2018 Honda Accord complaints

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.

See attached document for complaint.

I was driving and all the lights on the dash board came on. Including the engine light. I took the vehicle to the dealership service center and they said the turbo function of my engine was failing. and it was still covered under warranty so they fixed that. One day after the picking it up all the lights came back on. I took it back and they stated that the fuel injectors are failing thus causing engine misfires resulting in the engine light coming back on and the car randomly stalling or slowing. They indicated that the fuel injectors are NOT covered and repairs are around 2,400.00, I believe this should be covered because there was a previous recall on the fuel on the fuel pump (which is connected to the injectors). Also I don't understand how the "turbo" was still covered under warranty but the injectors are not. Upon doing my research this is a known problem on this make and model and Honda should correct the known defect.

I own a 2018 Honda Accord and have been 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. I have taken the vehicle to be serviced and attempted to fix the issues that were identified. However, 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 repaired. This situation makes it difficult to know whether there is a real safety issue occurring with the car or if the warning system itself is malfunctioning. 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. After researching the issue, I discovered that many other owners of the 2018 Honda Accord have reported experiencing the same problem with multiple dashboard warnings appearing at once. Because this appears to be a widespread issue, I am submitting this complaint so it can be documented and investigated further. I believe there may be an underlying defect causing these repeated warning lights despite repairs being made.

A 2018 Honda Accord suddenly displayed multiple dashboard warning messages at the same time after previously operating normally. The warnings include: Emission System Problem (avoid heavy acceleration), Tire Pressure Monitoring System (TPMS) problem, Brake System problem, Brake Hold System problem, Electric Power Steering system problem, Vehicle Stability Assist problem, Hill Start Assist problem, Adaptive Cruise Control system problem, Collision Mitigation Braking System problem, and Road Departure Mitigation System problem. These alerts appeared simultaneously when the vehicle was started, even though the car had been driven the night before without any issues. The vehicle still starts and runs, but the number of system warnings suggests a possible electrical, sensor, or control module issue affecting multiple vehicle systems.

Head Gasket Failure at 121,000. It has also affected the spark plugs. We were quoted a $4300+ repair at the Honda Dealership in Carlsbad. Engine displayed all lights and went on power loss mode and suddenly couldn't go more than 5-10 MPH, so we had to tow it. Was dangerous getting such a slow car into a parking lot safely.

Head Gasket caused multiple issues with coolant burning quickly. Multiple ignition coils also got damaged and had to be replaced. Though the underlying issue with the gasket was not addressed by the dealership. The head gasket is currently broken and does not function at all and the car has only driven 84000 miles.

Blown head gasket

All dash lights are on and the Honda dealership told me I have a blown head gasket, need a turbo replacement & fuel pump in which I wasn’t able to drive the car for 7 months at 112,276 miles..This seems like a known issue for this make and model vehicle after 100,000 miles

There are many warming lamps on in the car. My car won't pick up speed it in limp mode once I crank up. I have to turn it off and restart any order for it to go and pick up speed. My number 3 plug keep showing something wrong it has been replaced multiple times but still having the same issue. I had it checked out it's saying the same problem fuel. I have had my fuel pump change and still having problems. 2018 are bad models for honda and there should be multiple recalls because everyone having the same problems. Head gaskets,fuel injection, turbo problems as well as fuel pump

Wastegate actuator is no longer working and turbo on vehicle is no longer working as needed. My car currently has every warning light on the dashboard and fails to provide all advanced driver assistance systems that come with my vehicle making it unsafe. The problem has been addressed by Honda dealership service themselves as my code came back that it is a turbocharger wastegate sensor issue. Car has not been inspected by a manufacturer, police, insurance. All warning lights went off on car over two years ago from 2026.

My Honda is shifting harsh going into 5th gear and sometimes reverse is not available. I have taken the vehicle to the dealership and they are telling me I need a new transmission to the tune of $9,600. It only has 64,000 miles and the warranty recently expired. I took the car to another mechanic and he told me the same thing. There is no way that the transmission should go out at such low miles. Honda needs to step up and take care of this problem. There are many complaints about this issue but nothing is being done. I have the 7 year/100,00 mile warrany but the car is a 2018. This was the first year of the 10-speed transmission and many people are having problems. This needs to be addressed.

