NHTSA Complaint #11546199 — 2022 HONDA CIVIC

I owned 2 of these 2022 civics equipped with Honda's Collision mitigation braking technology. This is the year they removed the forward radar and relied only on a single camera unit. I was involved in a rear end collision where I was the rear ender even with the distance setting on the furthest setting. The accident was on the highway at about 40MPH. A vehicle Merging on to the highway stopped in front of me in my lane. I was using adaptive cruise control. I can tell you the responsive of this system had me worried from in several other situations I was in. Not only did the adaptive cruise fail detect and slow the vehicle based on the vehicle in front of me, the safety system did not make any attempt to slow the vehicle and no detection was made by the system until about .2 seconds (or about 6') prior to the actual impact. I investigated the safety systems logs with a Honda mechanic by connecting a device to the OBD2 port and downloading the logs to a computer to verify indeed it failed to properly detect any obstacle until it was far to late. This seems to be a concern other Honda drivers have expressed as well with this revision of their Collision mitigation braking system. I believe they market as if this and the adaptive cruise system are features you can rely on to keep you safe and while I understand it can not account for every situation this was a perfectly clear day in Arizona at about 5:30pm in moderate day light. I believe this system is dangerous and has serious flaws that do not properly detect vehicles in front of you in many situations is extremely slow to react in almost every situation. I attempted to upload these logs but you do not accept the file format they were exported in. If I can send these another way please let me know.
