The car had a strong smell of fuel in cabin when starting on various occasions. The car also temporarily stalled and lost power when coming to a corner turning and also three times when coming off the freeway. The car was always warmed up and in California during the warm weather. Dealer noted fuel smell in oil and increased oil level. Had oil changed and was told a fix was coming soon. Took car in to dealer months later for a recall, a BCM recall and again I told them that the oil smelled of fuel after 500 miles since oil change. Waiting for manager to call me back with update on fix. It is a 2018 Honda Accord 1.5 Liter Turbo. 26,000 miles on motor. I bought the car from the dealer in January 2020.

On 3 separate occasions, my Honda Accord 1.5T has lost power while driving in traffic. All of the warning lights came on, and I could not go over 10 mph. Fortunately, I was able to turn onto a side street each time. I turned off the engine and after a few minutes restarted…only once was I able to regain power and drive home with normal power. My car went to the dealership each time, and they have told me they cannot duplicate the issue. And now, the dealership has had my vehicle for almost 2 months. The service agent said he has never seen anything like it […] Honda dealership and Honda Corporate has no solutions, other than just live with it. A car slowing down in heavy traffic or on the expressway is a major accident waiting to happen, and Honda doesn’t seem to care.
