• 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
2018 Honda Accord engine complaints
Page 13 of 21: complaints 341 to 370 of 587, newest first, as owners wrote them.
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 the federal safety agency. 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.
Engine keep going into limp every now and then and it’s pretty dangerous especially while driving on the highway. All the lights would come on the dashboard. On May 2 it almost cause an accident because it happened while I was driving on the freeway and I’ve changed spark plugs, injector my battery and it’s happening

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.
Scanned for codes. Found P0303, P0299, and P2243 stored. Found coolant entering cylinder 3. Found excessive play in the waste gate rod and found A/F sensor is not responding. Needs head gasket. Vehicle starts up and runs rough. All alerts on alerts on dash on cust states check engine light on. Honda sensing alerts on.
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.
Head Gasket Leak at 75,000 miles, eventual blown head gasket due to lack of symptoms beforehand
I got a recall notice for my car for fuel pump which I got it fixed but now the dealership is saying I got fuel injector issues with head gasket issues. I have also read online that lot of people are having exactly this problem, their fuel pump injectors are also failing with head gasket on the 2018 Honda Accord and Honda is requesting $2000 in fixes
Apparently the recall was fix with the fuel system, however the car is still losing power as you drive it.
My car started misfire .. all the lights went on the dashboard .. had to get it towed .. headgasket issues
The contact owns a 2018 Honda Accord. The contact stated that while driving on several occasions, the vehicle lost motive power and was almost rear-ended. The vehicle was steered to the side of the road and restarted. The vehicle was restarted, and several unknown warning lights were illuminated, and unknown messages were displayed. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was unknown.
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.
The contact owns a 2018 Honda Accord. The contact stated that while driving 25 MPH, several unknown warning lights illuminated on the instrument panel. The vehicle returned to normal functionality, but the failure became a regular occurrence. The vehicle was taken to an independent mechanic, who determined that the turbocharger was not producing the expected boost pressure. The contact was informed that the OBD was reset, and that the vehicle needed to be taken to the dealer. The vehicle was not repaired, and the unknown warning lights were again illuminated on the instrument panel. The manufacturer was not notified of the failure. The failure mileage was 142,000.
I am reporting an issue with the fuel injectors on my 2018 Honda Accord. It is a known issue but has no recall. Honda has no replaced the fuel pump on my vehicle yet. I have read of multiple issues with the fuel injectors and/or the head gasket going bad on the Accords. I noticed a knocking sound in my engine and a loss of acceleration power. I took my vehicle to the dealership and they reported an injector failure but it was not covered by Honda. My vehicle has less than 70,000 miles on it at this time. I believe the injectors need to be under a safety recall for the Accords.
I recently took my car to the dealer because I have multiple messages on my dashboard saying please see dealer dealing with my brake system, electric power steering, vehicle ability assist, collision mitigation system problem, etc the dealers don’t know what’s going on with it. I recently had service done on it because of the recall with the fuel pump and even before that those messages were showing up.
Car has 164352 miles and has had a transmission replaced and a head gasket replaced. The head gasket is a known issue from what I have seen and there needs to be a recall. I have read time and time again about these cars needing a head gasket. Please add this to your list. Total repair for transmission, $3600. Total repair today for head gasket, $2913.
As my car falls under this law suit and no legal action has been taken for it, I'm reporting that the Head gaskets for the 2018 Honda Accord Sport 1.5L are not properly designed for the wear and tear on a 1.5L turbo. I'm not great with describing car and there internal functions, so please refer to the active court case (3:24-cv-02286). This is an on going issue with the 1.5L Accords and is well known by the company. This issue typically comes with a ~$4500 replacement of the Head Gasket. In my case, I also head to replace 2 injectors that the dealer ship was saying were read as feeding rich. A common diagnostic that can also be caused by Coolant Leaks. These problems causes my car to flare every warning light available. I have no heat from the heater. My car sometimes won't shift or go into gear. I've yet to get this fixed as the mechanic is still awaiting word from me to proceed, so I don't have a invoice for the Head gasket repairs.
Engine can randomly blow a turbo of head gasket while traveling on freeway making you stranded in middle of the freeway and disable all the safety features while doing so. Extremely danger

The components and systems that are failing and malfunctioning in my 2018 Honda Accord are the engine, head gasket, fuel, injectors and turbo. While in motion, the car jerks and has issues with acceleration requiring the safety hazard lights to be come on and I’m unable to keep up with marked speed limit while traveling due to the sluggishness of the vehicle. The majority of these issues have been confirmed by a Honda dealership as well as another car shop. There are several warning and safety hazard lights that come on and go off the dashboard. Many times, I have to pull on the side of the road due to not being able to drive this vehicle.
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!
February 2025 All the warning light on in my car came on. I took it Honda where they had me pay $250 for a diagnostics. At 85K miles, that's when I found out a had a blown head gasket and need a replacement.They also suggested a new fuel injector. They quoted me $7,000. My warranty just expired. This was my car and I didn't know anything about warranties and renewals. I always go to go Honda for my services and I had just visited a few weeks prior and they didn't see anything wrong my car. The Honda service guy told me to car it to the nearest Carfax because my car and sell it. I was so distraught. Now I'm trying to figure out how to get the money to pay for this.
Three times, while driving, the car went into limp mode and would not accelerate. Had to pull over, turn car off, and back on to fix the issue. Have had it looked at and they have mentioned engine coils and a new control module. Had it at the dealership in January and they did their full inspection and to fix fuel pump recall and didn’t mention any issues regarding this.
