2018 Honda Accord Owner Comments

problem #7

Sep 022019

Accord Touring 1.5L Turbo

  • CVT transmission
  • 8,000 miles


The check engine light came on and the car shut down while driving at 60 mph and we coasted safely into a parking lot. We took into David McDavid Honda in Frisco, TX where they ran diagnostics and drove the car 2 miles and stated their computer systems didn't find any error code and dismissed our issue.

We did some research and apparently there is an issue with gas in the oil. We decided to check the oil stick and the moment we pulled it out the smell of gasoline was strong. The oil resisted way above the max fill line (the dipstick was wiped and put back in for a minute and pulled out).

Accord Sport 1.5t

  • Automatic transmission
  • 250 miles

Since day on the dipstick always looked over full, but never thought to sniff for gas until today. I never could get an actual reading because the way it looked (above the line) so I'd just bring in and change it when oil said at 50%. On one occasion the car slammed its brakes while trying to avoid a construction plate covering a hole on street. Cars we're parked but I didn't get that close to the parked cars when trying to swerve plates. Car has a remote start but they don't me. I have to now buy a different key chain and have Honda program it to my car so I can use my remote start. So Honda Accord sport 1.5t is also effected with this oil/gas dilution issue.

Accord EX 1.5t

  • CVT transmission
  • 1,500 miles

Honda has a fuel dilution problem with the 1.5t engine. Oil level rises on the dipstick, due to fuel getting into the oil. Had an oil sample taken and the results after 5000 miles on mobil one, the oil showed oil dilution above 5 percent and a significant loss in oil viscosity. Honda has had a good reputation with engine longevity, but time will tell with this one.

Do not buy Honda. Motor oil smells like gas.

Accord Sport 1.5L Turbo

  • CVT transmission
  • 2,289 miles

I am really disappointed in this car. Everything else about the car is awesome. However, having gas in the oil is a major problem and it appears that Honda has known about this for a while now. I really hope that they get this taken care of and I have no other problems with the vehicle.

Accord EXL 2.0L

  • Automatic transmission
  • 18,000 miles

Had 3 different mechanics check my oil. All said gas was in it. I sold the car, it's someone else's problem now. I went to Toyota and won't look back.

Thanks a lot Honda

Accord Sport 1.5t

  • CVT transmission
  • 5,000 miles

Honda has a big problem with their 1.5L turbo engines. They are trying to keep it quiet but this engine accumulates excessive gasoline in the oil which causes increased wear and tear. Honda which was always the leader with great engines completely dropped the ball and are trying to cover it up and telling people nothing is wrong because they know your cars engine will not go the distance, but will get out of warranty before failure. They have already been forced in China to recall over 350,000 cars with this engine and they are also considering not allowing Honda to sell the 1.5L turbo in China. Also a class action lawsuit is being developed in the United States because of this engine.

The main problem is from excessive Blow-Back which is something that should only happen on worn down engines with many years of wear on their piston rings. This is very important because your oil begins to lose its viscosity when gasoline is introduced and your engine starts wearing down much quicker. This can also be a catalyst to engine knock which will destroy your engine. The interior cabin can also start smelling like gasoline.

This problem is exasperated if you drive in colder weather, drive short distances (under 5 miles), or accelerate quickly (engine lugging). Don't take my word for it, do some research because I think its terrible Honda is covering this up.
