2017 HONDA PILOT Forward Collision Avoidance Warnings Problems

On Feb. 03, 2026 around 5:30 pm, driving 290 west going 65 mph. No cars on either side of me and the next closest car 6 lengths of me, my car slammed on the brakes and alarmed. The sudden braking lasted 1-2 seconds.

Emissions System Problem- UNKNOWN reason

2017 Honda Pilot Errors: lane keeping assist problem LKAS adaptive cruise control problem ACC road departure mitigation system problem RDM collision mitigation system problem CMBS or Collision Mitigation Braking System

Multiple lights, for ACC, Lane Departure, Forward Collision Warning, and Lane Keeping Assistance system. None of the systems works. Safety of myself and others put at risk due to systems not working and preventing collision. The problem was confirmed by the dealer. Multipurpose camera not operating, required replacement of camera for systems to operate.

ACC, LKAS, collision avoidance, and other safety features lights all came on at once.

Four warning lights have been on for the past week. Brought it to Honda for diagnosis and repair, and they state that the multi-purpose camera has failed and will need to be replaced at a cost of $1,900. This is seems like a huge safety issue and, after reading several forums, appears to be a global issue.

When Engine goes idle during the brief traffic stop, Collision mitigation warning shows on and goes off quickly, sometimes causes the engine to not turn on during the times. Problem is so intermittent and hard to track as it is random behaviour and comes on for milli seconds in terms of warning on the dash board.

The front facing camera was working intermittently. When it wasn’t working all the advanced driving features would not work. After several months the car would intermittently go into limp mode per the dealership due to electrical confusion with all the codes/lights from the camera malfunction and shift while driving into neutral nearly causing me to have an accident while making a left hand turn. The camera had to be replaced at a large cost and they said it was not able to be repaired despite the fact that it worked perfectly 10% of engine starts

During the last week, alerts would appear on my dash from the Collision Mitigation Braking System and Road Departure Mitigation System. These alerts will appear while driving at 30mph on a city street. When the alerts appear, the brakes are activated and the steering wheel locks up. The alerts immediately clear but it is very alarming to the driver and passengers. Yesterday while parallel parking, in the mist of reversing into the parking space, the systems triggered alerts along with a transmission alert. The system immediately put the vehicle into park and would not permit the change of gears. While halfway in the parking spot with the front of the vehicle sticking out into on coming traffic, I was forced to completely turn the vehicle off, wait about 3 minutes before turning it back on. This allowed me to complete parking the vehicle in the spot.

Over the past couple months, while driving the collision mitigation braking system would activate for no reason. As of 2 weeks ago, now my collision mitigation braking system does not work and on the dashboard display it shows collision mitigation system problem. I have read on multiple Honda boards and general internet search on this issue, many people are having the same issue. This issue has been affecting people for maybe 5 years. I’m wondering why this is not a safety recall for the Honda vehicles.

Auto engine idle continues to be problematic. Leaving me stranded in intersections and unable to restart my vehicle for minutes. Today when it happened it turned off my collision detection feature. I have taken to dealership several times, once they replaced fuel injectors due to related recall but since they show no issues.

On many occasions, when the vehicle is stopped (at a light or in gridlock), when I remove my foot from the brake to apply the gas, the engine stops and the vehicle shuts down all systems (audio, nav, etc). When this happens, for a very brief time (too short to get a photo) warning lights related to the collision and/or emergency braking systems flash. After those lights go away, the dashboard lights indicate that the vehicle is in neutral (not by my doing) and that I must press the brake, put the vehicle in park, and restart the vehicle. This process does not always work the first time and the delay of turning off and restarting the car, even when it does work, causes a dangerous situation in traffic. When this happens on a downward hill, my vehicle rolls forward as it “dies” and I am sometimes stuck in the...

Turned on the car back in May '22 and all my lights came on my dashboard for ACC, Collision, Lane Departure, Lane Keeping Assistant, Brake Assistance. I have taken it to two dealers and the problem seems to be the multi-function camera in the windshield has failed. Said it is safe to drive still without it, but now the Cruise Control isn't even available with this malfunction. Two months later my Transmission Problem light comes on. I take it in again and they say the multi-function camera being broken is triggering this warning light to come on. So I don't know if my transmission actually has a problem or if the multi function camera is breaking everything electrical in my car. Transmission drives funny but I can't prove anything because of the camera. If the car has been in the sun for a period of time the lights will not...

The camera assembly - monocular unit mounted in front of the rear view mirror just stopped working. It’s responsive for a multitude of safety systems, such as: Automatic Emergency Braking, Collision Mitigation, Lane Departure Warning, Adaptive Cruise Control and Lane Keeping Asst.

I returned from work at approximately 5 pm on 03-01-22. As I prepared to enter my garage, I realized I could not pull in due to objects in the way. I put my foot on the brake, and as I planned to reverse, the car lurched forward and into the side of my house! No warnings, no air bag deployment, and a sudden lurch, stopped only by my (less than 2 year old, custom-built) house! Garage door would not close after the car was backed out. Car was towed to Performance Honda in Fairfield, Ohio. No codes were recorded and they did not indicate reproduction or attempt to reproduce the problem. They reset all computer systems in the vehicle. The included photos also show the skid mark on the driveway, indicating to us that the brakes were on when the car "lurched" into the house.
