The contact owns a 2019 Honda Accord. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated. The vehicle lost motive power and went into LIMP Mode, and the steering wheel seized. The vehicle was taken to the local dealer, and the failure was initially misdiagnosed. The vehicle was then towed to the dealer a second time, and the dealer discovered that the battery and fuel injectors needed to be replaced. The vehicle was repaired, but the failure recurred. The vehicle was later diagnosed, and it was determined that a gasket had failed. The vehicle was repaired, but the failure persisted. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 72,281.

Vehicle: 2019 Honda Accord Sport 1.5L VIN: [XXX] Mileage: Approximately 122,497 My vehicle experienced a cylinder head gasket failure accompanied by coolant intrusion into the engine cylinders, injector-related issues, fuel trim failures, and cylinder misfires as diagnosed by an authorized Honda dealership. Prior to diagnosis, the vehicle experienced engine performance concerns associated with the misfire condition. The dealership documented historical misfire events and coolant intrusion into the combustion chambers. I am submitting this complaint because I am concerned that injector-related issues, engine misfires, coolant intrusion, and cylinder head gasket failures may represent a recurring condition affecting similarly equipped vehicles. Engine misfires and coolant intrusion can potentially result in reduced engine performance, loss of power, unexpected vehicle behavior, or engine failure while the vehicle is being operated. I request that the federal safety agency review this issue and determine whether a broader investigation is warranted.

My car started getting hot, began to overheat. I was on my way home on freeway. Second lane from slow lane. My car began to loose power, I could no longer excelerate. There was a big rig coming up behind me he was not slowing down as he got closer began honking I was trying to flag him that I could not move, as I was trying it started to go like 5 miles per hour where i began slowly to get over, cars in the other lane slowed down. Big rig went around me and avoided any collision. Thank God. I slowly made my way home on the streets with heater blasting. I towed my car to the dealer. I was told, my head gasket needed to be replaced, more than likely I would need a knew engine. Dealership said it was because when taken my car in for service I did not bring to the dealership. Cashier told me that there have been several incidents as mine.To my surprise I googled 2019 Honda Accord engine, and there were many with the same issue same car same year. Yet no recalls! I was lucky not to have been killed or have caused a multiple car collision. Are we waiting for someone to be killed to recall these engines. I missed several days of work, borrowed cars and rented a car to get back and forth to work not to mention the tramatic experience of a big rig coming at you honking on a FREEWAY. A week prior to this incident, my lights on the dashboard came on. I did call the dealership to set up an appointment. At that point they were no signs of overheating. I have taken my care in faithfully for oil changes where all fluids are checked, i was not told not once that any fluids were ever low, last visit was approx 5 months ago. I have called to have them send me all receipts. However in hindsight I do not need theses records as it has been proven by other people they have had the same experience. We are not talking about a faulty air conditioner we are speaking of an engine, in my case power failure. In the even records of oil changes and dealership diagnosis is required. I can email.

The vehicle, a 2019 Honda Accord, experienced a catastrophic engine failure (blown head gasket) and entered "Limp Mode" after being operated for approximately 18 months with an unaddressed, high-priority federal safety recall (the federal safety agency 23V‑858). The vehicle currently displays DTCs P0100, P0113, and P023D, which indicate severe air/fuel metering and boost pressure correlation failures. Primary Cause: Consequential Thermal Stress The primary cause is likely thermal degradation of the head gasket resulting from a prolonged "lean-burn" condition. Recall Defect: The recalled fuel pump impeller is known to deform, restricting fuel flow. Lean Condition: A restricted fuel supply causes the engine to run "lean" (too much air, not enough fuel). Lean combustion is significantly hotter than normal combustion. Heat Accumulation: Over 1.5 years of operation with this restricted flow, the engine experienced repeated, excessive thermal cycles that compromised the structural integrity of the head gasket. Limp Mode Trigger: The stored codes (P0100/P0113) show the ECU was struggling to compensate for the erratic fuel/air environment created by the failing pump. Secondary Assessment (The Dealer's Claim): The Service Advisor (Paul) has alleged that aftermarket components and a missing turbo gasket caused the failure. Assessment: While aftermarket parts increase scrutiny, a missing external turbo gasket typically causes an exhaust leak or loss of boost, not an internal head gasket failure. Contradiction: The dealer must provide empirical proof that these parts caused the failure, whereas the federal safety agency recall is a pre-documented, manufacturer-admitted defect known to cause the exact stalling and "limp mode" symptoms the vehicle is currently exhibiting. Conclusion: The most probable cause is manufacturer negligence. By failing to provide a remedy part for 18 months, the manufacturer forced the vehicle to operate under a documented defect that creates the exact high-heat conditions required to cau

