Honda owners are raising a class action lawsuit against the automaker, alleging that Honda has been selling 2018-2021 models with an engine defect that causes excessive oil dilution. The plaintiffs claim that the defect reduces performance and drivability, and may even lead to engine failure. If you own a MY2018-2021 Honda with the “Earth Dreams” 1.5L turbo direct injection engine, you may want to consider joining the class action lawsuit.
Read on for more information about the Honda oil dilution lawsuit and what it could mean for affected owners.
Honda 1.5LT Oil Dilution Problems
Owners allege that model year 2019-2021 CR-V, Civic and 2018-2021 Accord vehicles are experiencing fuel contamination of the engine oil. Also known as crankcase dilution, it is a process where fuel is leaked into engine oil when it travels towards the crankcase. While this process occurs in every engine, excessive amounts of fuel leaking into the engine contributes significantly to engine wear. In the case of the Honda 1.5L turbo engine, oil dilution results in the oil level rising, failure of engine bearings and other internal engine components. This may result in catastrophic engine failure and even stalling while driving.
Owners have also alleged that when taking their vehicles to Honda for repair, they are told that the level of engine oil dilution is considered normal. As a result, they are denied warranty coverage and forced to pay out-of-pocket for repairs.
Despite Owner Complaints, Honda Failed to Repair Vehicles Adequately
The suit claims Honda has been long aware of the oil dilution problems. Yet despite knowledge of this defect, Honda has failed to adequately repair vehicles affected by the engine defect. Even with numerous consumer complaints it has received, and information received straight from dealerships, Honda continued to conceal the issue.
Additionally, owners whose vehicles are within the warranty period allege Honda has done nothing to address the engine defect. Honda America has instead blamed owners for not driving their vehicles for longer distances.
The following vehicles are affected by this class action lawsuit:
- 2018-2021 Honda Accord
- 2019-2021 Honda CR-V
- 2019-2021 Honda Civic

Honda Owner Voices
Strong odor of gasoline in the engine and rising oil level. Car doesn’t even have 200 miles on it! this is not what I had expected from a Honda.
I have the oil dilution problem with my 2018 cr-v. I bought the car in march of this year, brand new. I currently have 9000 miles and had to have the oil changed four times due to gas mixing with the oil, strong gas odor and oil over full. I have also had an issue with all the warning lights coming on at once and cycling over and over, this has happened at least three times. I contacted Honda America and was told this was a normal occurrence and no harm will come to my engine. I did not know this was an issue until the check engine light came on.
After driving a short distance on a city street, I noticed a gas smell in the cabin. upon additional research, I learned that other CR-V owners have experienced the same situation with oil dilution (gas getting mixed in with oil). When I checked the oil, the level was over what is should be and the dipstick smelled of gas.
