| Mar 2026 | VEHICLE SPEED CONTROL,ENGINE,FUEL/PROPULSION SYSTEM | I started driving this vehicle and all of a sudden it started slowing down, and would not go up to speed. I had it fixed, the car started skipping, making a jerking movement while driving. I made an appointment with Tameron Honda of Birmingham on 3/26/26. As soon as I pulled up to Honda dealership the engine light was on. The company was trying to bill me 6100 dollars for fixing the car. I do not have that amount on hand and I need my car. I had to drive my car away from the dealership while it was in idle mode state into traffic the car moved so slowly that I could have wrecked. The dealership did not do their due diligence by going off of the vin number and making sure that the customer is safe with their brand. I was told that they did a full inspection at the dealership. I have been scared to drive this vehicle since the issue keeps happening. | Crash: No Fire: No | Unknown |
| Mar 2026 | ENGINE | Head gasket blown, apparently this has been a known problem with Honda, which they are refusing to repair, noting mine did not come from a specific factory. [XXX] 2018 ACCORD 1.5 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Mar 2026 | UNKNOWN OR OTHER,ENGINE | As soon as I got to work and put it in park I got a message on the dashboard saying “Engine Temperature Too Hot. Do Not Drive. Allow Engine To Cool”. No other warning signs were shown before this. I looked up on google what maybe it meant and to my findings it mentioned gasket and all I noticed recent complaints and claims filed with 2018 Honda accords for a known issue with these Honda accord sport 2018 models for blows gaskets. | Crash: No Fire: No | Unknown |
| Mar 2026 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | I own a 2018 Honda Accord equipped with Collision Mitigation Braking System (CMBS). The vehicle has experienced multiple instances of false collision warnings and phantom braking. The issue occasionally occurs when approaching overhead interstate signs. In most cases, the system flashes brake warnings briefly and then clears. However, on one occasion during rainy conditions a few years ago, the vehicle unexpectedly applied the brakes at highway speed with no obstacle present. The vehicle has undergone multiple camera calibrations (this may have also included the radar), but the problem persists. This creates a serious safety hazard, particularly at highway speeds where sudden braking could result in a rear-end collision. The issue appears to be related to false object detection by the ADAS system, potentially involving radar or sensor misinterpretation. | Crash: No Fire: No | Unknown |
| Mar 2026 | ENGINE | Almost all of the 1.5T engines (L15BE) are having head gasket issue where the gasket slowly fails over time resulting in slow coolant loss and at one point sudden overheating causing block and head warping die to design flaw ( groove in between the cylinders resulting in lack of effective and enough surface area for the head gasket to seal the combustion chambers). It has been confirmed by Honda techs and by average 100k to 140k, all engines are failing and the dealers are raking up $ 6k to 9k charge for each change or even having to need new engines half the time. This process of slow leak results in sudden loss of power at highway speeds or acceleration and causing extreme danger of getting hit and having accidents. Took vehicle to mechanic and confirmed coolant leak inside cylinder 4 and 3. | Crash: No Fire: No | Unknown |
| Mar 2026 | EXTERIOR LIGHTING,VISIBILITY/WIPER | I owned a 2018 Honda Accord,i got it new from the dealership so im the only owner of this vehicle. my headlights keep building condensations prematurely causing them to fail . I have already replaced multple headlights because of this . also when the bulbs go out honda made it where the bulbs can not be replaced at all. these headlights cost close to $1000 each plus 500 in labor to installed. theres should be a recall for this as its costing me soo much money . I hoping we must hold accountability to its highest level so consumer dont have suffer like this. Thank you so much for reading! | Crash: No Fire: No | Unknown |
| Mar 2026 | ENGINE | Major head gasket failure with no warning while pulling out onto a busy road. There is a major design flaw with the head gasket, no recalls or preventative notices from Honda whatsoever! My wife was put into a dangerous situation once the car went to limp mode with no warning while getting onto a busy road. Multiple lights on the dash lit up when the car entered limp mode. The car was immediately towed to a Honda dealership and was diagnosed with a blown head gasket. Service manager stated this is a VERY common occurrence and is indeed a design flaw. Car was fixed with no help from Honda for their faulty design $5100... | Crash: No Fire: No | Unknown |
| Mar 2026 | UNKNOWN OR OTHER | The AC system on my 2018 Honda Accord 2.0T stopped blowing cold air due to refrigerant leaks in both the AC condenser and AC evaporator. The condenser is covered under Honda's warranty extension (Service Bulletin 21-018) which acknowledges a manufacturing defect where R-1234yf refrigerant corrodes the condenser tube walls. The dealer confirmed the evaporator is also leaking from the same corrosion defect. The dealer states both must be repaired together because the system cannot hold refrigerant with a leaking evaporator. Honda corporate is refusing to cover the evaporator repair despite it being caused by the same known manufacturing defect. This is a systemic issue affecting 2018-2020 Accords and other Honda models using the same AC components and R-1234yf refrigerant. | Crash: No Fire: No | Unknown |
