At 25 mph the collision avoidance system unexpectedly engaged and braked with full antilock vibrations when there was no car within braking range. The car behind me braked hard and an accident was fortunately avoided. This occurred after dealing with the dealer over several days regarding phantom collision avoidance cautions occurring on a daily basis. The vehicle also braked autonomously without any car in front of it earlier in the evening.

The contact owns a 2018 Honda Odyssey. While stationary, the vehicle would not turn off when prompted. On more than one occasion, all of the doors failed to open when prompted by the key fob. In addition, the brake mitigation engaged with a visual and audio alarm; however, there was no other vehicle around. Furthermore, the instrument panel indicators did not illuminate when the vehicle started and the cross-traffic monitor malfunctioned and had to be turned off. Del ray Honda (2500 South federal highway, del ray beach, fl) was made aware of the series of failures. The battery and the tuners were replaced on the vehicle, but the failures recurred. The manufacturer was made aware of the failures and provided the contact with case number: [xxx]. the failure mileage was 636.

On Saturday, 1/27/18 at 9:17am mountain time we were driving in a residential neighborhood following a silver SUV. As we approach an intersection with a green light, the SUV in front of us turned on their blinker to slow down to make a right turn. We were following behind at a safe distance. The SUV slowed down considerably to make the turn, but we remained behind at a safe distance as the SUV made the turn. The automatic collision detection system on our Honda Odyssey flashed a warning, as I've seen before, and the warning was appropriate given the situation. The SUV completed its turn and I reapplied the gas in the intersection. As I did so, the vehicle automatically braked, very hard, causing us to almost come to a complete stop in the intersection. I assume that we were traveling at a speed of appx 15 miles per hour as we entered the intersection. We were almost rear-ended by the car behind us (who honked at us, and with good reason). There was absolutely no need for the automatic braking to engage in this situation. Furthermore, the braking would have happened much too late to avoid a collision had one been imminent. The feeling of losing control of driving your own vehicle is extremely unsettling. While I like the idea of the automatic braking feature, this event is incredibly concerning. No one was hurt and nothing was damaged luckily. But, this easily could have caused a significant accident.
