NHTSA Complaint #11495496 — 2021 HONDA ODYSSEY

Exiting a construction zone (I-70 westbound near Mt. Comfort, Indiana) at approximately 60 to 65 mph, our 2021 Honda Odyssey, without warning, momentarily applied unwarranted automatic emergency braking. The brakes were actuated for (an estimated) one second and resulted in an abrupt (approximately) 10mph reduction in speed. A large SUV traveling directly us was forced to take immediate action by making a sudden lane change in order to avoid a serious collision. The involuntary braking action on the part of the vehicle placed the passengers of both vehicles in grave danger. The only warning indication provided by the vehicle was an orange-box “BRAKE” warning displayed on the dashboard and the accompanying warning beeps, both simultaneous to the actual brake actuation. No indications or warnings appeared prior to or after the actual braking. No obstacle or object on the roadway was visible to either the driver or front seat passenger. All traffic lanes were clear for a minimum of 100 yards ahead of the vehicle. Weather was clear and dry. The pavement was dry and clear of any debris. The construction zone where the incident occurred carries both east and westbound traffic on the normally westbound (north) side of the expressway. The left side of the traffic lanes are lined with continuous, concrete “Jersey” barriers. The incident took place at the western end of the zone, at the point where the westbound lanes expand from two to three lanes. This is approximately where the left-side parallel-to-traffic barriers end and a small, separated section of angled-to-traffic barriers is revealed, along with some other barrier sections in the median area between the roadways. This incident (November 26, 2022) was the second time this malfunction has occurred in same vehicle in approximately the same area on I-70. On August 11, 2022, an essentially identical event took place under similar conditions. The vehicle has not been inspected by Honda or any other authorities.
