2017 HONDA ACCORD Forward Collision Avoidance Automatic Emergency Braking Problems

The multifunction ADAS camera module failed due to "Internal Error" at only 9 years old. This means that critical safety systems such as automatic emergency braking/lane keep assist malfunctioned and could not assist with avoiding collisions. I took the car to the dealer and they confirmed the issue, and charged me $2000 to fix this critical safety system. I noticed that the new camera assembly has an updated part number, indicating that Honda might have been aware of this failure issue. I have also seen some forum posts online of others having this failure with their 2016-2017 Accords with Honda Sensing. Therefore I believe this should warrant a recall. When the failure first occurred upon vehicle startup a few days before I had it repaired, all these systems were disabled and there were multiple warning lamps on the gauge cluster and screen. Prior to this sudden failure, everything had been...

The camera failed on the car rendering all the safety features inoperable. The camera cost almost $2000 making it an expensive repair.

ALL THE PANEL LIGHTS ON THE DASHBOARD LIT UP. HONDA SAYS I NEED NEW INJECTORS FOR ABOUT $2000. THE CAR ONLY HAS ABOUT 66,000 MILES. THEY ALSO SAY A NEED A NEW HEAD UNIT, FOR THE ENTERTAINMENT SYSTEM. I HAVE HAD THREE OTHER HONDA ACCORDS BEFORE THIS, AVERAGING OVER 200,000 MILES. NEVER PROBLEMS LIKE THIS.

Vehicle: 2017 Honda Accord EX Mileage at incident: Approx 30,000 Date of incident: Dec 10, 2025 Description of problem: While my daughter was driving our 2017 Honda Accord EX, the Collision Mitigation Braking System (CMBS) suddenly activated without warning. The car slammed on the brakes even though there was no obstacle in front of her. This caused the vehicle to skid, but fortunately there was no collision or injury. There were no diagnostic codes found when inspected by an independent auto shop. The shop advised us to temporarily disable the CMBS system. This appears to be part of the ongoing issue of phantom braking in Honda vehicles, which has been reported by many owners and is currently under NHTSA investigation. I am concerned about the safety risk, especially since my daughter drives this car regularly. Safety concern: Unexpected braking at highway or city speeds could easily cause a rear-end collision...

All 4 warnings came on about a month ago - no safety systems & no cruise control at all. I could drive 50 miles and they'd go off until eventually they did not. Now I find through the forums that this is very common for the 2017 Honda Accord & Hybrid! And, the dealers knowing this are charging over $2,000 for a simple camera! So, they know these have a high failure rate, are not fixing them, and are price gouging us! Please help us all on the roads out there!

While driving my car suddenly felt like it was braking. The car beeped but no brake light appeared as when it thinks i am going to run into something. There were 2 incidents with nothing in front of me. One was at a low rate if speed and one was on a freeway. The car went back to normal after a second. The incidents were around 3 weeks apart

ON [XXX] my car while driving suddenly reported ABS brake system failure, together with that other warnings flashed Adaptive cruise, PS System (EPS) failure etc. With difficulty I was able to stop the car and pull over. Same day I called Honda service HQ and lodged a complaint Case number [XXX]. The car has 57,478 miles and is properly maintained. Honda suggested that I drive the car over to a dealership. I am unwilling to drive due to serious safety concerns. Another followup email was sent on July 8th to [email protected] but has resulted in no response. I am a [XXX] and even though its a serious safety incidence, Honda has shown no signs of concern . Please advise and help me out, the company should get it towed and fix the issue free of charge. Thank you INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C....

The contact owns a 2017 Honda Accord. The contact stated that while driving at various speeds, the emergency brake warning light would intermittently flash on the instrument panel. One day while at a complete stop, the automatic emergency braking system activated without incident upon depression of the accelerator pedal. The dealer was notified about the failure but offered no assistance. The manufacturer had yet to be notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 58,000.

On [XXX] the car was being drive from North Carolina to Ohio. The brakes failed in Fort Chiswell, VA, at 5:00 pm on [XXX]. Using the brake pedal did not slow the car, had to put gear selector in B, that slowed the car but did not bring it to a stop. Had to use the emergency brakes to come to a complete stop. This malfunction could cause a crash or could cause injury or death. The brakes failed a second time the tollbooth between Princeton, WV, and Beckley, WV. On [XXX] the car was towed to the Honda dealership in Beckley WV. The dealership worked on the brakes and claimed to have fixed the problem. On [XXX], after one hour of driving, now in Charleston, WV, the brakes failed a third time. The car was turned off and then back on and driven and the brakes failed a fourth...

