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 the federal safety agency 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 the federal safety agency 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.

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
