2018 HONDA ACCORD Complaints

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".

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!

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.

headgasket blew at 73k miles out of nowhere no check engine light no smoke no warning nothing car was taken care of its whole life car locked up during headgasket failure almost causing accident on road near house called Honda to explain the mishap they were snotty and acted like they didnt care wouldn't provide repair for free or even ask me if I was ok or if I needed help. I am a part of a 1oth generation honda group on Facebook and there are alot of us who should be helpedfor this very dangerous and random mishap

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.

My 2018 Honda Accord at only 63,000 started to lose power and all the emergency lights went on. Diagnosed as a misfire and now requires a new head gasket. This was told to me by the dealer to be a well known problem with the 1.5 T 2018 Honda Accord.

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.

My 2018 Honda Accord EX is currently having FUEL injector problems at 41,000 miles. Honda is trying to tell me that FUEL injectors do NOT get affected by the recalled FUEL pump. This is very silly because the FUEL pump and FUEL injectors work together. They want $1,800 to replace the FUEL injectors at Honda. I already completed the recall on the FUEL pump, and afterward, they told me my injector was running too rich and needed to be replaced for $1800. There are so many Honda 1.5Ts experiencing these same issues, and Honda does not want to do anything about it. I am currently taking my car to a local shop to get the FUEL injectors replaced for $1,327. I believe I should be reimbursed since the FUEL pump is what caused my FUEL injectors to fail. Honda is trying to tell me that two FUEL components of a car don’t correlate with each other? This isn’t fair, and I need to be reimbursed.
