NHTSA Complaint #11694400 — 2021 HONDA ACCORD

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle’s collision avoidance automatic braking system is malfunctioning. It engages unexpectedly while the vehicle is moving with normal traffic flow. The system is still installed and fully available for inspection upon request. How was your safety or the safety of others put at risk? The automatic braking system activates suddenly and without cause while I am driving at typical speeds (approximately 40–60 mph) with the flow of traffic. This unexpected braking creates a serious risk of rear-end collisions, both endangering me and putting other drivers at risk of crashing into my vehicle from behind. Has the problem been reproduced or confirmed by a dealer or independent service center? I have reported the issue to the dealer, but they have been unable to replicate the problem during their inspections. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? No, the vehicle and its braking system have not yet been inspected by the manufacturer, law enforcement, insurance representatives, or any other third parties. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No warning lights, messages, or other indicators were present before the issue occurred. I purchased the vehicle last month, and the problem with the collision avoidance braking system has been present consistently since then.