| Mar 2026 | ENGINE | While driving at highway speed, the engine suddenly stalled without warning, resulting in a complete loss of power. This created a dangerous situation as I was unable to maintain speed or safely maneuver with surrounding traffic. At the time of the incident, all electrical warning lights illuminated on the dashboard simultaneously. Prior to this event, there were no clear warnings indicating imminent failure. The vehicle was later diagnosed with a failed head gasket and turbocharger issues. The sudden engine stall while in motion presents a serious safety risk, particularly at highway speeds, as it increases the likelihood of a crash due to loss of propulsion and reduced driver control. This issue appears to have occurred unexpectedly and without adequate warning | Crash: No Fire: No | Unknown |
| Mar 2026 | ENGINE | Head gasket had to be changed out. I have seen multiple cars having the same issue with this model. The vehicle sputtered and would not let me drive above 40mph. It was a safety issue when I first had it and it occurred in the freeway. | Crash: No Fire: No | Unknown |
| Mar 2026 | ENGINE | Car was jerking when acceleration. Dealer inspected the vehicle and said the head gasket is blown. It overheated a day after Honda dealership fixed my water pump. | Crash: No Fire: No | Unknown |
| Mar 2026 | POWER TRAIN | Transmission started bucking at 50k miles, the problem has gotten substantially worse at 60k miles. Rough downshifting and upshifting in low gears. Will slam into gears 2-3 often 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 even after ATF type 2.0 fluid change following dealer procedure. 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. | Crash: No Fire: No | Unknown |

The vehicle lost automotive power and decelerated to 5 MPH. The contact was able to pull over safely. The engine light was illuminated. The vehicle was taken to the local dealer the next day, where it was diagnosed with a misfire in cylinders #2 and #3, a computer code malfunction, and a blown head gasket. The vehicle was partially repaired. The manufacturer was contacted and assisted with the cost of the repair. The manufacturer confirmed there was no warranty coverage on the vehicle. The failure mileage was approximately 118,000. | Crash: No Fire: No | 118,000 |
| Mar 2026 | POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM | Head gasket failed at 58k miles without overheating per assessment at honda dealership. Safety was affected by going into limp mode instantly turning left onto 55 mph 4 lane road, no warning lights prior going into limp mode. Brief misfire occurred prior to incident, (did not know at time because it did not seem significant and no warning light). Dealer reports multiple 2018 honda accord 1.5L head gasket and fuel injector failures. Unknown if manufacture would inspect. In addition fuel injector has completely failed and requires replacement per honda dealership assessment, this occurred after dealership repaired head gasket. Waiting for final repair invoice, can and will provide upon request | Crash: No Fire: No | Unknown |
| Mar 2026 | POWER TRAIN,ENGINE | My turbo and fuel injectors went out at the same time. It has been fixed, so I don't think it can be inspected My safety was put at risk. The car randomly went into limp mode on the interstate at high speeds and suddenly came to almost a complete stop Yes, it was inspected by a mechanic, everyone with a 2018 honda accords are having this issue Yes, it was inspected by a mechanic. No warning lamps or anything, just a blinking check engine light that appeared for the first time ever. | Crash: No Fire: No | Unknown |
| Mar 2026 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | Experiencing an ongoing issue where multiple warning lights appear on the dashboard at the same time. The lights include several safety and system warnings, making it look like many different systems in the vehicle are malfunctioning simultaneously. Even after repairs were made, the dashboard warning lights continue to stay on or return shortly after. It has become frustrating because the vehicle continues to show problems even when something has already been fixed. THIS IS A SAFETY CONCERN. How can we know if something is actually malfunctioning if codes are being thrown, constantly?? We also can’t use the safety features included with the vehicle when this is happening. Having so many warning lights on at once also creates concern about the reliability and safety of the vehicle, especially since several of the warnings relate to important systems such as braking, driver assistance features, and engine performance. Repairs aren’t helping and I’m seeing sooooo many other 2018 accord owners with the same issue, as has been documented with this site, NHTSA | Crash: No Fire: No | Unknown |
