NHTSA Complaint #11538465 — 2023 ACURA INTEGRA

Was driving at 75 to 80 mph speeds on interstate, and had approximately 4 to 5 seconds (400 feet+ at 75 mph) of clearance ahead of me before the next car. I had cruise control enabled and the adaptive cruise control was on the closest setting. Weather was clear and sunny and there were no visibility issues. The nearest vehicle in front was far beyond the ACC clearance zone. Suddenly the collision mitigation braking enabled and the car braked, beeped, and the warning light flashed. The car slowed suddenly from 75-80 down into the low 60mph range. I then had to tap the brake to disable or acknowledge the warning, resulting in another sudden brake. The vehicle has not yet been inspected by the dealer but I have contacted them. Safety of myself was at risk of sudden high speed braking or flipover if I had been in a turn. I also could have been easily rear ended. This happened twice in an hour span on the same drive. I believe both times this happened, the nearest vehicles in front were full size motorcycles.
