2020 Honda Accord Complaints

ENGINE — Filed 06/04/2026

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.

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.