On February 26, 2025 I was driving my 2018 Honda Accord Sport (118,000 miles) with a 1.5t engine on a 55mph 2 lane roadway at approximately 55mph with 4-5 cars behind me when the engine suddenly went into "limp" mode and quickly decelerated to approximately 25 mph. I could see the cars behind me suddenly brake to avoid hitting me. I pull off on the shoulder, turned my car off and restarted. The car then drove normally to home. I took the car to the Honda dealer who diagnosed a blown head gasket. The sudden deceleration was caused by a misfire due to coolant entering the combustion chamber during the combustion cycle. The sudden deceleration almost caused an accident. When this happens the Accord does not warn the drivers behind with brake lights or flashers. I had the head gasket replaced at a cost of $4000+ The dealer's mechanic believes the cause is improper head bolt torque specs at the factory. Honda is aware of the a head gasket problem with the 2018-2020 Accord 1.5t engine, see Honda's NHTSA filings attached offering visa cards to mechanics who report head gasket failures, yet refuses to recall the engine or pay for replacing the head gasket unless under warranty. This is my 4th Accord (1985, 1986, 2007, 2018). I have never had any engine problems with my other three Accords. Honda needs to recall this engine and correct the head gasket problem so as to avoid unannounced, uncontrolled, and unintended deceleration at highway speeds due to going into limp mode (70-75 mph

It appears to be either the fuel pump or fuel injectors, at certain times of acceleration the car stops accelerating, the engine light blinks, I have to shut the car off and restart it. It seems like if I slow my car down then try to accelerate, like going through a roundabout or sitting in stop and go traffic really seems to set the problem off. I took it to a Honda dealership a couple years ago and they informed me it was fuel injectors but they were not in stock, they assured me the car was fine to drive, I called a couple times to ask if they had gotten the part, they sternly told me they would call me, anyways they never called me and it still happens, there is a recall out for other 2018 Honda Accords that seem to have a similar problem. All my lights are constantly on due to this problem, none of the features on my car work. Sometimes if I reset my battery the lights are fine for a while but the problem still persists. If I "Rev" my car up and gas it pretty hard when I immediately start driving it seems to help.

The high-pressure fuel pump on my 2018 Honda Accord failed even though the vehicle had previously been repaired under a recall for the same issue. While driving, multiple warning lights illuminated on the dashboard, including the check engine light and other system warnings. The vehicle began running rough and lost power, creating a dangerous driving condition, especially in traffic. This is the second occurrence of fuel system failure despite the recall repair being completed. The recurrence of this issue raises serious safety concerns, as sudden power loss or engine malfunction while driving increases the risk of an accident. The vehicle is currently not safe to drive due to the risk of stalling or loss of power. The problem appears to be related to the high-pressure fuel pump system that was previously addressed under recall.

I was driving on the interstate and suddenly I could no longer accelerate, my engine light started blinking and I had to pull over to a gas station as my car would not go above 25-30mph. I turned it off and back on and it work so I took it home. I took it to Honda’s the next day and after diagnosis they said that my head gasket was damaged causing coolant leaking into my engine cylinder and warping of the engine. They recommended an engine replacement. I never had any warning indications on my dashboard until then. I filed a case with American Honda to assist with repairs and it has been over two weeks without resolution. I no longer felt safe continuing to drive my car and I traded my car in for safety.

I have a blown head gasket which is a common problem with this vehicle. I have 85k miles. The car started to blow out smoke from the tailpipe which is very heavy.

My vehicle announced to me it has a Supplemental Restraint System Problem. See your dealer.

I wanted to report that this vehicle, according to Carfax, had 169,236 miles on August 15, 2025, and 9/4/25, and 85,326 miles on January 24, 2026. That's only 4 months! The odometer was tampered with, and this seller knew it was altered because it went through 5 different sellers in those 4 months. I don't know if their reports are true or false, which is why I'm writing to see if you can help me.

Engine Head gasket failure even after regular proper maintenance

I had to have $6400.00 worth of repairs (2018 Honda Accord Sport ) due to stalling & engine light came on and then it wouldn't go-due to the head gasket not being recalled and since they had the engine out, i also had to have other repairs they said were necessary plus car rental on top of that...I had only made my 2 car pymts when this happened!

Car initiated emergency auto break while traveling on the freeway at high speed (70 plus mph) in Phoenix, AZ for no reasons. There were no objects or cars within 500 feet, however I was approaching an overpass. This occurred multiple times on the freeway and on local roads. Reported to Honda, no fix.

