I'm not exactly sure why my car does this, but it automatically turns on the over drive/ sports feature without me having to press the sports button. This more so occurs when my gas is low and it will continuously turn on and then off again. I initially suspected that there was some sort of modulator problem, but I don't know enough about Honda Vehicles to say. I'm also having a problem with the gas gauge not registering the correct amount of gas in the tank, but it only fluctuates a little bit.
