Oil diluted with fuel (3/4" above the full mark on the dipstick) - this is a problem with honda's 1.5 turbo engine (civic, crv). Others with this issue have reported their vehicles stalling while driving at 70 MPH -- definitely a safety issue.

At 4400 miles on the 2018 civic hatchback 1.5 l (approx 4 mos) the vehicle lost power momentarily while accelerating at about 30 MPH and had a strong gas smell in the cabin. A check of the oil showed that it was extremely overfilled when previous checks did not. Honda dealer (ide honda, rochester, ny) replaced the oil and offered no corrective action or information.

Strong smell of fuel in the cabin due to known Honda oil dilution associated with the 1.5 turbo engine. Honda has a “fix” for issue but states only cold weather states are affected. Our 2018 Honda Civic has had this issue for over 2 years now.

This car's evaporator is defective. Evaporator failure left many individuals, including myself, without air conditioning. In California, where I live, the temperature can rise above 100 degrees.

There is fuel leaking into engine oil and thinning it out. My mechanic said there's a software issue causing it but a recall hasn't happened for it. It's hurting my car performance and making my car speed up faster even when breaking.

Water leakage from the engine bay that damages coil packs and spark plugs. Coil pack seal is not durable enough to repel water once its introduce from the hood scoop.

Driving on the highway and my check engine light starting to flash. I experienced loss of power and hesitation during acceleration. I got home and scanned my computer and it returned P0304.

The a/c evaporator has apparently stopped working. The condensor had to be replaced because it was not manufactured to specifications, and a recall was generated. I am of the opinion that the same thing has happened to the evaporator, as this is a part that should not have failed.

Honda did extent the warranty to 10 years from the original purchase date.

Suspected oil dilution... Recent dealership oil change, less than a week later, the volume of "oil" was approx. 1/2 inch over the top of the dip stick measurement section.
