2023 Honda Accord Driver Assist & ADAS Problems

My automatic braking system randomly halted me to a stop in the middle of a clear road and almost caused the person behind me to crash into me even though they were back away from me a safe distance. This has happened several times now and it scares me a lot every time it happens. Makes me want to sell the car. I looked it up and saw that many other people online have had an issue with this feature. I also learned there’s no way for me to fully disable the feature which is frustrating. I can only turn it off manually each time I turn my car on. This feature is not safe and has put my life at risk way more times than it has been helpful.

My car automatically braked almost causing the car behind me to rear end me for no reason.

Driving the vehicle at highway speeds the large orange “Brake” warning illuminates and flashes, and the brake activates. This has happened approximately 5-6 times since I have owned the car. This started within 2 months of purchasing the vehicle. The dealer has tried replacing the front camera and I have changed the battery. None of this has fixed the issue. According to my Innova 5610 code reader, there are 32 pending codes for the Electric Brake Booster, including bring temperature too high, brake booster driver, circuit, overheat, brake pedal stroke sensor component, internal failure, brake pedal stroke sensor one circuit short to ground, brake pedal stroke sensor one circuit short to battery or open, brake pedal stroke sensor two circuit, short to ground, brake pedal stroke sensor two circuit short to battery or open, sensor voltage, a short circuit to ground, driver seatbelt sensor, vehicle, communication bus a performance, vehicle communication bus C performance, lost communication with the ECM/PCM A, F – can malfunction PCM – TCM, can communication failure with driving support system control unit, lost communication with vehicle, dynamics, control, module, lost communication with park brake control module, can reception error SRS, can malfunction ECM/PCM gauge control, module, invalid data received – signal has too many transitions/events, invalid data received from transmission, control, module – event information, invalid data received from vehicle dynamic control module event information, electric parking brake system malfunction control module – internal electronic failure, battery voltage circuit voltage below threshold, battery circuit voltage above threshold, and control module input power a circuit open. After I changed the battery and took the vehicle to the dealer for recalibration they mentioned the pending items, but did not do anything about them or record them on their paperwork.

To Whom It May Concern, I am submitting this complaint to report a serious vehicle safety issue involving a Honda vehicle that was under a lease agreement. From the start of the lease, the vehicle suffered from repeated malfunctions of its safety and proximity sensors. These issues were reported, and the vehicle was taken multiple times to an authorized Honda dealership. Despite these efforts, the problem was never resolved. I later discovered that the vehicle had an active safety recall that was never disclosed to me, even though the vehicle had been serviced at the dealership on several occasions. This failure to inform me of a recall represents a significant safety concern. Subsequently, the vehicle was involved in an accident that resulted in a total loss. I firmly believe that the unresolved sensor failures and the lack of recall disclosure played a role in this incident. I am submitting this report so that NHTSA may investigate this matter and determine whether there is a broader safety issue affecting other vehicles. Thank you for your attention. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The idle stop system every time I turn it off it will automatically come back on and this feature makes me feel as if when it keeps doing that after I’m constantly turning it off from it popping back on that sometimes it don’t want to catch speed. I for see this being a long term issue if all Hondas are like this .

On December 9, 2023, while driving my brand new 2023 Honda Accord Hybrid Touring HPD package on the highway during snowy conditions at less than 50 mph less than 8000 miles on the odometer after my first oil change the automatic emergency braking (AEB) system suddenly and unexpectedly engaged with no obstacle, vehicle, or pedestrian ahead, causing the vehicle to skid uncontrollably and slam into a concrete highway barrier. The car was towed from the scene, and I was hospitalized for injuries sustained in the high-speed impact. The AEB component or system malfunctioned by activating without cause; it was inspected by police at the scene and I contacted Honda’s safety team to conduct an investigation. This unintended braking put my safety at extreme risk by inducing sudden deceleration and loss of control on a slippery highway, which could have endangered following traffic as well. The problem has not been reproduced or confirmed by a Honda dealer or independent service center since the vehicle was not repaired. Police inspected it at the crash scene and issued me a ticket for “driving too fast for conditions” despite my explanation of the sudden braking; no manufacturer inspection of the AEB occurred, though I contacted Honda’s safety team and they attributed it to not following the owner’s guidebook without further review. Prior to driving, all dashboard warning lights illuminated unexpectedly; I turned the vehicle completely off, restarted it, and the lights disappeared with no further symptoms until the AEB engaged abruptly on the highway. This matches ongoing NHTSA investigations into Honda Accord and CR-V vehicles for braking problems, including false AEB activations.

Was driving around 70 mph all the Honda safety equipment started to fail(cruise, power steering, parking, 7 different warnings) brought to dealer is still there car has been OOS for a week.

March - mpg display rapid fluctuations causing car to use more gas than should. It resolved itself a few weeks after taking it to dealership and them saying it not a problem but I don’t think it should’ve been like that. August 29 - acc stop sensing car in-front me immediately after turning on indicator and sped up resulting in and accident, luckily no one was injured. September 7 - while reversing into a frequently used parking spot the car thought ‘the wall was moving’ it has never done that before. Automatic collision braking activates when vehicle or object is nowhere near the car and almost caused accidents multiple times. I thought this was natural at first but then I heard of others having the same problem.

The car's dashboard will flash break and will use its emergency braking system to stop when there isn't anything in the way. Thus, the car stopping short and potentially causing an accident while there isn't a reason to break.

The car has been showing a system update error and a message to please see the dealer when started from about 1000miles after I purchased it. I contacted Honda Service Center in Irving over a month ago and they mentioned that Honda is aware of this problem and is working on a solution soon. I have since not been contacted and am having to visit back there almost weekly to get a solution to this. These cars are new and almost entirely automatic and this is becoming an area of concern for my safety as well as my families safety. Over time I have also noticed the automatic break system signaling me to break when there is no obstacle ahead or even in the vicinity. Not to mention that the adaptive cruise control causes a hard break while next to cars in the nearby lanes even when they are not merging or coming within my lines.
