NHTSA Complaint #11704801 — 2024 CHEVROLET COLORADO

Vehicle: 2023 Chevrolet Colorado Trail Boss Mileage: Approximately 14,000 miles I am submitting this complaint because the ABS braking system on my vehicle activates unexpectedly and causes a temporary loss of braking when driving over uneven pavement. When braking over potholes, bumps, or rough road surfaces at low to moderate speeds, the ABS system engages even though traction is available. When this happens, brake pressure is reduced to the point where the vehicle does not slow as expected. The ABS warning indicator flashes briefly, and there is a noticeable delay before normal braking resumes. This behavior has occurred multiple times in normal driving conditions on city streets, not during panic stops or slippery conditions. The issue feels most pronounced when approaching intersections or slowing in traffic over broken pavement, where consistent braking is critical. The momentary reduction in braking force significantly increases stopping distance and creates a safety concern. The vehicle has low mileage, has not been modified, and is maintained as delivered from the manufacturer. There are no warning lights remaining on after the event, and the issue appears to be related to ABS calibration rather than driver input or road conditions. This does not feel like normal ABS operation and gives the impression that braking is interrupted at the exact moment it is needed. Given the frequency and repeatability of the issue, I believe this represents a potential safety defect that could contribute to a collision, particularly in urban driving environments with uneven road surfaces. I am submitting this complaint to document the issue and to request that the ABS braking behavior on this vehicle be reviewed for safety.
