NHTSA Complaint #11513516 — 2022 HONDA ACCORD

About three weeks into car ownership while drivng on the highway during the day, I changed lanes and the brakes engaged suddenly for about 2 seconds. No one was behind me or in front of me. No cars or obstacles. I took it into the dealership the next day. They tested it and found nothing wrong. About a month later it happended again while driving on the highway with no cars or obsticals in front me. changing lanes and the car braked for a period of 1 second. It happened again about 10 minutes later but this time braked for 2 seconds and if someone was behind me, it may have casued an accident. Then a week later on the highway, it happened a third time taking an offramp. I took it to the dealership that day and they kept it overnight and found nothing wrong the next day. I am escalting it to the dealership management.
