2017 Honda Accord Driver assistance Problems

The car hit the brakes automatically at 70MPH when passing on the left. There was absolutely nothing in front of the car that should have triggered the CMBS.

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.

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

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.

While pulling into a parking spot my car unexpectedly accelerated. Brakes were unresponsive even after placing both feet on the brake pedal. Vehicle stopped only after I hit a tree. Engine continued to rev at which point I placed the vehicle in park and shut off the engine. Although the impact of the crash was severe my 1airbag did not deploy.

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!

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.

Currently own a 2017 Honda Accord Sport just over 100k miles, regularly maintained and serviced. All of a sudden my vehicle takes longer to start and the most shocking issue is that I was driving to work as normal and when I went to accelerate onto the interstate my vehicle suddenly started jerking and it seemed as though my vehicle was not getting fuel even though I was pressing the accelerator. I had to get off the interstate as I was almost hit by other vehicles merging onto the interstate. It is very frustrating that other trims of Accords are included in the recall except this model. This recall needs to be revised to reflect all models for all owners. I literally almost lost my life due to this.

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.

2017 Honda Accord EX-L 4 Door Sedan 4 Cylinder 2.4L While driving my car I noticed shaking then my car dropped down to 10mph on the highway. when I pressed the pedal to speed up my car started jerking and did not go any faster. all the lights came on my dashboard including ABS. Me and my child safety was at risk because i was doing 10mph on a 45mph highway. we could have been hit. I took my car to the dealer they told me I'm not the only one having this problem with the ABS module and the part is on back order. So that mean there is a defect in the part that's why they cant get everybody need it. I brought it to the dealer they told me its nothing they can do. Not even test the part. i had a message about vehicle stability. maybe about 2months ago.

2017 Honda Accord V6; Vehicle Stability Assist (VSA) Module went bad and it needs to be replaced but Honda is unable to provide quick fix or a replacement part because it is backordered and they don't know when they'll have it in stock even when I am willing to pay for it upfront. This is causing my car to go out of control on wet roundabouts or when merging from interstate to local roads w/ good Tires condition and within speed limit.

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 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
