Brakes Failed problems of the 2014 Cadillac SRX

The brakes on my Srx fail to operate when you push on them it feels like you have brakes and you feel a pressure on the pedal but the car doesn't stop there's a delayed response and it happens at random I've owned many vehicles in excessive 30 vehicles I have been a car salesman for 10 years and I have never experienced a car like this it has break fade or or ghost breaks I have had an accident because of this and ran into the back of a vehicle but in addition of that I have run into the back of vehicles on four occasions with this vehicle currently I own three vehicles and this is the only vehicle I've ever had an accident in and now I've had four incidents of bumping another vehicle even while parallel parking because the car doesn't stop additionally I had a friend of mine with over 30 yr in the car business drive the car and he has the same problem I've looked online now and I found that many people have this problem this is a serious safety issue I don't understand why this hasn't been fixed and everyone takes it to the dealer and the dealer tells me your brakes are fine there's a problem in their software for the anti-lock brakes and it doesn't apply the brakes when you think they're on their not.
