FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I am reporting a recurring safety and mechanical issue with my 2018 Honda Accord 1.5T, which currently has approximately 128,900 miles. My vehicle has been experiencing shaking/rough operation and multiple warning lights while driving. Diagnostic scans have shown P0301 – Cylinder 1 Misfire and U0401-68. The ignition coils were replaced with original/OEM parts in an attempt to correct the issue. After the repair, the warning lights went away temporarily, but within several days the same warning lights and symptoms returned, and the vehicle again showed the P0301 cylinder 1 misfire code. I am concerned because the vehicle continues to shake and operate abnormally despite the repair. I have learned that Honda has addressed cylinder-head-gasket concerns involving certain 1.5L turbocharged Accord vehicles, which may cause engine misfires. However, I have not had my vehicle diagnosed with a defective head gasket, so I am not claiming that this is definitely the cause of my vehicle's problem. When I checked my VIN through NHTSA, it showed 0 unrepaired recalls. I am submitting this complaint so that NHTSA has a record of the recurring problem and can determine whether my vehicle's condition may be related to a broader safety defect affecting 2018 Honda Accord 1.5T vehicles. I am concerned about the possibility of the continued misfire causing loss of engine performance, loss of power, stalling, or otherwise making the vehicle unsafe to operate if the underlying problem worsens. I have photographs of the diagnostic scans documenting the codes and records showing the previous repair.

Since I purchased this car in 2022, the collision mitigation braking system has randomly engaged for no reason. This has happened multiple times over the years, day and night, when no other vehicle, road obstructions, or other factors warrant the system triggering.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Vehicle started flashing all lights on dashboard. I drove it for awhile and then it eventually went off. A few days later same lights came back on a car started misfiring. Was told by Honda that is was the Turbo that's going bad. Today is just cut off on me. Luckily there wasn't anyone behind me. I see a lot of people are having these same issues and a recall should be put out immediately.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
While driving home from work in my 2024 Honda Accord EX 1.5T, multiple warning lights suddenly came on on the dashboard. Shortly afterward, I began smelling a strong gasoline/fuel odor inside the passenger compartment. I stopped the vehicle and got out. I could also smell gasoline outside the vehicle. I opened the hood and the gasoline odor was still noticeable from the engine compartment. Because I was concerned about the safety of the vehicle, I went to the nearest O’Reilly Auto Parts and had the vehicle scanned. The diagnostic scan showed P0172 (Fuel System Too Rich, Bank 1), P0300 (Random/Multiple Cylinder Misfire), P0301 (Cylinder 1 Misfire), P0302 (Cylinder 2 Misfire), and P0303 (Cylinder 3 Misfire). The vehicle had approximately 82,063 miles at the time. The gasoline odor inside and outside the vehicle is especially concerning because of the potential risk of a fuel leak and fire. I checked my VIN for recalls and no open recall is currently listed for my vehicle. I am reporting this incident because I believe the fuel odor, rich fuel condition, multiple misfires, and dashboard warning lights may represent a safety-related fuel-system problem that should be investigated.

