The turbo charger. The vehicle is currently at the dealership where it was made known that many other similar vehicles are experiencing this issue with no cause. The vehicle has been inspected by the dealer. This issues occurred 1 week ago. All the warning lights came up out of no where. Took it to two different places where they confirmed it was code P0299.

I have been having issues with my check engine light being on for about 6 months now. Took the car to Honda to get it diagnosed and was told that I needed to get spark plugs, fuel injectors, and ignition coils. Got all of that changed and the issues still remains. Had an outside mechanic take a look and he specializes in Hondas and was told that it is the head gasket, and that would be the only way the issue will get resolved. After taking the car to Honda 2 times and paying for diagnosis with the issue still there. I was getting on the interstate and my car just started stalling, had to immediately pull over before getting hit. I was quoted $3000 to have the head gasket done. This obviously is an ongoing issue with my model Hondas, and I am already out of pocket $1000 with the issue not even being resolved.

I have owned my Honda Accord for under a year, puchased around 100k miles. My head gasket blew at 118k miles. There was no overheating of the engine or warning lights before hand, my car was idling after work and I turned it on and then I had about 5 different warning lights on. I find out that it was a cylinder 2 misfire and took it to Joyce Koons Honda for them to inform me of a head gasket failure and quoted me for around $7,000.

Our mechanic, Buttons Auto in [XXX], diagnosed the loss of power, misfiring engine and anti freeze in the head cylnder # 3 with code P0304 and his conclusion was a blown head gasket. We took our car to the dealer, Mansfield Motor Group. Buttons also mentioned there was a pending class action suit against Honda for head gasket failure on our model with the1.5 liter motor. Mansfield Motor Group misdiagnosed the cars issue and charge us $2100 for the repair. A couple days after we got the car back the problems continued. We took it back to the dealer and they then diagnosed the isuue as head gasket failure. We spent another $4600 to fix the headgasket repair A total of $6100 we spent. We did file a claim with Honda, #XXX, which they denied both times. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am writing to formally lodge a complaint regarding a recurring issue I have experienced with the head gasket in my vehicle. I have owned several vehicles of this make and model, and I have observed a troubling pattern of blown head gaskets that has not been adequately addressed. Specifically, my current vehicle has suffered from this problem, resulting in significant inconvenience and additional repair costs. This issue appears to be prevalent across this year model as well, suggesting a potential design flaw or manufacturing defect that warrants further investigation. I respectfully someone to look into this matter to determine if a broader safety concern exists that needs to be addressed. Owners of vehicles affected by this issue may be at risk of serious engine damage and costly repairs. Thank you for your attention to this important issue. I look forward to your response.

The Honda Accord Infotainment system is constantly “ghost touching”. It will select buttons on the screen that I never touched. It is incredibly distracting as it happens while I’m driving and the screen changes rapidly. It also will turn off my GPS while I’m driving so I suddenly no longer no where I’m going. This problem began occurring when the screen was replaced by the dealership and I made them aware promptly but they said if I can’t reproduce it there’s nothing they can do, and this happens randomly. It happens without warning. It happens daily now at all times the car is on.

Head gasket seal broken, leading to coolant leak into the engine causing misfire

NHTSA ODI 11742005

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.

I have owned a handful of Honda's and never had an issue with them. I own a 2018 Honda Accord Sport and when driving it all the lights on the dashboard lit up. The car left like it was stalling and wouldnt go past 2nd gear. I was almost rear ended by a car and had my 2 granddaughters ages [XXX] and [XXX] in the back seat. I took it to Honda dealership and they said the turbocharger needed replacing as well as a head gasket. My sister inlaw also owns a Honda like mine but hers is a 2021 and the same issue happen to her. It seems like this is an on going problem that Honda needs to address or assist customers with purchasing. It is not safe to continue to keep these cars with these issues on the road.

Vehicle has only 48,037 miles. Diagnosed with bad cylinders 1 and 2 . Coolant also contaminated cylinders. I took vehicle to Autonation Honda Corpus Christi twice before the diagnosis. Vehicle was running rough. When first turn on engine especially when it is cold, there's a lot of engine shakes. Same as in when on idle. Technician said he could not duplicate problem but did not perform diagnostics. Vehicle was released. New coolant was added because Tech said it was low, brake fluids flushed, new sway bars were installed and wheel alignment performed. After a week, all engine lights came on while driving at 30 mph. Stopped the vehicle and get towed to the dealership. Diagnostics: blown head gasket, bad cylinders and needed new engine. Did a research and these were the Accord problems that were never addressed by Honda. Problems also included Turbos and Fuel injectors.

