Power Train Problems of Honda Accord - part 1

Car lost power while driving and came to a slow stop, was unable to accelerate. This was dangerous and I was on a relatively busy street will a small shoulder. Car made no noises or gave any warnings prior to this issue. Car engine was eventually able to powered back on, engine light now shows, along with power system light.

I am reporting a safety concern involving my 2018 Honda Accord. I purchased my vehicle used in January 2024 at approximately 90,000 miles and have kept up with the recommended maintenance during my ownership. At approximately 120,000 miles, a Honda dealership diagnosed head-gasket failure with coolant intrusion involving cylinders 3 and 4. Before diagnosis, the vehicle experienced rising engine temperature while idling, coolant loss, jerking during acceleration, numerous warning lights, and severely reduced acceleration. The problem progressed to loss of power and stalling while driving and slowing/stopping, requiring me to place the vehicle in park and restart the engine to continue driving. The vehicle also developed unstable rpms and engine surging while in park. Honda performed a cooling-system pressure test and borescope inspection and confirmed coolant intrusion. Head-gasket replacement cost approximately $5,000. I contacted american Honda (case #16533411), but goodwill assistance was denied because the vehicle is outside warranty and Honda stated it had no Honda-dealership service history. I am reporting this because the head-gasket failure resulted in loss of propulsion and stalling while operating the vehicle, creating a serious safety concern.

Car shuts off at highway speeds and in stop and go traffic like it has a fuel delivery issue. Car sputters and then loses all power. I know there was a previous recall on this vehicle but I’m curious whether it was actually fixed on my car specifically.

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.

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.

A motor mount bolt sheared causing the engine to shift violently making the vehicle undrivable. The car was driving in a residential area traveling at a low rate of speed, making a right turn when it occurred. Had it happened on a highway, the result could have been catastrophic. The car was towed to the dealer where it was purchased. The dealer stated that since the vehicle was out of warranty, they would not make any exceptions. We have reported this to Honda corporate and are waiting for a response but felt that because of the safety concerns we should also report this to NHTSA. Here is a link to a video from the service department: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving my 2023 Honda Accord hybrid, the vehicle suddenly displayed multiple warning messages, including a check engine light, and immediately entered limp mode. Engine power was significantly reduced, making it difficult to accelerate and safely keep up with surrounding traffic. This unexpected loss of power created a potential safety hazard because the vehicle could not respond normally to throttle input. The vehicle was diagnosed by an authorized Honda dealership. The dealer confirmed diagnostic trouble code (dtc) p2101 and determined that the throttle body assembly had failed. The throttle body assembly and gasket were replaced, and a software update was also performed before the vehicle could be safely driven again. I paid approximately $670. 34 for the repair at the Honda dealership. After researching this issue, I found reports from other owners of recent Honda Accord hybrid vehicles experiencing similar p2101 throttle body failures resulting in limp mode. I am submitting this complaint because an unexpected throttle body failure that causes a vehicle to enter limp mode while driving may present a safety risk, especially if it occurs in traffic or during highway driving. I believe this issue should be reviewed to determine whether it affects additional vehicles.

The driver front left driveshaft inboard joint has started making noise when putting the car into drive, reverse, and taking off from a stop. The part is currently installed in the car and is not available for inspection. It has been inspected by an oem dealership and confirmed to have play in the driveshaft. It has not been inspected by anyone else. Upon research, I found NHTSA recall 20v769000 that concerns this exact issue. The inboard and outboard joints are rusting and is allowing moisture to get inside of the joint. My VIN did have the open recall in 2021. The vehicle was inspected by an oem dealer in March, 2021 for a clicking noise that I could not replicate at the time. The dealer confirmed that the recall inspection they did in March, 2021 was inspected, but the driveshafts were not replaced. The noise is now consistent and can be replicated.

Dashboard displayed multiple messages and icons/warnings. Steering wheel locked, acceleration was low, barely any power to drive. Engine running rough condition. Obd2 scanner p0302 and p0303 detected. Engine misfire. Honda dealership diagnosis car. Main concerns include a head gasket blown or crack. Coolant leaking into cylinder 2 and 3. Tie rod cracked. Pressure test low. The vehicle has no prior history of cylinder head removal or head gasket replacement. Vehicle has been properly maintained through consistent oil changes.

