Open the full vehicle complaint log (all categories)Problem Summary: While using the vehicle’s Traffic Assist / Adaptive Cruise Control (system that controls acceleration and braking in traffic), the vehicle unexpectedly accelerated toward a vehicle directly ahead as if no lead vehicle was present. This created an imminent rear-end collision risk. The issue occurred twice in the same drive. Incident Details: On 18 dec 2025 at about 5-15MPH/ “stop-and-go traffic”], I was driving with Traffic Assist / Adaptive Cruise Control enabled, which normally manages throttle and braking in traffic. I was following a semi tractor (no trailer attached). The semi was approximately 15–20 feet in front of me. While the system was engaged and operating normally moments before, the vehicle accelerated forward as if the lane was clear, despite the semi being directly ahead. I had to apply the brakes manually to prevent a collision. A short time later in the same traffic situation, the vehicle did it again—it accelerated toward the same type of lead vehicle and I again had to brake to avoid rear-ending it. During the second event, I observed the instrument cluster / driver display showing the lead semi incorrectly identified as a passenger car instead of a truck, and the display showed that “car” accelerating away, which was inaccurate and did not match real conditions. This suggests the system may have misclassified or failed to track the lead vehicle, leading to unintended acceleration.
The issue involves the adaptive cruise control and automatic emergency braking systems. When engaged, the system intermittently and unexpectedly applies full braking force while I am changing lanes on the freeway, even when no vehicle is directly in front of my car. This has occurred multiple times at highway speeds, causing the car to slam on the brakes abruptly, which poses a serious safety risk particularly when other vehicles are following closely behind. The issue most commonly happens when the adaptive cruise control is active, but it has also occurred occasionally when the system is not engaged. There are no consistent warning messages or error indicators before the event, aside from the brief flashing of the emergency brake light at the moment of braking. The problem has not yet been inspected or confirmed by a dealer, manufacturer, or independent service center.
