What 214 owners told NHTSA about the 2022 Honda Accord Plug In Hybrid

The car suddenly started to miss fire and lose power. This puts the driver and others in dangerous situations. If it happens when pulling out into traffic and the car misfired it could cause a serious crash. Honda service diagnosed that a blown head gasket causes coolant to leak into the cylinders, leading to engine misfires and a sudden loss of motive power at highway speeds. This issue is well documented on 2016 to 2022 honda Accords. There are many documented cases of this exact premature failure. Honda is aware of this issue and has awarded some owners goodwill repair when outside of warranty. There is currently ongoing litigation because of the 10s of thousands of head gasket failures. My car has 75k miles and went out of warranty at 60k miles. My goodwill request was denied by local regional Honda Rep but I elevated the request to corporate Honda and currently waiting on their response.

I am writing to file a complaint regarding a serious issue with my Honda vehicle involving the turbocharger system. The turbocharger appears to be failing, causing a significant reduction in vehicle speed and performance while driving. During operation, the vehicle suddenly loses power and acceleration, making it difficult and potentially unsafe to maintain normal traffic speeds. At the same time, multiple warning lights illuminate on the dashboard, indicating possible engine and system malfunctions. This issue creates a serious safety concern for both myself and other drivers, as the vehicle may unexpectedly slow down while traveling on highways or busy roadways. The condition has negatively impacted the reliability and dependability of my vehicle. I am requesting that Honda investigate this matter promptly and provide assistance in diagnosing and correcting the issue. If this problem is related to a known defect, recall, service bulletin, or warranty extension, I would appreciate being informed immediately.

I am submitting this complaint regarding an apparent head gasket failure involving my 2022 Honda Accord Sport 1.5T equipped with Honda's 1.5-liter turbocharged engine. At approximately 143,000 miles, I began experiencing coolant loss without any visible external leak. I also noticed rough operation and shaking during startup. Concerned about the symptoms, I consulted a Honda specialist who advised that the vehicle is exhibiting signs consistent with a failing head gasket and will likely require head gasket replacement. This vehicle has been meticulously maintained and serviced throughout ownership. I retain maintenance records and have taken exceptional care of the vehicle. There has been no abuse, neglect, overheating event, or failure to maintain the vehicle. Through my research, I have found numerous reports from owners of Honda vehicles equipped with the 1.5-liter turbocharged engine describing similar symptoms, including coolant loss, startup misfires, rough cold starts, coolant intrusion into cylinders, and premature head gasket failures. The consistency of these reports suggests a possible design or manufacturing defect affecting the durability of the engine. A failing head gasket can lead to loss of engine power, engine damage, misfires, overheating, and potentially unsafe driving conditions. Given the volume of owner complaints involving Honda's 1.5-liter turbocharged engines, I request that NHTSA investigate whether a safety-related defect exists and whether corrective action, including a recall or service campaign, is warranted.

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.

Our car, only 3 years old (2022) had a check engine light come on about a week ago. We went and had the code read, said cylinder 3 was misfiring. We replaced all the spark plugs and coils. All the lights went off and the car drove fine for another week. Then all of a sudden after driving 60+ miles, we were accelerating up a hill in very heavy traffic, and the car wouldn't accelerate. It wouldn't go more than 20-25 in a 45 as we were pulling out and we were almost hit because we couldn't go. The engine got a tad above the middle of the oil heat gauge. We had it towed. The dealership stated that it had a head gasket issue, with other issues, and that the engine block might be cracked. Currently are trying to charge us almost 7k to fix it.

car flashed engine temperature near limit, avoid heavy acceleration and high speed, see dealership warning on dash. sounds like water moving thru the dash board when driving or turning or right when starting car. took car in to dealership right away and they confirmed it is a head gasket issue and that they have at least 20 other cars there due to the same issue. my car has now been in the dealership for over a month and a half now and there is not a clear when it will be repaired due to how many other cars they have there with the same issue. i currently have a rental due to having the extended warranty. i want them to buy the car back so i can get another one with out issues. i have two teenagers that are also learning how to drive. all of the maintaince has been done at the honda dealership

My Honda is stalling and it started hesitating on 2/18/26 on the way to work. When getting in my car it started stalling and hesitating again, when getting on the road and driving all the lights came on and acted like it didn’t have fuel to go when the car has fuel.

