2018 Honda Accord complaints

All of my dash lights are on.

I was traveling North on Highway 55 in Huntsville, AL when I put the car in sport mode all of the error lights came on immediately. This has happened on several occasions. My passenger seat belt error always comes on. When I call about getting the recall fixed it could never be done because the dealer ships says the parts are not available.

Car seem to misfire alot , having a lot of head gaskets issues aswell as turbo issues, 10s of 1000s of people like me are experiencing these common problems, taking so much money out of our pockets when its should be handle the correct way

The contact owns a 2018 Honda Accord. The contact stated that multiple warning lights were illuminated on the dashboard prior to any issues. The contact stated that while driving at an undisclosed speed and entering onto the highway, the vehicle slowed down on the highway and eventually stalled. The vehicle was able to get safely to the side of the road. The vehicle was towed to the dealer and diagnosed with a high pressure fuel pump failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure milage was unavailable

The SRS (Supplemental Restraint System) warning light is lit up on dashboard. Does not go away. Mentioned it to the dealership and I was told having items in the seat could trigger it or if there not enough weight. But even if there nothing or someone in my passenger seat the SRS aways come up.

While driving the car it went in to limp mode, restricting the ability to maintain normal driving. It did this because the head gasket needs to replaced because coolant is leaking into # 3 cylinder. My wife and others were put at risk when she had to pull over in an area that was unsafe according to a Summerville police officer who came to her aid and helped her get the car to a safe area.

I own a 2018 Honda Accord with approximately 108,000 miles. My vehicle has experienced ongoing fuel system and drivability issues connected to the fuel pump recall. It took over two years for Honda to complete the recall repair due to delays and lack of available parts. During that time, my vehicle developed additional issues including failed fuel injectors that required replacement. Even after those repairs, the vehicle continues going into limp mode, causing loss of power and creating a serious safety concern while driving. When I brought the vehicle to Honda for diagnosis, I was charged approximately $180 just to scan the vehicle and then quoted nearly $4,000 in additional repairs. In addition, my vehicle experiences what many Honda owners refer to as the “Christmas lights” issue, where multiple warning lights suddenly illuminate across the dashboard at the same time. This appears to be a widespread complaint among owners of this model and is often associated with ongoing fuel system, electrical, or sensor-related problems. Honda vehicles are marketed as reliable, yet many owners of this model have reported similar problems related to the fuel system, injectors, limp mode, and dashboard warning light failures after the recall issues. I believe the prolonged delay in addressing the recall contributed to further damage to my vehicle. Honda should take responsibility for these known issues and provide assistance to affected customers.

The contact owns a 2018 Honda Accord. The contact stated that while driving the vehicle she noticed a power issue with the vehicle, thinking it had to do with the battery, the vehicle was misfiring. The vehicle was towed three times to the dealer, where it was diagnosed with a engine failure. The second tow was to a independent mechanic, and the third time the vehicle was taken to a dealer where it was diagnosed to have a engine gasket failure. The contact was informed that there was a coolant intrusion in cylinder #2. The contact was informed that the head gasket needed to be replaced. The vehicle was repaired. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 73,000.

The head gasket malfunctioned/ broke. It has been confirmed by the Honda dealer where I currently have my vehicle. There were no messages or symptoms prior to failure. My safety and others were put at risk because my vehicle began to turn off as I was driving up a hill with no warning. The vehicle began to decelerate.

