Engine And Engine Cooling Problems of Honda Accord - part 2

Why the 2019 Honda Accord turbocharger deserves a class action lawsuit many 2019 Honda Accord owners equipped with the 1. 5l or 2. 0l turbocharged engines have experienced serious and recurring issues with their turbochargers and related engine systems. These problems often appear prematurely and result in expensive repairs, performance loss, and potential safety risks — all of which suggest a manufacturing or design defect that Honda has failed to properly address. 1. Widespread turbocharger failures a large number of owners have reported: •turbocharger failure or malfunction well before 100,000 miles. •loss of engine power, whistling noises, or “limp mode” warnings. •excessive oil consumption and contamination caused by turbo seal leaks. These are not isolated incidents — they indicate a pattern of premature component failure. 2. Manufacturer awareness without proper remedy Honda has issued technical service bulletins (tsbs) acknowledging certain turbo-related problems, but no recall or extended warranty has been offered to cover affected owners. This shows awareness of the issue but a lack of full accountability. 3. Potential safety risk when the turbo fails, the vehicle can suddenly lose power — especially dangerous during highway driving or merging. This transforms a mechanical issue into a potential safety hazard. 4. Financial burden on owners turbocharger repairs can cost $2,000–$4,000+, often out of pocket since Honda claims these are not “defects. ” many drivers are left paying for repairs on vehicles that should not experience such failures this early. 5. Possible breach of warranty and consumer protection laws.

Coolant leak through the gasket into a cylinder so now I need a new head gasket. When I start my car, it starts to shake and don’t accelerate. I just got my turbo done in April because of the same issues.

The cylinder head gasket the vehicle heats up and causes us to pull over which impedes traffic the maker knows of said issue but has yet to address it a qualified mechanic has examined the vehicle and diagnosed the issue there was no warning.

Head gasket leak after replacing recalled fuel pump. Took my car in for safety recall on fuel pump, just 24 hrs later every check engine light came on and my vehicle slowed to a stop (car went into limp mode). This happened on a busy street with vehicles flying by. I had my vehicle towed to lancaster Honday (CA) where they did my safety recall the day before, they confirmed the head gasket leak. I had my vehicle diagnostics done at a different place as well and they confirmed the bad news, but also said this should not be happening to a new car with 66,000 miles. They advised I call corporate Honda and have them do a goodwill repair where the pay the repair since it is out of its 60,000 miles warranty. I had zero symptoms of this happening before it actually happened. I regularly had maintenance done on my car. I am very dissatisfied and disappointed that Honda just declined my goodwill repair after a month of waiting on them to “review the case”. I couldn’t be more sad and more screwed at this time. $5000 is not something I have right now to take care of something I shouldn’t have to. This is only happening to 1. 5 liter Hondas in my certain year range. I wanted a 2. 0 originally, but the dealership did not have any at the time so I am needing help. I will reach out to the ongoing pending lemon law case in CA to join the base and try to get my car fixed and have Honda do the right thing! I am not happy!.

Head casket issue caused the engine to go bad . . Every light on dash board is on.

Date of incident: [xxx] vehicle information: 2018 Honda Accord VIN: [xxx] incident location: north charleston, SC estimated vehicle mileage at incident: 78,000 miles on [xxx], while starting and driving my vehicle less than one mile, the engine would not accelerate above 10 mph. Following this, multiple service alerts illuminated on the dashboard. The vehicle was inoperable and had to be towed to hendrick Honda of charleston. The diagnosed issue is a leaking cylinder head gasket. This is the second major engine-related issue this year. In may 2025, I paid over $2,000 to repair a faulty fuel sensor injector. This current repair is estimated to cost over $5,000, bringing my total repair costs for this year to over $7,000 for a five-year-old vehicle with just 78,000 miles. This recurring pattern of significant and costly engine failures, particularly the cylinder head gasket leak, indicates a serious safety defect. It is not an isolated incident, as evidenced by publicly filed NHTSA complaints (11677717) for the same make, model, and year with similar engine failure issues at comparable mileage. The sudden loss of acceleration and inoperability pose a direct safety hazard. I am requesting an investigation into this defect and seeking full reimbursement for the recent and past repairs, totaling over $7,000. These are clearly not standard wear-and-tear issues and should be addressed by the manufacturer. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I own a 2018 Honda Accord with approximately 131,000 miles. The vehicle suffered a blown head gasket that my mechanic identified as originating from a known design or manufacturing defect in Honda’s 1. 5-liter turbocharged engine. They diagnosed the problem before they had my vehicle in their possession because they have already seen this so many times in other 2018 Honda Accords. The engine began showing symptoms such as coolant loss, rough idle, "christmas tree" engine lights, and an overheating warning light. There was no sign of external coolant leakage. A professional inspection confirmed head-gasket failure. I have maintained the vehicle According to Honda’s recommended service schedule and have documentation for all maintenance. I contacted my local Honda dealership and Honda’s customer service department seeking goodwill or warranty assistance. Despite multiple attempts and escalation to a “warranty specialist,” Honda denied coverage and refused to contribute to repairs. The repair estimate exceeds $5,700, which is unacceptable for a vehicle with regular maintenance and a known pattern of premature engine failures. Online owner forums and public databases show many other reports of the same issue. I believe this defect poses a safety concern, as overheating or sudden engine failure can occur while driving, creating risk of loss of power, stalling, or fire. I am requesting that NHTSA investigate the widespread head-gasket and engine failures on late-model Honda vehicles equipped with this engine to determine whether a recall or manufacturer accountability action is warranted.

