NHTSA Complaint #11544203 — 2019 HONDA CIVIC

I was driving down the highway near where I live in Hanford California the highway is 198. I was going 68, 69 mph. No one was on the road my car literally slammed on its brakes and jerked to the right.this has happened 2times I have turned off the assist I’m to afraid it will happen again. I am bringing it into the dealership tomorrow and also have them check my airbags the light in the dashboard intermittently keeps coming on then after a bit it will turn off. The first time I brought it in for the airbag lights coming on they informed me that it was due to me pulling the seat back to far I am 5 foot four. I don’t normally pull the seat back. It would be more closer to the steering wheel for me, but there was a problem supposedly with the connection that is under the seat it doesn’t make me feel too safe to think that me moving. My seat is going to prevent my airbags from deploying God for bid if I get into an accident.
