2018 Honda Accord

What component or system failed or malfunctioned, and is it available for inspection upon request? I own a 2018 Honda Accord with approximately 132,000 miles. Shortly after my vehicle was serviced for the fuel pump recall, multiple warning lights and system failure messages appeared simultaneously. The affected systems include Road Departure Mitigation, Emission System, Adaptive Cruise Control, Auto High Beam, Collision Mitigation Braking System, Electric Power Steering, Vehicle Stability Assist, Tire Pressure Monitoring System, Hill Start Assist, and the Air Bag System. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? The failure of multiple safety and driver-assistance systems has created a significant safety risk. My vehicle is currently operating in limp mode, resulting in reduced performance and making it difficult to drive safely in traffic. The loss or malfunction of systems such as collision mitigation braking, power steering, vehicle stability assist, adaptive cruise control, and air bag monitoring increases the risk of an accident and could jeopardize the safety of both vehicle occupants and other motorists. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. I took the vehicle to a Honda dealership for diagnostic testing after the warning lights appeared. The dealer confirmed that multiple systems were reporting faults. I was advised that numerous components would need to be replaced at a substantial cost. Prior to the fuel pump recall service, I had not experienced any of these issues and the vehicle operated normally. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by a Honda dealership for diagnostic purposes. To my knowledge, it has not been inspected by Honda corporate, law enforcement, or insurance representatives. Were there any warning lamps, mes

Vehicle brought to Ocean Honda, Weymouth MA with complaint that HVAC system underperforming. Customer asked to replace condensor under warrany but Honda required full diagnostic ($135). Honda disclosed that 2/3 HVAC system had leaks, and known issues. Honda has a known issue with faulty and leaking AC condensers, heat exchange pipes, and evaporators. They reported this vehicle had leaking condensor and heat exchange pipe. Honda stated they can replace the the condenser under warranty, but not the heat exchange pipe or evaporators - even though they admit both are faulty and often require repair, replacement, and costly AC system recharge. The costly repairs (upwards of $1,800-$2,000+) are passed onto the customer. These failures are confirmed by dealer (Ocean Honda - Weymouth) and considered hazardous, but refusal to fix unless cost is absorbed by customer.

When going 55 mph car started leaching back and forth aggressively followed by loss of engine power. Car decelerated to a max of 20 mph and would not accelerate past that. This caused the potential of getting rear ended in traffic. When I took it to the mechanic, they told me that my first cylinder was misfiring and that my fuel injector was the issue. A warning light only came on after the car decelerated to a low speed.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? I purchased my 2018 Honda Accord in 2024, and in 2025, I experienced significant issues with the vehicle. During my visits to both Honda of Southaven and Honda of Tupelo, they indicated that the head gasket might be the problem, which is a known issue with this model. I believe the malfunction is related to this component, and I can confirm that it is available for inspection upon request. 2. How was your safety or the safety of others put at risk? The issues with my vehicle have directly endangered my safety and the safety of my children. While driving, the car started jerking unexpectedly and then cut off entirely on the highway, which could have resulted in a severe accident. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, I have visited Honda of Southaven and Honda of Tupelo over three times reporting these problems. Both dealerships acknowledged the issue, with one dealership stating it was likely the head gasket, which they mentioned seeing frequently with Honda vehicles. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? I have not had an inspection by the manufacturer or police. However, I have had my vehicle inspected by two authorized Honda dealerships, where they diagnosed the problem. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes, before the failure, there were multiple warning lights on the dashboard, which indicated that something was wrong with the vehicle. These symptoms began appearing shortly after I purchased the car in 2024, and they escalated over time leading up to my visits to the dealerships in 2025.

The Acoustic Vehicle Alert System (AVAS) stopped emitting sound for no apparent reason. On June 2nd, I took it to Honda service center, they said the speaker behind the front bumper needed to be replaced. I paid $699.56, only to discover that the AVAS still didn't work. I took it back, they said the accoustic unit needed to be replaced. I paid $707.57. On June 18th, they called me to pick up the car; I asked if the sound was working, they said the sound was there but it wasn't as audible as in other comparable cars. When I drove the car, I found a parking lot and drove below to 25 miles, even when the car was put in EV mode, I personally could not hear any noticeable sound even with the window open. I had contacted American Honda, and reported the issue, especially that the service centers didn't seem to know how to fix the issue. I requested from American Honda that they dispatch an egineer or provide the Honda service centers with directiond how to fix. Nothing happened. I'm not convinced that the AVAS was fixed. The design is faulty and many cars risk to be grounded because of that. The worse part was that the Honda service centers are not able to fix the issue. I just wasted $1,407.13 (plus the Uber rides) for nothing. Also, I don't understand why they held the car from June 2 until June 18th, and when I asked about the status, no meaningful update was given. This issue is likely to occur again with thounsands of hybrid cars.

