Brake Grinding Noise problems of the 2016 Toyota Corolla

Continuing problem when foot is on brake pedal and hit a bump in road, grinding noise and vibration sensation in pedal. Toyota dealer says brakes are ok. Today this happened but this time the grinding noise was pronounced and the car would not brake - fortunately I was not driving at a high rate of speed and barely stopped in time before almost rear ending car in front of me. I have found several complaints on line of the same problem.

Brakes began making grinding noise when applied in during stop and go traffic. Was taken to dealership where I was told brakes are fine. As soon as I left I began hearing noise again while applying brakes and called them back but was told nothing could be done since no issue.

Takata recall, I was driving home in stop in go traffic on freeway and the truck in front of me speed up. Once I accelerated to about 20-25 miles an hour the truck stopped, I saw it and tried to stop but brakes would not work. There was a grinding noise that you could feel and hear as well as wouldn't let you push all the way down on brakes. This resulted in me hitting the person in front of me. Hood is pushed up and front bumper completely off as well as light damage and more but no airbags were deployed. All 3 of my children were in the car with me and this is a hug safety issue.

Several times, I have experienced "brake failure" along with a grinding noise. Braking system must be the problem. However, the dealership says everything is working properly. I have taken it to the dealership 2 times since I purchased the new car. The first incident was in October 2016 - with only 1784 miles. On may 1, 2017; I applied my brakes upon approaching a "stop sign". Unfortunately, the pedal went to the floor( I could feel the grinding in the brake pedal)and there was a delay in my car coming to a complete stop. I took the car to the dealership, again. According to the service department, there is nothing wrong with the braking system. I do not have any warning when the brakes fail to work. It doesn't seem to matter if I am traveling at a slow or higher rate of speed. Please investigate this problem. I am very concerned and the Toyota company doesn't seem to be concerned about this issue.

Breaks dont stop the car and also make a grinding noise when trying to break while going over any kind of bumps.

Brakes make a grinding noise as soon as bought car, took for 1st oil change and told them, also drives like floating or weaving down highway also told about at dealership. Now the heater and air is not right all the time.
