2017 Honda Accord Driver Assist & ADAS 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 working fine as intended up until the very day it failed.

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

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 or loss of control. I request that NHTSA investigate this incident and ensure Honda provides a permanent fix or recall.

There has been a recall on newer cars for the loss of power this is a similar to that problem.

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

This is an ongoing problem - -- On startup, the vehicle reports 4 system warnings that shut off the cruise control and ABS brakes as well as the other safety systems. This is an intermittent problem. -- The dealer states that the camera is dead and wants $2,500 to replace and calibrate it. This is a common response from dealers I see in all the forums. -- I have found a work-around that is not documented in forums yet. -- If we keep our foot on the brake until after the electronics start sequence finishes, no errors EVERY TIME -- If we take our foot off the brake when the car starts, but before the electronics finish, we get errors every time. This is a dangerous, high-frequency, extremely expensive problem if we follow the dealers suggestions. I do not know what the root cause is, but I know it is not a $2,500 problem. And, I am very concerned about the people driving without the safety features due to the excessive and unnecessary cost.

The contact owns a 2017 Honda Accord. The contact stated that there was a failure with the Adaptive Cruise Control (ACC) and Lane Keeping Assist System (LKAS) system. The contact stated that while driving at an undisclosed speed, the LKAS and Adaptive Cruise Control messages were displayed. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 150,000.

The problem with the LKAS manifests in the following ways: The system unexpectedly disengages without warning, failing to provide lane-keeping assistance. Erratic steering corrections occur even when the vehicle is properly centered in the lane, causing instability. The system frequently displays error messages indicating LKAS failure, requiring manual intervention to reset or disable the feature. At times, the system does not activate as intended, even when road conditions and markings are clear and well-defined. I have attempted to troubleshoot the issue by ensuring that the vehicle’s sensors and cameras are clean and unobstructed. However, the problem persists. I have also reported the issue to a Honda dealership, but they have not been able to provide a definitive resolution. This malfunction creates a serious safety concern, as an unpredictable LKAS system can lead to unintentional lane drifting or sudden corrective actions that may startle the driver or lead to a loss of control. Given that LKAS is a key component of Honda's driver-assistance technology, I believe this issue warrants further investigation by NHTSA to determine whether it constitutes a broader defect in the 2017 Honda Accord Hybrid model. I respectfully request that NHTSA investigate this matter and determine if similar complaints have been reported. If this issue is determined to be a widespread defect, I urge NHTSA to take appropriate action, including a potential recall or mandatory software update from Honda. Thank you for your time and attention to this matter. I would appreciate any updates regarding your findings and any further steps I should take. Please feel free to contact me at the information provided above.

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.

The contact owns a 2017 Honda Accord. The contact stated while driving at an undisclosed speed, the Forward Collision Avoidance Dynamic Brake Assist activated unexpectedly. The contact stated that the message “BRAKE” was displayed. The vehicle was taken to a dealer to be diagnosed. The contact was informed that the brake sensor was dirty and needed to be cleaned. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the dealer and was being diagnosed. The manufacturer was not made aware of the failure. The failure mileage was approximately 94,000.

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 talking to the technicians and doing research, this issue with the part has been a problem for Honda Accords 2013-2017 and many question if this should be on recall. I can think of reasons why Honda has not address this issue, but this could be a huge lawsuit if someone were to have this issue and not be able to replace this part, as could be us but we are fortunate that my brakes work last weekend. Please give this some attention and follow up with Honda. This part and replacement is also very expensive, amounting to around $2300 for most who had it done. And it also seems to happen for most people reporting around 85,000 miles. Thank you for reading this and I hope to get some attention to this issue for myself but also for other. I would hate for someone to die and for this to become a huge issue for Honda.

Hello I am proudly owner of honda since 2003 i only buy honda cars and recently on my 2017 honda we have issues with sensing system this error codes come and goes and i went to dealer and they told me to replace sensing Camara in front but I think it is just manufacturing defects because error code come and goes while you drive car. I cannot use any feature such as cruise control, forwarding collision warning, lane departure warning, lane keeping assistance and all features including in sensing system. I was on long distance trip and when i was coming back all those errors started coming.

The contact owns a 2017 Honda Accord. The contact stated while reversing, the rearview camera image was black. There was no warning light illuminated. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed nor repaired. The failure mileage was approximately 60,000.

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.

Rear back up camera stopped working @ around 40k miles. It is now always black when the car is in reverse.

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.
