NHTSA Complaint #11631695 — 2023 CHEVROLET EQUINOX

Entering a freeway off-ramp at about 65 mph, I depressed the brakes and the brake pedal went to the floor with little resistance. Two error messages were displayed on the dashboard: "Brake System Failure - 62 MPH Top Speed" and "Service ESC". The following dashboard lights came on: Check Engine, Brake, ESC, ABS. I held the brake pedal to the floor and coasted to a complete stop at the intersection, then proceeded slowly into a nearby parking lot and stopped. Braking effort did not become difficult, rather it was reduced to a small fraction of normal braking power. An online search indicated that disconnecting/reconnecting the negative battery terminal might resolve the problem, and it did, allowing me to carefully drive home with full braking. The local Chevrolet dealer replaced the brake system control module based on GM document 5081450.