| Mar 2026 | ENGINE | I am submitting a claim regarding a major repair needed on my 2018 Honda Accord. The vehicle was recently diagnosed at an authorized Honda dealership, where technicians determined that the engine requires a head gasket repair. I was quoted approximately $7,000 for the repair. Based on the research I have done, premature head gasket failure appears to be a known and recurring issue reported by other owners of this model, often occurring around 100,000 miles or even sooner. This type of failure at this mileage is unexpected for a properly maintained vehicle and raises concern about a potential defect or design issue. Additionally, the vehicle showed no clear warning signs prior to the diagnosis. There were no dashboard warnings or indicators that would have alerted me to an imminent failure, which made it impossible to address the problem before significant damage occurred. Given the nature of the failure, the relatively low mileage for such a major engine issue, and the high repair cost quoted by the dealership, I am requesting that this matter be reviewed and that assistance or coverage for the repair be considered. | Crash: No Fire: No | Unknown |
| Mar 2026 | VEHICLE SPEED CONTROL,ENGINE,FUEL/PROPULSION SYSTEM | I took my accord into Snellville GA Honda dealer for fuel pump recall and the day I received it from the service department, it started to sputtter and engine shutdown. I took back 3 times and got a different answer each time. I believe the turbo charger may have been affected from the fuel pump being bad. The latest diagnostic says it has turbo under boost issue. | Crash: No Fire: No | Unknown |
| Mar 2026 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | While driving in a busy area with pedestrians and other vehicles, my car hard braked out of nowhere to a complete stop for no reason. I was nearly rear ended. The adaptive cruise control shuts off completely after 15 minutes in use. Says to take it to the nearest dealership. Turning off and restarting the car gets rid of the notification. | Crash: No Fire: No | Unknown |
| Mar 2026 | AIR BAGS | Error message "Supplemental Restraint System Problem. See Your Dealer." comes on everyday. I understand this is a Honda well known issue and they refuse to recall. | Crash: No Fire: No | Unknown |
| Mar 2026 | POWER TRAIN,VEHICLE SPEED CONTROL,ENGINE | After recent service from local honda dealership vehicle started to drive sluggish. Had all fluids changed and the coolant flushed when serviced at the dealership. The vehicle now displays several different alerts upon start up "Emissions systems failure" Brake system failure" Hill Assist failure" Power Steering failure". Vehicle was returned to dealership and it was determined the head gaskets need to be replaced due to coolant leaking. This vehicle has been maintained consistently with documentation and shouldn't have this type of failure with only 100k miles. Repairs are $4800 and this should definitely be investigated because this is common in Honda Accord model years 2018-2022. | Crash: No Fire: No | Unknown |
| Mar 2026 | ELECTRICAL SYSTEM | The contact owns a 2018 Honda Accord. The contact stated that while the vehicle was parked and starting the vehicle, several unknown warning lights became illuminated on the instrument panel. The steering wheel failed to move, and the power steering warning light illuminated, and the steering wheel functionality became limited. In another occurrence, while driving at an undisclosed speed, the vehicle stalled, and it shut off, but was able to restart. The vehicle was taken to a dealer and diagnosed with an electrical failure, but the vehicle was not repaired. The vehicle was taken to an independent mechanic, where the battery was replaced, and the sensor box was cleaned; however, the failure persisted. The manufacturer was notified of the failure. The approximate failure mileage was 110,000. | Crash: No Fire: No | 110,000 |
| Mar 2026 | POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM | A 2018 Honda Accord 1.5T developed an engine misfire, coolant loss, and reduced acceleration shortly after purchase from a dealership on 01/07/2026 (around 156,000 miles / 15,000). On 01/23/2026, during a Honda dealer inspection at about 157,255 miles, the technician noted misfires on startup, found the coolant overflow reservoir empty, pressure-tested the system, and confirmed coolant leaking into cylinders 3 and 4 from the head gasket. The dealer recommended head gasket replacement plus spark plugs, drive belt, and valve adjustment. I was told that continued driving could worsen the condition, leading to overheating and further engine damage. After that diagnosis, the vehicle’s drivability worsened, and it became unsafe to rely on due to misfires and loss of acceleration, especially on the highway. The selling dealership refused to assist, claiming the defect was not present at the time of sale; Honda America acknowledged the head gasket concern but denied a goodwill claim, citing the high cost of the issue and lack of NHTSA enforcement on this issue. An independent repair shop then provided a second inspection/estimate consistent with the same head-gasket repair scope. The vehicle and repair records are available for inspection. No crash or injury occurred, but the defect caused a sudden loss of power and overheating while driving; I was stuck on the highway on two occasions with my hazard lights on after acceleration completely halted. Warning symptoms (the engine light) only appeared when the car suddenly stopped accelerating. Two days after an around-5,000 headgasket repair, drivability problems and multiple dashboard warnings appeared, including turbo-related concerns; this concern is ongoing. | Crash: No Fire: No | Unknown |
