Brake Sensor problems of the 2016 Mazda CX9

This incident happened on 31st July, when my wife was driving this car on highway 4 martinez, CA at around 5. 00 pm with our daughter (2 years old) returning from daycare. She was driving at approx 60 mile/hr, when the car started giving audio visual warnings on multiple failures and the car started slowing down without responding to the gas pedal and engine propulsion reduced to 'zero'. My wife panicked and was luckily able to pull over on the curb side safely, even though traffic was very high. She stopped the car and turned off the engine and waited for 10 mins and restarted the car multiple times and made sure that no more warnings are displayed, before driving again, however the 'engine warning light' stayed on. After a while she drove home almost 40 miles away very carefully without using any cruise control. Here are the warnings, that came on during this failure, pictures attached. Engine malfunction light. Tire pressure indicator. Stability control indicator. Temperature indictor cruise control failure warning message �front radar sensor system malfunction� warning message �forward Smart city break malfunction� after a day we dropped the car to Mazda dealership for inspection and they found multiple failure codes and they did necessary repair (inspection and repair invoice attached). Even before this incident , we reported multiple times to dealership that the car central information system abruptly shuts down during drive. But they always said that there was no problem. This incident on a freeway was very serious, my family or other drivers could have been in a injury accident because of this issue with Mazda.

When driving at 35-50 mph, my 2016 Mazda cx-9 periodically brakes suddenly while driving to a scrubbing forceful stop tossing things off the back seat, placing me in danger of a rear-end collision. Sometimes a very quick beeping sound is made, "b-r-a-k-e" appears on the panel in large letters --- then the car automatically comes to a sudden stop or it occurs with no notice. I have taken it to the dealer 3 or 4 times only to be told that they could find nothing wrong. No objects of vehicles were immediately in front of me and the sensor was clean when this has occurred. This sudden stopping has occurred on the freeway, in rush hour traffic and on city streets. This has occurred at least 6 times since purchased 03/17/17. I am fearful that this problem will result in injury or death to me and others.
