I have a Honda Accord Sport 2018 Engine 1.5L Turbo(1.5T) Mileage- 97,776 I am reporting a suspected premature head gasket failure which is affecting my vehicle and my mechanic told me this has been going on for a while now with the Accords around my year model. On cold starts, the engine shakes and idles roughly for about 10-20sec. There has been some jerking during acceleration and prior stalling incidents. I have also experienced a blinking check engine light which indicates an active misfire condition. The vehicle has been maintained regularly and have proof upon request. The anti-Freeze is leaking inside the cylinder 2 and 3 which is causing the misfires. The check engine light which is blinking is causing safety concern due to potential power loss and the risk of stalling while driving. This issue appears to be widespread among vehicles equipped with the 1.5T but also around the years of my vehicle. Honda dealership brought it to my attention during the last recall, and my personal mechanic (independent service) diagnosed my car and mention the same thing. I believe this is a manufacturing or design defect and request that NHTSA investigate this issue for potential recall or required manufacturer remedy

First I had to replace all injectors and now I have a cylinder 4 misfire and need a head gasket job that’s being quoted at $5000!!! I’ve done all maintenance and upkeep and my car looks new. I’m in Honda groups and this is happening to everyone with the 10th generation accord that’s 1.5t engine. This should be a recall! I thought Hondas were the best. This is ridiculous and the car has no life. It’s literally in limp mode.

My 2018 honda accord 1.5T EX-L has a head gasket failure, creating the potential for the engine to misfire and stall while driving. The car has been well maintained with all scheduled maintenance done on time. The need for new head gaskets has been assessed by a local dealership, and quoted at 4500-8500 dollars. The spark plugs have also seized, and if they break off during the repair, then that adds $4000 to rework the top of the engine. I replaced the spark plugs at 120,000 miles and around the 140,000 mile mark I started noticing the car would occasionally misfire while accelerating. I replaced all 4 coils, and the misfire issue persisted. It is intermittent for now, but indicative of a head gasket failure according to the dealership. The issue is most frequent when accelerating to highway speeds- ie a highway on ramp. One time the misfire put my car into "limp mode" on a tight on ramp, forcing me to restart the car in a dangerous situation. The other time it happened, I was thankfully able to coast downhill to an exit to restart my car. In either case, it created a dangerous loss of power, and given the head gaskets are not a wear item- it should not be the drivers responsibility to replace the faulty part.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The day I purchased the vehicle from the dealer, every warning light began cycling on including the automatic emergency braking failure, engine system failure and others. I immediately took the car back to the dealer and they supposedly repaired it. When the car was returned to me, I drove it for less than a week and the same thing happened again. When the light came on, the car’s auto braking and cruise control stopped working. I took it back to the dealer and they said it was the head gaskets, which they fixed. When I got the car back again, I drove it for 2 days and it did the same thing again, this time all of the warning codes came on. This time, I had a total engine failure because the timing chain broke. The dealer took almost two months to replace the engine and it cost us almost $6,000. I got the car back last Saturday. Today, driving home from work, the automatic brake system failure warning came on again and the car won’t automatically brake and cruise control wouldn’t work. This is exactly what happened last time. I am afraid to drive this car because I don’t know if the brakes will fail and the system currently isn’t working. We are taking it back to the dealer which will likely cost us more money. We are stuck with this car and cannot get rid of it because we owe more money on it then it is worth because of replacing the engine.

The gas pedal failed to work on three separate occasions. The car essentially went into “limp” mode where the whole car stop driving out of nowhere. These models of Honda are known for the head gasket prematurely going out which has caused me car to have multiple misfires, warning lights, loss of power. The problem has been confirmed by the dealership and an independent mechanic.