The contact owns a 2018 Honda Accord. The contact stated that one of the tires was punctured by a nail, and after the tire was replaced, the check engine warning light and other unknown warning lights illuminated. The vehicle was taken to an Auto Zone, where it was diagnosed, and determined that there was a misfire in cylinder #2. The vehicle was then taken to a certified mechanic who replaced the cylinder, engine, ignition coil, and spark plug. After the vehicle was repaired, it was returned to Auto Zone to be diagnosed again. The contact was informed that there was a misfire in cylinder #2. The vehicle was returned to the mechanic, and it was confirmed that the spark plug in cylinder #2 was new. The contact continued driving the vehicle; however, a month later, several warning lights illuminated. The vehicle was taken to the dealer and was diagnosed with a misfire in cylinder #2. The dealer recommended replacing the fuel injectors and that an alignment of the radar was needed, and there was a failure with the transmission fluid, the CVT, and a software failure. The vehicle was not repaired. The vehicle was previously included in a recall for the failure; however, the recall repair was already performed. The manufacturer was not made aware of the failure. The failure mileage was unknown.

The car can't start because of the recall

My dashboard lite up like a Christmas tree. I took my car to Honda dealership. They put it on the diagnostic machine. A blown head gasket, Honda quoted me a repair price of $4400.

The cylinder head gasket on this vehicle has failed, causing engine coolant to leak into the combustion chambers (coolant intrusion). This has resulted in a recurring and dangerous loss of motive power that has put my safety and the safety of other motorists at risk on multiple occasions. Specifically, the vehicle has repeatedly entered "Limp Mode" while in active traffic, causing a sudden, drastic loss of acceleration that left me unable to maintain the flow of traffic or safely maneuver. This component failure is available for inspection upon request. The problem has been officially confirmed by Holman Honda of Fort Lauderdale, where technicians diagnosed the blown head gasket and confirmed the presence of coolant in the cylinders. The manufacturer's authorized dealership has inspected the vehicle and provided a formal repair estimate. Prior to the multiple "Limp Mode" failures, the vehicle exhibited clear warning symptoms starting in late 2025, including violent engine stuttering and a "shimmering" vibration during cold starts. Additionally, a distinct "gurgling" or bubbling sound was audible behind the dashboard, indicating combustion gases displacing coolant. During the actual failure events, the dashboard displayed a "Christmas Tree" effect of warning lamps, including "Emissions System Problem," "Brake System," and "Power Steering System" alerts, which disabled critical safety and driver-assist features while the vehicle was in motion. This persistent design defect has

I purchased this 2018 Honda Accord Sport brand new from the dealership, relying on Honda’s longstanding reputation for reliability and longevity. At approximately 120,000 miles, the vehicle suffered a blown head gasket during normal driving conditions. The vehicle has been properly maintained according to Honda’s recommended schedule. I have already opened a claim with Honda corporate regarding this issue and am currently awaiting their response. Despite proper maintenance, this catastrophic engine failure occurred, suggesting a design or manufacturing defect rather than misuse. This issue presents both a safety concern and a substantial financial burden, as I am a single mother of four who depends on this vehicle for daily transportation. Based on reports from other owners, this appears to be a widespread defect affecting 10th-generation Honda Accords with the 1.5L turbo engine, which I respectfully request NHTSA investigate.

Head gasket failure. Dealership did inspect vehicle and said this is a common issue. No warning prior to headgasket issue.

Sacramento ca , Car stopped in the middle of the highway couldn’t accelerate, won’t let me advance past 20 mph gas fuel was changed earlier in 2025 but I’m sure it’s the fuel injectors

My supplemental restraint system problem keeps appearing on my dash at random times, sometimes will go away then sometimes will stay for over a year. I have heard this is ongoing and Honda has not issued a recall.

After I took my car in for a fuel pump recall, it caused one of my injectors to be bad which will be 3000 dollars fix out of my pocket. this happened a few months after I took my car to the dealership, and it was doing fine before taken to the dealership for the recall. there are many other owners who reported they experienced the same thing, with all the dash lights came on but couldn’t find the exact cause until they replace their fuel injectors. First, all the alarms appeared, even the engine light was on but they would all go away after a few days. It had been on and off randomly for the past 4 months. the car is still driving fine but the alarms will pop up and stay for a few weeks to a month. It would randomly not letting me accelerate and slow me down, which if i was driving on the highway all the way in the left with traffic, that would cause a traffic jam and eventually an accident with other drivers.

