The cylinder head gasket on this vehicle has failed, causing engine coolant to leak into the combustion chambers (coolant intrusion). This has resulted in a recurring and dangerous loss of motive power that has put my safety and the safety of other motorists at risk on multiple occasions. Specifically, the vehicle has repeatedly entered "Limp Mode" while in active traffic, causing a sudden, drastic loss of acceleration that left me unable to maintain the flow of traffic or safely maneuver. This component failure is available for inspection upon request. The problem has been officially confirmed by Holman Honda of Fort Lauderdale, where technicians diagnosed the blown head gasket and confirmed the presence of coolant in the cylinders. The manufacturer's authorized dealership has inspected the vehicle and provided a formal repair estimate. Prior to the multiple "Limp Mode" failures, the vehicle exhibited clear warning symptoms starting in late 2025, including violent engine stuttering and a "shimmering" vibration during cold starts. Additionally, a distinct "gurgling" or bubbling sound was audible behind the dashboard, indicating combustion gases displacing coolant. During the actual failure events, the dashboard displayed a "Christmas Tree" effect of warning lamps, including "Emissions System Problem," "Brake System," and "Power Steering System" alerts, which disabled critical safety and driver-assist features while the vehicle was in motion. This persistent design defect has created a high risk for rear-end collisions and total engine seizure.

Over the past several years, there have been multiple instances where I or my wife are driving on the highway and the engine light comes on or starts flashing, and I am unable to go faster than 50 miles an hour, and the engine itself feels to be underpowered. We have taken it to the dealership for repair at least five times over the past five years and in each case they have attempted to do a repair and said the issue has been resolved, but the issue continue. At at least one of those visits, they have diagnosed the issue as an engine misfire issue. The issue has intensified from the initial symptoms, (which were as I described, but resolved by turning the car off, waiting 30 seconds to a minute and then turning the car on again) to how it is now: in addition to the check engine light, every other light and warning system has gone off when driving on the highway and the engine was unable to go faster than 40 miles an hour, and it does not resolve by restarting the car. The dealership and Honda America’s main phone line have as of yet been unable to give me a clear answer as to why this is happening or whether it can be fixed. A sudden drop in speed and power on the highway as we have experienced many times over the last five years is inherently extremely dangerous.

I purchased this 2018 Honda Accord Sport brand new from the dealership, relying on Honda’s longstanding reputation for reliability and longevity. At approximately 120,000 miles, the vehicle suffered a blown head gasket during normal driving conditions. The vehicle has been properly maintained according to Honda’s recommended schedule. I have already opened a claim with Honda corporate regarding this issue and am currently awaiting their response. Despite proper maintenance, this catastrophic engine failure occurred, suggesting a design or manufacturing defect rather than misuse. This issue presents both a safety concern and a substantial financial burden, as I am a single mother of four who depends on this vehicle for daily transportation. Based on reports from other owners, this appears to be a widespread defect affecting 10th-generation Honda Accords with the 1.5L turbo engine, which I respectfully request NHTSA investigate.

After I took my car in for a fuel pump recall, it caused one of my injectors to be bad which will be 3000 dollars fix out of my pocket. this happened a few months after I took my car to the dealership, and it was doing fine before taken to the dealership for the recall. there are many other owners who reported they experienced the same thing, with all the dash lights came on but couldn’t find the exact cause until they replace their fuel injectors. First, all the alarms appeared, even the engine light was on but they would all go away after a few days. It had been on and off randomly for the past 4 months. the car is still driving fine but the alarms will pop up and stay for a few weeks to a month. It would randomly not letting me accelerate and slow me down, which if i was driving on the highway all the way in the left with traffic, that would cause a traffic jam and eventually an accident with other drivers.

The first time was at 93,000 miles where my car started to surge and went into limp mode but once I shut the car off and turned it back on everything went away and the car was fine. It did happen a couple more times, but as soon as I would shut the car off and turn it back on the code was cleared and by the time I got it to a mechanic there was no known code.This last time was at 220,000 miles I was just entering the freeway and once on the freeway, my car started to power surge really bad jolting me back-and-forth back-and-forth. This did not let me continue to finish reaching my highway rate of speed with cars coming up fast behind me nearly hitting me. Car continued to surge, and then went into limp mode and I had to pull over on the side of the freeway. I brought my car into Honda of San Bruno, California. They informed me after inspection that I had a cylinder three misfire due to a bad head gasket. They are receiving 3 to 4 of these a day and is a huge problem. I later found out that there’s a class action lawsuit for this head gasket failure that put me in danger and now has my car sitting in front of my house unable to drive.

Transmission keeps malfunctioning from 1-2 and 2-3 gear shifts. Mainly prominent on the 2-3 gear shift having issues. Severe transmission jerk and sometimes slams into the next gear. This has been happening since I bought the car at 52k miles and it is currently at 62k miles. It can be available for inspection upon request. It also jerks on downshift. The transmission fluid has been drained and filled with Honda genuine atf 2.0 but the issue still persists after the service. The vehicle has not been inspected by the manufacturer. It has put my safety at risk because in low speed traffic my speed is unpredictable and I am worried of hitting a car in front of me. It is also an issue for vehicles behind me as well because the vehicle cannot find the gear and doesn't accelerate properly. When it slams into the next gear it seems to be a severe safety hazard for me and my passengers.