On October 14, 2023, several lights came on after starting the car up, including the ABS light. This had not happened before. We had just had the car serviced for an oil change 2 weeks prior. We called friend who was a mechanic to see what we should do. Not long after we had reached out, we had a situation where we pulled out of our neighborhood and someone illegally turned in front of us almost hit us head-on. The only reason it didn't occur is because I put on breaks very quickly and stopped our car. We took my car to have to lights assessed today and found out that the lights came on due to the ABS Modulator going bad. We also found out that they do not have the part and that it's on backorder. That it has been this way for a year or so. After...

The adaptive cruise system on this vehicle will get you rear ended real fast. It applies the brakes whenever it feels like it, when you make a turn while passing a truck it will slam on the brakes so hard it tries to throw you thru the windshield and all you are doing is passing a truck in a turn The lane departure is dangerous because it fights you in a turn to the point you have to fight to stay in lane and it shakes the steering wheel which seems to me would be the last thing you want to have happen

The forward camera tied to ALL safety features (as well as cruise control) is defective. I have tried to replace at a Honda dealership twice since December of 2022; they tell me the part is backordered. Because the camera is defective, NONE of the safety features work; cruise control is also disabled. Failure to have the part available is creating an unsafe vehicle by prolonging repair. My car has approximately 120,000 miles.

I have a 2017 Honda accord, just a little over 5 years old and 73K miles. It has never been in a car accident and I bought it new from the dealer. Last month I started to have lights that showed my lane assist, adaptive cruise control, collision mitigation system, and road departure mitigation system were not functioning. I took my car to the dealer and was initially told that it was an SRS unit failure. Later, they changed and said the SRS unit is fine but the camera is damaged. Honda is considering this normal wear/tear and will not cover this repair even though the car has never been in an accident. The car will not pass inspection unless this is fixed. The airbags will not deploy until this is fixed and the car is therefore dangerous to drive. The camera is on back order and it will be...

All wrong lights came on the dash and all components had failed. Took it to the dealership and they weren't able to diagnose, they reset the system and said that if it failed again I would need to purchase a Honda battery as it had recently replaced with another brand. Everything worked for about two weeks until I was on the freeway with the cruise control set at 75 and suddenly the brakes took me down 35. Very frightening experience. Took it in again and they said I needed to replace the camera in the windshield at $1,900.00: my car only had 42,000 miles and 4 years old. Reluctantly, we replaced and paid for the camera and once again the cruise and lane assist failed a week later. My screen also appears to be defective as it goes black and pixilated and the dealership simply resets it and the problem...

When Driving the car it will occasionally Brake when another car is passing in the opposite direction My local Honda Service technician can find no problems. When we deactivate t he CMBS(Collision Mitigation Braking System) the problem goes away.

Traffic was traveling at around 55 miles per hour. The car in front had to make a quick stop to avoid hitting a flagger that could not be seen due to the sun. My car that is equipped with Hondas forward collision mitigation system did not respond. I pressed the brakes myself but did not stop in time resulting in an accident. The system does activate randomly while driving and will slam the brakes when no objects are in the path of the vehicle.

While driving on an interstate, I started reducing my speed as I was approaching my exit. Before I could exit, my car automatically came to a complete stop. I was rear ended by a truck that was behind me. There were no vehicles or objects in front of me. 911 was called. The passenger in my car had to be transported to the hospital. My car and the truck had to be towed away. No warning lights appeared. My insurance company will be inspecting the car at the tow shop. Everyone involved safety was put at risk. We are thankful we are alive because this could have been worse.

Driving on the highway with the adaptive cruise control, lane departure warning, auto emergency braking and lane keeping assistance engaged the vehicle will occasionally initiate an un-commanded, unreasonably abrupt brake application for seemingly no reason and often with no other vehicles in the vicinity. I've noticed Honda has issued a recall for 2018-19 Accords for this exact anomaly. It only stands to reason that my vehicle is experiencing this same defect as many of these systems are shared with the 2017 Accord. I won't use this feature as is because it seems unpredictably dangerous.
