Gear Whine Volume

So while playing with the Toyota baja truck i noticed that the gear whine noise volume slowly gets louder and louder untill its unbearable the longer you drive it, it actually happens with several cars.

is this a known issue? i cant seem to find anything about it while googling.

no one else who noticed that? it makes some cars unplayable after 10 minutes since they just turn into high pitched whining noise
