Slight braking vibration. Normal?

I have a slight vibration that is felt through the entire car when braking downhill at highway speeds. The vibration doesn't affect the steering wheel and doesn't necessarily feel like it's coming through the braking pedal but rather feels like the whole car is 'slightly' vibrating with a rumbling(ish) sound.

I took my car to the dealership and they said nothing was wrong although I have reason to believe they didn't actually do much investigation. They said they took it for a test drive around the local area but after reviewing the dashcam footage (that I'm guessing they didn't notice I have installed) they simply went down the road, braked slightly fast, and the turned around and went back to the dealership.

I took mine to the dealer which said they couldn't replicate a similar vibration due to excessive speeds. (75 coming off highway, braking to 45 on ramp). I have excessive shaking, so much so that I actually find myself pumping the brake because I feel like it's going to give out on me. Pumping the brake, on a dry road, for fear that my brakes will give out with only 20k on the car. Something isn't right. I've contacted Subaru of American and will likely have to take the car to another dealer close to the highway that can replicate. I'm seriously concerned for my safety and that of my kids. Thoughts?
