NHTSA complaint #11736781

Owner complaint summary

While driving to store for errands today, 09May26, I came to a stop at a red light with intent to turn right next. I turned on my right blinker and turned a bit to the right and rolled forward to gain visibility to my left as I came to a complete stop. There was a car coming from the left that was preparing to turn left. I observed that car turn on its left blinker, and slow down while entering its turn. I confirmed the intersection was clear and there was nothing in front of me. I applied the gas, then looked left to confirm the other car was completing its left turn. While I was slowly accelerating, but before my eyes returned to the road ahead of me, the accident avoidance system sounded an audible alarm, I think I recall seeing an orange dash warning, and the system seemed to simultaneously trigger a hard brake apply. This was akin to a panic stop. I knew there was a truck approaching behind me. Although a bit stunned and dazed, I recovered as quickly as I could, and continued to complete my right turn to make sure that vehicle did not collide with me. The hard brake apply was so sudden, my head and body pitched forward (as much as permitted by the seat belt). After returning home, I realized my right shoulder was sore, presumably from the brake apply. I worry that this system could trigger the brakes like this at a much higher speed, in a turn, or with my children driving the car (they are just [XXX] and [XXX] old). I have since reached out to the dealership that I purchased the car from for assistance (LaFontaine Honda in Dearborn, MI). I just bought the car (used) last Friday, 5/1. I am a technical project manager that has supported automotive brake development projects for multiple companies and customers for 26 years. I know how these systems are supposed to work, and this one seems flawed, and potentially dangerous in my opinion. I would be happy to discuss further if NHTSA has questions.