The contact owns a 2024 Honda Accord. The contact stated that while driving 50 mph, the instrument cluster lights illuminated. The message “emissions system power reduced – see dealer” was displayed. An unknown transmission message was displayed. The engine was not working properly. The message "pull over and turn off vehicle" was displayed. The contact pulled over for 10 minutes, restarted the vehicle, and continued to drive to the residence. The local dealer was contacted, and a service appointment was scheduled. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 75,000.

Blown head gasket. Engine lost power and forced me to pull over. The problem is well documented with this generation of Honda 1. 5t engines, Honda dealership confirmed problem and second opinion from independent shop also confirmed, citing they had another Honda with the same 1. 5t engine with the same blown head gasket issue. No clear warnings prior to event, all the dashboard lights flashed on when car lost power.

While driving my vehicle suddenly would not accelerate above 20 mph and warning lights all over the dash lit up (check engine, abs brake system, adaptive cruise control, vehicle stability, power steering, hill assist, and brake hold). I took it for a diagnostic, it gave a code for cylinder 3 misfire. I got a tune up the next day along with a fuel system cleaning just to be safe. After about 35 miles of driving I had the same issue 2 days after the tune up, this time no warning lights. I took it back to the shop and this time the spark plug in cylinder 4 was bad. I believe I am at the beginning of what many others have complained about with these same symptoms. This problem makes operation of my vehicle unsafe and uncertain, at any time this issue can kick in and now you are limping along at 20 mph while cars zoom all around you. While trying to get the vehicle to the shop I created traffic buildups and was almost hit multiple times due to the vehicles diminished acceleration.

The contact owns a 2013 Honda Accord. The stated that the vehicle was taken for the recall repair for NHTSA campaign number 25v422000 (power train). The contact stated that after the recall repair was completed, the vehicle was not apart of the recall. The dealer advised the the when alignment was not apart of the recall repair and would be at the owners expense. The manufacturer was notified of the issue and informed that the alignment was part of the recall. The contact stated that while driving after the repair, the vehicle began to swerve uncontrollably, the vehicle felt loose and an adjustment has to be made while driving to straighten the steering wheel. The vehicle was not returned again to the dealer however the vehicle was taken to an independent mechanic where it was diagnosed as being severely misaligned. The contact believed that the recall repair was not properly repaired. The approximate failure mileage was 50,965.

I can’t drive the car normal have to drive 60mph or under the radio went out and Honda can’t seem to figure out why so I can’t connect carplay. Myself and my kids are at risk due to the car randomly cutting off at any given time. I took it to Honda twice and my car has not been checked they constantly say they’re backed up but don’t have any rentals in stock. Can’t get the car inspection done because the lights are on. No they’re were none the light randomly popped up and said it was a camshaft sensor piece I got that change and the lights are still on. Took it to a mechanic to have it diagnosed and they’re stating it’s the turbo. Which is pretty annoying the car maintenance is don’t regularly and I’ve only had it for a year and a half.

Blown head gasket after multiple spark plug replacements for misfires.

Vehicle: 2019 Honda Accord sport 1. 5l VIN: [xxx] mileage: approximately 122,497 my vehicle experienced a cylinder head gasket failure accompanied by coolant intrusion into the engine cylinders, injector-related issues, fuel trim failures, and cylinder misfires as diagnosed by an authorized Honda dealership. Prior to diagnosis, the vehicle experienced engine performance concerns associated with the misfire condition. The dealership documented historical misfire events and coolant intrusion into the combustion chambers. I am submitting this complaint because I am concerned that injector-related issues, engine misfires, coolant intrusion, and cylinder head gasket failures may represent a recurring condition affecting similarly equipped vehicles. Engine misfires and coolant intrusion can potentially result in reduced engine performance, loss of power, unexpected vehicle behavior, or engine failure while the vehicle is being operated. I request that NHTSA review this issue and determine whether a broader investigation is warranted. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

All lights on head dash are on , all components are not working properly or effected because of this. (engine light brake light abs light tire light traction control light , sensors out all) while driving vechile reduces power does not operate randomly , have to pull over shut the car off and turn it back on. Has high vibrations lot of shaking, stauling. I have had it looked at with multiple shops and dealer . Everybody is playing a guessing game and can not pin point what exactly it is . Was told it was spark plugs and coils, alternator , fuel injectors. All have been repaired, and still have all lights on dash and still facing every problem listed after repairs. Been inspected by manufacturer. Say not been resolved was told if it wasn’t what was already fixed they don’t know and that this is very common right now . It first April 2026 (3) times. May 2 times 2026.

