2018 HONDA ACCORD Complaints

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

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.

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.

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.

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.

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.

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.

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.

Everytime I try to turn my wheel it’ll get stiff and the notification will pop up saying “electric power steering system” but then it’ll go back to normal and when I start the car it sounds like it doesn’t want to start at all and like the cords are trying to connect because they start making a ticking sound. I’ve had issues with electrical before to where the airbags and lane assist had to be fixed but the issues seems to keep circling back around. Something going on with the electrical in the car and I have only had it for about a year and a half.

The rear brakes on my 2018 Honda Accord Sport 1.5T (Six Speed Manual Transmission) have failed prematurely. This failure of the pads and rotors was confirmed, at the request of American Honda, by me at my local Honda dealer, and was documented in a response to American Honda. This occurred at 46,150 miles which i believe indicates a defective design in that the brake calipers, pads and rotors as a system were not built to the capacity needed to support Honda's design of this car that greatly increases the workload on the rear brakes. I am a very careful driver and minimize the use of brakes as a result. My calculation is that these brakes have failed at 1/4th the life that it would be reasonable to expect. The result is increased safety risk to car owners and drivers who do not act on this premature failure due to it not being normal or expected or affordable. Honda has effectively, through this brake design, implemented a need for car owners to enact a $750 repair on a frequency close to routine maintenance such as oil changes.