Vehicle: 2018 Honda Accord On [XXX], at approximately [XXX] PM, I was driving on [XXX] [XXX] at approximately 35 mph. The weather was clear and the road was dry. A vehicle ahead of me began turning into [XXX] N. My vehicle’s Collision Mitigation Braking System / automatic emergency braking system activated suddenly. The system made an audible warning sound, displayed a warning icon, and applied braking even though I did not believe there was a crash-imminent situation. There were vehicles behind me at the time, so the unexpected braking created a potential rear-end collision risk. The braking event also caused back pain, and I later experienced some stomach discomfort. I am concerned this was a false activation of the automatic emergency braking / Collision Mitigation Braking System. I am also concerned because the system reactivates after the vehicle is restarted, meaning I cannot reliably prevent another unexpected braking event from occurring. I am requesting that this be documented as a vehicle safety concern involving possible false activation of the automatic emergency braking system. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving vehicle detected both road departure and engaged the emergency automated braking. The vehicle attempted to correct the "road departure" by steering the vehicle away from the perceived problem and engaged the brakes nearly causing a collision as it has done numerous times before. I have reported this to NHTSA and American Honda multiple times and await a repair of this dangerous issue. Honda has opened a case on this but have had 18 months and no response has been issued.

The head gasket was blown on highway even though the car was functioning perfectly fine and was well maintained.

Car was failing in 2024 due to fuel recall. It was fixed by Webbs auto shop. Now 2026 recall shows with DMV and Honda is failing at providing a proof of correction after Inspecting the car and approving all the changes made to it. I am unable to get my car tags due to Honda failing to comply with what DMV is needing to complete this request for my tags.

My car is 2018 accord 2.0t The car just started jerking then I brought it to honda they said head gasket replacement needed, my car was properly maintained and it still happened

- the car's automated systems randomly applies severe breaking at improper times - the cars head gasket has blown and in turn has blown the radiator and thermostat

I own a 2018 Honda Accord equipped with the 1.5L turbo engine. The vehicle is experiencing a head gasket failure consistent with numerous complaints reported by other Honda owners online and through NHTSA. My vehicle began showing symptoms including rough cold starts, engine misfires, loss of coolant without visible leaks, and reduced engine performance. Diagnostic testing indicated head gasket failure and coolant intrusion into the cylinders. The repair cost quoted to me is extremely expensive. This appears to be a widespread defect affecting 2018 Honda Accord 1.5T vehicles. Many owners are reporting similar failures at relatively low mileage, often involving cylinder misfires, overheating, coolant loss, and major engine damage. This issue creates a potential safety hazard because the vehicle can suddenly lose power, enter limp mode, or stall while driving. Honda should investigate this issue and provide assistance or recall coverage for affected vehicles. Consumers should not be responsible for major engine repairs caused by an apparent design or manufacturing defect. Vehicle: 2018 Honda Accord 1.5T

Blown head gasket after multiple spark plug replacements for misfires.

The head gasket failed on my 2018 Honda Accord 2.0T at 81,000 miles due to weak factory head bolts stretching under turbo boost, causing cooling system over-pressurization and risk of engine stalling/overheating

1) The cylinder head gasket was “blown” and leaking coolant into cylinder 2. 2) As I was merging into traffic, my vehicle suddenly lost power and entered limp mode and the check engine light began flashing. 3) Yes, serviced at the dealer and confirmed 4) Inspected by dealer 5) No

I am filing a safety complaint regarding my 2018 Honda Accord equipped with the 1.5L turbocharged engine. The vehicle has experienced repeated engine-related failures despite multiple repair attempts by an authorized Honda dealership. Problems have included dashboard warning lights, engine misfires, loss of power, fuel odor, and suspected head gasket failure. Most concerning, on September 20, 2025, while exiting a highway with my child in the vehicle, the car suddenly lost power and all dashboard warning lights illuminated simultaneously. The vehicle became inoperable in traffic and required towing. This created a serious safety hazard and could have resulted in an accident. The vehicle has been returned to the dealership multiple times for the same or related issue on the following dates: • July 8, 2025 – mileage 80,099 • July 10, 2025 – mileage 80,101 • September 20, 2025 – mileage approximately 82,000 • October 27, 2025 – mileage 84,453 • October 28, 2025 – mileage 84,473 • April 16, 2026 – mileage 93,812 Repairs have included replacement of the high-pressure fuel pump and repeated diagnostic inspections, but the issue remains unresolved. I understand many owners of Honda vehicles equipped with the 1.5L turbocharged engine have reported similar problems involving head gasket failure, coolant intrusion, misfires, overheating, fuel system issues, and sudden loss of power. I am concerned this defect presents a significant safety risk.

