2018 Honda Accord Hybrid Fuel system Problems

“2018 Honda Accord Hybrid touring purchased 9/25/20 with 44k miles. Within the 2 weeks I've owned this car I have already noticed two large issues. The first and most disheartening is the terribly reduced gas mileage compared to what it's rated for. I'm topping out in the low 30's when it's rated for 47mpg. The second issue is the loud humming noise while driving. A quick search online shows that many other owners also have both these issues.”

“After filling the fuel tank, a strong odor of gasoline was smelled in the car. The car was taken to the local Honda dealer and after 5 days they still haven't found the cause of the problem. They have attempted to deodorize the car each day and ventilate it using fans but I don't know if the fuel system has been checked.”

“First 7,000 miles got 47 mpg, Honda did back up camera software update, and mpg dropped to 42, then 38, and now 34, on all the same types of driving. Electric engine hardly runs and not nearly as much as earlier. Seems to be related to the temperature, the colder the temperature, the lower the mpg.”

“When going around a corner and the switch from electric to gas (hybrid vehicle) occurs the car seems to stall and consequently looses speed for a second or two. This happens when starting from a stop and at highway speeds.”

“Car has been throwing check engine light codes for different things for the past three years. First, the spark plugs needed to be replaced, then the electric coolant pump. After each repair, the check engine light came back on as soon as 4 days after but as late as a month after. Most recently, while driving on the highway the car check engine light came on and began flashing and the vehicle would not accelerate past 20mph. …”
