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.

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.

Cylinder 1 and Cylinder 3 misfire (Cylinder 3 misfired multiple times, even after attempts to fix it), and now I have a blown head gasket. On more than three separate occasions, my car has either stopped completely in the middle of the road-?"sometimes on the highway in the fast lane, with cars traveling 80+ mph behind me, putting my life at significant risk-?"or it will suddenly drop from the speed of traffic (80+ mph) to under 30 mph in a matter of seconds, out of nowhere. If it weren't for me swerving into an open lane to the right one time, I would have undoubtedly been rear-ended by a car traveling 80 mph. In that instance, my speed went from 0 mph to less than 30 mph in just seconds, which could have easily paralyzed me or even killed me had I hit my head on impact. Though I didn-??t sustain a physical injury the first time this happened on the freeway, I did suffer a panic attack due to the sudden and extreme danger of the situation. Yes, the problem has been confirmed by two separate Honda dealerships at different times, but both were caused by the same issue. The vehicle has been inspected by the manufacturer, as I had it checked at two different Honda dealerships. No, there were no warning messages or symptoms prior to the failure; all issues occurred suddenly while driving, when my car barely started producing any power on the freeway.

While waiting for the recalled parts to be in stock for the fuel pump module, my car starting running rough and going into limp mode several times a day. Thus causing near accidents with my children in the vehicle. After getting the fuel pump module recall fixed I asked and had to pay for a diagnostics test to see what was causing the car to do this. We were told it was the fuel injectors and were quoted $2000 to replace those. That was done 4 days ago at the dealer, and it happened again yesterday! We took the car back to the dealer today and they have just informed us we need to replace the head gasket & turbo and had a coolant leak causing these issues?! Why that was never seen in the original diagnostics test nor a problem 4 days ago, but after spending $2000 we did not have to keep our family and others safe, we are now being told it will cost over $5000 to fix these now issues. We can-??t afford that and now I don-??t know what I am going to do! Honda needs to step up to the plate and take some culpability here and be responsible for what clearly appears to be a much needed recall for 2018 Accords! This is ridiculous. And for the service advisor to tell us this happens all of the time to these, if not daily, should speak volumes!

Randomly, my car will start throwing many warning signs when I crank my car. Then it magically disappears after 2 days. Also I drive my car past 40mph and the engine light came on and then I could no longer accelerate. My car was slowing down while I was on the freeway. I pulled over, turned my car off then back on. Everything is back to normal. Next day, I crank my car, warning signs again and then disappears. I took my car to the auto shop and they could not find any codes. I have videos and pictures. There-??s also a Honda Facebook group with my same model car reporting the same behavior.

Christmas Tree dashboard with all lights on appeared a few weeks ago. Took car to auto shops twice. First time I was told coil 1 for cylinder 1 was misfiring, replaced with new coil. Lights did not go away, got my codes read again and was same error message of coil 1 misfire. In the past week car would not accelerate past 15mph after start up. I was immediately concerned it was a head gasket issue since that is a very known defect for my exact make and model of vehicle. Took into my Honda Dealership where I purchased my Accord brand new. Was just told Fuel injectors need to be replaced even though vehicle has been maintained properly. To me this seems this is directly correlated with the current fuel pump recall issue, I asked the service advisor if that was the case and she said she-??d get back with me, and that she-??s currently waiting to hear back from my Lifetime Powertrain Warranty company (Fidelity Warranty Services) to see if the fuel injector replacement is covered by them. If this make and model has time and time again been known to have faulty fuel injectors and head gasket issues that directly put the drivers safety at risk and end up causing thousands of dollars in repairs, Honda needs to take responsibility for rushing out vehicles without properly testing them first. If fuel injectors are not covered under my warranty, I will be contacting American Honda to assist me with the cost of the repairs.

I was on the highway with moderate traffic. My car would no longer accelerate due to a blown head gasket out of nowhere, I was on the far left lane and had to traverse over 5 lanes in moderate traffic while other drivers on the highway were going 60+ mph. This is a common issue among Honda Accords with the 1.5 engines.

