general problems of the 2018 Honda Accord - part 1

Unknown. I was informed that my fuel pump is faulty and as a result my engine needs to be replaced.

Vehicle dashboard lights up with multiple warnings, power loss/limp mode in traffic and while driving. Dealership said it’s a very common problem but Honda refuses to make a recall. Technician says it is most likely caused by faulty fuel pump which is already recall that caused damage to the injectors.

While driving on a bridge at under 20 mph, the vehicle's head gasket failed, causing the engine to overheat and coolant to leak from within the engine. The vehicle threw diagnostic trouble code p2601 and immediately entered "limp mode," severely cutting engine power and vehicle speed. Because this happened on a bridge with no shoulder to safely pull over, the sudden loss of power created a serious safety hazard — the vehicle could not maintain a safe speed or keep pace with surrounding traffic, increasing the risk of being struck by other vehicles. The vehicle was taken to a tampa Honda (11000 n florida Ave), where the failure was confirmed to be a blown head gasket that allowed coolant to leak into the engine cylinders. The head gasket and related components were replaced at a cost of approximately $5,000 to restore the vehicle to safe operating condition. The failed component is no longer available for inspection in its failed state, as replacement was required to make the vehicle drivable. No dealer, manufacturer representative, police officer, or insurance adjuster has inspected the vehicle; only at tampa Honda facility that performed the repair diagnosed and confirmed the head gasket failure. Prior to this incident, no warning lamps or symptoms were noted — the p2601 code and limp mode activation occurred simultaneously with the sudden overheating and coolant loss, with no advance warning. This failure is consistent with a widely reported defect pattern among Honda vehicles with similar engines, where the head gasket fails prematurely and allows coolant to enter the cylinders. Honda has not issued a recall or acknowledged a manufacturing defect despite numerous consumer reports describing the same failure mode.

My Accord reported multiple warnings at engine start up (check engine light, warnings about cruise control, etc. ), and the engine ran rougher than normal. I immediately drove to a Honda dealer for service. The Honda dealer, checkered flag Honda of norfolk, virginia, diagnosed a blown head gasket in cylinder 2, which allowed all coolant to drain into the engine. They also indicated that fuel injectors and spark plugs were compromised and required replacement. The vehicle has approximately 75,000 miles, has received regular maintenance, and was operated in normal driving conditions.

Had in tank fuel pump replaced as recall stated. After 1 year went bad again. Honda refused to cover the repair. My car stalled on the interstate in traffic running around 50 to 60 mph.

It started with multiple lights glowing on my dash. Then progressively the car felt sluggish and ultimately while driving to church in July the car cut off while I was making a turn. Some kind gentleman pushed my car helping me get out the intersection.

I just paid $250 for diagnostic fee and Honda mentioned it’s a head gaskets failure ironically enough for my model it’s a world wide problem I just spent $2k on a turbo charger job on my car last month thinking that was the problem.

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.

A lot of warning sides are on the dash , has been coming on every since the mileage hit 100k.

My car keeps losing power suddenly! sometimes it has even started to stall while driving. Also the electrical menu has tons of errors and isn't working. There are several recalls on Honda Accords for the fuel pump and the vehicle assistance module but my VIN doesn't show up.

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.

At approximately 44,000 miles, multiple warning lights illuminated on the dashboard of my 2018 Honda Accord (1. 5l turbocharged engine), including brake system, electric power steering, and driver-assistance/collision-mitigation warnings, accompanied by a rough start and an engine misfire. I took the vehicle to an authorized Honda dealer, which performed a diagnostic scan and a borescope inspection. The dealer confirmed engine coolant leaking internally into cylinder 3, a confirmed cylinder 3 misfire (code p0303), and a low coolant reservoir, and advised that the vehicle was not safe to drive. The diagnostic scan also returned fault codes across multiple safety systems, including abs/vsa stability control, electric power steering, the electric brake booster (low-voltage power circuit fault), and the driver-assistance/collision-mitigation system. This is a head gasket failure allowing coolant to enter the cylinders — a failure mode widely reported on this engine — and it occurred at low mileage, creating a risk of engine misfire, stalling, and loss of power. No crash, fire, or injury has occurred. The dealer's repair order documenting these findings is available on request. I have reported this to the Honda corporate, and they are not responding and stalling the delivery or any update on the case. It has been 3 weeks, and it is causing prolonged inconvience and safety issue to me and my family.

