Air Bag On-off Switch problems of the 2019 Toyota Camry

The first problem: the car has acceleration delays, it bucks and lags when switching lanes and driving in heavy traffic. The car jerks when accelerating at slow speeds. I almost got into a serious accident due to the acceleration delays when making a left in heavy traffic. The second problem is, I received a vehicle alert message on may 30th at 10:30am regarding the srs airbag system. "a malfunction in the srs airbag system has been detected. Contact your Toyota dealer to have your vehicle inspected. " the airbag check light never lighted so I didn't see this message until a month in a half later. Dangerous for my passenger which is usually my oldest son. The car is in the dealership now and they are trying to figure out the airbag issue. I feel unsafe in my car due to acceleration delays. The VIN# is not in the recall list and I do not understand why not. It has the same issues as the other cars being recalled. The third problem: very randomly the seat belt alert alarm will start beeping while I'm driving my smallest son. Both of us have our seat belts and I do not own a big heavy bag. The car wont stop until I pull over, park, turn it off and on. This is not normal but it happens very randomly.
