I had the car to the dealer for a air conditioner condenser replacement (no accident) in which the had to remove the front bumper/grill. So about a week later I was on this street going home and hit the -/set button (for 25 mph cruise) and it displayed "Cannot Set Cruise:Too Close To Vehicle Ahead" message. Called the dealer and they said "If there is no failure codes, it is working". What can I do to fix this problem. 2020 Civic app. 30 k miles.
Take it back to the dealer and demand that they fix their shoddy workmanship. They screwed up replacing the grill and the sensor, obviously.