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.

Unknown, all lights are showing on dash with "emissions systems problems power may be reduced see dealer. " after spark plug replacement about a month later raw gas smell, rough idling, and slight jerking continues.

I was traveling north on highway 55 in huntsville, al when I put the car in sport mode all of the error lights came on immediately. This has happened on several occasions. My passenger seat belt error always comes on. When I call about getting the recall fixed it could never be done because the dealer ships says the parts are not available.

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.

While driving the car it went in to limp mode, restricting the ability to maintain normal driving. It did this because the head gasket needs to replaced because coolant is leaking into # 3 cylinder. My wife and others were put at risk when she had to pull over in an area that was unsafe According to a summerville police officer who came to her aid and helped her get the car to a safe area.

My car is 2018 Accord 2. 0t the car just started jerking then I brought it to Honda they said head gasket replacement needed, my car was properly maintained and it still happened.

Blown head gasket after multiple spark plug replacements for misfires.

The head gasket failed. Dealer diagnostic was performed and they determined leak of coolant into cylinder number 3. All maintenance done on car. No reason to fail. Further internet search shows that the head gasket failure on the 2018 Accord 1. 5 turbo seems to be a common issue and therefore a manufacturer defect. Yes it is available upon request. When accelerating the car will stall and lose power. Merging on to the highway the car would not move faster than 20mph and could have caused vehicles behind me to hit me. Yes, the problem was identified and reproduced by the dealer. Yes, the vehicle was inspected and serviced but upon receiving vehicle back, problem remained. The only symptoms present was a rough cold start and intermittent rough idle. The check engine light appeared only once the loss of power occurred.

The engine stalled on the freeway. Has been having rough idles on cold start. Water gurgling/sloshing sounds coming from behind the dash on cold start. White, sweet smelling smoke periodically comes from the exhaust. Followed up with spark plug replacements. The vehicle still has all previous issues. Upon further inspection coolant reservoir is empty indicated a leak. No leaking fluid has been found. Suggests internal leaking. Issue is likely failing head gasket issue. Bissel v. American Honda CO. Has been suing over this issue. The head gasket is allowing coolant into the cylinders mixing with fuel causing misfires and stalling the engine. Extremely dangerous. Likely to cause accidents.

My car is having issues with the head gasket. My car check engine lights came on like a lit christmas tree with many warnings (emission system, brake system, departure, uphill and many other more). I took my car into capital Honda for a diagnostic on 5/4/26 and they informed that it was the head gasket that needs to be replaced. They are charging me $6000 to repair and do not have the funds to fix. Also I contacted Honda corporate since I read on google that I may qualify for the goodwill program and they said I didn’t qualify since I did not purchase warranty on the vehicle when I got it. I also do see that there is a lawsuit in place for this. I’ve kept up with my car maintenance and never had an issue till now. The car is running rough and it’s shaking a lot. It’s also loosing coolant from the reservoir.

Car keeps throwing cylinder 2 misfire, replaced all spark plugs, fuel indicators and still having issues. Think it’s the ecm/pcm is bad or there’s a bad connection.

While driving at highway speeds, the vehicle experienced a sudden jerking and a catastrophic loss of motive power (limp mode). Simultaneously, multiple safety systems failed, including the collision mitigation braking system (cmbs), adaptive cruise control, and road departure mitigation. The vehicle became a road hazard in active traffic. A certified Honda dealership technician inspected the vehicle and confirmed a premature head gasket failure with coolant intrusion into cylinders 2 and 3. The engine is non-drivable and the vehicle is at 84,000 miles. Despite the documented nature of this design defect and its current litigation, american Honda motor CO. Has denied any assistance. The vehicle also has an open safety recall (24-009) for a fuel pump failure which presents identical safety symptoms.