While driving my 2019 Honda Accord, the engine began misfiring and losing power. A diagnostic scan showed misfire codes (p0300–p030x). The issue was traced to coolant leaking into the combustion cylinder due to a head gasket defect. This caused engine hesitation, reduced acceleration, and risk of stalling while in traffic. I have learned that Honda has issued a technical service bulletin (TSB) for this issue, but no recall. This is a serious safety concern because loss of power or stalling could cause an accident, especially at highway speeds or during turns/intersections. The repair is extremely costly for owners, and the defect appears to be widespread in 2018–2019 Accord models with the 1. 5l turbo engine. This should be investigated and addressed as a recall to protect drivers.

Recently bought this car a month ago. I started having problems with acceleration, as if the car was “bucking” every time I would press the gas normally at a red light or stop sign, accelerating from a stop. The vehicle wouldn’t make it up a hill while accelerating it was very hard bucking. I tried pressing the gas a little harder and the check engine light flashed and the car went into limp mode so I had to pull over. Made it back home and I was driving normally and every light you can imagine came up on the dash. I’ve heard from many others with the Accord they’ve had the same problems but once they get it fixed the problems keep happening or the vehicle blows up. I just paid full in cash for this car and my total is fix it is already at 5k to fix.

Head gasket between cylinders 2 and 3 blown, despite regular maintenance being completed by Honda dealerships. This issue has caused vehicle to go into "limp mode" while on the highway leading to safety concerns. This problem has been confirmed by not only a Honda dealer repair shop but also an independent repair shop and owners. There were not warning prior to the failure. Per the dealership, this is not something that could be caught during regular maintenance and inspections.

Car stalled/went into limp mode in the middle of turning onto a busy road almost hit by oncoming traffic. Check engine light came on, as well as all other warnings. Ran diagnostics and show fuel running lean and cyl 2 misfire. Checked all other possible issues related to codes and all signs point to bad fuel injectors.

Vehicle information: make/model/year: 2019 Honda Accord VIN: [xxx] mileage at time of issue: ~70,000 miles engine: 1. 5l turbo (if different, update before submitting) dealership: capitol Honda san jose, California complaint summary: engine misfire, rough running, and head gasket failure allowing coolant into cylinders. Details of the problem: at around 70,000 miles, my 2019 Honda Accord began running rough and misfiring. Our independent mechanic scanned the vehicle and found failure codes for cylinders 2 and 3. The spark plugs and ignition coils were replaced, but the car continued to run poorly and the misfires persisted. We then took the vehicle to capitol Honda in san jose, CA. The dealership performed a diagnostic inspection and a borescope test, confirming coolant intrusion in the combustion chambers. They diagnosed the vehicle with a blown head gasket, noting visible coolant in cylinders 2 and 3. This car has been carefully maintained, never overheated, and serviced on schedule. Head gasket failure at this relatively low mileage is abnormal and appears consistent with defects reported by other Honda owners involving turbocharged 1. 5l engines. This condition can cause rough idling, loss of power, and potential engine stalling, creating a safety risk while driving. Repair costs are significant and may indicate a systemic defect in this engine design. Requested action: please investigate head gasket and coolant intrusion failures in 2018–2022 Honda Accord models, especially those with the 1. 5l turbo engine, as this issue appears to be increasingly common and poses a risk of sudden engine failure. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The engine head gasket failed due to design flows. I have to put coolants and oil on a daily basis to keep the car running to avoid overheating.

The head gaskets are known to fail on the 10 generation Accord. It failed on my 2021 Honda Accord ex-l. I left work and while I was driving the dashboard lit up with every possible light. This was quickly followed by the vehicle losing power on the highway. I ultimately got it repaired by a Honda certified mechanic. The mechanic took it to a Honda dealer to confirm it was the gasket, in which it was. There were no warning lamps message or other symptoms prior to the failure. At the time of power loss I was on an 8 lane highway at 70mph. Luckily no accidents occurred, but the failure definitely put my safety at risk along with others. The mechanic I took my vehicle to has all available information if needed upon request.

