What owners say
Unknown cause - Heavy Traffic I get all warning lights (idiot) come on. No performance loss but every advisory and caution is illuminated. Tested battery 550amps and regulator was putting out 14 volts so all seemed fine. Check battery terminals and connections, all good. After two days lights go away and everything works fine. When lights and advisory are on, no cruise control, TMPS, lane departure, assisted steering, and anything else in the caution light display doesn't work. Good thing all other aspects of the car work fine. Unable to determine the issue with Why this happens. Seen on line others have had this same issue.
I am submitting this complaint regarding an ongoing safety concern with my 2021 Honda Accord. Multiple lights indicate engine system problems which includes, check engine light, car jerks at acceleration, seat sensor recall. I took my vehicle to multiple shops including the Honda Dealership. However, they were unsuccessful to identify the cause. Multiple problems such as Turbo, belt, fuel system problem constantly comes up. I have attempted to take my vehicle for the recall, which was scheduled, however after waiting 4hrs, the dealership stated they did not have the parts. I am concerned about the potential risk to myself, my daughter and my passengers and believe these issues warrant further investigation to help prevent possible accident or injury.
Computer BCM module malfunction while driving. All warning light went off like Christmas tree.
The contact owns a 2020 Honda Accord. The contact stated that while driving at 35 MPH, several warning lights illuminated. The vehicle was taken to the dealer, where the battery was replaced; however, the failure recurred. The vehicle was taken to three independent mechanics, where the failure was confirmed, and the battery was replaced; however, the failure persisted. The contact stated that the battery was replaced four times within three and a half years. The contact stated that the warning lights turned off temporarily upon replacing the battery. The contact stated that the failure was a common issue.
On 09/18/2026, at 103,000 miles, my vehicle suffered a dangerous powertrain failure where numerous dashboard warning lights illuminated and the car suddenly dropped into "Limp Mode" with an immediate loss of acceleration while in active traffic. I took the vehicle to a certified Honda dealership, where technicians officially diagnosed the issue as a "Fuel System Too Rich" condition (Diagnostic Trouble Code P0172). The dealership confirmed that the factory-installed direct fuel injectors are failing prematurely and leaking raw fuel into the engine cylinders. This manufacturing defect causes severe engine oil dilution, where gasoline contaminates the oil pan, creating an immediate stalling hazard and an extreme risk of a high-speed rear-end collision. Online owner forums and dedicated global social media groups indicate that thousands of other 10th-generation Accord owners are experiencing this identical safety defect. Honda corporate has formally denied goodwill assistance, treating this severe engineering flaw as standard wear and tear. The vehicle and failed components are fully available for inspection upon federal request.
I am reporting multiple recurring safety concerns involving my 2025 Honda Accord, including apparent electronic parking brake malfunctions, Auto Brake Hold failures, electrical system warnings, violent engine restarts, and a possible battery or charging-system defect. While stopped in traffic, particularly when the Auto Idle Stop system shuts off and restarts the engine, my vehicle sometimes experiences an unusually violent shaking or jerking motion. The restart can feel like a sudden, forceful kick. During these episodes, the electronic parking brake appears to engage unexpectedly without my manually activating it. Multiple dashboard warning lights and messages intermittently illuminate, including Brake System Problem, Brake Hold warnings, and other braking-related alerts. I have also experienced braking-related warnings or abnormal operation when traveling on inclines. The warning indicators sometimes disappear afterward, but the problems recur. I am concerned that these malfunctions could interfere with normal braking, acceleration, or vehicle control, particularly in traffic or on hills, creating a collision risk. Additionally, an AAA roadside assistance technician advised me that my vehicle’s battery appeared to be leaking fluid and needed replacement. A subsequent battery check at an auto parts store did not identify the same concern. I have repeatedly noticed a strong rotten-egg, sulfur, or sewage-like odor near the front of the vehicle and entering the passenger compartment through the air-conditioning vents. Another occupant independently noticed the foul odor. I am concerned about possible battery overheating, charging-system malfunction, electrical faults, and potentially hazardous fumes entering the cabin. The exact cause of these recurring problems has not been determined. I am requesting that these braking, electrical, engine restart, and ventilation-related safety concerns be investigated. The vehicle is available for inspection upon request.
The contact owns a 2019 Honda Accord. The contact stated that while driving at highway speeds, the vehicle suddenly lost power and decelerated. The contact stated that several warning lights were illuminated and the vehicle decelerated quickly. The contact feared for her safety because of the sudden deceleration on a busy highway. The contact was able to guide the vehicle safely onto the shoulder of the road. The contact stated that prior to the failure, the vehicle had received several recall repairs including a BCM reprogramming, software updates, and fuel pump recall repair. The vehicle was towed to a local dealer and the vehicle remained pending a diagnostic test. The failure mileage was 62,590.
The car was rough upon idle one day and all the lights came on and systems went down I was bout to drive to a place where the code was read that’s when I first discovered this was a known issue which this model. Head gaket
While driving my Honda on a highway at approximately 65 mph after rainfall, I experienced a serious and potentially life-threatening safety failure. Without warning, the steering wheel suddenly became locked/restricted, making it extremely difficult to control the vehicle. At the same time, numerous warning lights and safety-system warnings appeared, including: - Brake system warning - Electric Power Steering (EPS) warning - Vehicle Stability Assist warning - Hill Start Assist warning - Adaptive Cruise Control warning - Lane Keeping Assist warning - Collision Mitigation Braking System warning - Road Departure Mitigation warning This incident occurred while I was traveling approximately 65 mph on the highway and nearly caused me to lose control and crash. The sudden loss/restriction of steering control combined with the simultaneous failure or disabling of multiple driver-assistance and safety systems created an extremely dangerous situation. The fact that this occurred after driving in rainy/wet conditions is also concerning. I have researched this issue online and found numerous reports from other Honda owners describing similar warning lights, steering/electric power steering problems, and multiple safety-system failures, particularly involving Honda Accord vehicles. I am extremely concerned that this may represent a recurring safety-related defect rather than an isolated incident. A steering system that can suddenly become locked or severely restricted while a vehicle is traveling at highway speed presents a serious risk of a crash, injury, or loss of life. I respectfully request that the federal safety agency investigate this issue, review complaints involving similar Honda vehicles, and determine whether there is a common defect involving the electric power steering system, electrical system, water intrusion, or communication between the vehicle's safety-control modules. This problem needs to be investigated before someone is seriously injured or killed.Best regards.