The first time was at 93,000 miles where my car started to surge and went into limp mode but once I shut the car off and turned it back on everything went away and the car was fine. It did happen a couple more times, but as soon as I would shut the car off and turn it back on the code was cleared and by the time I got it to a mechanic there was no known code.This last time was at 220,000 miles I was just entering the freeway and once on the freeway, my car started to power surge really bad jolting me back-and-forth back-and-forth. This did not let me continue to finish reaching my highway rate of speed with cars coming up fast behind me nearly hitting me. Car continued to surge, and then went into limp mode and I had to pull over on the side of the freeway. I brought my car into Honda of San Bruno, California. They informed me after inspection that I had a cylinder three misfire due to a bad head gasket. They are receiving 3 to 4 of these a day and is a huge problem. I later found out that there’s a class action lawsuit for this head gasket failure that put me in danger and now has my car sitting in front of my house unable to drive.

Serval warning lights come on in my vehicle I’ve have seen this happen in other models of this car and nothing has fixed it. Car drives fine.

Transmission keeps malfunctioning from 1-2 and 2-3 gear shifts. Mainly prominent on the 2-3 gear shift having issues. Severe transmission jerk and sometimes slams into the next gear. This has been happening since I bought the car at 52k miles and it is currently at 62k miles. It can be available for inspection upon request. It also jerks on downshift. The transmission fluid has been drained and filled with Honda genuine atf 2.0 but the issue still persists after the service. The vehicle has not been inspected by the manufacturer. It has put my safety at risk because in low speed traffic my speed is unpredictable and I am worried of hitting a car in front of me. It is also an issue for vehicles behind me as well because the vehicle cannot find the gear and doesn't accelerate properly. When it slams into the next gear it seems to be a severe safety hazard for me and my passengers.

Headgasket seems to be forming a leak. Checked coolant today, zero leaks on coolant system but coolant was extremely low. It is sad to see that Honda has become so unreliable.

The vehicle experienced a catastrophic engine malfunction resulting in a no-start condition. The vehicle is currently inoperable and is available for inspection upon request. The engine failure caused the vehicle to lose power and become unreliable, creating a risk of breakdown while driving, which could have resulted in being stranded in traffic or an unsafe location and posed a risk to my personal safety and the safety of others. Yes. An independent repair facility confirmed the vehicle would not start and diagnosed the engine as failed. The vehicle was subsequently towed to another facility, where the condition was again documented. The vehicle has been inspected by independent repair facilities. The extended warranty company, Route 66, reviewed the claim and denied coverage based on their assessment. No inspection by the manufacturer or law enforcement has occurred. Prior to the failure, the vehicle exhibited warning indicators and operational issues, including overheating symptoms. These issues worsened over time and ultimately resulted in complete engine failure and a no-start condition.

Tachometer/speedometer screen completely black or dark. It will show the Honda logo and make sound. But once I’m driving or once the car is started it doesn’t show any rpm’s or the menu for miles, safety information or anything on that screen.

The vehicle experienced a rough idle and white smoke blowing out the exhaust on a cold startup. It did have coolant loss over a period of time with no visible leaks. I waited until I got a check engine code that revealed a misfire in cylinder 4. Upon further diagnostic testing it was revealed that the head gasket was blown between cylinders 3 and 4. I paid for the repair out of pocket only to see that this is a very common issue with the 1.5 turbo engine.

When I was accelerating the vehicle on 12/21/2025, a flashing check engine light came on, and the car started driving very roughly immediately, with an intense vibration. I noticed a lack of engine power, but the hybrid motor and battery kept me going for roughly 1 mile until they were depleted, after which I was unable to accelerate the vehicle. At that time, the car continued to decelerate, no matter how much I depressed the accelerator. I was able to safely pull over and turn the car off. I let it sit for one minute before turning it on again, at which point it behaved normally. I drove very cautiously to my destination, making sure to accelerate very gradually. This sudden lack of power put myself and others on the road at risk, as it was very sudden with no prior symptoms/warning lights, and I had no recourse besides pulling over as soon as possible. Over the next few days, I researched the problem online, and owners of Honda Accords from that generation (10th generation, model years 2018-2022) reported head gasket failure on all engines Honda offered the 10th generation Accord, including the 1.5 turbo, 2.0 turbo, and 2.0 hybrid engines. This problem is also reported on a slew of other Honda vehicles from roughly that time period. I brought it to Motor Werks Honda in Barrington, IL on 12/24/2025. After they completed their analysis, they determined it was a failed headgasket.

