2022 Honda Accord: misfire or rough idle

Filed Jul 6, 2026 · Engine · MS

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 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 the federal safety agency 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.

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.

Filed Dec 10, 2025 · Electrical, Engine · GA

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.

Woke up and started my car, all the lights were on including engine light. no adapter cruise, steering light was on. Screen also was saying avoid speeding. Every notification was telling me go to the dealer ship. I took it Howdy Honda in Texas and they said we will need to do a diagnostic and it was for 255 for to see what the problem was. They looked and said I had code for po172(rich) and misfire on p0301 told me I need to replace fuel injectors. Which cost 1933$. Which is way too much and fuel injectors a labor should be covered under Federal Emissions Warranty but they said no. So I am filing a recall for fuel injectors for my 2022 Honda accord sports se. I am unable to drive because it’s in limp mode. I also have documentation from howdy for quote.

Potential for engine misfire

This occurred twice both happened on the highway going 65 mph. I accelerated as usual, suddenly the check engine light began blinking and I lost the ability to accelerate (limp mode). The car instantly dropped to 20 mph. After a minute, the check engine blinking light went away. Both times I was luckily able to get off of the highway going 20 mph. The first occurrence, I turned the car off for 30 minutes. After turning back on, car was fine as if nothing happened. The second occurrence, after calling Honda they recommended towing to dealership, which I did. At my dealership, they drove a lot, but could not duplicate issue. However, there was code DTC P0304 misfire. From the dealer paperwork "cylinder 4 swap spark plugs to known working plug misfire gone recommend replacing all plug random misfire. Removed and replaced all spark plugs." Since this repair two weeks ago, I have not had any issues and the acceleration feels less sluggish than before. This is a VERY serious issue that could result in injury or death if it occurs to others!
