NHTSA Complaint #11469344 — 2020 HONDA CIVIC

When driving at highway speeds with adaptive cruise control, vehicle will slow down or brake without any object/vehicle ahead. This usually occurs at curves, with no vehicles in current lane. I would then need to immediately step on the acceleration in order to continue highway speeds. This may cause unnecessary stress on the vehicle due to constant issue occurrence. At times, a blinking warning message from the emergency braking system will appear on the dashboard during these conditions. This causes a safety issue because cars in the back will not expect braking/slowing down when there isn't any obstruction from all perspectives. This is dangerous on the highway due to the increased driving speeds of surrounding vehicles. I have not taken it to the dealer due to the vehicle being out of warranty, however it has always had this issue. Vehicle was bought new at dealership.