The engine stalled on the freeway. Has been having rough idles on cold start. Water gurgling/sloshing sounds coming from behind the dash on cold start. White, sweet smelling smoke periodically comes from the exhaust. Followed up with spark plug replacements. The vehicle still has all previous issues. Upon further inspection coolant reservoir is empty indicated a leak. No leaking fluid has been found. Suggests internal leaking. Issue is likely failing head gasket issue. Bissel v. American Honda Co. has been suing over this issue. The head gasket is allowing coolant into the cylinders mixing with fuel causing misfires and stalling the engine. Extremely dangerous. Likely to cause accidents.

My car is having issues with the head gasket. My car check engine lights came on like a lit Christmas tree with many warnings (Emission System, Brake System, Departure, Uphill and many other more). I took my car into Capital Honda for a diagnostic on 5/4/26 and they informed that it was the head gasket that needs to be replaced. They are charging me $6000 to repair and do not have the funds to fix. Also I contacted Honda Corporate since I read on google that I may qualify for the goodwill program and they said I didn’t qualify since I did not purchase warranty on the vehicle when I got it. I also do see that there is a lawsuit in place for this. I’ve kept up with my car maintenance and never had an issue till now. The car is running rough and it’s shaking a lot. It’s also loosing coolant from the reservoir.

The head gaskets and turbo supercharger goes out at a certain amount of miles

While driving at highway speeds, the vehicle experienced a sudden jerking and a catastrophic loss of motive power (Limp Mode). Simultaneously, multiple safety systems failed, including the Collision Mitigation Braking System (CMBS), Adaptive Cruise Control, and Road Departure Mitigation. The vehicle became a road hazard in active traffic. A certified Honda dealership technician inspected the vehicle and confirmed a premature head gasket failure with coolant intrusion into cylinders 2 and 3. The engine is non-drivable and the vehicle is at 84,000 miles. Despite the documented nature of this design defect and its current litigation, American Honda Motor Co. has denied any assistance. The vehicle also has an open safety recall (24-009) for a fuel pump failure which presents identical safety symptoms.

I have a 2018 Honda Accord 1.5 sport and it had a premature head gasket failure at 78,880 miles. This is a well known issue with this engine. When I took the car in for repairs at Nalley Honda in Jonesboro Georgia the head mechanic at the location said these engines were not built right and he has seen an extreme amount of premature failures on this type of engine. He had been with Honda for 25 years and said he expected a recall on this and to keep my receipt on the repair. Hondas are usually known to be great cars and that has been my experience in the past, but this specific model does not pass expected reliability standards for a car! A $6K head gasket repair at 78K miles is not reasonable. I see that there is a class action lawsuit on this car for this same head gasket issue which shows that this is not a one off issue. Please issue a recall for this car and protect all the people who are on the hook for this ridiculously expensive repair at no fault of their own.

Car is constantly misfiring! I got my fuel injectors, plugs, coils all changed. Honda is now saying head gasket! Why isn’t this being recalled! I am seeing multiple people with the same head gasket issue.

All lights on head dash are on , all components are not working properly or effected because of this. (Engine light brake light abs light tire light traction control light , sensors out all) while driving vechile reduces power does not operate randomly , have to pull over shut the car off and turn it back on. Has high vibrations lot of shaking, stauling. I have had it looked at with multiple shops and dealer . Everybody is playing a guessing game and can not pin point what exactly it is . Was told it was spark plugs and coils, alternator , fuel injectors. ALL have been repaired, and still have all lights on dash and still facing every problem listed after repairs. Been inspected by manufacturer. Say not been resolved was told if it wasn’t what was already fixed they don’t know and that this is very common right now . It first APRIL 2026 (3) times. May 2 times 2026

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.