The A/C condenser on my Honda failed and leaked out all of the refrigerant, which subsequently caused the A/C compressor and related components to fail. This issue is well‑documented, and Honda has issued an extended warranty specifically for the condenser due to its known defect. My vehicle was inspected by an authorized Honda dealership, and they confirmed that the condenser failed and that the resulting loss of refrigerant caused the compressor to generate metal shavings. These metal particles can circulate through the HVAC system, potentially entering the cabin and posing a health risk to the driver and passengers. Despite the clear causal relationship and the dealership’s findings, Honda is refusing to replace the failed compressor and associated components, even though the failure originated from a part they acknowledge as defective and have extended warranty coverage for. There were no warning lights, messages, or symptoms prior to the failure. The A/C system stopped functioning without any advance indication, leaving me without proper ventilation and climate control. This defect raises both mechanical reliability concerns and potential health and safety risks due to metal contamination within the HVAC system. I am requesting that NHTSA investigate this issue further, as Honda’s refusal to cover the full scope of damage caused by their known defective condenser leaves consumers exposed to unnecessary safety hazards and significant repair costs.

Head gasket failed after car was fully serviced at authorized Honda dealer.It is a common issue with the 1.5t Honda engine.

Drivers seat belt not latching.

Blown head gasket at around 91,500 miles even though car have been kept up with oil change around 5,000k mile. It is currently in the mechanic shop as of 1/12/2025 awaiting repairs (parts are being order as we speak). So, probably can't have it inspected if requested unless it is soon. The random/early head gasket getting blown with not such high miles would have been devasting if I was driving on the highway. Since, it would cause the engine to over heat as the coolant is leaking into the engine piston and some case could cause lost of power on the highway. This problem seem to be quite common or expected as talking to the dealer and they were aware that a portion of these 1.5l turbo engine head gasket are getting blown. The vehicle or component has been inspected by an independent service center. I got misfire detected on cylinder 3 on 12/17/2025. I replace the sparks plug and it ran fine till 1/10/2026 when all of a sudden I can see the temperature gauge climbing. I stop driving the car that day on 1/10/2026. I check the coolant overflow reservoir on 1/11/2026 and found it strange that it was almost empty. I decide to take it to the mechanic on 1/12/2026 because I didn't see leaks anywhere and that was when they found the head gasket has failed and was slowly dripping coolant into the cylinder.

All dashboard lights are on & will not go away!

My car is having the head gasket issue which caused an issue while driving.

My 2018 Honda experienced a catastrophic engine failure (blown head gasket) at only 30,012 miles. A head gasket is not a wear item and should not fail at such low mileage. I previously reported related symptoms during dealer service visits in July 2024 and August 2025, including signs consistent with cooling or engine performance issues, prior to the complete failure. The vehicle has been properly maintained, has not been abused or modified, and shows no signs of neglect. Honda has denied goodwill assistance solely due to vehicle age, despite the extremely low mileage and premature nature of the failure. This appears to be a durability defect resulting in premature engine failure well below expected service life.

Blown Head Gasket, Coolant (possibly oil) leaking into combustion chamber. Confirmed by Honda of Kenner after getting Diagnostic. Car suddenly shook and temperature of car rose, misfires occurred shortly after with a flashing check engine light

Head gasket blown at 75500 miles. This appears to be an issue with the 1.5T engine in these cars, as reported several times and at issue in a class action lawsuit Bissell v. Honda.

My 2018 Honda Accord Touring with a 1.5L turbocharged engine began experiencing intermittent warning lights and error messages starting around 28,000 miles. I reported these issues to a Honda dealership on some visits however in most cases, the warnings were appearing and disappearing prior to my visit. However the error continued to appeared since then. At approximately 55,000 miles, multiple warning lights and error codes reappeared consistently. I took the vehicle to a Honda dealership for diagnosis and was informed that the issue may involve internal engine damage and that a full engine teardown would be required to determine the cause, at an estimated cost of approximately $2,000, before any actual repair could be identified. Seeking a second opinion, I took the vehicle to a different service location and completed a full tune-up at 63,000 including all standard maintenance expected at that mileage. Less than one week after the tune-up, the same warning lights and error codes returned. I took my car back to the same place where I had the tune-up completed and the same error codes appeared indicating the issue was not related to routine maintenance. I began to research online some common issues with my car, I became aware of a class action lawsuit (Bissell v. American Honda Motor Co., Inc.) describing a known defect in Honda 1.5L turbocharged engines where coolant leaks internally near the cylinder head, causing engine misfires, efficiency warnings, and internal engine da

My 2018 Honda accord had coolant leaking in cylinder 3. Which caused the head gasket to blow. My car stopped on me in the middle of the hwy. I took my car to a shop down here to get fixed he couldn’t get it to run. All dashboard lights are on.