On June 24th, 2026, I received a warning for "Supplemental Restraint System Problem". The airbag Dash indicator illuminated on the dash. The issue is intermittent and the warning has appeared on five separate occasions since. The message had went away when the vehicle has been turned off and has not appear every time the car is running. It does appear mid-travel on occasion. The issue is consistent with the passenger airbag sensor failure description recall that is associated with other VIN Numbers for the 2028 Accord but my VIN is not listed in the recall.

The Body Control Module of my 2018 Accord has failed. At 70,000 miles on my vehicle the door locks began to be unresponsive. At 100,000 Miles all door locks were unresponsive to the door control and fob control. The only way to secure my vehicle is to manually lock all doors and use the key within my fob to unlock the drivers door and then manually unlock all other doors. Ed Martin Honda in Indianapolis inspected the vehicle and determined the the Body Control Module would need to be replaced to make the Door locks work. There were known issues with the Body Control Module as there was an active recall for the software of the system. I completed the recalls software update at the time it was issued but this seems to be a continued problem.

My Engine is overheating, cannot drive the car at all. There is Coolant loss and leaking into the cylinder. It is Rough running and misfires: no matter when I start the Honda whether a fold start or not it is chunky and wants to give out. There is Loss of power which makes my car feel sluggish and is very dangerous as I’m driving myself, children and family on the freeways of St. Louis.

A loss of power while driving on the freeway created a dangerous situation and nearly caused an accident. The issue was diagnosed by the Honda dealer as a misfire of the 3rd cylinder due to a head gasket failure and a fuel injector issue. No other symptoms were detected as this appeared suddenly at the worst possible time.

I own a 2018 Honda Accord LX 1.5T. The vehicle has developed an intermittent hard-start condition after sitting overnight. The engine cranks for approximately 5–6 seconds before starting and runs very rough for the first 2–5 seconds before smoothing out. Warm restarts are normal. While driving, the vehicle hesitates and stumbles during acceleration, is slow to build RPM, and fuel economy has noticeably decreased. During one hard acceleration event, the vehicle lost power and the check engine light flashed. I also observed that if I turn the ignition on and allow the fuel pump to prime for several seconds before starting the engine, the vehicle starts noticeably quicker than if I start it immediately. This makes me concerned that the fuel system may not be maintaining proper fuel pressure after the vehicle sits. Because of the hard starting, hesitation, intermittent loss of power during acceleration, and the improvement after allowing the fuel pump to prime, I am submitting this complaint for investigation because these symptoms could create a safety risk when entering traffic or accelerating.

Crash

Head gasket failure, coolant leaking into cylinder 1 and 3. Car stuttering when try to accelerate and has trouble getting up to speed on highway. Coolant mixing with oil, rear main seal leak. It is available for inspection currently at dealership where it was diagnosed. My safety was jeopardized because I barely can accelerate on the highway causing cars to tail gate me and potentially crash into the back of me. The issue has been confirmed by Honda service department as a faulty head gasket. There were no warnings signs, no overheating nor any smoke indications of a faulty failing head gasket only stuttering at low spreads and not being able to accelerate. The problem first appeared a day or so before I brung it to Honda for a diagnosis. These are well none litigated issues with these head gaskets and are safety concerns that they’re failing to address.

The vehicle suffered a sudden, severe structural head gasket failure causing coolant to flood the combustion chambers. This results in violent engine stalling, limp mode, and complete loss of propulsion while driving at highway speeds, creating a severe traffic hazard. The manufacturer is actively tracking this conjoined cylinder failure but refusing to issue a safety recall for the defective engine block layout while their local dealerships dangerously misdiagnose the problem and leave customers with unreliable and unsafe vehicles.

At 157000 miles I am being forced to replace my fuel injectors and a blown head gasket on my 2018 Honda Accord. As I am sure you are aware, this is an ongoing issue with this model specifically, and yet no recalls have been issued. Please understand that this was a sudden failure as I had no signs there was an engine issue before being forced into limp mode while driving on the freeway. I also had my mother in the car when all of a sudden, my car could not go above 25 mph while in traffic. Thankfully we could pull over safely and were not hurt or killed. All the lights/warning messages on the dash became illuminated before finally settling on an “emissions problem.” All other warning symbols remained lit. My thermostat started to rise dangerously high especially while idling. I cannot stress how terrifying or dangerous this was. After a diagnostic last week at a Honda dealership, I was told I have a cylinder 3 misfire and that after they pressurized the system, they found a coolant leak which is due to the head gasket. I was also told my fuel injectors (which were just replaced in Sept. 2025) are already in need of replacement as well, but that I would only be charged parts for this repair as it would be included with the labor of having to tear down the engine. Despite this, I was still provided an estimate with the full cost of the fuel injectors as well at nearly $1600. My grand total for these repairs came to $6895. I was told at most it would be $6300 – not that that is much of a discount on an issue that should have been recalled. Again, this is a known design flaw and NOT a result of my neglect.

