2014 Honda Accord: misfire or rough idle

Filed Oct 3, 2025 · Engine · CA

I own a 2014 Honda Accord with the 2.4L engine, which has a well-documented oil consumption defect. Recently, I discovered that my engine was nearly dry and required approximately 60 ounces of oil just to bring the dipstick reading to the midpoint between the “low” and “full” marks. The car had been idling roughly at cold start, and the check engine light flickered briefly, which I now understand was due to oil starvation. This condition creates a serious safety hazard because sudden oil loss can lead to engine misfires, stalling, loss of power while driving, and potential damage to the catalytic converter. This is not an isolated incident — thousands of Accord owners from the same model years have reported excessive oil consumption, and Honda has issued technical service bulletins acknowledging the defect. Despite this, no recall has been issued and many affected owners are left to continually top off oil or risk engine damage. I believe this should be investigated as a widespread safety defect, as many drivers may not realize their cars are burning oil until the engine is dangerously low.

My 2014 honda accord is experiencing excessive oil consumption, lack of engine power, engine stalling issues and overall unsafe drivability conditions. I took the vehicle to albany honda on 5/4/2020 for them to diagnose and repair the issue but they could not duplicate the problems I was experiencing so they recommended an oil change and gasket valve cover replacement and charged me $262.08 for the service. I paid for the service and drove my vehicle off the lot with the severe issues still present. After 30 minutes of driving the vehicle the engine struggled to get up hills, began jerking, jolting violently and I was almost hit by oncoming traffic, I immediately called serve department back at honda and told them about the incident and that I was bringing the car back and for them to do a thorough inspection and diagnosis of the vehicle as it had become a safety hazard and I didn't feel safe driving it. The next day the tells me that they 'test drove' the vehicle again and that the mechanic noticed a 'slight surge' but still could not pinpoint the issue. They then recommended a host of completely unrelated expensive repairs that would cost me $600 to $700; money that absolutely no one has to spare during this nationwide pandemic. Frustrated and disappointed I ended up taking my vehicle to another certified repair shop and they diagnosed the issue as p0300'as an engine misfire. The shop refused to work on the vehicle because they said it's a serious issue and that honda should be responsible to repair my vehicle because they problem is a tsb bad piston rings that honda needs to address.

Engine cranks but fails to start, or starts sluggishly with rough idle after a few seconds of cranking in cold weather. I believe this to be a fuel pump pressure problem.
