Description of Incident: 1. Component/System Failure: The engine cooling system and head gasket failed. A certified shop has confirmed coolant intrusion and a failed leak-down test on Cylinder 2. The vehicle is available for inspection upon request. 2. Safety Risk: My safety and the safety of my family and other drivers were put at extreme risk. On March 1, 2026, the vehicle suffered a sudden loss of motive power while traveling at 70 MPH on the freeway. The car dropped to 15 MPH instantly, forcing me to maneuver across active lanes to a narrow shoulder with almost no space. I was nearly hit by high-speed traffic. This has occurred over 8 times since 2023. 3. Confirmation by Service Center: The problem has been reproduced and confirmed by an independent service center On Site Lube Auto & Tire. They utilized a borescope and leak-down test to verify the internal engine failure. 4. Inspections: The vehicle has been inspected by a certified independent technician. I am in the process of notifying the manufacturer (Honda) of these findings for their inspection and accountability. 5. Warning Lamps & Symptoms: Prior to the total power loss, the vehicle displayed engine temperature warnings and "check engine" lights. These symptoms first appeared approximately 8 months after purchase in 2023 and have progressively worsened, leading to the current engine failure. 6. Additional Notes: This failure is identical to issues cited in active class-action lawsuits regarding Honda's engine defects, affecting both standard and Hybrid models. I am communicating via written report/email for documentation and accessibility purposes.

Inadvertent Automatic Emergency Braking
On February 21, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE22003) to assess reports of inadvertent activation of the Collision Mitigation Braking System (CMBS), an automatic emergency braking (AEB) system, in model year 2017-2019 Honda CR-V and 2018-2019 Honda Accord vehicles. The reports allege that activation of the AEB system occurs while driving with no apparent obstruction in the vehicle's forward path, resulting in sudden vehicle deceleration. Honda indicated that they were aware of a total of X,XXX reports that may relate to the alleged defect. Honda provided analysis of the alleged defect and alleges that some customers possibly had an inadequate understanding of the CMBS and its limitations.  However, many consumer complaints allege that Honda dealerships were unable to reproduce the condition or state that they were informed that this is considered normal CMBS operation. To date, ODI has received a total of 1,294 consumer complaints of inadvertent activation of CMBS in 2017-2022 Honda CR-V and 2018-2022 Honda Accord vehicles. A total of 31 complaints alleged a crash and 50 alleged an injury. The Total column in the Failure Report Summary removes duplicate reports and shows the total number of reports with unique VINs from all Manufacturer, ODI, and EWR data sources. In some cases, there were multiple reports associated with a particular vehicle in which recurring failures were alleged. In total, there were X,XXX reports, 93 injury incidents and 47 crashes involving vehicles with unique VINs that may relate to the alleged defect. PE22-003 has been upgraded to an Engineering Analysis to further assess the scope, frequency, and potential safety related consequences of the inadvertent AEB activations. The scope has been expanded to include assessment of model year 2020-2022 Honda CR-V and Accord vehicles.

What 2019 Honda Accord Hybrid owners say
Most recent owner complaints, unedited.
While traveling at approximately 55 mph yesterday, in daylight, with no other cars in front, back, or to the side of our car, it radically braked on its own. The collision mitigation system warning light has frequently flashed on the dashboard since we bought the car new in 2019 but never did it apply the brakes on its own. Dealerships over the years have told us "this just happens", and offered no fix for the false positive alerts. This is a dangerous situation which could result in an accident or even death of occupants if not resolved by Honda. I spoke with several dealerships since the phantom braking event and they tell me they hear this complaint often. Being an intermittent situation, it is extremely difficult to diagnose and resolve. Something needs to be done.
All of sudden, no incident, no accident, a lot of things were disabled such as Adaptive Cruise Control , Forward Collision Warning , Lane Departure Warning and more while I was out of town (long range highway travel). When I went to Honda dealership, they blamed a few things and fixed them (expensive), then they said that the front camera needed a calibration. It was expensive. After that aiming correction, everything works fine. The camera was NOT broken. It just needed recalibration, and it costed about a thousand dollars. I would say it was caused by the poor design, which is Honda's fault. I googled this issue and found a lot of Honda owners had same issued and charged 1K ~2K for it. I will report it separately, but my Honda Odyssey has the exactly same issue now. I have 2 Honda cars, and both of them have the same issue. I strongly suggest that Honda should recall their front camera and they should reimburse the expense we already paid for it.
I was driving on a city street at about 30mph. There was no one in front of me or behind me. Nothing in the road. The orange rectangular brake light came on for no reason, kept flashing and it felt as if the brakes were automatically being pumped, slowing the car down to a compete stop. In addition, I had no control of the steering. It was very dangerous situation which could have resulted in accident or injury.
Forward collision warning stopped working after a system upgrade on my 2019 Honda Accord hybrid. I activate the forward support and immediately it turns off. This is a safety issue. The system assist in breaking in time to maintain car distance and avoid a collision. Contacted Honda. I was told to take it to service at my cost.
Suddenly I get warnings of failure of adaptive cruise control, failure of braking, stearing and forward collision warning failure. It goes away if I drive my vehicle for few miles but then suddenly appears again. No one seems to know what is the issue. I tried to reset setting multiple times, checked system updates and checked battery etc, asked to check if there are any faulty codes but no one seem to know what is going on. It keeps happening every day
I have was called steering sticking in my steering wheel when I’m driving and it stuck straight and I have to turn it a little bit. I have to kinda yank it just a tad bit because the steering is sticking is an issue with other Hondas. I’m having it also.
The Lane Departure Warning. Auto Dimming Headlights,, and traffic sign Recognition system stopped working at about 40000 miles. The dealer says they can't fix it. Also, my windshield, like so many others I've read about, spontaneously cracked while parked, on a day with moderate temperature and no hail. The camera was realigned. Still, the 3 sensing aids above still don't work. Uncertain about exact date
On multiple occasion my vehicle will brake unexpectedly with no object in the road or surrounding my car. It has done it at freeway speeds as well as driving through parking lots. It often will sense construction repairs on the road and think I am departing the lane again slamming on the brakes (on the freeway) I have luckily avoided accidents but have had numerous close calls.
07/28/2023 - Car showed many brake system errors: electric parking brake, vehicle stability, adaptive cruise control, etc. Took to Heritage Honda, Bel Air, MD, and got error code diagnosis of PI20-00, brake system/pedal simulator failure. Heritage "reflashed" pedal simulator and cleared code. Told OK to drive but if brake system errors showed up again, pull over to side of road and have car towed. Drove 20+ miles home. 07/29/2023 - Car again showed brake system errors as on 07/28. Husband and I drove car around our development and there were no brakes, even after husband pumping and pushing down on brake pedal very hard. 07/31/2023 - Flat bed towed car to Martin Honda, Newark, DE and got same error code. Paid to replace brake pedal simulator, PN 01469-TWA-A56. Issue is that brake system did not fail safely, because failure of pedal simulator left me with no brakes. Requested Honda pay entire Martin Honda invoice but Honda paid $1400 of repair. Have since requested that Honda pay remaining $1000 that I paid, plus diagnostic fee for Heritage Honda, and towing charge.
