I took my car in because the electric parking brake warning appeared while driving. I also looked it up and saw many others were having this issue. So basically Honda charged me for something that’s an ongoing Honda issue and passed it off as a glitch and cleared the codes. Clearly Honda needs to recall the 2023 accord because this isn’t safe and clearing the code isn’t taking care of the problem. Furthermore charging me for diagnosing this is completely wrong knowing this is not a problem only I am having. Honda needs a recall before there are serious accidents.

It is my understanding Honda issued a extended warranty on the air conditioning condenser for its Accord models from 2018-2022. I have a 2023 Accord and the exact same issue has happened on my car. Similar to the earlier problems with fuel pumps where a partial recall was extended to the same model built in later years, I am suggesting Honda needs to repeat the extended warranty to include 2023 models. I am bringing this issue to your attention in case others are having the same experience.

To Whom It May Concern, My 2023 Honda Accord (VIN: <Fill in red: VIN [XXX] >) has been disabled since January 27, 2026 due to a fuel system failure. The dealership falsely claimed diesel contamination, which I deny. Despite escalation to Honda executives and NJ Lemon Law action, the vehicle remains unsafe and unusable. Attached is documentation supporting my complaint (Master PDF: Camardo_Honda_Accord_Escalation.pdf). I request your immediate review and assistance to resolve this safety issue. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving down the freeway and all of a sudden there was a spontaneous, loud-bang, and explosion-like shattering of my moonroof/sunroof. I didn't know what happened initially but heard glass shards sliding around the roof. I slid the cover slightly open and could see the shattered glass. I drove home and discovered a hole in the glass. Im attaching pictures of what I saw. I got home and searched online to see if anyone else has experienced this and found several articles referencing 2023 Honda Accord's and this issue. Including some class action law suits against Honda.

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 NHTSA.

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.

I went to put windshield washer fluid into my car. When I opened the hood, I saw that the under hood insulation was gone (Burt away). We just had a snow storm and it happen to be heavy wet snow. I always turn on the car from my house (auto start). The heavy snow forced the hood to touch the engine and because it did not have a cover, destoyed the insulation. I went to Honda and showed the service manager the picture. He said I would have to pay to replace the under hood insulation, that does not seem right.

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

The Infotainment System linked pixel 6 phone freezes. The icons for selecting navigation or other feature freezes. The car has been taken to the dealership twice. Unfortunately, the issue still persists. To resolve, the phone needs to be disconnected and reconnected multiple times for Android Auto icons to work properly. This can cause issues and risk when driving and need to change navigation icons and directions.

The Honda Accord LX is equipped with a seven inch audio infotainment screen that does not detect nor capable of having wifi. The car's computer will update through Bluetooth and/or tethering to my phone. After I set up my hondalink and free att wifi(which wifi is on my phone), I went to Honda dealer I bought from and another local technician to speak to them about my phone tethered settings being on no file transfer. At both locations I was told my car does not update through my phone, they looked for a wifi connection in my car, and then asked to see my phone. I thought a recent update had made my engine go to 4rpms without switching gears. I was told where I bought it at that this was not on my cars computer and it did not happen. I have contacted Honda Corp to be told the same that the car does not update through my phone. Hondalink has a locator and engine updates were applied to my car at 8pm on Friday night in my driveway. Bluetooth does not have enough strength to install engine updates.
