Owner reports
Selected complaints filed with NHTSA by 2023 Honda Accord owners, lightly cleaned up (personal details are redacted by NHTSA).
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. …
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 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.
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. …
Describe the Safety Issue: My 2023 Honda Accord (VIN: [VIN]) 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. …
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. …
Description: This is my second NHTSA complaint regarding unprompted automatic emergency braking in this vehicle. While driving at normal speed on [redacted], with no obstacle, pedestrian, or vehicle ahead, the vehicle's forward collision system activated without warning - audible alert sounded followed by the vehicle automatically applying hard braking and coming to an abrupt stop in the roadway. There was no obstruction, stopped traffic, or hazard present to justify the activation. I had 4 passengers in the vehicle at the time, including two children. The vehicle came to a sudden, forceful stop, creating a risk of rear-end collision from following traffic and a jolt risk to occupants. This is a recurring defect - I filed a prior NHTSA complaint for a similar unprompted braking event [reference no-[redacted] ] that resulted in a shoulder/neck injury to me as well as headache. …
I own a 2023 Honda Accord Touring Hybrid. At approximately 42,000 miles, all of the warning lights illuminated while driving. The warnings included Adaptive Cruise Control, Forward Collision Warning, Lane Departure Warning, Blind Spot Warning, Parking Collision Warning, and multiple other system alerts. At the same time, I experienced a loss of electric power steering assist, increased steering resistance, and clicking/popping noises coming from the steering rack. The Honda dealer diagnosed the vehicle with a failed Electric Power Steering (EPS) steering rack and quoted nearly $5,000 for the repair. A critical steering component should not fail at such low mileage. This is a serious safety concern because the failure affects the driver's ability to safely control the vehicle. …
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 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.
