100k miles on our Honda when there showed Misfire in cylinder 3 kept coming up. Changed the coils and spark plugs. The car lost power on the freeway almost resulting in a collision. Had the car towed to Honda dealership where they quoted us 4800$ for a head gasket. Honda knows what they’ve done. I will never in my life buy another Honda.

I have changed turbo, coil packs, fuel injectors, spark plugs, battery, fuel pump and my vehicle still give misfire in cylinder 3. Honda knows it’s a turbo and head gasket issue and will NOT do a recall on this for the vehicles. HORRIBLE company. Will never buy another Honda

While driving, my 2018 Honda Accord suddenly lost power and went into limp mode with no prior overheating or warning signs. The acceleration dropped instantly, and the vehicle nearly caused an accident as it seized up in traffic. Diagnostic scan showed a P0303 cylinder 3 misfire, which is consistent with head gasket failure. The issue has been widely reported among other Honda Accord owners with the same engine, and it appears to be a recurring defect. This failure is dangerous because the car can lose power abruptly at highway speeds or during normal driving, putting drivers and passengers at risk of collisions. The vehicle was properly maintained and had no prior indication of internal damage or overheating. The head gasket failure is sudden and mechanical, not caused by user neglect. It needs to be investigated as a manufacturer defect before it leads to serious accidents or injuries.

ENGINE, POWER TRAIN
The car loses power. It starts as a misfire on cylinder 2 (P0302 code) and the engine starts to shutdown (or goes into a safe mode with no power). The result is loss of speed which creates a safety hazard especially on highways. This has happened multiple times and the car has been in the shop 4 times for this issue. We have to pull off the road, turn the car off, sit for a minute and restart the car. It will then run ok. This has happened during acceleration and when just trying to keep speed on an incline. The dealership has not been able to identify an issue. The head gasket was replaced in April 2025 because they thought there was a pin hole that was causing oil to push into the cylinder. The misfire continued to happen. It was in the shop on October 2025 and they found nothing wrong with the spark plug, induction coils, gas feed. Therefore no understanding of the root cause.

ENGINE, FUEL/PROPULSION SYSTEM
Bad fuel injectors reported by diagnostic testing done by Honda dealership after recall was completed on fuel pump. All warning lights on dashboard lite up and multiple warnings from car. This is a known issue with these specific Honda engines. Very costly repairs that if not completed can cause other engine issues.

I lost power to the vehicle in the middle of the road as I was accelerating uphill approaching a stop light getting ready to get on the on ramp to the highway. All the dashboard lights came on and the check engine light was flashing. I had to let my car idle it's way to the side of the road. I took my car to a Honda dealership. Diagnosis showed cylinder 3 misfire, coolant leaking into cylinder 3 indicating a blown head gasket. A couple of weeks before the loss of power to the vehicle, my car was sputtering and jerking when accelerating. It would get really bad when accelerating uphill.

I own a 2018 Honda Accord with approximately 131,000 miles. The vehicle suffered a blown head gasket that my mechanic identified as originating from a known design or manufacturing defect in Honda’s 1.5-liter turbocharged engine. They diagnosed the problem before they had my vehicle in their possession because they have already seen this so many times in other 2018 Honda Accords. The engine began showing symptoms such as coolant loss, rough idle, "Christmas tree" engine lights, and an overheating warning light. There was no sign of external coolant leakage. A professional inspection confirmed head-gasket failure. I have maintained the vehicle according to Honda’s recommended service schedule and have documentation for all maintenance. I contacted my local Honda dealership and Honda’s customer service department seeking goodwill or warranty assistance. Despite multiple attempts and escalation to a “warranty specialist,” Honda denied coverage and refused to contribute to repairs. The repair estimate exceeds $5,700, which is unacceptable for a vehicle with regular maintenance and a known pattern of premature engine failures. Online owner forums and public databases show many other reports of the same issue. I believe this defect poses a safety concern, as overheating or sudden engine failure can occur while driving, creating risk of loss of power, stalling, or fire. I am requesting that NHTSA investigate the widespread head-gasket and engine failures on late-model Honda vehicles equipped with this engine to determine whether a recall or manufacturer accountability action is warranted.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
I own a 2018 Honda Accord EX-L equipped with the 1.5-liter turbo engine. Over time, the vehicle began showing symptoms of coolant loss without any visible leaks, a sweet odor under the hood, and intermittent white smoke from the exhaust after startup. The engine would sometimes idle roughly and hesitate under acceleration. No external leaks were found by my mechanic. I later learned that these symptoms are consistent with a possible head-gasket or coolant-intrusion issue affecting this engine type. The problem poses a potential safety risk because coolant can enter the combustion chambers, leading to engine misfire, loss of power, or complete engine failure while driving. The issue has not yet been formally recalled, but I have seen multiple complaints and reports of similar failures in 2018–2022 Accords, Civics, and CR-Vs with the same 1.5-liter turbo engine. A warning light (“check engine”) appeared intermittently, and the temperature gauge fluctuated during normal driving. The problem has been inspected by an independent repair shop, but Honda has not provided a permanent repair or warranty coverage. The issue appears to be consistent with the allegations in recent class action filings regarding head-gasket and coolant-leak defects in Honda 1.5T engines.