ENGINE
I am writing to formally report a recurring and serious mechanical issue involving the head gasket in the 2018 Honda Accord equipped with the 1.5L turbocharged engine. This issue appears to be widespread and poses both safety and financial concerns for vehicle owners. In my experience, the vehicle began exhibiting symptoms consistent with head gasket failure at relatively low mileage. These symptoms included unexplained coolant loss, engine overheating, white exhaust smoke, rough engine performance, and in some cases misfires. Upon inspection and diagnosis, the root cause was identified as a failed or failing head gasket. This failure is particularly concerning because it occurs prematurely and without warning, despite regular maintenance and responsible vehicle use. A head gasket is a critical engine component, and such failures can lead to severe engine damage, sudden loss of power, and unsafe driving conditions—especially if overheating occurs while the vehicle is in motion. Additionally, the cost of repair is substantial, often ranging from several thousand dollars, placing an unexpected financial burden on owners. Many drivers, including myself, rely on these vehicles for daily transportation, and this defect undermines the reliability that is expected from a modern vehicle. There is growing evidence through consumer reports, online forums, and mechanic feedback that this is not an isolated incident but rather a pattern affecting multiple 2018 Honda Accord 1.5L vehicles. The consistency of these reports suggests a potential design or manufacturing defect related to the engine or head gasket system. Given the safety implications and frequency of occurrence, I respectfully request that the NHTSA investigate this issue further to determine whether a recall or manufacturer accountability action is warranted. Addressing this defect would help prevent further financial hardship and reduce the risk of unsafe driving conditions for affected vehicle owners.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
I experienced repeated stalling, loss of drive power while on the highway, limp mode, and all dashboard warning lights over several years. I brought the vehicle to an authorized Honda dealership multiple times and specifically asked whether these symptoms were related to the known fuel pump recall. Each time I was told the recall was not the cause. I was also told recall parts were unavailable or delayed. Based on dealership misdiagnoses, I paid out of pocket for multiple repairs including spark plugs and ignition coils which they claimed were the reason for my car acting up, that did not resolve the issue. Among other repairs I did on my own like replace the battery twice and what not. I have since received Honda’s official recall notice confirming that a faulty fuel pump causes the exact symptoms I reported. My vehicle is now completely inoperable it does not start and cannot be driven or transported. I have filed two claims with Honda Corporate, both denied based on mileage. I believe the vehicle’s failure is a direct result of Honda’s failure to address the recall in a timely manner and the dealership’s repeated misdiagnosis.

The contact owns a 2018 Honda Accord. The contact stated that while driving at various speeds, the vehicle either hesitated or stalled with the "Emissions System Fault", "Engine Power Reduced", "See your Dealer" messages displayed. The contact then received notification of NHTSA Campaign Number: 23V858000 (Fuel System, Gasoline), and the vehicle was taken to the dealer to be repaired under the recall. The vehicle was repaired, but the failure persisted. The vehicle was taken back to the dealer approximately six times after the recall repair. The spark plugs, ignition coils, and turbo charger were replaced after several visits; however, failure persisted. The vehicle was also taken to an independent mechanic, and the battery was replaced but the failure persisted. The vehicle was taken back to the dealer, and the contact was informed that the wiring harness and head gasket needed to be replaced. The manufacturer was notified of the failure and provided a case number, but offered no additional assistance. The vehicle remained with the dealer unrepaired.

POWER TRAIN
Rough downshifting and upshifting in low gears. Will slam into gears 2-3 often seems as though at slower speeds and cause driver and passengers to lurch forward. Will cause very rough acceleration at times and causes a danger in traffic given the speed becomes unpredictable. Transmission does not know what gear to be in. The ATF type 2.0 fluid change following dealer procedure after complaint has done nothing to change this lurching. This is putting me and other drivers at risk because I cannot control my speed when transmission is slamming in between gears. No warning lamps, undetected by cars TCU.

At 144000 miles all vehicle lights came on and vehicle engine would shake and vibrate. Computer said misfire on cylinder three. Changed spark plugs and coil. Problem still persisted. Mechanic recommended replacing fuel injectors so i did. After injectors were replaced all the lights came back on and the car runs worse. I believe its a blown head gasket now and the mechanic is testing the head this week.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: WARNING, LANE DEPARTURE: ASSIST
I keep having issues where my car thinks I’m changing lanes and alerts me, when I’m not, and auto-corrects my steering which has led me to actually veer into another lane and fighting the car essentially while driving. I turn the feature off and somehow it just keeps happening. Same with the sensor that auto brakes - there won’t be anything that the car should be braking for and I’ll get the flashing BRAKE text come up on dash and beeping before it completely brakes on its own. These issues and features have been more worrisome and scary than helpful. There are multiple instances

ENGINE
I own a 2018 Honda Accord EX-L with a 1.5L turbocharged engine. The vehicle began overheating while idling and at low speeds, cooling down when driving at higher speeds. I brought the vehicle to a Honda dealership where a pressure test confirmed internal coolant loss with no external leaks found. The dealership diagnosed a head gasket failure and recommended replacement at a cost of $8,941. The component that failed is the head gasket on the 1.5L turbocharged engine, allowing coolant to leak internally into the cylinder. My safety was put at risk as the vehicle overheated while in traffic during normal driving conditions, creating a risk of engine failure, loss of power, and potential fire. The problem was confirmed by a certified Honda dealership via cooling system pressure test. A goodwill request has been submitted to American Honda on my behalf. Warning lights appeared on the dashboard twice indicating to turn the vehicle off immediately due to overheating. Symptoms first appeared in April 2026. I am aware of NHTSA TSB MC-10234626-0001 and an active class action lawsuit Bissell v. American Honda Motor Co. Case No. 3:24-cv-02286 addressing this exact defect on this exact engine.