I am writing to file a formal complaint regarding my 2018 Honda Accord [VIN# [XXX] ] concerning what I believe to be a defective cylinder head or head gasket — an issue I have since learned is widely reported within the Honda owner community and is currently the subject of active class action litigation. Beginning at approximately 89,000 miles, my vehicle began experiencing episodes of engine rumbling followed by sudden shutoff. These episodes occurred two to three times before I brought the vehicle to an authorized Honda dealership at approximately 99,000–105,000 miles for diagnosis. At the dealership, I paid for a diagnostic inspection. I was informed that the technicians could not identify the root cause without performing a full engine pull and internal inspection, which they estimated would cost several thousand dollars — with an additional cost of $5,000–$8,000 if the diagnosis confirmed a cracked cylinder head or failed head gasket. Unable to absorb this expense, I did not authorize the repair. In an effort to keep the vehicle operational, I worked with independent mechanics and took the following corrective measures: replacement of spark plugs and ignition coils, replacement of the electric water pump, regular oil changes, maintenance of proper coolant levels, and avoidance of high or sudden acceleration. These measures allowed me to operate the vehicle for approximately one additional year without a recurrence of the shutoff events. Last summer, the vehicle failed to start entirely and could not be made operable. I was required to have it towed approximately 60 miles to its destination. The vehicle has not been operable since. Upon opening the hood, I observed coolant splashed across the engine cover consistent with a catastrophic head gasket failure. This failure occurred despite the vehicle being well maintained throughout my ownership. I believe this represents a known and systemic defect in Honda engine design for this model year.

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.

I own a 2018 Honda Accord with approximately 108,000 miles. My vehicle has experienced ongoing fuel system and drivability issues connected to the fuel pump recall. It took over two years for Honda to complete the recall repair due to delays and lack of available parts. During that time, my vehicle developed additional issues including failed fuel injectors that required replacement. Even after those repairs, the vehicle continues going into limp mode, causing loss of power and creating a serious safety concern while driving. When I brought the vehicle to Honda for diagnosis, I was charged approximately $180 just to scan the vehicle and then quoted nearly $4,000 in additional repairs. In addition, my vehicle experiences what many Honda owners refer to as the “Christmas lights” issue, where multiple warning lights suddenly illuminate across the dashboard at the same time. This appears to be a widespread complaint among owners of this model and is often associated with ongoing fuel system, electrical, or sensor-related problems. Honda vehicles are marketed as reliable, yet many owners of this model have reported similar problems related to the fuel system, injectors, limp mode, and dashboard warning light failures after the recall issues. I believe the prolonged delay in addressing the recall contributed to further damage to my vehicle. Honda should take responsibility for these known issues and provide assistance to affected customers.

The head gasket malfunctioned/ broke. It has been confirmed by the Honda dealer where I currently have my vehicle. There were no messages or symptoms prior to failure. My safety and others were put at risk because my vehicle began to turn off as I was driving up a hill with no warning. The vehicle began to decelerate.

Vehicle: 2018 Honda Accord On [XXX], at approximately [XXX] PM, I was driving on [XXX] [XXX] at approximately 35 mph. The weather was clear and the road was dry. A vehicle ahead of me began turning into [XXX] N. My vehicle’s Collision Mitigation Braking System / automatic emergency braking system activated suddenly. The system made an audible warning sound, displayed a warning icon, and applied braking even though I did not believe there was a crash-imminent situation. There were vehicles behind me at the time, so the unexpected braking created a potential rear-end collision risk. The braking event also caused back pain, and I later experienced some stomach discomfort. I am concerned this was a false activation of the automatic emergency braking / Collision Mitigation Braking System. I am also concerned because the system reactivates after the vehicle is restarted, meaning I cannot reliably prevent another unexpected braking event from occurring. I am requesting that this be documented as a vehicle safety concern involving possible false activation of the automatic emergency braking system.