Hi, I would like to address two issues separately for my 2018 Honda Accord 1.5T 6MT; one dealing with the open recall and one dealing with how the vehicle operates dangerously due to poor programming under specific operating conditions. To add, I speak as an engineer working in the automotive space specifically on the design of ADAS and AV systems with ISO26262 and SOTIF in mind. 1) There is an open recall for my vehicle for a fuel pump issue. I am experiencing some of the symptoms of this issue, specifically, my car will hesitate at around 4000 RPMs during acceleration. I immediately back off the accelerator and then the check engine light flashes and I lose all engine power. I then restart my vehicle and it operates more or less normally with the occasional illumination of all the dash lights. I have taken my car to the dealership expressing my concerns (Braman Honda of Palm Beach in particular) and they said they cannot do anything about it unless since there are no parts. I have paid for them to diagnose the issue but since they cannot recreate the issue (as it is intermittent) they cannot do anything. Question: what is the point of a recall if a vehicle experiencing the symptoms that lead to the recall cannot be repaired due to "part shortages"? 2) I want to talk specifically of the vehicle programming to cut engine power off. I think I have a separate electrical issue that causes all the lights on the dashboard to go off and again cut engine power. I understand that engineers may want to design their vehicles to cut power off when there is a potential mechanical failure, but in this case the issue is purely electrical. The fact that I can restart my car and accelerate normally shows that the issue is not mechanical. I believe this programming needs to be addressed. To be frank, losing engine power while driving on the highway may lead to catastrophic consequences. I feel that my vehicle is unsafe to drive since it has happened to me multiple times already.

While taking off from a full stop, the vehicle's transmission shifted violently to the point where it felt as if the car was rear-ended. This is an issue for which I've filed numerous complaints before with NHTSA knowing about the problem by now, and having done nothing to initiate a recall. I have also taken the car to the dealer who failed to properly diagnose the issue. Finally, another mechanic did provide me with an entry from Honda where they sort of admit to the issue. The fix, of course, is to replace the valve body or the whole transmission. Hence, due to NHTSA sitting on their thumbs, thousands (maybe, hundreds of thousands) are now stuck with a vehicle which will need a multi-thousand dollar repair outside the warranty and NHTSA did not properly investigate the issue and push the manufacture to issue a recall.

Numerous Honda Accord 1.5T have blown head gaskets, numerous complaints of this happening during freeway travel. The car will suddenly go into a "limp mode" and won't let you travel over 20mph. This could cause an accident. Numerous examples of this can be found on YouTube, Facebook, Reddit, and other social media outlets. Honda Service Techs explained this happens because of weak head bolts that stretch overtime due to pre detonation. most commonly accruing between 20,000-75,000 miles. No recall, extended warranty, or TSB has been issued by Honda, often leaving the owner with a bill between $5000-$10,000.

I was attempting to accelerate on the acceleration ramp to merge into traffic on the interstate, when my vehicle began violently jerking, and suddenly lost all power. My check engine light came on and it went into limp mode. This has happened twice now. Both times I was able to make it safely into the shoulder of the road with my hazard lights on. I turned the vehicle off, reset it, and have had to drive it since. The warning lights are on and off, depending. They-??ve had since December of 2023 to release a recall and they haven-??t yet. I need a remedy.

These Accords are an extreme safety hazzard. Experienced an instant loss of power and without any prior warning signs. Once the issue accured the vehicle was impossible to drive putting the vehicle occupants and everyone on the road at risk. Now Honda does not want to fix the problem because they feel that would be an admission of guilt. This is not the first I've heard of this issue with these vehicles and I'm sure it will not be the last please help push these vehicles for a safety recall before more people get hurt.

My 2018 Honda Accord 1.5 turbo (original owner) 77,000 miles. Started having numerous warning lights on dash and vehicle was violently shaken. On several occasions, vehicle had no acceleration over 10mph which caused me to have several close calls on the highway. Took it to Honda dealer and they stated that I had a blown head gasket and the repairs would cost five thousand eight hundred dollars! Unfortunately i have read numerous posts on Honda forums and hundreds of customers with the same vehicle year and model are also reporting the same problems. Honda will not pay for any repairs since it is past warranty. This needs to be upgraded to a recall by Honda, very upset customer!

I got a blown head gasket to cynlinder #3 at under 100k miles. I maintain it regularly as needed by use of the maintenance minder. Never got any indication of engine troubles before. On doing some research this seems to be a common problem for this make and model and seems to be a possible defect. The repair was $4300 to repair the head gasket.
