Incident

While driving, my vehicle experienced a sudden engine malfunction consistent with a failed head gasket. The engine began misfiring, shaking, and losing power, and the check engine light began flashing. The vehicle became unsafe to operate. The failed component is the engine head gasket, and the vehicle is available for inspection upon request. The sudden loss of engine performance created a serious safety concern. I was driving on a public roadway when the engine began misfiring and losing power, making it difficult to safely maintain speed and operate the vehicle. A sudden loss of power while driving increases the risk of being rear-ended or becoming involved in a collision, particularly in traffic, while merging, or at highway speeds. The vehicle was inspected and diagnosed by an authorized Honda dealership, which confirmed the head gasket failure. I also spoke with independent mechanics who were immediately familiar with this type of failure on Honda's 1.5L turbocharged engines. Although Honda diagnosed the problem, my request for goodwill assistance was denied because the vehicle was outside the warranty period. The vehicle has been inspected by Honda and is available for further inspection if requested. It has not been inspected by law enforcement or my insurance company because no accident occurred. As the condition progressed, the engine developed a rough idle and intermittent misfires. Eventually, the check engine light began flashing, and the engine began shaking and losing power while I was driving. These warning signs escalated into a condition that I believe presented a significant safety risk. I am submitting this complaint because an engine that suddenly loses power while being driven poses a serious safety hazard to both the driver and others on the road. I respectfully request that the NHTSA investigate whether this represents a recurring safety-related issue affecting Honda vehicles equipped with the 1.5L turbocharged engine.

Blown Head Gasket. This caused major cost in repairs and going without a vehicle, This was a known failure issue with Honda 2020 Accord Sport. I have requested a "goodwill claim" with my nearest Honda dealer and not have gotten a phone call nor email. I have all my repair documents and a well maintenance log on my vehicle. With this being a known issue, it should be covered in the lifetime warranty that I received from the dealership when purchased but it excluded seals and gaskets on my paperwork.

Incident

Jun 2, 2026

I turned my car on and about 10 warning lights came on the car- drove it straight to the dealer where they told me the head gasket was leaking into cylinder 3 gave me an estimate of over 5k. Every mechanic I have called has told me how unusual it is for a car not very old and not over heating to have a blown gasket head. I was looking online and have seen how common the blown gasket head was on Honda accord models 1.5 from 2018-2022. There is nothing in the car no over heating no damage though could have cause it to leak unless it wasn’t properly installed which seeing how common it is might be the case. And how unusual it is according to many mechanics. The car has 115000 miles but has never had an issue and I wasn’t driving or anything when the warning lights came on

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The suspected failed components involve the 1.5L engine system and head gasket on my 2020 Honda Accord. The vehicle experienced frequent overheating along with repeated check engine light activation. Multiple mechanics, including Heritage Honda Parkville, indicated that head gasket failure is a common issue with this engine type. The vehicle remains available for inspection upon request. 2. How was your safety or the safety of others put at risk? My safety was put at risk due to the vehicle frequently overheating while driving. An overheating engine can lead to sudden vehicle breakdown, engine failure, loss of power, or being stranded unexpectedly in traffic or unsafe locations. The recurring check engine light and unresolved engine concerns created uncertainty regarding the reliability and safe operation of the vehicle during daily commuting and long-distance travel. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The concern was initially discussed by technician [XXX] at Heritage Honda Parkville during my service visit on March 19, 2026. The technician advised that the “most common issue” with these engines along with my vehicle is head gasket failure. Additionally, multiple independent reputable mechanics later echoed the same concern, stating they have seen numerous Honda Accord vehicles with the 1.5L turbo engine require head gasket replacement and, in many cases, full engine replacement. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was inspected by Heritage Honda Parkville service personnel and has also been evaluated by multiple independent mechanics. The issue has additionally been reported to American Honda Corporate under Case Number XXX. The vehicle has not been inspected by police or insurance representatives.

Car just started jerking and eventually stopped. I had it checked and was told the turbo was gone. Took it to Honda they said the head gaskets are blown. The car is 5 1/2 years old and it not one time ever ran hot. I’m not the only one with this issue. Honda needs to do something to fix this. Every car that goes to service has this issue something is definitely not right

Honda accords have a 1.5 L engine, which all have an issue with the head gaskets either overheating or mixing coolant into the cylinders. They’re all doing it eventually because there is a design flaw Honda doesn’t want to honor it and the car will just stop on you on the freeway because coolant touches the spark plugs. Honda is denying the issue when there’s a whole Facebook page and Internet, page of people saying the same thing they’re quoting and unreasonable amount to fix it almost the cost of the car. It is a very dangerous safety issue and eventually someone could die and needs to make a recall immediately before that happens. Most shops don’t even want to touch the car because it’s a safety issue. If we can get this past ASAP for anybody who has that car or anybody that’s gonna buy that car the safety for them in their family.

I have constantly had to replace spark plugs within the last year — all lights are on dashboard. Finally took it and got a P0372 code, rough idling and misfiring, and stalling. Car once cut off on me while driving. Took it to the Honda dealership and it is indeed my fuel injectors and gasket. I have tried to get in touch about a possible recall but the Honda Manufacturer are failing to release a recall. With all lights on dashboard, NO features of the car can be used (cruise control, road departure, lane keep assist, collision mitigation, hill start assist, traction control, brake hold, and tpms) I’m looking forward to a recall coming as soon as possible. I have done my research and thousands of people are having the SAME issue, it is frustrating especially with the cost of work having to be done. Nobody should have to purchase a new car because of a defect of the manufacturer or too lazy to investigate the issue. HONDA Salesmen and mechanics all say the same thing about the 1.5L Sports model. Over 3,400 worth of work due to a problem I did not cause.
