Class Action Lawsuit Over Honda 1.5L Turbo Oil Dilution Problems. MY2018-2021

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

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.

    I have a 2018 CR-V with the 1.5t and never had a check engine light but kept having software issues. I took it in as I guess there is a recall Honda never let me know for the fuel issues. Well they wanted to take the valve cover off because they stated sludge on the dipstick ( I checked the dipstick and it was just dirty with no sludge or metal bits) well after 10 days of holding my CR-V they sent me a video of shiny metal bits and no sludge underneath my valve cover. Stated a P0299 code and I need a new turbo and engine. My oil has always had a strong solvent odor after every change but Honda told me my CR-V is not part of the fuel oil issues even when other mechanics stressed it when working on my CR-V prior to this new problem. Has anyone else had the same oil or turbocharger issues? They stated oil or sludge got into the turbo and it exploded in the engine. Will never buy or tell anyone else to buy a Honda if they are that bad on a newer vehicle engine.
    Funny part I just hit over the 60,000 because of all the highway miles and drove perfectly prior to going to the dealership so I guess turbo exploded in the engine at the dealership so I have to tow it if I can not afford a new engine and turbo charger.

    I have. 2019 Honda Civic with the 1.5 litre turbo engine. I have experienced numerous symptoms of oil dilution. Honda Inc I made aware of the recall for 2016-2018 1.5 litre oil dilution issue. I’m being told costs are on me and currently Honda has not admitted fault. The dealer and Honda Canada conflict one another. I am from Canada and wish to receive guidance of being added to the 2019-2021 lawsuit.

    Same Issue with the oil dilution. Everytime I would check the oil it was over the full mark & you can smell the gas. Brought it to Honda and they said everything was normal but they will check it. When I left the car and came back hours later it was in the exact same spot. I know the car never moved bcuz after I left the car it started to rain hard. When I got back the car was bone dry underneath took a pic and showed the guy and he basically lied and said it was checked and nothing was wrong with the car. So I brought the rag I wiped the dipstick with and said “I guess its normal to smell gasoline after checking your oil”. He just shook his head and said nothing.

    I purchased a 2018 crv (1.5turbo) and during my transaction, nothing was ever mentioned about the oil dilution .
    I finally found out when my crv was acting powerless and missing erratically and notified independence Honda dealership and they still never mentioned the oil dilution.