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.

The contact owns a 2012 Honda Accord. The contact stated that while driving approximately 30 mph and turning left onto a secondary road, the vehicle abruptly stopped in the middle of the road. The vehicle was pushed off to the shoulder of the road with help from other motorists who had stopped to aid. The vehicle was later towed to the local mechanic, who diagnosed the vehicle and determined that the front passenger’s side cv axle was fractured from corrosion. The cv axle and the rear brakes and rotors were replaced. The manufacturer was notified of the failure and informed the contact that the VIN was not included in NHTSA campaign number: 20v769000 (power train). The contact stated that the vehicle had experienced the failure listed in the recall. The local dealer was not contacted. The failure mileage was 100,000.

I was driving down the highway, and the dash started to flash a message about the vehicle being unsafe to drive, stop driving immediately, call dealer. I was able to stop and then turn left across traffic with limited power; and continued to make my way back to work thinking I could probably get to my parking lot. The dash continued to display warning lights, starting with brake failure, then parking brake failure, and then the whole series of possible failures. I continued to drive about one mile. I shut the power off an powered up twice thinking that might reset the sensors; but they continued to fail. As I continued to drive there was limited power to the throttle, and I eventually coasted through a red light and into my work parking lot where the vehicle shut down entirely, and eventually fully locked up (couldn't start or event put in neutral to push). I had the vehicle towed to back to the dealer, and they diagnosed the problem as a failed transmission cooler. Of note, I had purchased the vehicle brand new less than 3 weeks before this incident and the vehicle had less than 600 total miles on it. There were no prior signs of trouble or warning lights.

Cv axle broke without warning. Minimal safety risk, had to push the car across traffic to a parking lot. Had the vehicle towed to independent garage for repair.

I have a misfire and all the warning lights came on. This is due to Honda having the fuel pump recalled that has damaged all the fuel injectors. It took them almost a year to get the recall parts and now myself and a ton of others are now having to pay for these fuel injectors to have a car that doesn't stall and die on the road. Honda should have taken care of this knowing it damaged the fuel injectors.

Merging from a stop into traffic and suddenly a loud bang from under car and unable to accelerate. Able to move to shoulder while coasting. Failure was found to be the passenger side driveshaft. The cvt version of my car has an open recall, but mine is a manual. Seems like an attempt to carve out part of the recall to save a buck by Honda.

Head gasket failure was diagnosed by a certified dealer. The only symptom leading up to the failure was slight hesitation when starting the vehicle. Safety issues include sudden engine power loss, engine fire, overheating, and reduced visibility from thick white smoke, and the potential loss of steering or braking power.

The car has a blown head gasket at 72k miles the odometer. This seems to be a major problem with 2018-2022 Honda Accords with the 1. 5 turbo engine. It also has a bad fuel pump.

My fiancé was driving my 2018 Honda Accord when the vehicle suddenly jolted violently while accelerating up a bridge. Immediately afterward, multiple warning lights, including the check engine light, came on and the vehicle lost all power. Thankfully, she was able to coast down the bridge and pull into an empty parking lot. This was extremely dangerous because the vehicle lost power while being driven and could have caused a serious accident. After turning the vehicle off and restarting it, the car appeared to operate normally. Because the issue was intermittent, I initially suspected the battery. I had the battery tested multiple times, but it was fine. Since the problem continued, I took the vehicle to a Honda dealership. They diagnosed a blown head gasket and estimated the repair would cost approximately $6,000. The vehicle is only worth about $6,000, making the repair financially unreasonable. Apparently this is a known/common issue with 2018 Honda Accords. I requested Honda goodwill assistance, but Honda declined. I then took the vehicle to a second independent repair shop for another opinion. They advised that the head gasket needed for the vehicle was on back order and therefore could not provide a repair estimate. The fact that this replacement component is currently on back order is concerning and raises further questions about how frequently this repair is being needed. If Honda cannot keep enough replacement parts in stock to service affected vehicles, it further suggests that this may be a widespread issue that deserves additional investigation. The vehicle is available for inspection upon request and has been inspected by both a Honda dealership and an independent repair shop. I am extremely concerned that a vehicle can suddenly lose all power while being driven and that a repair for a known/common issue costs nearly the entire value of the car. I believe this issue warrants further investigation by Honda and consideration of a recall or assistance.

