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 the federal safety agency 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)
2023 Honda Accord driver assistance complaints
Page 2 of 2: complaints 11 to 31 of 31, newest first, as owners wrote them.
The vehicle's suspension is excessively stiff and harsh since new, transmitting all road imperfections, bumps, and irregularities directly to the driver and passengers, causing discomfort and fatigue. Additionally, there is abnormal noise (clunking/rattling/creaking/popping) from the steering rack area, especially when turning the steering wheel at low speeds, over bumps, or when stationary. The suspension components and steering rack assembly are available for inspection upon request. This condition affects safety by causing driver fatigue, reduced comfort/control on uneven roads, and potential distraction from steering noise indicating a possible developing failure in the steering system. The problems have been inspected and repair attempted by authorized Honda dealers on multiple occasions, but the issues persist and have not been resolved. The vehicle or component has been inspected by dealer service centers.
Describe the Safety Issue: My 2023 Honda Accord (VIN: 1HGCY1F28PA010141) stalled in traffic due to electrical system failure. A certified Honda technician found undisclosed non-factory wiring, exposed wires, removed aftermarket alarm components, BCM communication failure, and multiple hard codes that cannot be cleared. The vehicle has serious electrical defects that affect engine communication and safety systems. These conditions create a risk of stalling, electrical fire, loss of power, and loss of control while driving. The defects were present at the time of purchase but were not disclosed. When did the issue begin? Stalled in traffic and warning lights appeared immediately after purchase. Is the problem reproducible? Yes. Hard codes and electrical malfunctions reappear after clearing. Has the vehicle been inspected? Yes. Inspected at Team Gillman Honda North. Technician documented unsafe wiring, BCM issues, and recommended teardown with an estimated repair cost of $2,686.86. Has the manufacturer been contacted? Yes, through Honda dealership service. They confirmed the defects are not normal wear and are related to altered wiring. Has the dealer been contacted? Yes. The selling dealer refused assistance and told me not to contact them further.
While driving, my 2023 Honda Accord Hybrid suddenly experienced a multi-system failure affecting: Road Departure Mitigation System Tire Pressure Monitoring System (TPMS) Vehicle Stability Assist (VSA) Hill Start Assist Electric Power Steering System Brake System (“Brake performance may be reduced”) All warnings appeared within seconds. The vehicle is available for inspection, and the incident is documented with multiple photographs. In addition to the system failures, the vehicle unexpectedly began to lose power while I was driving, causing it to slow down rapidly in active traffic. This created an extremely hazardous situation, including: Risk of being rear-ended since my vehicle slowed without warning Reduced steering assist Reduced braking performance Loss of stability control Inability to accelerate out of the way This combination could easily have caused a serious collision. I later learned that there is an active recall related to the systems that failed on my vehicle. However: I never received any communication from Honda, no letter, no email, no notice of any kind. I am extremely unhappy and frustrated about this. Had Honda informed me of the recall: I would have scheduled service immediately I would NOT have driven the car under normal conditions I would NOT have been exposed to this dangerous situation on the road The absence of recall notification directly contributed to my being put in a potentially life-threatening situation. A recall notification exists for a reason which is to prevent exactly the type of failure and danger that I experienced. Honda’s failure to notify me removed my ability to take preventative action. The issue has not yet been diagnosed or confirmed by a Honda dealer. I will be taking the vehicle in for inspection as soon as possible. No inspections have been conducted yet, but I have full photographic documentation from the moment the incident occurred. No prior warning lights, symptoms, or error messages occurred.
Summary of Incident: For approximately two years, my vehicle has experienced random electrical issues. All dashboard warning lights will flash at random times. When I take the vehicle to the dealership (Bell Honda), the problem disappears before it can be diagnosed. On September 27, 2025, and again on September 28, 2025, the vehicle completely stopped and shut off while I was driving. It would not restart. The hazard lights were stuck on and could not be turned off. This left me stranded and in a dangerous situation. After approximately 2-3 minutes, the vehicle was able to restart, but numerous warning lights remained illuminated on the dashboard. I had the vehicle tested with a diagnostic tool at an AutoZone, but no apparent issues were found in the system. Additional Information: This is an ongoing and unresolved safety issue that Honda has failed to address. This electrical problem, which causes the vehicle to shut down unexpectedly, is a significant safety hazard. This issue is in addition to another ongoing problem with the remote start system, which Honda has refused to diagnose and fix. Consequences and Concerns: The unexpected shutdown of the vehicle while in operation is extremely dangerous and could lead to a serious accident. The inability to use hazard lights properly further increases the risk to myself and other drivers. The intermittent nature of the problem makes it difficult to diagnose, but the consistent occurrence poses a serious risk that requires immediate investigation by Honda and the federal safety agency.
