Power Train Problems of Honda Accord - part 1

While driving, the car’s engine suddenly shut off, and the brakes were barely responsive, making it extremely difficult to bring the vehicle to a complete stop despite continuously applying the brakes. This was a very serious and frightening safety issue that nearly caused me to crash into another vehicle or an object. I am very concerned about the safety and reliability of this vehicle and believe it needs to be inspected immediately.

I am submitting this complaint regarding two separate front drive shaft/axle failures involving my 2009 Honda Accord while living and driving in [xxx], a state specifically identified by american Honda as a "salt belt" state in connection with its xxx recalls involving corrosion-related front drive shaft breakage. The front passenger-side drive shaft/axle on my 2009 Honda Accord snapped in xxx. The driver-side front drive shaft/axle subsequently broke on xxx. These were two separate failures involving both front sides of my vehicle and created a serious and potentially dangerous loss of vehicle operation. I am particularly concerned because my fiancée has experienced nearly identical failures involving her 2010 Honda Accord while we have been living and driving in the same [xxx] conditions. The driver-side front drive shaft/axle on her vehicle snapped on xxx, and the passenger-side front drive shaft/axle subsequently snapped onxxx. Thus, between our two Honda Accords, both front drive shafts/axles on each vehicle have failed, resulting in four separate front drive shaft/axle failures across two vehicles in the same household. Our experience is also concerning in light of multiple publicly reported complaints involving 2009 and 2010 Honda Accords describing front axle, cv axle, or driveshaft failures, including reports attributing such failures to salt corrosion. We are attaching one such complaint involving a 2010 Honda Accord as a representative example. I recognize that another consumer's complaint does not, by itself, establish the cause of my vehicle's failures or prove the existence of a defect. Nevertheless, the existence of multiple similar reports involving these model years is significant when considered together with the two separate front drive shaft/axle failures involving my vehicle, the two similar failures involving my fiancée's 2010 Honda Accord, and american Honda's prior acknowledgment.

The head gasket failed in the engine. Coolant leaked into the cylinder head causing the engine to overheat and put the driver at danger to immediate vehicle failure while driving. The problem was confirmed by the dealer. The vehicle has only been inspected by the dealership. There were warning lamps that indicated engine overheating.

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.

There is a hole in the engine block and it happed while I was driving, people could’ve been hurt on the road because of this mechanical failure. Vehicle has only been inspected by a private mechanic who found the problem. There was no warning of this besides a add air to tire warning.

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.

My car currently has displayed all lights on panel. Went to auto zone to have codes read, shows powertrain-description is code po299 suggests turbocharger assembly. Safety is put at risk because all of the safety features are now disabled.

Different codes started blanking after I got gas June 11, 2026. Soon as I cranked up it started flashing warnings. Emission system, brake system, sport mode doesn’t work, cruise control doesn’t work, check engine light on, tire pressure light on. I took it to midlands Honda on June 15, 2026. They told me turbocharger and need spark plugs based off mileage. I took it to oreily, they say it only scan the engine light code which is turbocharger. Started a claim with Honda support and they denied me based off my mileage for goodwill credit. Said they contacted dealership and it’s not a manufacturer issue so I have to fix it out of pocket. Warranty expired. They kept calling me weekly until August 4, 2026 (when they told me they denied me). On August 12, 2026 my trunk won’t open. I contacted them back and they told me I have to pay for the diagnostic again (almost 200. 00) since it’s a separate issue. That’s crazy. It’s a whole group on social media where everybody having the same issue. Even some fixed the turbo and lights on dashboard still on. My turbo charger code can’t be the reason my trunk won’t open.

The car keeps giving me misfires.

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.

I am submitting this complaint regarding two separate front drive shaft/axle failures involving my 2010 Honda Accord while living and driving in [xxx], a state specifically identified by american Honda as a "salt belt" state in connection with its December 15, 2020 recalls involving corrosion-related front drive shaft breakage. The driver-side front drive shaft/axle on my 2010 Honda Accord snapped on xxx. The passenger-side front drive shaft/axle subsequently snapped on xxx. These were two separate failures involving both front sides of my vehicle and created a serious and potentially dangerous loss of vehicle operation.

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.

Car went into limp mode and was struggling to accelerate, went and got it diagnosed and was notified that my spark plugs needed to be replaced. Car began running fine but a few months went by and the issue came back. I was told I needed my spark plugs changed again. After the third time, I went and had my car diagnosed again and was told I needed a battery for the car because it was drained. Then I got the turbo replaced and still the issue remains. All lights on the dashboard are on, car overheats and goes into limp mode, sometimes not accelerating over 20 mph. My car went into limp mode on the highway, this scared me, so I haven't drove it since. Ive seen countless comments of users with the same make and model, experiencing the same issue. Its sad that Honda, known to be a trustworthy and reliable brand for years would do their customers like this, especially considering the state of the economy at the moment.

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.
