Over the last three weeks, there were 3 incidents where the emergency braking system spiked the brakes when there was no reason. There was one incident where the lane departure spiked the brakes for no reason. Over the first 5 years owning the vehicle, this never happened. The first incident was going around a curve on a 2-lane road I travel at least twice a day. It sometimes beeps for cars in the other lane, but has never spiked the brakes until now. The car in the other lane was not over the line. There was a car behind us and they almost hit us due to the rapid braking. Incident 2 was on a straght road when there was a right lane closure with orange cones gradually blocking the lane. I started moving to the left lane well in advance and was most of the way in the lane when the brakes spiked. There was no oncoming traffic, but a car behind me had to brake hard to avoid hitting me. Incident 3 was similar to Incident 2, except there was a box in the road. With a straight road and no oncoming traffic, I was fully in the left lane, avoiding the box, when the brakes spiked. The 4th incident involved spiking the brakes with a lane departure warning. I was going around a curve that I travel at least twice a day. The road was clear and no traffic coming the other way. Going around the left curve in full control, the right lane departure warning sounded and spiked the brakes. The brakes had never applied before in a lane departure scenario. I took the van to the dealer and they made it sound normal, like four improper emergency braking incidents in 3 weeks was a regular occurrence. They tried to duplicate the issue and checked the computer for codes, but found nothing. This does not seem normal to me and is a safety issue that could cause an accident if the car spikes the brakes for no reason like this and someone is following closely, not expecting me to stop.

In September 2021, I started occasionally receiving the error message "Collision Mitigation System Problem" on my dashboard. It would appear and quickly disappear. At that time, my car shut itself off when I came to a full stop at traffic lights and stop signs 3 different times. The car would boot back up, but it happened to me in the middle of intersections. I took the vehicle into the dealership and they told me it was the battery. I had the battery replaced, but with time, the "Collision Mitigation System" error reappeared along with other messages, "Engine Management System Problem" and "Road Departure Mitigation Problem." During this time, my car would brake on its own occasionally, happening 6 times in total, when there was no threat of a head-on collision. Three of these incidents happened in the middle of intersections with cars all around me and in one instance, my car come to a screeching halt on its own making me terrified that the car behind me was going to crash into me. The last straw was as I was driving to my child's school and when I came to a curve in the road, my steering locked up completely, not allowing me to turn with the curve. I was able to slam on my brakes and keep myself from crashing, but it was very dangerous. At the same time, the same error messages were flooding my dashboard. That is when I drove my just 3 year old car back into the Honda Dealership and told them they must fix this before I put my child back into that car, and my car still sits there. The dealership informed me that my Collision Assistance Camera that is integral to the Honda Sensing safety mechanisms is "faulty" and will cost me $1,500-$1,700 to repair. I see online that this is being investigated in 2017-2019 Honda CRVs and 2018-2019 Honda Accords sedans. I implore you to also investigate this same system error in 2019 Honda Odysseys. The Odyssey is a family car, but yet I am now scared to drive my family in this vehicle for fear of it causing a collision.