Headgasket seems to be forming a leak. Checked coolant today, zero leaks on coolant system but coolant was extremely low. It is sad to see that Honda has become so unreliable.

The vehicle experienced a catastrophic engine malfunction resulting in a no-start condition. The vehicle is currently inoperable and is available for inspection upon request. The engine failure caused the vehicle to lose power and become unreliable, creating a risk of breakdown while driving, which could have resulted in being stranded in traffic or an unsafe location and posed a risk to my personal safety and the safety of others. Yes. An independent repair facility confirmed the vehicle would not start and diagnosed the engine as failed. The vehicle was subsequently towed to another facility, where the condition was again documented. The vehicle has been inspected by independent repair facilities. The extended warranty company, Route 66, reviewed the claim and denied coverage based on their assessment. No inspection by the manufacturer or law enforcement has occurred. Prior to the failure, the vehicle exhibited warning indicators and operational issues, including overheating symptoms. These issues worsened over time and ultimately resulted in complete engine failure and a no-start condition.

The vehicle experienced a rough idle and white smoke blowing out the exhaust on a cold startup. It did have coolant loss over a period of time with no visible leaks. I waited until I got a check engine code that revealed a misfire in cylinder 4. Upon further diagnostic testing it was revealed that the head gasket was blown between cylinders 3 and 4. I paid for the repair out of pocket only to see that this is a very common issue with the 1.5 turbo engine.

When I was accelerating the vehicle on 12/21/2025, a flashing check engine light came on, and the car started driving very roughly immediately, with an intense vibration. I noticed a lack of engine power, but the hybrid motor and battery kept me going for roughly 1 mile until they were depleted, after which I was unable to accelerate the vehicle. At that time, the car continued to decelerate, no matter how much I depressed the accelerator. I was able to safely pull over and turn the car off. I let it sit for one minute before turning it on again, at which point it behaved normally. I drove very cautiously to my destination, making sure to accelerate very gradually. This sudden lack of power put myself and others on the road at risk, as it was very sudden with no prior symptoms/warning lights, and I had no recourse besides pulling over as soon as possible. Over the next few days, I researched the problem online, and owners of Honda Accords from that generation (10th generation, model years 2018-2022) reported head gasket failure on all engines Honda offered the 10th generation Accord, including the 1.5 turbo, 2.0 turbo, and 2.0 hybrid engines. This problem is also reported on a slew of other Honda vehicles from roughly that time period. I brought it to Motor Werks Honda in Barrington, IL on 12/24/2025. After they completed their analysis, they determined it was a failed headgasket.

The A/C condenser on my Honda failed and leaked out all of the refrigerant, which subsequently caused the A/C compressor and related components to fail. This issue is well‑documented, and Honda has issued an extended warranty specifically for the condenser due to its known defect. My vehicle was inspected by an authorized Honda dealership, and they confirmed that the condenser failed and that the resulting loss of refrigerant caused the compressor to generate metal shavings. These metal particles can circulate through the HVAC system, potentially entering the cabin and posing a health risk to the driver and passengers. Despite the clear causal relationship and the dealership’s findings, Honda is refusing to replace the failed compressor and associated components, even though the failure originated from a part they acknowledge as defective and have extended warranty coverage for. There were no warning lights, messages, or symptoms prior to the failure. The A/C system stopped functioning without any advance indication, leaving me without proper ventilation and climate control. This defect raises both mechanical reliability concerns and potential health and safety risks due to metal contamination within the HVAC system. I am requesting that NHTSA investigate this issue further, as Honda’s refusal to cover the full scope of damage caused by their known defective condenser leaves consumers exposed to unnecessary safety hazards and significant repair costs.

Blown head gasket at around 91,500 miles even though car have been kept up with oil change around 5,000k mile. It is currently in the mechanic shop as of 1/12/2025 awaiting repairs (parts are being order as we speak). So, probably can't have it inspected if requested unless it is soon. The random/early head gasket getting blown with not such high miles would have been devasting if I was driving on the highway. Since, it would cause the engine to over heat as the coolant is leaking into the engine piston and some case could cause lost of power on the highway. This problem seem to be quite common or expected as talking to the dealer and they were aware that a portion of these 1.5l turbo engine head gasket are getting blown. The vehicle or component has been inspected by an independent service center. I got misfire detected on cylinder 3 on 12/17/2025. I replace the sparks plug and it ran fine till 1/10/2026 when all of a sudden I can see the temperature gauge climbing. I stop driving the car that day on 1/10/2026. I check the coolant overflow reservoir on 1/11/2026 and found it strange that it was almost empty. I decide to take it to the mechanic on 1/12/2026 because I didn't see leaks anywhere and that was when they found the head gasket has failed and was slowly dripping coolant into the cylinder.