I own a 2019 Honda Accord Sport 1.5T. While operating my vehicle, multiple safety-system warnings appeared on the dashboard at the same time. The vehicle displayed “Brake Hold System Problem,” “Adaptive Cruise Control System Problem,” “Collision Mitigation Braking System Problem,” and “Road Departure Mitigation System Problem,” each instructing me to see my dealer. These warnings concerned me because they involved the braking system and several Honda Sensing safety systems simultaneously. I parked the vehicle and turned the engine off. When I restarted the vehicle, all of the warnings had disappeared and the dashboard appeared normal again, even though no repair had been performed. The vehicle has approximately 72,980 miles. I have photographs documenting the warnings while they were displayed. I am reporting this to NHTSA because the problem was intermittent and affected multiple braking and driver-assistance systems at the same time. I am concerned that the systems could malfunction again while driving, including the braking/collision-mitigation system. I would like this incident documented as a potential safety defect involving the 2019 Honda Accord.
NHTSA complaint #11762298 — an unverified report by a vehicle owner.
I own a 2018 Honda Accord Sport 2.0T that has been consistently maintained through authorized Honda dealerships. On July 30, 2026, at 135,968 miles, I took my vehicle to Nalley Honda for a Blind Spot Information System warning and maintenance. The dealership performed a multi-point inspection and documented the spark plugs, cooling-system hoses, and fluid leaks as PASSING. I authorized approximately $1,231 in repairs and maintenance. Only days and approximately 202 miles later, multiple warning lights appeared. I returned to the same dealership. At 136,170 miles, Honda documented DTC P0302 (Cylinder #2 Misfire). The injectors passed an air-fuel test. The technician then noted pressure releasing from the cooling system despite low coolant temperature. A head-gasket leak test was performed and FAILED. Honda diagnosed a blown cylinder head gasket and recommended approximately $4,906 in repairs, including spark plugs that had passed inspection only days earlier. I am concerned about the sudden failure of a major engine component in a well-maintained vehicle, particularly so soon after a Honda dealership inspection. I have learned that other Honda Accord 2.0T owners have reported premature head-gasket failures. A failed head gasket can result in misfires, coolant loss, overheating, reduced engine performance, and potential engine damage while driving. I am requesting that NHTSA review this complaint along with similar complaints involving Honda Accord 2.0T head-gasket failures to determine whether a defect trend exists and whether an investigation is warranted.

On August 29th 2026 at 1:28PM (13:28) 148,320 mi. on odometer During interstate driving and topping the Sunshine Skyway Bridge on Interstate 275 Northbound (27.617863, -82.653639) the vehicle detected both road departure and engaged the emergency automated braking due to the shadow generated by the superstructure of the Skyway Bridge falling on the road surface. The vehicle attempted to correct the "road departure" by steering the vehicle away from the perceived problem and violently engaged the brakes nearly causing a collision as it has done numerous times before. In this particular event, it was an extraordinarily dangerous situation given the location that it occurred (190ft in the air on a walled in 2 lane interstate highway). I have reported this to NHTSA and American Honda on multiple previous occasions and await a repair or even an acknowledgement of this extremely dangerous issue. Honda has opened a case on this but have had 12+ months and no response has been issued.

I purchased my 2018 Honda Accord Sport from CarMax on January 16, 2026, and I have had several serious problems with the vehicle since purchasing it. Every warning light on the dashboard has come on, my radar system will not stay calibrated, and I have been told that my fuel injectors need to be replaced. In addition, the relay module was already broken when I received the vehicle, which causes the interior lights in my car not to work properly. These issues have caused serious concerns about my safety and the safety of others because I cannot depend on the vehicle’s safety systems or know when another component may fail. The vehicle and affected components are available for inspection upon request. I have attempted to get these problems addressed, but I have not been able to get a satisfactory resolution. The issues have been identified/diagnosed, and I am seeking further inspection to determine the full extent of the problems. I have not had the vehicle inspected by the police or an insurance representative, but I am trying to get the manufacturer/dealer involved so these issues can be properly documented and addressed. I am especially concerned because I have only had this vehicle since January 16, 2026, and I have already put a significant amount of money into it while still owing a substantial amount on the loan. I was also informed that the vehicle could potentially be considered a total loss within the next couple of months. I do not believe it is reasonable for me to be left responsible for a vehicle that I recently purchased from CarMax and that has developed or revealed so many serious problems. I am requesting assistance in determining whether these issues can be properly repaired, whether the vehicle is safe and reliable to drive, and what options are available to me for a resolution given the amount of money I have already invested and the remaining balance on my vehicle loan.

I was driving on 42 at 2:05 a.m. And I was heading towards the exit to get off and I started slowing down and after I took my foot off the brake, the brake light illuminated on my dashboard for me to hit the break, like something was in front of me and there wasn’t anything in front of me.

I was driving on route 42 at 11:52 PM and my brake light illuminated on my dashboard indicating me to hit the brake so I stepped on the break so my car wouldn't brake itself. There was nothing directly in front of me for that like to come on but it did. The highway was dry there was a little bit of cars on the highway but in front of me