2018 Honda Accord EX-L with the 2.0L turbocharged engine. At approximately 113,000 miles the head gasket failed, allowing engine coolant to leak into cylinders 2 and 3. Symptoms included repeated cold-start engine misfires (diagnostic codes P0302, P0303, P0300), illuminated check-engine light, intermittent loss of power / limp mode, and gradual loss of coolant with no visible external leak. The failure was confirmed by an independent mechanic as a blown head gasket between cylinders 2 and 3. This matches a widely reported design defect in Honda's 1.5L and 2.0L turbocharged engines (2016–2022 Accord, Civic, CR-V, Acura RDX/TLX) that is the subject of federal class-action litigation. The sudden power loss this defect can cause while driving presents a safety risk. Repair cost approximately $6,000, paid out of pocket, with no recall in effect. Requesting NHTSA investigate a potential design defect and recall.

While on the highway, going approximately 60-65mph, lights on my dashboard suddenly lit up and turned right back off as my car began to decelerate on its own. After I was able to get my car off to the side of the highway, I had to have it towed home as it was inoperable. I had it towed to my preferred auto shop and they discovered the engine had failed at only 84,000 miles. The total cost was approximately $8,600. After a bit of research, it seems this is a known issue for this engine model from Honda and nothing has come of it so far.

Bad engine, and Honda knows it, and they will not fix my car. I have reported this to Honda America and Honda Japan. Cylinder 2 and the head gasket went bad at 77,000 miles. I am disabled and a full-time student. This was diagnosed at Honda Autonation in Columbus Ga. I even asked whether they would take it as a trade-in. They said no, so my next step is to file a class action lawsuit against Honda when they should have just accepted responsibility and fixed my car.

Two premature blown head gaskets and warped cylinder heads, the first at 95,000 miles, while driving on the freeway the car started to shake and all warnings lights came on, luckily I was not far from the dealership and took it right in. The second at 137,000 miles. The first repair was done at Honda of Concord dealership and was covered under the extended warranty. Warranty has since expired and the issue has happened again. This time Honda is recommending that I replace the engine, while denying my request for a goodwill repair. The dealership quoted me $10,000 for repair, and my car is maybe worth only $13,000. Honda knows that there's a design flaw with the 1.5L engines, but won't take any accountability for it.

Known issue by Honda; 2018 Honda Accord Sport, 1.5L 6S Manual Transmission. Head Gasket is blown, alongside failed fuel injectors for the 1.5L motor. Vehicle has been misfiring. Not accelerating properly which is causing the vehicle to suddenly slow down in traffic, promting potential vause for accidents. Almost was involved in 2 accidents due to the sudden and complete loss of power at a decent rate of speed. CEL came on twice, which then disappeared and the vehicle acted "normal" until acceleration. Took vehicle to a Honda Dealer and was told it was the "spark plugs and the coil packs", even after explaining to them that there was engine oil on the piston heads, and low coolant. Left the dealer upset that they barely did any diagnostic work, and took it to an independant shop that actually completed a proper diagnostic performance, and confirmed the head gasket is leaking coolant, and the fuel injectors are failing. Known common issue that Honda is failing to recognize.

There are 13 alerts showing on the instrument panel for various systems not functioning, along with accompanying yellow dash lights such as tire pressure, ABS, brake system, traction control, ACC, and LKAS. Systems not available include, ABS system, Adaptive Cruise Control, Road Departure Mitigation, Auto High-Beam, TPMS, Electric Power Steering, plus several others. These alerts first started January 2026 and occasionally would disappear; however, over the past few months the warnings have become constant. The vehicle has approx. 120,000 miles. Due to TPMS not functioning, I am not given a warning when a tire has gone flat/blown while driving as the tire pressure light is always on the dash. The only warning I am provided is the sound/smell of the rim dragging along the road to notify me the tire is flat. This poses a risk to myself and others by creating an emergent situation requiring me to pull over rapidly. Another incident occurred when ACC was enabled (at a time when the alerts had been appearing on and off). Cruise control set at 70 mph when suddenly the above mentioned alerts reappeared and ACC system became unavailable, leading to unexpected deceleration on the highway. This poses a risk to myself and others as it creates unpredictable driving patterns, unbeknownst to the driver. Initially I replaced the battery with no resolution of the issue. I later discovered maintenance code displayed by the vehicle was C003A-62 for Right Rear Wheel Speed Sensor Circuit Failure (circuit short to ground or open). The mechanic recommended replacing the right wheel hub assembly as this was suspected to be the cause of failed circuit. When that repair lasted no more than 10 mins before the warnings reappeared, the right rear wheel speed sensor itself was then replaced. Similarly, this did not fix the issue. I have not sought additional service due to repair costs beginning to add up with no resolution. Based on the history of reports, this issue does not seem uncommon.

