehicle is safety hazard due to this issue.
