NHTSA Complaint #11719550 — 2025 HONDA HR-V

While driving on highway under 40mph, the brakes and steering wheel locked simultaneously. I was unable to control the car—pressing the foot brake and emergency brake did not stop the car and I could not steer as the wheel was locked. I ended up on the side of the road alongside a wall of snow. The dashboard was lighting up throughout this time with rotating emergency messaging—TPMS, transmission, brake system, flat tire, etc. There were no warning messages displayed and complete control of the car was taken away without warning. It was 530am so I was lucky there was no one else on the road or else this could have led to a fatal accident. The car was towed to the dealer and they said it was an electronic brake booster that went bad, but are unsure if this caused both the brake and steering failure. The dealer has not been transparent or helpful. They initially said there was nothing wrong with the car and that it was safe to drive. I reported it to Honda corporate and they have not gotten back—triaged as level 1 incident due to severity.
