2016 Honda Accord: adaptive cruise control problems

Filed Sep 20, 2026 · Driver assistance · FL

My 2016 Honda Accord Touring has an intermittent failure of multiple Honda Sensing safety systems. The vehicle displays warnings for Collision Mitigation Braking System, Road Departure Mitigation System, Adaptive Cruise Control, and Lane Keeping Assist System. When this occurs, these driver-assistance and collision-avoidance features become unavailable. This is a recurring problem. In August 2023, an authorized Honda dealer diagnosed substantially similar symptoms. The technician documented DTC P2583-87, described on the repair order as “lost comm with the wave radar.” The dealer removed the bumper, tested wiring between the radar and camera, checked radar power and ground, and diagnosed a faulty millimeter-wave radar unit. The Honda dealer replaced the radar assembly with part 36802-T2A-A05 and performed radar aiming/calibration. The repair order states that normal operation was restored. I paid $1,422.08 for the repair and related charges. The problem has now returned and is intermittent. At times all systems work normally; at other times the multiple Honda Sensing warnings appear together and the safety systems become unavailable. I am concerned that a previously replaced and calibrated Honda millimeter-wave radar/safety system has experienced a recurring failure. I am requesting that the federal safety agency review this issue and similar complaints to determine whether a safety-related defect exists.

There were emergency lights on dashboard all of a sudden for Adaptive Cruise Control, Automatic Emergency Brakes, Collision Warning and lane departure warning. These functions aren’t functioning all of a sudden and claims to need attention although the car is only 6 years old

I was driving approx 70 MPH on the interstate hwy when I engaged the cruise control. Shortly after that the car began braking. Pressing the accelerator wouldn't disengage the cruise control. The car came to a complete stop in the middle lane of the interstate. Only after turning off the engine and restarting was I able to drive.

While on a trip driving on an interstate at 72 MPH, in busy traffic, with cruise control on, the engine stalled. I rolled to a stop on the shoulder, and the car didn't restart. Engine lights came on, but all electronics (radio, computer screens) were working. Honda towed (under warranty) to their nearest dealership. After checking out the car, and telling me it restarted and displayed no diagnostic codes, I was sent on my way. I was told it was safe to drive as there was no problem. Still on a trip, and about 500 miles later, I was again on the interstate passing a group of semi's on about a 5% grade, with cars in front of and behind me, when the engine stalled again. This time was much scarier as I was in the passing lane, and the right shoulder was blocked by a long string of semi's. It was dangerous trying to get to the right shoulder as there were cars in front of and behind me also. I was traveling at 78 MPH with cruise control on when this happened. The car restarted this time, and with it being a weekend and the service department closed, I continued home the final 550 miles (in the right lane) without incident. This was the 3rd time the engine has stalled. The first was when I was in heavy traffic on the interstate, in stop and go traffic. The temperature was 109, and at the time (car had about 10,000 miles on it) I attributed it to the temperature even though the car didn't overheat. It restarted immediately this car is the 6 speed (manual), 6 cylinder, coupe model.

The adaptive cruise control in my car malfunctions in rain/sleet conditions during winter months. A layer of ice forms over the sensors, and the car suddenly accelerates or maintains velocity without noticing the vehicle in front. It takes a few more miles and minutes till the acc is disabled warning pops up.
