I went to enter the highway and the car would not accelerate and the check engine light was flashing and went into a limp mode. I got it looked at it it was giving me the misfire code for cylinder 2. I paid over $1k and had all the spark plugs replaced and coils. It was fine and then 6 days later it happened again. The mechanic looked at it pressurized with the bore scope and saw coolant. Then we knew it was the head gasket. This is crazy especially with Hondas being known for reliability. I-??m at 87k miles and have been seeing that this happening to many others.

All of the lights in the dash came on. We took it to Honda, at first they said it was the coils and spark plugs. I had them replaced, the same thing happened again the computer read that it was misfiring on one of the cylinders. They kept it and ran several tests. They then tried to say that it the result of a bad oil change but we knew better. After about a month they said that it had over heated and blown the head gasket. I ended up having to use my warranty and pay a deductible.

I own a 2018 Honda Accord (1.5L Turbo Engine) and I have kept regular maintenance on the vehicle. I currently have 146,600 miles on the vehicle. I begin having problems last year as I was leaving work and my vehicle wouldn't start. I waited a few minutes for the vehicle to start and it started and several malfunction lights came on the dash including the engine light. I had a 30 minute drive home and as I was driving home the vehicle didn't want to pick up speed to the speed limit of 65. I drove slowly home. I had already made an appt with the Honda Dealership where I get my car serviced for an oil change a couple days before. The next day I had a family member to follow me 30 minutes away to the dealership to drop my car off. When I dropped the car off I told the service technician about the problem. Later that day the dealership's service department called to tell me that I my head gasket had blown and it would be around $4500 to repair. I began to ask questions as to how this could happen I had kept up with regular maintenance. The service technician begin to tell me different reasons, and I asked how when I had regular maintenance and some suggested maintenance required as well. I had my vehicle towed from the dealership to get a second opinion. The technician I took my vehicle to was authorized to work on Honda vehicles, and he asked me if I was aware of the complaints customers were having about their Honda 2018 (same model) was having about leaking coolant, cracked or blown head gaskets on cylinder 3. I told him I was not aware so I went and did research and found there were numerous complaints about the same problem I am having and Honda was not acknowledging the problem or people had the repair done which cost a couple thousand dollars only to have their cars still not working properly or getting the same malfunction lights. Now I have to look for another car. Honda's are supposed to last.

The Head Gasket is leaking at 135k miles after changing oil and filter every 5k miles and flushing coolant every 50k. Just a cursory internet search will show you how obvious the design defect is in the head bolts of the 1.5 liter turbo engine and they should be recalled.

Blown Head Gasket after taking my car in to Honda cars of Rock Hill SC, I had no issues, only took it to have the Fuel injector recall done, they did a diagnostic nothing came up, they did the fuel injector recall repair, and they asked if they could do the oil change i told them yes, a week later, my car lost power on interstate 77N in rock hill south carolina. I was going about 70 mph and it dropped from 70 to 20 mph in a matter of seconds, i had little time to get out the lane, i could have been killed or killed someone else i was terrified. Every known light on my 2018 honda accord came on, I have a video of the lights on my dashboard. I had it towed back to honda cars of rock hill on 5/30/2025 and was told I had a blown head gasket...I asked them how, they just put a fuel injector and nothing else was wrong with my car. they told me cost is $5500, i told them there as nothing wrong with my car prior to them doing the recall, Matt told me there was nothing i did, so i asked him what did they do to my car, I need them to replace my motor who knows what other damage happened my car had no issues.

The contact owns a 2018 Honda Accord. The contact received notification of an unknown recall. The contact stated that while driving at various speeds on several occasions, the check engine warning light blinked, and the vehicle lost power. The vehicle was restarted after each failure. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

My 2018 Honda Accord has become unsafe to drive. The car will not go over 15 mph, all the warning lights on the dashboard are on, and the engine and transmission feel shaky. The entire car shakes when I try to drive it, and it seems like multiple systems are failing at once. This happened suddenly and has made the car undriveable. My safety was put at risk because the loss of power happened while I was on the road. The problem has been looked at by my independent mechanic, but it has not been resolved. The vehicle is available for inspection.

On 2025-06-12 at about 3:50 PM EST I triggered a remote start command from my phone via the HondaLink app to cool down the car before leaving work. When I went out to the car it had not started. I assumed the command had simply failed, so I returned home and parked in our attached 2-car garage at around 5:10 PM. At about 6:30 PM I opened the door between the house and the garage and heard an engine running. The car was found to have spontaneously started itself. I do not know precisely how long it had been running. It took me a couple seconds to recognize the situation and the danger, and once I realized what had happened I immediately closed the door to prevent carbon monoxide from entering our house. I tried accessing HondaLink to shut down the vehicle remotely but the app gave a message "Services Currently Unavailable". In order to safely shut it down, I opened the garage doors, waited a couple minutes for the garage to ventilate, then quickly moved in and shut down the engine while avoiding breathing in. We noticed a smell of fumes in our house near the connecting door. Both keys were in static locations (not in pockets, etc. where the buttons could have been accidentally pressed). They had been that way since I got home. I believe that HondaLink's servers sent the remote command to my vehicle *significantly later* than the command was requested. This is a major problem and safety checks should prevent a delayed command from having an effect on the vehicle, especially when dealing with engine start commands. The carbon monoxide buildup fortunately seemed to be minimal, although I am again unclear exactly how long the engine had been running. The vehicle will normally shut itself off 10 minutes after a remote start. However, the most dangerous situation would have been if the car shut itself off and then someone entered the garage shortly afterward without realizing that the vehicle had been running.

Car falls into limp mode in traffic when a misfire is detected. I have had a mechanic investigate the misfire and has determined coolant in the cylinders, indicating a blown head gasket. This is a widely reported problem with this engine and the large number of complaints indicate this is a safety issue caused by Honda.

Honda -?? No warning, Honda at first thought it would be fixed by fixing the factory recalls.

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.