I own a 2019 Honda Accord equipped with the 1.5L turbocharged engine. At approximately [142,000] miles, the vehicle began overheating and losing coolant with no visible external leaks. A Honda dealership diagnosed the vehicle with a blown head gasket caused by coolant intrusion into the engine. The repair cost quoted was several thousand dollars. Honda has denied goodwill assistance dates DEC 16, 2025 at 1:35PM, despite documented maintenance and the widespread nature of this issue in Honda 1.5L turbo engines. This failure occurred under normal driving conditions and presents a safety concern due to sudden overheating, loss of engine power, and potential engine failure while driving. I believe this is a known design defect affecting multiple Honda vehicles, and Honda has failed to properly disclose or remedy the issue.

Vehicle Information: Make/Model/Year: 2019 Honda Accord VIN: [XXX] Mileage at time of issue: ~70,000 miles Engine: 1.5L Turbo (if different, update before submitting) Dealership: Capitol Honda San Jose, California Complaint Summary: Engine misfire, rough running, and head gasket failure allowing coolant into cylinders. Details of the Problem: At around 70,000 miles, my 2019 Honda Accord began running rough and misfiring. Our independent mechanic scanned the vehicle and found failure codes for cylinders 2 and 3. The spark plugs and ignition coils were replaced, but the car continued to run poorly and the misfires persisted. We then took the vehicle to Capitol Honda in San Jose, CA. The dealership performed a diagnostic inspection and a borescope test, confirming coolant intrusion in the combustion chambers. They diagnosed the vehicle with a blown head gasket, noting visible coolant in cylinders 2 and 3. This car has been carefully maintained, never overheated, and serviced on schedule. Head gasket failure at this relatively low mileage is abnormal and appears consistent with defects reported by other Honda owners involving turbocharged 1.5L engines. This condition can cause rough idling, loss of power, and potential engine stalling, creating a safety risk while driving. Repair costs are significant and may indicate a systemic defect in this engine design. Requested Action: Please investigate head gasket and coolant intrusion failures in 2018–2022 Honda Accord models, especially those with the 1.5L turbo engine, as this issue appears to be increasingly common and poses a risk of sudden engine failure.

On Dec of 2022 I expereienced my first encounter with the recall and my engine was affected. I was on a busy Highway when the car made some weird noises and then stalled. When I took the car to the mechanic, he stated I needed a new engine. I couldnt understand why however I needed my car and had to get it fixed. Months later, my car again, leaves me on the side of a congested street, because it stalled. This time, im told its the fuel pump. For two months every week, I am at the mechanic because it ends up that my car has two fuel pumps and both went bad. I end up hearing about the fuel pump recall after I spent $8600 on getting my car fixed. I am imploring for full reimbursment. This matter left me on sides of roads many a times and need assistance with getting my monies back.

My car was initially at Performance Honda due to engine failure on June 24, 2022. They called on July 20, 2022 and confirmed that my car engine was repaired and I picked it up on July 20, 2022. Then on July 23, 2022, I incurred the same engine failures as noted by the warning and error lights on my display panel. The car started slowing down while I was on the expressway creating a safety hazard but I was able to drive it to Performance Honda. The manager explained that the car needed a turbo and they had to asked Honda to approve the purchase to install it into my car. I dont know if the turbo is new or used or even under warranty but Performance Honda contacted me on August 8 and said again the engine was repaired. I've read where there are other owners experiencing similar issues. My car was still within warranty of my purchase date July 17, 2019 and the repairs were made under the warranty but I still incurred rental car expenses that have not been reimbursed to date.

Rodent chewed the soy based wiring harness in the engine bay causing various fault codes: electric power steering system problem, brake system problem brake performance may be reduced, tire pressure monitor system problem. Dealer removed intake manifold, throttle body, remove fuel rail and #3 injector. Repair connector wiring harness to #3 injector. Replace engine wiring harness. After the harness is replaced. There are still warning lights that will not clear. Pull engine cover and lower bumper cover at front/note that there is rodent damage on two other wiring harnesses removed and replaced front bumper wiring harness and engine to body wiring harness. Went into system and cleared all codes. Rechecked and steering needed to be initialized through the vsa system. Drove the vehicles for a few days and all the problems re-occurred again. Honda has a rodent repellent tape part # 4019-2317. However, service advisor did not have any knowledge that the service department sold this tape. This proves honda is aware of the rodent issue of eating wiring harness.