On 2-252026 my wife and I were driving on highway I-15 in California when the car started to accelerate, decelerate and jerk and the engine light came on. It was very scary because we were on a major highway driving around 60 MPH and cars were behind us when the deceleration happened. We could have been hit by cars traveling behind us or either we could have caused a major accident. We had to get off the highway and have the car towed to Honda for assessment. There was no engine light warning or service warning from Honda prior to this happening, it just randomly happened. The car was repaired at a Honda dealership and they said there was a leaking head gasket on cylinder number 4. When we looked up information regarding this head gasket failure we saw that other Honda cars have had the same problem and Honda is currently involved in lawsuits regarding this leaking head gasket on cylinder number 4.

While driving on the highway at approximately 65 mph with my child in the vehicle during rush-hour on May 21, 2026, my 2018 Honda Accord Hybrid Touring (105,746 miles) suddenly dropped speed, and began backfiring and stopped responding to the gas pedal. The check engine light flashed and the vehicle ran rough. I activated emergency flashers and drove slowly to the shoulder. Sunnyvale Honda (Sunnyvale, CA) diagnosed coolant intrusion into one of the cylinders and head gasket failure. The vehicle had never overheated and showed no prior warning signs. All maintenance was performed at Honda dealerships per the maintenance minder schedule. The dealership performed a head gasket repair costing $7,500+ out of pocket. On the first highway drive after pickup, again with my children in the vehicle, the identical failure occurred: backfiring, complete loss of throttle response, vehicle unable to exceed 48 mph with the accelerator fully depressed. The repair did not resolve the defect. The vehicle is currently back at the dealership for further investigation. This failure created an immediate safety hazard on both occasions: sudden loss of speed on highway with no warning. Honda Customer Service denied goodwill assistance. I am aware of numerous similar complaints involving coolant leak and head gasket failure on 2018-2022 Accord including complaints documenting the same failure on the Accord Hybrid 2.0L engine. NHTSA should investigate this as a potential safety-related defect affecting multiple Honda engine variants.

I own a 2018 Honda Accord equipped with the 1.5L turbocharged engine. At approximately 53,666 miles, the vehicle developed a rough idle, engine shaking during startup, intermittent check engine light, and a cylinder 1 misfire code (P0301). I took the vehicle to a Honda dealership for diagnosis. The dealership confirmed coolant intrusion into cylinder #1 after performing a cooling system pressure test and borescope inspection. The dealership determined that the engine has a failed head gasket and provided a repair estimate exceeding $6,000. The dealership advised that the vehicle should not be driven because coolant entering the cylinder can cause further engine damage, loss of power, engine stalling, overheating, or complete engine failure while driving. I believe this is a safety concern because the engine may misfire, lose power, or fail unexpectedly during vehicle operation. A major engine failure at only 53,666 miles is not consistent with normal wear and tear. I am submitting this complaint so that NHTSA can investigate potential defects involving coolant intrusion, head gasket failure, and cylinder misfires in Honda Accord vehicles equipped with the 1.5L turbocharged engine.

I had a misfire on cylinder three. All vehicle lights came on. Vehicle had spark plugs and fuel injectors replaced. The problem persisted and the next code I received was a turbo burst under pressure code. So turbo and water pump were replaced. This made the problem worse because the new turbo made the head gasket leak. Now after paying $4000 in repairs I have to have the head gasket replaced for another $3000. This is a serious problem with these cars. Wish I never bought this piece of trash. I also replaced all break rotors pads and hoses. Terrible vehicle. Do not buy.

Side airbags deployed while driving for no reason/ no collision. Yes the car is available for inspection. The car was towed to a mechanic shop, while I was picked up by an ambulance. Yes my safety was put at risk as the airbags were deployed while car was in motion, knocking me out unconscious, leaving the car in motion possibly putting others at risk as well. I finally came to and was able to press the brake before any collision could happen. There were no warning signs prior. This incident caused me dizziness , headache , and with neck pain.
