Owner complaint summary

While driving at various speeds, including highway speeds, the vehicle intermittently fails to slow down when the brake pedal is applied. On multiple occasions, the brake pedal was pressed but the vehicle did not respond appropriately and continued moving forward. On December 1, 2025, while traveling at approximately 65 mph on the interstate in rainy conditions, the vehicle began making a grinding sound and started sliding instead of slowing down. The vehicle briefly lost the ability to decelerate, creating a near-collision with a semi-truck. On December 22, 2025, the issue occurred twice in one day. While attempting to brake at a stop sign and in traffic, the vehicle did not slow down, nearly causing collisions with vehicles in front and adjacent lanes. In the instance where approaching the stop sign where a vehicle was stopped, the dashboard flashed “break” while I was breaking as hard as I could. Warning lights and sensor-related alerts have appeared intermittently prior to and during some incidents. The issue has continued intermittently, including additional incidents where the brakes were either unresponsive or overly sensitive. They do not respond in a consistent or predictable manner, making safe driving nearly impossible. This problem places myself and others at significant risk of collision due to loss of braking control. The vehicle has been taken to multiple dealerships for inspection. The problem has not been successfully replicated, and no repairs have been performed to resolve the issue. Dealership documentation includes customer reports of “NOT BRAKING” and brake malfunction concerns.
