Just my 2 cents, but I feel like in general that the VX has a certain roughness to it. I remember when I first got mine (25,000 miles) that I for the longest time was thinking there was a bearing or a gears, etc that may be worn because of a whine or rub sound i was hearing when letting off or under certain rolling conditions.

With it not getting any worse and having grown used to it, it now seems normal, but when I drive my wife's pilot or another, more "civilized" vehicle it becomes evident when I go back to the VX that it's a bit more beastly than other cars.

It's also a bit rougher and louder in the higher RPMs than other SUVs, etc.

So, I don't want to lull you into buying something that may have issues, but the fact you have heard the same thing in three different VXs has me thinking you are experiencing the same thing I did.

Even my best friends JGC seems quiet in comparison.

Throw some dynamat in it and call it a ride!!!

Good luck.