Cracked cylinder head coolant leak from bad head gasket known issues through multiple owners

NHTSA ODI 11714797

The engine cylinder head developed a crack causing coolant leak, causing the coolant system to lose fluid. The leak originated from a hairline crack in the cylinder head, which has been confirmed by an independent, certified mechanic. The vehicle remained drivable initially, but a loss of coolant could lead to engine overheating, and catch on fire or smoke creating a potential safety hazard for the driver and others on the road. The vehicle was inspected at an authorized dealership at the direction of the manufacturer, which performed a teardown to diagnose the issue. After this inspection, additional engine components (timing chain and head gasket) were identified as damaged, though these failures were not present prior to the teardown. Other users facing similar leak issues were treated the same by dealership blaming other component issue and disregarding the visible crack. This defect appears to affect multiple vehicles of the same engine, as reported by other owners nationwide. Warning signs included coolant loss, which could escalate into a larger safety risk if not addressed. I have attached few user complains but if needed I can provide lot more user complaints around the nation as it is never ending.

Loss of power engine malfunction on 2022 Honda Accord sport 1.5 T experiencing repeated misfire codes, fuel injector failure, and suspected head gasket coolant intrusion. Vehicle has never overheated and maintenance has been performed as required. A second Honda service center advised, they have repaired multiple Accord Sport 1.5 vehicles with the same failure pattern. Honda Corporate opened case #16059306 but multiple voicemails to assigned case contact have gone unanswered. Concerned about safety due to potential engine failure or loss of power while driving.

I noticed random misfires months ago. I've replace my spark plug three times in 6 months. My coils are good, etc. It started getting worse about a month ago. It goes into limp mode and suddenly slows to 20 mph. Some days it won't start. The dash lights flash and the cars computer goes crazy it won't go over 20 mph. This is a widespread issue causing ppl to spend thousands and no fix in sight. Usually it hits between 15-90k miles. Twice I was on the interstate and it just slowed to 20 mph. I have had it at the dealer twice. They are clueless and can't do much without Honda stepping up. Honda needs to address this. My car was built in 2021 and somehow missed a major recall. It's putting stress on my catalytic converter and other parts that cost thousands to fix. I'm taking it in on Monday for the third time. If they can pinpoint it this time I'm afraid it might cost me thousands. It's a Honda and it shouldn't be having issues from 15k to 90k.

Misfire in cylinder 1 causing reduction of power while driving.

NHTSA ODI 11708216

Car started overheating randomly while driving and pulled over to see why. Opened the hood to white smoke everywhere and an active leak of coolant by the exhaust manifold. Took it to a mechanic and was told the cylinder head itself has porosity and/or a hairline crack. Pressure tested as well and can visibly see the leak coming from the cylinder head itself.

The fuel system on my 2022 Honda Accord malfunctioned and caused a sudden loss of power while my teenage son was driving. On 12/03/2025 at approximately 4:50 PM, the vehicle went into reduced-power (limp) mode while traveling in heavy highway traffic on a busy highway in a metro-area of >450,000 people. There was no shoulder available in which he could navigate onto. He was unable to accelerate and had to coast approximately one mile at low speed while many, many cars were driving around him during rush hour traffic , which created a dangerous situation with vehicles traveling at normal highway speeds. A Honda dealership has previously inspected and confirmed the problem. On 07/28/2025, the service center documented lean fuel condition, misfire codes (P0301, P0304), failed fuel-rail pressure, and injector-related faults. They recommended replacement of fuel-system components. The printed report and repair estimate are available for inspection upon request. Prior to the safety incident, the vehicle intermittently displayed symptoms such as hesitation during acceleration and irregular engine operation, but no permanent warning light stayed on. The failure has progressed over time and the same loss-of-power condition can recur at any time. This poses a risk because loss of propulsion in moving traffic can lead to a collision. The component issue has been confirmed by the Honda dealer, and documentation is attached. I am filing this report because the failure creates a safety hazard, has been reproduced by a local dealership, and has not been resolved. The repair show suggested I return to Honda for repair. Furthermore, during my research of this problem, I discovered tens of thousands of complaints from others experiencing this exact issue, including new low mileage vehicles. These complaints are available on all social media platforms and search engines, with each complaint indicating problems with the fuel injectors on engines using direct fuel injection.

This is very serious while driving on the highway vehicle warning for engine temperature right after check engine came on. I almos crashed becuase the engine temperature close to limit asked to reduce the acceleration but how can I slow down in 2 lines fast highway on very dark night. This very, very unsafely and Honda should take this seriously if they claim safety is priority.

Blown head gasket

Ive previously reported on here Errors I was getting, when pushing the gas, MULTIPLE all engine lights going off at once. Its like when you push the gas, the engine stallls, and then all the lights light up; The turbo charger errors; Fuel Sys 1 error; Fuel Sys 2 error; etc. The Cruise Control on does the same thing - especially if there is any type of incline. I know that MANY other Honda owners are experiencing the same and saw their complaints; I see there is now a recall, but WHY is my car NOT showing on here, when clearly it should be. Im asking for a file number and an investigation. Where can I go to get this looked at? Nobody is following up with me. I believe this is fitting Recall21V-215 or 20V-314
