The head gasket is leaking. Yes, the dealer reproduced and diagnosed the problem. There were no lights on the dash. It is available for inspection if needed.

-?? Head gasket -?? None of the safety features work when there is a head gasket issue. Power steering is reduced as well as break performance -?? Confirmed by Honda dealership with a Boroscope -?? Honda -?? No warning, Honda at first thought it would be fixed by fixing the factory recalls. Light went away prior to taking it in and then looked in to it 2 weeks later and diagnosed head gasket failure

I am writing to report a serious mechanical issue with my 2018 Honda Accord 2.0T that I believe may constitute a design or manufacturing defect with potential safety implications. At approximately 112,000 miles, the engine in my vehicle suffered a blown head gasket, which my mechanic determined was caused by a stretched timing chain. This failure followed roughly nine months of unexplained coolant consumption, during which time no visible leaks were detected. In addition to the coolant loss, the vehicle experienced two separate instances of entering limp mode while driving, creating a significant safety risk due to sudden loss of power. Furthermore, during the winter months, I repeatedly lost cabin heat, suggesting early signs of internal engine issues related to coolant circulation or combustion gas intrusion. These symptoms point to a progressive failure that was not addressed by any recall or Technical Service Bulletin (TSB) during my ownership. Given the growing number of reports from other 2.0T Accord owners experiencing similar issues with premature timing chain wear and associated engine damage, I believe this may be a systemic issue that warrants investigation by NHTSA. A stretched timing chain causing catastrophic engine damage can easily lead to unexpected stalling, limp mode, or loss of control in certain conditions -?" all of which raise concerns about vehicle safety and reliability.

I purchased this 2018 Honda Accord that has had no major problems until the last 6 months. I purchased the car from Gerald Jones Honda and have had all repairs and maintenance done there with the exception of tire related concerns and occasional oul changes. All the issues I've experienced have been engine related and in the same area of the engine. Consistent leaks, repeated warning lights, and loss of speed. I have replaced fuel injectors, a head gasket, and a turbo in the last 6 months. Despite those repairs, I'm still experiencing leaks and flashing warning lights. Honda currently has my car due to warnings again. They have indicated it is a performance issue but can't locate the problem. Even suggested I continue to drive the car as they have been unable to duplicate what caused it. I told them to keep it because that makes no sense for me to drive it as it seems unsafe to do so and I could potentially make matters worse. I've spoken to several 2018 Accord owners who have experienced the same issues. This is very concerning to me and crippling my finances. Honda stands out for their reliability, but regrettably the 2018 1.5L turbo doesn't stand up to Honda's reputation.

The contact owns a 2018 Honda Accord. The contact stated that while attempting to start the vehicle during cold weather, the vehicle hesitated while starting. The contact stated that while driving at an undisclosed speed, the vehicle independently went into LIMP Mode. The check engine warning light illuminated. The vehicle was taken to a local dealer, where it was diagnosed with a blown head gasket and a GDI injector failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 116,000.

This car had a manufacturer recall for the "fuel pump". I was advised by Honda to go get the car checked by the dealer to evaluate if the issues I was getting were related to the recall. I paid close to $400 to get the car diagnosed and about 3/4 months after that I was told that the part is available for the recall service. I got the repair scheduled at the dealership and got the part replaced. Ever since I got this fuel pump replaced, now the car is struggling to pickup. It looks like a miss fire but it doesn't show any errors on display. In this condition, this car is not safe to drive around as it is skipping the engine thrusts. I have looked at Honda website and other online resources and people are talking about these issues but HONDA hasn't said or done anything about it. It all started after I got the fuel filter replaced.

The 1000 miles or so, when trying to increase speed, would feel the gears slip between revolutions. I would let up on the gas pedal then slowly resume pressure, which sometimes worked or sometimes didnt. On April 19th while going up a hill on a side road, the car stalled and transmission warning light came on. I pulled over and shut the car off and restarted was able to slowly continue up hill at 15 miles per hour with the slipping becoming worse ( this is when I first called Honda to bring it in on Monday April 21.) I was able to arrive to work. After leaving work I pulled out of the parking lot and the car just stalled with all lights and warnings going off from engine to airbag warnings to tire pressure lights going off and dinging. This is when i called a tow truck to tow to the Curtiss Ryan Dealership. After talking to them at dealer they told me that other accords have had this problem.

This vehicle was built terrible. It had a blown head gasket at 86,000 miles. The head was warped. My valve guides and seals were compromised and leaking into the combustion chamber. I need a full head resurfacing job with new gaskets all around. New injectors and new valve cover gasket and everything around. This car has a design flaw and needs to be recalled for mediocre heads life. It almost caused me to get crashed from the back from a semi truck because the car decided to lose complete power while on the road. The cars recalls have been addressed but this whole issue with the faulty heads needs to be addressed. My vehicle is in the shop now and I will have to pay a little over $4,000 now. It's a hazard on the road when you get near to 90,000 miles.

Took in my vehicle to Rock Honda in Fontana at 125,000 miles for a second fuel pump recall. Two years ago my car stalled on me as I was driving on the freeway, it immediately decelerated from 65 MPH to 40 MPH, this happened before I had the first fuel pump recall fixed. Did the second fuel pump recall, and days later my car again began to decelerate from 50 MPH to 5 MPH. Brought it into the dealer and they told me my head gasket was blown.

The contact owns a 2018 Honda Accord. The contact stated while driving at an undisclosed speed, the vehicle stalled and shuddered. The contact stated that several unknown warning lights were intermittently illuminated. The failure had occurred on several occasions. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the spark plugs, and air filters needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 35,000.

Subject: Safety Complaint -?" Premature Head Gasket Failure in 2018 Honda Accord Hybrid (VIN: [XXX] ) Dear NHTSA Representative, I am submitting this letter as a formal complaint regarding a serious and premature mechanical failure in my 2018 Honda Accord Hybrid (VIN: [XXX] ). At approximately 96,000 miles, the head gasket failed, resulting in major engine problems and potentially unsafe vehicle performance. I am the original owner of this vehicle and have maintained it consistently in line with Honda-??s recommended service intervals. The engine has never been overheated or misused, yet the head gasket has failed much earlier than expected for a modern vehicle, especially a hybrid model. After researching online, I have found multiple reports of similar issues involving 2018 Honda Accord models experiencing premature head gasket failure, many of them under or near 100,000 miles. I am concerned that this may point to a widespread defect that could compromise the reliability and safety of these vehicles. A sudden head gasket failure can cause the engine to overheat, lose power, or even stall -?" all of which present potential risks to the driver and passengers, especially at highway speeds. I respectfully request that the NHTSA investigate this issue further to determine whether a safety-related defect exists and if a recall or manufacturer action should be issued. Thank you for your attention to this matter. Please feel free to contact me if any additional information is needed to support the investigation. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