Blown head gasket

The door handle is coming off where the key part is and handle part it.

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.

Car keeps throwing cylinder 2 misfire, replaced all spark plugs, fuel indicators and still having issues. Think it’s the ecm/pcm is bad or there’s a bad connection.

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.

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.

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 starting the vehicle, the climate control feature was inoperable. In addition, the contact stated that after driving for approximately 5 miles, the engine overheated. A message to park the vehicle was displayed. The vehicle was taken to the dealer, where it was diagnosed with head gasket failure. The contact was informed that there was a coolant intrusion in cylinder #3. The contact was informed that the head gasket needed to be replaced. The vehicle was not repaired. The vehicle was undriveable. The manufacturer was not made aware of the failure. The failure mileage was approximately 106,483.

Head gasket failure, Over heated randomly putting myself and kids unsafe and at risk for accident. Been confirmed by independent service center. Not inspected by police or insurance. Had cylinder misfire a week prior.

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. The failure mileage was approximately 40,000.

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.

Blown head gasket. This appears to be a widespread issue amongst all 10th gen honda accords due to a poorly designed engine by Honda.

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.

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

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.

Driving in a construction zone. Two lane highway and my car immediately went into limp mode. Left me and my children stranded on the side of the road while semis and cars driving 65 mph went past very close to us. Honda knows these accords have head gasket issues and it is unsafe to be driving them.

Subject: Formal Complaint – Unresolved Safety Issues Following Recall Service (2018 Honda Accord) I am submitting a formal complaint regarding ongoing and unresolved safety issues with my 2018 Honda Accord, which began during the time frame of a fuel pump recall and have not been properly resolved despite multiple attempts with Honda service departments. Approximately two years ago, my vehicle was subject to a fuel pump recall. During the extended wait period for the replacement part, my vehicle began displaying multiple warning messages and experiencing performance issues. These issues included reduced acceleration and erratic driving behavior. Once the recall repair was completed, I was informed that an additional repair—a battery sensor replacement—was necessary, which cost approximately $800 out of pocket. Despite completing both the recall repair and the recommended sensor replacement, my vehicle has not operated properly since that time. Currently, the vehicle intermittently displays multiple system warnings, including but not limited to: - Emission system problem - Brake system and brake hold system problems - Electric power steering problem (reduced steering assist) - Vehicle stability and traction control warnings - Adaptive cruise control system problem - Collision mitigation braking system problem - Road departure mitigation system problem In addition, the vehicle frequently enters a reduced power or “limp mode,” making it difficult to accelerate safely, particular

Apparently, my car has a leaking head gasket. It was confirmed by the Honda Dealership. While driving it will go in limp mode and will no longer accelerate. I have to pull off to the side of the road, turn the car off, and back on just to get to where I'm going. It is causing my car to stutter really bad and we're constantly having to put coolant in it. This is a safety issue and will cost about $7000 to get fixed. The most recent time it did it, I was at a stop sign and starting to go to turn and my car just would no longer accelerate.

Infotainment center continually freezes. When it does, backup camera does not work. I have tried software updates but it has gotten worse. It is also very slow to reboot so again, no backup camera during that time.

The dashboard on the vehicle lights up with multiple error notifications. This puts the vehicle in limp mode. Indicates emissions errors, check engine, lane mitigation, brakes, control system. Per different customers this fault is being caused by either faulty fuel injector, miss fire, bad ignition coils, damage head gaskets, or turbo mechanism faulty. My vehicle has 70,000 miles and others in the chat have less miles that are having similar problems. Head gaskets should not fail so soon with proper maintenance. My obd2 scan code is miss fire which could Indicate faulty spark plugs, coil, injector or headgasket. For a vehicle at 70,000 miles this shouldn't happen. Vehicle has been maintained as the manufacturer recommendations