In Feb. 2026, I had a software recall service performed on my Honda Accord. Later that same day, a persistent error message appeared on my dash: software update not available see dealer. I contacted the dealer and they said sometimes that error message clears on its own and to wait and see. A few days later as I was leaving work, I turned my car on, put it in reverse and realized I had no propulsion or power steering. I put the car back in park and restarted it and drove it straight to the dealer where it sat for about three weeks as they tried to clear the error message. They were not able to reproduce the issue I reported with my car being on but without power. I picked up the car on 3/16/26. After leaving the dealership, it began sputtering and lurching. I could see on the powertrain display that the car was not communicating well between the engine and hybrid battery. I pulled into a parking lot and put the car in park and it began functioning normally. I called the dealer and they said to bring it back if that happened again. It has not. Tonight, I was pulling up to a red light when my car suddenly slammed on the brakes and displayed lane departure mitigation off. I attempted to restore that safety feature and realized my car had lost power. It did restore power and I was able to drive home, but I am terrified of my car since it engaged the braking system for no reason and disabled a safety feature plus losing power. During my car's time in the service department, it got a new can gateway module and telematics unit along with repeated attempts to make the software update glitch free to eliminate the persistent warning messages that had been displaying. Honda tech support was involved, and I have contacted Honda corporate with my concerns about the safety of my car but am waiting for a response. My perspective is the software recall update ruined my perfectly good car and I am worried I am going to lose power and get injured or worse.

Driving on the highway, my dashboard lit up like a christmas tree. Car started having white smoke at tail pipe. Check engine lit blink 5 times. Had 4 kids under 14 years old in car. Almost got hit trying to merge over. Turns out misfire cylinder 4. Head gasket. Only 81,000 miles. I have owed 5 months. Car currently at Honda, they want almost 4,400 to repair. But apparently, Honda is aware of these head gaskets going prematurely, in 1. 5 l. And has done nothing about it. I do not have the money to repair this car on top of how dangerous it was to be driving on the highway. When this happened.

Transmission started bucking at 50k miles, the problem has gotten substantially worse at 60k miles. Rough downshifting and upshifting in low gears. Will slam into gears 2-3 often and cause driver and passengers to lurch forward. Will cause very rough acceleration at times and causes a danger in traffic given the speed becomes unpredictable. Transmission does not know what gear to be in even after atf type 2. 0 fluid change following dealer procedure. This is putting me and other drivers at risk because I cannot control my speed when transmission is slamming in between gears. No warning lamps, undetected by cars tcu.

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.

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.

What component or system failed or malfunctioned, and is it available for inspection upon request? the turbo charger and the fuel pump how was your safety or the safety of others put at risk? both instances I was driving and car automatically started to decelerate while I was on the busy interstate. Has the problem been reproduced or confirmed by a dealer or independent service center? yes by a dealer has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no but Honda has been notified because there is currently a recall out for these issues that includes my year of vehicle but not my VIN. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? yes every system in the vehicle stated it was failing and engine light came on.

2020 Honda Accord sport 1. 5. Routine maintenance always done on time. At 108k turn my car on after a routine 45 minute drive an hour or so previous and all warning lights come on. Tpms, brake system problem, road dept system, emissions system. Dealer reports head gasket needs replaced and 3rd cylinder misfire, coolant leak etc. Quoted $5k to repair. Only 108k miles. Honda isn’t what it used to be. Quick search reveals the 10th gen Accords and civics suffer from early failure of this product routinely. Surely a known defect worthy of recall.

When driving home one night the dash board in the car all of a sudden hade a lot of warning lights come on. I brought it to my mechanic to have a look at it and he suggested to change the spark plugs and the coils which was done and he cleared the codes. About two days later I went to go to work and once again all the warning lights on the the dash board come on and it wouldn't drive over 5 mph. The mechanic went deeper into the problem he said it was cylinder # 3 that had a misfire and the fuel injectors needed to be changed which was done($1,000 later). A week went buy no lights on the dash came on but it has a rough start and when you get to about 40 mph the car starts to hastate to move. This time I brought it rick case Honda to have it looked at and they are telling me it is now the head gasket on cylinder # 3 has a hair line crack and needs to be changed ($7,400) to remove and replace the head gasket. This happened over multiple weeks between bowering cars waiting for parts. Now I have find a way to pay a $7,400 bill.
