I have a 2014 GLK350. Under acceleration, the interior of the car is so loud. Bought this car new, my wife drove this car for a few years and then we gave it to my daughters who drive it now. So, I dont remember the interior of the car being this loud when accelerating. If I had to compare to something, it sounds as if the catalytic converter is removed, but its not. I remember back in the day, guys would remove them from their trucks so that they sound louder, well...this is what it sort of sounds like. Its not loud when idling and its not loud when braking or cruising, its only under acceleration. Its pretty consistent. It seems louder when the engine is cold and not as loud but still very noticeable when the engine is warm.
