Brake Sensor problems of the 2019 Toyota Tundra

Less than 3000 miles when incident happened. While driving at 55 mph on a highway the dash screen said brake and a chime was heard. It was late evening 3 days ago and their was absolutely no other vehicles around me. My initial reaction was to brake however I did not. It also happened two additional times at about 45 mph on the final few miles from my home. The indicator did not stay on long enough to get a photo of it. When I returned home I filed a case with Toyota USA. I then called them the next day. Today I contacted the dealer about taking it in for the to check. At that time the service rep advised me there is a recall on the part sensor on the anti collision avoidance system. I received an email reply from Toyota USA however the reply did not provide me with any information , other than the case was going to be entered into their database. They will place a foamy tape on the back of the sensor after running a diagnostic on it. This seems a bit under done and a band aid for what could be a safety hazard. If it is a water issue (no rain on the day it happened and didn't happen on the way to my destination) I researched the VIN for the recall and I received "there is no recall associated with my VIN, answer. Hopefully the NHTSA will do a simple website search and see the numbers of people having this issue. I prefer not to have any safety issues while transporting my family in the vehicle.
