| Description of the problem | Whenever i accelerate on the highway my engine would rev to a high rpm with a delayed reaction in order to get the car accelerated. Also, whenever i slow down my car for a stop light or stop sign, my engine would rev to a high rpm to slow down my car. I asked the hyundai dealerships, they said the everything is okay, however i can tell right away there's a difference with my 2015 hyundai sonata vs my girlfriends 2015 hyundai sonata, exactly the same year and model and trim, but the drive is totally different. Also, i can also tell because the mpg on my car is far lower than my girlfriends. And she has a heavy foot on the gas petal. It doesn't make sense. The hyundai dealership also reset the computer of the car, but no difference. |
