Summary of Complaint
Unexpected Automatic Emergency Braking Activation at Highway Speeds in Cold Temperatures. Description: I am reporting a safety issue with a 2023 Mazda CX-30 involving the collision avoidance / automatic emergency braking system. While driving at highway speeds, the system activates a forward collision warning (audible alert and dashboard indicator), followed almost immediately by automatic braking, even when there are no vehicles, obstacles, or pedestrians ahead. Conditions When Issue Occurs: * Ambient temperature: below ~40°F (4°C) * Road conditions: cold, often icy or snowy * Speed: highway speeds 45-75 * Environment: clear roadway, no visible hazards * visibility : clear System Behavior: * Audible warning and visual alert activate * Automatic braking occurs approximately 0.5–1 second after the warning * No obstacle is present to justify intervention Safety Risk: This presents a serious safety hazard because: * Sudden braking at highway speeds creates a high risk of rear-end collision * The warning-to-brake interval is extremely short, leaving little time for driver override. * Occurs in low-traction conditions, increasing risk of loss of control. * The event is unexpected and not predictable by the driver. Frequency: * Occurred multiple times under similar cold-weather conditions. * Appears repeatable based on temperature range. Attempts to Resolve: * Sensors/camera appear clean and unobstructed. * No prior collision damage to the vehicle. * Issue persists despite normal operation otherwise. * Similar reports observed from other owners in online discussions. This is not a one time occurrence, in the section below, i noted the last event but this is a daily occurrence in temperatures below 42F.