Pulling out in front of high speed traffic, engine went into safe mode with check engine light. Fortunately a car at high speed avoided rear ending my car. Upon evaluation, dtc code p0303 (cylinder 3 - misfire) was present. Coils and spark plugs were changed but car was still misfiring. Honda has a warranty for 150k/ 10 year on fuel injectors but this VIN was not on list based on Honda service department. The Honda service department evaluated and car has head gasket leak in cylinder 3. This is a widely known problem reported on many Honda owner websites and Honda service acknowledged it was an issue but is not a “recall” despite the potential safety risk on the road when car goes in to protect / shutdown mode. The nature of this issue occurring on a well maintained car with 147k miles that is 8 years old and not being a recall and a safety related item is being reported by me as me and my family could have been impacted by a rear end collision as car shut down / protect mode. This could and likely has occurred to other owners and possibly attributed to accidents and safety of passengers. Honda wants over $11k to repair the car which includes fuel injectors / plugs / coils / new head as they reflect old head can’t be used even if machined / head gasket. This issue is a safety related issue and should be a Honda recall as the head bolts are a known design issue causing premature failure of the head gasket. Submitting this to document my incident, protect the public driving this model and year and hopefully providing information to warrant a recall so that all repairs will be performed under recall warranty. Also to protect the public from a Honda Accord safety issue for 2018 Honda Accord lx.

In 2018 Honda Accord with the 1. 5-liter, four-cylinder turbo engine that had a head gasket fail at 110k miles which has been diagnosed and confirmed by local Honda dealer with misfire codes/counts on cylinder 1 due to coolant leaking inside cylinder 1 and 2 due to this bad head gasket. Due to the bad head gasket and coolant leaking into cylinders, this caused the fuel injectors to clog and fail. Creating rough idling and poor engine performance, which could cause car to stall at any point, creating a safety concern for those in the car if stalled/stuck on public roads. Additional discovery information found here of Honda America acknowledging the defect and encouraging dealerships to report this issue with incentives. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was driving down a 45mph street when my car shut down, complete power failure. Dashboard lit up with all kinds of warnings. It had to be towed to the nearest shop.

I just submitted a complaint but wanted to add that after my car lost all power on a 45mph road and went into limp mode it then was towed to the closest shop. I do have a warranty but when I called Honda they said it wasn't covered the shop I took it to charged me 4100 dollars for a blown head gasket which from researching it looks like this is happening to all 2018 Honda Accords this is low mileage and unacceptable , turns out after I called and told Honda they refused to pay because I had already had the shop look for the problem so I had to pay 4100 for an issue Honda clearly knows about this is unfair and Honda needs to fix this issue.

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.

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.

On June 13, 2025, the fuel pump was replaced due to a recall. After the fuel pump was replaced and, in particular, after reading the Honda forums for this car, all the warning lights in the instrument cluster came on. After my mechanic checked my car and, with his knowledge of this type of vehicle, he recommended replacing the fuel injectors at 86,000 miles. Honda recommends replacing the fuel injectors at 1000 k. In the forums, this is what owners of the 2018 Honda Accord are doing.

I am reporting a failed remedy for recall 24-009 (23v-858). Following the fuel pump recall, my 2018 Accord stalled in traffic on March 21. On March 24 upon starting my vehicle all warning lights were illuminated on the dashboard, millennium Honda admitted the o-ring was misinstalled. This error triggered codes p0172/p0176 less than twenty-four hours later. The dealer is forcing me to pay $425 for damage caused by their botched recall repair.

At 144000 miles all vehicle lights came on and vehicle engine would shake and vibrate. Computer said misfire on cylinder three. Changed spark plugs and coil. Problem still persisted. Mechanic recommended replacing fuel injectors so I did. After injectors were replaced all the lights came back on and the car runs worse. I believe its a blown head gasket now and the mechanic is testing the head this week.

Doors lock actuators problem the break so fast , fuel injector problem head gasket, break warning sistem problems.

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.
