I was driving my 2019 Honda CRV yesterday and it slammed on the brakes to a complete stop all by itself. It shocked me and jerked my head so badly. If I wasn't wearing my seat belt I would have gone through the windshield. If someone was driving behind me, they would have hit me. Please advise on what I should do. There is not a recall but online I saw there were other occurrences like this. This is the first time this has happened since I bought the car new. I have not taken it to the dealer yet. The brake warning light came on as it was braking.