The contact owns a 2023 Honda Accord. The contact stated that the vehicle failed to lock while the key fob was not inside the vehicle. Additionally, the contact stated that messages pertaining to the braking system failure, the EPS failure, the Collision Mitigation Braking System failure, and other unknown messages were displayed, with several unknown warning lights illuminated. The vehicle was taken to the dealer to be diagnosed. The vehicle was not yet diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 37,200.
I will be driving down the road and my vehicle will pop up with the brake message and slam by brakes. It does it randomly. It has put my safety in risk multiple times. It has done this on the interstate and thankfully there was no one behind me. I was going 80mph and it dropped me to 30mph in less then 5 seconds. The issue has not been reproduced since it does it randomly. The vehicle has been taken to the dealership many many times. There were no warning symptoms or anything. It just does it very randomly. I had an investigation open with Honda and all they said to do was take it back to the dealership. This car is an issue to public safety. I could very well be in front of someone one day who is not paying attention and there could be a very bad issue. There has been so many times these issues have occurred.
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.
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 .
When driving home the car emergency braked with no cars, debris, or anything else in the road. Car breaked to a full stop from 40mph causing serious whiplash and almost causing an accident.
Rear camera fails when the outside temperature is hot, camera lost color image showing only the image on black & white, bringing the potential loosing of distant perception to the driver due the lack of color and the increase of the shadows on black and white image, I already take the car to Honda dealer and the response was Honda is aware of the problem and they are in the process of investigation due several new vehicles had the same problem.
Vehicle sometimes picks up blacked out or repaved cracks in road as departing the lane. The vehicles steering wheels shakes and vibrates then steers back into what it thinks is the center of the lane. Mind you as I’m already centered. It begins pushing car into on coming traffic and lane. Also the bottom aluminum transmission cover has come loose causing the skid plate or cover to come down on one side. This particular piece has fallen off and was dragging causing sparks. Sometimes the speed limit on the dash reads 65MPH as 85MPH
Cruise control will apply brakes when lane ahead is clear. This happens multiple times per trip, every trip. Automatic emergency braking way too aggressive. Has nearly caused me to be rear ended twice. I try to remember to disable it every drive. I wish I could permanently disable it.
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.
Driving at highway speed (70 MPH) the power assist steering and all of the Honda Sensing suit subsystem totally quit working. The dash had multiple warming lights and dialog box's describing system failures, I continued driving till I could get off of the highway and turned the vehicle off, after about 10 minutes I restarted the vehicle and all systems and steering reset. Drove the vehicle to Lompoc Honda for maintenance diagnostics they found multiple codes but no real cause, the dealership cleared the code per Honda's direction and test drove the vehicle several times. I was told to return if the issue persists.
I have had 2 separate experiences with starting my car and the lights on the dashboard come on. A message comes on with rolling alerts that states the automatic emergency braking, steering assist, lane keeping assist, braking assist, hill hold, adaptive cruise control are all turned off. Additionally regenerative braking was also turned off. I took it to two different Honda dealerships for maintenance. (May 8th, July 20). If you wait 30 mins the alert will disappear. My most recent incidence occurred on Sept 2, I was out grocery shopping and the alerts reappeared while in motion. I was very afraid bc I have never had it come on while in motion. From my second visit July 20th I took it to get looked at and they said that they could not re-create the issue. So both dealerships restored the factory settings. Now this is my third time dealing with this. I took it on July 20th to have them update the system bc it continues to alert when turned off that there is a system update. I had to take the care back twice bc the system update kept alerting. While reading other people's issues I see it is connected to getting the system updated. I have paid a lot of money for this car and it only had 39 miles on it. I see that someone else has had this problem in the past. I travel for work and this is certainly an inconvenience. I want to know how serious is this problem and has other people reported this. See the federal safety agency ID Number: 11533957 for reference. I will be putting my photos on this report to show how the dashboard lights up. In my first visit they thought it had something to do with the electricity or battery as they explained to me, but the problem keeps happening. For the cost of this vehicle someone needs to find out what the issue is and fast. I do not want to have to abandon this care for my safety.
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.
All the lights on my dash came on and the car would not move no faster than 10mph. Took it to the dealership and the mechanic stated that the brake light switch was not properly installed at the factory
I have reported that software cannot be updated on my car. Since my first report my rear seatbelts no longer need to be fastened with children in the car or the seat belt notification of not being fastened does not work. My air conditioner will stop if my infotainment system needs to be adjusted through my phone, and today in the rain my brakes locked up twice. The latter occurrence was coming down 1000 foot downhill in the rain with a car in front and an 18 wheeler behind me
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.