While driving the car, the oil light came on and the engine died. Losing vehicle power while driving poses a very serious safety risk. After taking it to a Honda dealership, the mechanic diagnosed the following issue: "head gasket has failed causing coolant to leak into Cylinder 3".

Paint on the center roof of my car has been progressively getting white spots and paint defects. Paint has not been having these issues anywhere else on the cars body, but only has been an issue on the roof. I went to my local Honda dealer to see if there was a recall on my cars specific paint, but no recall was shown. There has been recalls for the same make and model of my car for this issue, but not for my paint code.

ENGINE, FUEL/PROPULSION SYSTEM
Head gasket leak after replacing recalled fuel pump. Took my car in for safety recall on fuel pump, just 24 hrs later every check engine light came on and my vehicle slowed to a stop (car went into limp mode). This happened on a busy street with vehicles flying by. I had my vehicle towed to Lancaster Honday (CA) where they did my safety recall the day before, they confirmed the head gasket leak. I had my vehicle diagnostics done at a different place as well and they confirmed the bad news, but also said this should not be happening to a new car with 66,000 miles. They advised I call corporate Honda and have them do a goodwill repair where the pay the repair since it is out of its 60,000 miles warranty. I had zero symptoms of this happening before it actually happened. I regularly had maintenance done on my car. I am very dissatisfied and disappointed that Honda just declined my goodwill repair after a month of waiting on them to “review the case”. I couldn’t be more sad and more screwed at this time. $5000 is not something I have right now to take care of something I shouldn’t have to. This is only happening to 1.5 liter Hondas in my certain year range. I wanted a 2.0 originally, but the dealership did not have any at the time so I am needing help. I will reach out to the ongoing pending lemon law case in CA to join the base and try to get my car fixed and have Honda do the right thing! I am not happy!

Driving on highway, check engine light went on and car lost all power would not go over 5 mph scared for my life as I was almost hit by other vehicles traveling at hi rates of speed . I managed to get the car to the shoulder. I turned the car off and restarted, and the car went back to operating normal. Car was checked by a friend who is a mechanic, and he told me there were codes for misfires after checking all the issues that could cause that type of problem he informed me that a pressure test on the coolant system revealed a blown head gasket which allowed coolant to leak in the cylinders causing miss fires due to the anti freeze extinguishing the spark of the spark plugs. I researched this matter and it's see to be a very common problem with many hondas with the 1.5 engine

Coolant leaking into head gasket which now needs to be replaced as it’s causing the whole car to shudder when acclerating and when not letting off the gas the check engine light will come on and the car will not drive anymore. It then needs to be turned off and on again to go away and won’t fix the issue with the studdering.

The contact owns a 2018 Honda Accord. The contact stated that occasionally, while driving at various speeds, the vehicle jerked and the engine lost compression. The check engine warning light was occasionally illuminated. The vehicle was taken to a local dealer, where it was diagnosed, and determined that the spark plugs needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was towed back to the same local dealer where it was diagnosed with a blown head gasket. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 112,000.
