2026 Honda Odyssey: false forward collision warnings

Filed Nov 1, 2026 · Driver assistance · KY

The Forward Collision Warning (FCW) / Collision Mitigation Braking System (CMBS) have almost gotten me into 3 accidents in the past year. I bought the car brand new and it now has almost 13k miles. All three incidents have been when traveling at speed of 35-45 on divided highways with turn lanes and stop lights when passing large vehicles. The video clips I will upload unfortunately does not have volume but the brake sign pops up on the dash and the cat beeps loud and then slams on the brakes for no reason. Even if those vehicles were in my lane, it would have stopped me too late as you can tell by how the car dips in the videos. I don't want to turn off the "safety" feature in case something does actually happen in front of me but its put my family in danger more than it has helped. I was told by honda when it happened the first time to clean the glass in front of the cameras but they were clean. They dont seem to want to take responsibility for this. I see this issue on the 5th gen Odyssey group on Facebook often which ahs finally prompted me to come here and file this incident.

Vehicle: 2026 Honda Odyssey EX-L, VIN [XXX] (leased). My prior leased Odyssey (2025) was totaled on [XXX], when its Lane Keeping Assist malfunctioned at highway speed: the steering became unresponsive, the vehicle drifted out of lane, and it crashed into a concrete barrier. I filed the federal safety agency complaint 11744403 for that incident. That complaint also documented Adaptive Cruise Control surging and a dealer visit that found nothing wrong. This leased 2026 Odyssey has a recurring Adaptive Cruise Control defect. After stopping at a red light with ACC engaged, a light tap of the accelerator to resume has caused sudden unintended acceleration, followed by a loud beep, ACC disengagement, and loss of propulsion. This occurred [XXX] ([XXX], rush hour traffic) and [XXX] (about 5:01 PM, [XXX]). On [XXX], the forward collision warning repeatedly alerted to a vehicle ahead when no vehicle was present. I brought the vehicle to Honda of Cleveland Heights on September 9, 2026 to report these issues; the dealer was unable to reproduce or identify the problem. Sudden acceleration toward the slow-moving vehicle ahead and unexpected loss of propulsion in moving traffic are severe safety hazards. The defect spans two vehicles, which points to a systemic Honda Sensing issue rather than an isolated fault.

I own a 2026 Honda Odyssey Elite. The vehicle has unexpectedly applied the brakes while driving even though there was no vehicle, pedestrian, or obstacle in front of me. The braking event occurred without warning and without any legitimate reason for the Forward Collision Avoidance system to activate. I first reported this issue to my Honda dealership on June 2, 2026 and again during subsequent repair visits. Although the dealership was initially unable to duplicate the concern, the issue remains unresolved. Unexpected braking at highway speeds creates a serious safety hazard because it increases the risk of a rear end collision and could cause other drivers to take evasive action.

This is a report on a design flaw- not a failed component- in the 2026 Honda Odyssey's "smart" computer automated safety features, including automatic braking, lane departure, and forward collision warning systems. There have been two types of incidents. These incidents have been repeated on this vehicle dozens of times in our first year of ownership. These incidents are potentially very dangerous because they involve erroneous automatic braking at interstate highway speeds. Unexpected erroneous braking at interstate speeds is a good way to cause a rear-end collision or loss of control. 1. Automatic emergency braking due to erroneous lane departure detection. On interstates in Arizona at highway speeds of 65 MPH, the vehicle's lane departure detection system throws erroneous warnings when it sees non-lane markings on the roadway, such as tar sealant strips or seams between pavement sections. This has resulted more than once in the vehicle erroneously applying emergency automated braking to slow the vehicle. This happens even when lane assist and adaptive cruise control are turned off by the driver. 2. Erroneous automated braking while overtaking another vehicle. On interstates in Arizona at highway speeds of 65 MPH, while passing in the left lane a vehicle that is moving much slower in the right lane (e.g. semi truck climbing a hill at 40 MPH), while using adaptive cruise control, automated braking is applied erroneously when there is no risk of a forward collision. The automated braking tends to kick in far earlier than a human driver would brake, and when there is no vehicle in the lane ahead, so it is unexpected and dangerous. This only happens while adaptive cruise control is activated by the driver.

While changing lanes to an off-ramp the Collision Mitigation Braking system suddenly activated along with a collision warning beep even though there were no automobiles nearby to trigger the warning. No cars in front of me and no cars to the right of me in the exit lane. My car immediately braked and tried to steer back into the main roadway, away from the exit lane. The lane departure light did also come on due to me not using a turn signal prior to the lane change, but there was nothing else around to trigger a proximity alert nor to respond to.
