Car Engine Sound Cuts Out?

I was playing around with editing the advanced vehicle package, I noticed that the engine sound effect will cut out either at a certain speed or when the car is far enough from the camera. I removed the attenuation on it, I am not sure why it still occurs. The car specs were modified.

You need to enter its engine sound cue, select the crossfade by param, enter the parameter 2 and add to the fade out rpm value end, maybe also add a little bit to the fade out start.
