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 federal safety agency investigate whether this represents a recurring safety-related issue affecting Honda vehicles equipped with the 1.5L turbocharged engine.

I am the original owner of a 2020 Honda Accord 1.5 Turbo. The vehicle has developed a check engine light, rough engine operation with misfires, and reduced fuel economy at Mileage: 72,207. The vehicle was diagnosed at Honda of Reseda with failed fuel injectors. American Honda reviewed the matter under Case #16435337 and offered a one-time goodwill accommodation that would require an out-of-pocket payment of $1,058.58 plus applicable fees and taxes. I respectfully declined the offer because fuel injector failures causing these exact symptoms appear to be a known and recurring issue on many 2018–2022 Honda Accord 1.5 Turbo models, often occurring at relatively low mileage. Honda has issued technical communications regarding injector-related diagnostic trouble codes (such as P030x and P0172) on these vehicles. I am filing this complaint to document the defect and request a thorough investigation so that a proper recall or comprehensive remedy can be implemented for all affected owners.

I own a 2020 Honda Accord EX-L with a 1.5T turbo engine. The problem happened on January 20, 2026, when my car had 66,988 miles. While my husband was driving it, the engine warning light came on, and the car suddenly lost power in the middle of the road. Fortunately, there was no car behind me at the time. Otherwise, he could have been in a serious accident. He was able to pull into a nearby parking lot. To avoid further damage, we had the car towed to a certified Honda dealership for diagnosis. The dealer told me that the fuel injectors had failed and needed to be replaced. The total repair cost was $1,851. The dealer checked my vehicle identification number (VIN) and told me there was no recall for my car, even though some vehicles of the same model and year do have recalls for similar issues. Because of this, I had to pay the full repair cost out of pocket. I kept the repair receipt. I later contacted Honda’s customer service to report the issue. However, the representative informed me that Honda could not provide assistance because my VIN was not included in the recall list.

I was driving on the freeway and all of a sudden my vehicle didn’t want to accelerate. It began to jerk violently when I would press the gas to accelerate, but my car couldn’t go the speed limit & vehicles behind me almost collided with my car. I then took my car to service and told them what happened and they said my fuel injectors needed to be replaced. The service advisor at the Honda service department that the fuel injectors fail early on the type of Honda accord I have. That it is a known issue for those model for the injectors to fail. I even took it to an independent shop and he also confirmed the injectors are bad. The first time it happened was in December & I got a flashing check engine light, but after that the light didn’t appear. Until 12-31-2025 the check engine light fully came on. Prior to the failure there were no warning lights. If Honda knows there is a known problem on the fuel injectors why don’t they have a recall. It put mine & the lives of others in danger. Not to mention I was quoted over $2,000.00 from the Honda dealership for the repairs.