On August 25th 2025 we were driving the vehicle on the freeway at 55 mph and upon acceleration the vehicle started to decelerate and the check engine light came on. The vehicle would not go over 10 mph at this point. We took it to the dealership to have the issue addressed. They told us that the issue was a misfire in cylinder #3. They told us the vehicle will need to relearn the firing order and for the next 2 weeks the vehicle was rough idling upon startup. We called the dealership to make an appointment to have that issue addressed and took the vehicle back to the dealership. On September 10 we were told by the dealership the head gasket is blown. We were told that they are seeing that this is becoming a more common issue with the engine of this year model vehicle.

Upon commuting to work, the car failed to accelerate causing the car to almost suddenly stop while driving; at the same time of the failure warning lights and beeping occurred. No warnings prior to failure. By god’s grace, I was not yet on the expressway and avoided what would have been a horrible accident jeopardizing not only my life but the lives of anyone that would have been behind me. The gasket failed (cylinder #3) and is available for inspection upon request. It was a significant safety issue as the failure occurred without warning causing the car to stop no warning. Yes, the dealer has confirmed the failure and I was quoted a $5800 repair cost in spite of a owning a lifetime power train warranty. No, the vehicle or component has not been inspected by the manufacturer, police, or insurance. I did place a call to american Honda and we were given a case #15822812 (but this case has since been closed without action. ) no warnings occurred before the failure. (beeping and messages occurred at the time of failure. ) had the failure occurred at a high rate of speed, on an expressway, loss of life could have occurred and no one would know what caused the accident since cars are usually towed away and declared “totaled. ” fortunately, I was on a road of 35mph but in just a few more minutes would have been at a speed of 65mph. There is a further safety concern that the dealer admits that there is a known problem with the oem component but plans to continue to replace with the same product. Note: this car has a superior care record and only 110,000 miles which means the failure is likely to occur again with the same parts. Internet searches are confirming this is a known product failure with no recall.

This vehicle has the same 3. 5 litre v-6 that is being recalled engine failures, and stalling in the Honda ridgeline, passport and acuras. Why arent the Honda Accords included? since 2020, this car stops moving forward, and attempts to stall after a complete stop in traffic. I have to feather the gas pedal to reingage the engine, and get the car out of danger. It is an ongoing situation. I am the only driver of the car, and would never letanyone else drive it, due to this. I happens very regularly.

My car ran hot for the first time and I was told my head gaskets were blown and I needed a new radiator. Once I got that repaired I was then told my transmission cooler went bad on my car which caused my engine to run hot and blow my gaskets in addition to cracking my radiator. I keep my car serviced as required with the Honda dealership and they had advised seeing this same issue in several other vehicles like mine. My car has less than 100k miles and I am the only owner. It has never given me any warning lights. The techs feel this is a manufacturer defect as my car should not be having this type of issue this soon. That’s the benefit of a Honda as I have owned several new Hondas and have never had any issues. I have done research and there are several forms with this same issue reported. I am attaching the initial work order. I was just advised of the transmission issue on Monday.

The contact owns a 2018 Honda Accord. The contact stated that occasionally, while driving at various speeds, the vehicle jerked and the engine lost compression. The check engine warning light was occasionally illuminated. The vehicle was taken to a local dealer, where it was diagnosed, and determined that the spark plugs needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was towed back to the same local dealer where it was diagnosed with a blown head gasket. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 112,000.

My car is always having some electrical issue but when I type in my VIN number, no recalls are listed under my VIN number and then for the last couple of days I've been experiencing acceleration problems when I look up a 2018 Honda Accord it is saying that fuel pumps have been an issue, but my VIN number pulls up no information as far as me falling under that recall what are the proper steps to get my car looked at to see if my VIN number even though it's not populating, any recall falls under the recall.

