2023 HONDA ACCORD Service Brakes Problems

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)

While coming to a stop on a slight incline, the brakes failed to stop the car, brakes were applied and initially slowed the car but when the slight incline was reached the brakes would not engage and the idle of the car move it forward and still the brakes would not engage. I had to put the car into neutral then park to stop. After the incident the brakes seemed to work fine. Nonetheless this is a major issue. There were no warning lights or any indication that something was malfunctioning. There were no indications after the incident either that anything malfunctioned. I will be taking the car to the dealer ASAP to have checked. We lightly tapped a truck that was in front of us on the slight incline - no obvious damage to either vehicle ( need to verify in daylight) - no injuries to anyone in the incident. If we were traveling faster there could have been serious injury or if there was a pedestrian there could have been serious injury.

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.

While I was driving down the road with my foot on the gas pedal, without any notice whatsoever, my brakes began to jitter/shake and my steering wheel got stuck/tight and would not move. At this point, my car immediately makes a complete stop in the middle of the road and warning lamps appear such as; brake system problem, engine light, etc. I immediately turned on my hazard lights so cars behind me would go around me. Luckily, I was close to a curb and tugged on my stiff steering wheel and managed to park my car alongside the curb on the street. I called the Honda Dealership and they said my car was unsafe to drive and needed to be repaired. I immediately took my car to the Honda Dealership to get repaired. This malfunction could have caused an accident putting myself and others safety at risk as my car made an immediate complete stop on it's own and my steering wheel got stiff/hard to move making it hard to steer. There were NO warning lamps, messages or other symptoms of the problem PRIOR to the failure.

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.

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.

My car makes a weird sound when it gets to a full stop. The dealerships identified the issue but need help fixing it. I and the dealership have contacted Hoda customer service, but they are not willing to fix the problem. This may be a safety threat. I have 3 technician report backing the same and attaching the last one only. No fix done so far.

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 NHTSA 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.

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
