Warnings problems of the 2024 Chevrolet Equinox

On may 9, 2026, while pulling into a parking garage parking space at low speed (below 5 mph), the brake pedal was pressed but failed to engage or slow the vehicle. The pedal was pressed completely to the floor with no resistance, and the vehicle continued moving forward until it struck a wall, causing damage to the vehicle. Earlier the same day, the brakes produced an abnormal hissing sound while pulling out of a parking space. No other symptoms or abnormalities were present prior to failure. The vehicle may also have recently received a software update, although it is unknown whether that is related to the incident. The failure appears to involve the brake system and the driver safety assistance systems equipped on the vehicle like forward collision alert, automatic emergency braking, and dynamic brake support systems. The exact failed component is currently unknown and remains under inspection by a Chevrolet dealership. No warning lights, messages, or audible alerts appeared before, during, or after the incident. The automatic braking/collision avoidance system also did not activate. Because the vehicle had no braking capability at the time of the incident, the occupants and nearby pedestrians were placed at risk of serious injury. On may 10, 2026, the vehicle was taken to a Chevrolet dealership for inspection. The dealership has been unable to reproduce the issue, and no mechanical defects or diagnostic trouble codes related to the incident were identified. On may 13, 2026, the issue was escalated to the gm technical assistance center (tac) for further review, and the vehicle remains at the dealership awaiting a response to the tac case. The dealership acknowledges similar brake-loss concerns referenced in gm service bulletins involving the 2025 chevy Equinox and other models, including bulletin n24471431, although they stated the bulletin does not apply to this specific VIN.