I attempted to start my vehicle's engine normally and the engine made a rough cranking sounded and then finally started. The dashboard displayed multiple warning messages immediately after: emission system problem/avoid heavy acceleration and high speed/see your dealer, tire pressure monitor system problem/check tire pressure/see your dealer, brake system problem/brake performance may be reduced/see your dealer, brake hold system problem/apply brake when stopped/see your dealer, electric power steering system problem/steering assist reduced/see your dealer, vehicle stability assist system problem/reduced traction and handling/see your dealer, hill start assist problem/vehicle may roll upon brake release/see your dealer, adaptive cruise control system problem/see your dealer, collision mitigation braking system problem/see your dealer, road departure mitigation system problem/see your dealer. I was able to carefully drive and drop off the vehicle at the dealership. The dealership conducted an inspection and found "the check engine light was illuminated due to a misfire in cylinder two. The diagnosis has revealed that this is caused by a bad head gasket, which is allowing a small coolant leak into the cylinder. To address this issue, the technician is recommending the replacement of the cylinder head gasket and spark plugs. Additionally, the technician has noted that the fuel injectors are a known failure point and suggest replacing them as well while the work is being performed. " also, the service employee told me verbally that this is a common issue with the Honda 1. 5 turbo engines and they see this all the time. I authorized the replacement of the cylinder head gasket and spark plus since the cost was covered under my existing powertrain warranty with Honda. After a week, the vehicle was released to me and working fine. My safety and the safety of others with a similar engine was put at risk due to no prior warning and the impairment of critical safety systems.

Car went into limp mode, immediately brought to a Honda dealership. Planet Honda in NJ. Misfire in cylinder 3. Causation of misfire was a defect head gasket allowing coolant to flow into cylinder 3 causing a vehicle shut down and $3625 in repair costs. Warranty covered it but I have heard many other cases with this have not.

While driving the car, the oil light came on and the engine died. Losing vehicle power while driving poses a very serious safety risk. After taking it to a Honda dealership, the mechanic diagnosed the following issue: "head gasket has failed causing coolant to leak into cylinder 3".

At approximately [xxx]. Pacific, I was traveling southbound in the fastrak lane of the [xxx] departing from pleasant hill, California headed to pleasanton, California. As I began to accelerate, the engine began to sputter. Immediately, the check engine light flashed on, then the dashboard reported a number of issues ranging from brake failure, tpms failure, power assisted steering failure, vehicle stability assist failure and a number of other issues that I have never encountered since purchasing the vehicle. The sudden deceleration almost resulted in other cars impacting my car as this occurred during the morning commute. I was able to safely navigate off of the freeway. I was on speakerphone with Honda when this occurred. Had I not acted swiftly, a potential high speed rear end collision was likely to have occurred. I immediately took the car to concord Honda. The team at concord Honda performed a diagnosis and advised me that my head gasket was leaking water into the combustion chamber which resulted in the sudden loss of power. I was and continue to be dissatisfied with the handling of this issue by Honda as my car has never been handled by another mechanic. My car has a perfect or near perfect maintenance record and should not have a blown head gasket at 80k miles especially since my car is meticulously maintained and serviced by concord Honda. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Five times the past year, while driving on the freeway, the first incident I cannot remember, but I do know that the other four incidents were on a slight incline. The car acted as if it wasn’t getting enough gas and slowed down and was shaking. Giving gas would not help, and it kept slowing down. The check engine light would come on and once I turned off the car and turned it back on, the car acted normal again. Sometimes I had to keep it turned off at least a minute before it would run normal again. I took it to the dealership twice and both times I was told that because the engine light was not on, they did not know what was wrong. I asked if they could check the computer to look for faults, and they said that is a waste of time because not only would I have to pay for the service,but they could guarantee that faults will not be found so it would be a waste of my money. The fact that this has happened so many times. , once every a few months, and the fact that there has been similar problems on other models/years, I would like to report that I think it also has to do with my model and year. While filling out this report, it only showed that it was a 2020 Honda Accord and did not include the fact that it is a hybrid if that makes a difference. My car is a 2020 Honda Accord hybrid. Last incident was this past Saturday. August 9, 2025. This was the worst incident due to it took longer to correct itself and took three tries.

Failed head gasket. Resulting in complete engine replacement including turbo. Causing my car to go sluggish while driving dealership inspected and confirmed engine and turbo replacement needed all the lights on the dashboard came on at time of incident.

Car revs up at a stop sign, red light, heavy traffic, recently when making right turn. While in heavy traffic, stop and go barely moving, car stopped with foot on brake, traffic not moving, car revved up extremely high, the harder I stepped on the brake the higher it revved up, as cars started to move I took my foot off the brake, car jerked forward fast and I hit another car. No injuries, no major damage. Have taken car twice to mechanic, can’t find anything. Called Honda dealer same day of incident and brought in the car the following morning for diagnostic test, received phone call some hours later and told they can’t find anything wrong. There have been no warning lamps, and it happens unexpectedly. It’s happened before but very low and you can drive for months with nothing happening. I’ve been driving all year but this last time was different and happened 7/8 times. Found out on the internet there have been 10 recalls in 2019 one was for accelerator pedal may bind/fmvss 124, but I’ve never received notification on any of the 10 recalls.
