Brake Sensor problems of the 2018 Honda Accord Hybrid

I purchased a new 2018 Honda Accord Hybrid on June 30, 2018 from Honda of kirkland for my daughter. On Monday, February 25, 2019, when she was driving back from class on a road at 35 mph, the collision mitigation system brake warning flashed then braked immediately, stopping the car in traffic. No obstacles or cars were in front of her. Fortunately, the cars behind her were far enough away that they were able to stop. In addition, she tried to get out of the way of traffic by pressing the accelerator, but the car would not respond for several moments after the automatic braking occurred. She also told me that the brake warning had been coming on often when nothing was in front of her. In addition, the lane departure feature has been malfunctioning, trying to pull her to the left lane into oncoming traffic when driving on curving roads. The car is currently at the Honda dealership, but the only thing they found was "a little dirt" on one of the sensors, stating that there was nothing wrong with the Honda sensing system. I have found class action lawsuits filed against Honda for faulty collision mitigation systems on at least two of their models (accord & crv). In addition, I have found pages of results for these problems with Honda and Acura (Honda corporation) when simply typing in "collision mitigation system problems". Please see the links below.
