2025 Honda Accord: adaptive cruise control problems

Filed Oct 21, 2026 · Driver assistance · OH

In XXX, the driver assistance and safety systems on my 2025 Honda Accord SE began failing repeatedly. While driving, warning messages would appear for the collision mitigation braking system, lane keeping assistance, adaptive cruise control, and automatic high beams, and these systems would become unavailable. This happened multiple times over XXX and XXX . I took the vehicle to Hugh White Honda in [XXX], four to five times for this problem. The dealer replaced the forward-facing camera twice under warranty, but the warnings and system failures continued after each repair. The dealer was never able to identify or fix the underlying cause. I filed a complaint with American Honda on XXX (case XXX). Because the safety systems on a nearly new vehicle could not be repaired, I traded the vehicle in on XXX, with approximately 17,000 miles. No crash or injuries occurred, but the vehicle repeatedly lost the use of its collision avoidance and lane keeping safety systems in normal driving, and the manufacturer could not repair the defect.

This incidence occurred twice, one year apart, under the same driving and weather conditions and on exactly the same route. On XXX, after departing [XXX], we were driving north on [XXX] near [XXX], with the adaptive cruise control set to 70 mph. Suddenly the dashboard displayed the warning, “Some driver assist systems cannot operate: Clear area shown,” and the Honda emblem indicator illuminated. Following the vehicle’s instructions, we stopped and cleaned the Honda emblem by wiping and rinsing it, but the warning remained. After we continued driving north on [XXX] for approximately three to four hours, the warning cleared without further action. The weather was clear and sunny. An identical incident occurred one year earlier, on XXX, along the same section of northbound [XXX] and under the same driving and weather conditions. Accord was also set to 70 mph with adaptive cruise control engaged. That warning again cleared on its own after a few hours. In addition, while driving in the left lane on XXX with adaptive cruise control engaged, Accord braked aggressively while passing semi-trucks traveling in the right lane, even though there were no vehicles ahead. This happened several times. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Dashboard shows that there is a problem with the adaptive cruise control system, lane keeping assist system, road departure mitigation system, and automatic high beams. Message occurs intermittently, usually lasting a few seconds, and goes away. Can happen while driving or while parked. Usually occurs a handful or times per day. Seems to happen more frequently when engine bay is warmed up. This is a safety issue because it suddenly and unexpectedly disables the advanced driver assistance systems. For example, while driving on the highway, cruise control and lane keeping assistance will turn off suddenly, forcing the driver to intervene with all of these systems at once. This also has other implications, like automatic emergency braking not functioning correctly to help prevent an accident. Vehicle has been brought to various Honda dealers a total of three times. A case has been opened with American Honda Motor Co, but no solution to the problem has been found.

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 contact owns a 2025 Honda Accord. The contact stated that while driving at 60 MPH, the vehicle intermittently stalled. While idling or utilizing cruise control, the vehicle suddenly accelerated to 70 after releasing the brake pedal. While entering the garage with her foot hovering over the brake pedal, the vehicle suddenly accelerated forward and crashed through the wall into the TV room. The brake light was flashing. There were no reported injuries, airbag deployments, fire or police report filed. The gas pipe was bent into the wall, but she was able to turn off the gas line. The vehicle was taken to the local dealer, who reset the computer and replaced the battery. The manufacturer was not notified of the failure. The approximate failure mileage was 6,090.

While driving in Adaptive Cruise Control, a vehicle in the other lane was slowing down and turning right, but my car started applying the brakes for no reason. This has caused panic for me, since it was a 45 mph zone, and it was OK.

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.
