If it is motor mounts you can check by opening the hood, putting it in drive. If the mounts are blown, you’ll see the engine lift up slightly under the torque. If it doesn’t move, you could left foot brake and increase revs a bit. If mounts are blow the engine will shift up around an inch on one side. Usually that’s associated with a clunk sound going over speed bumps as the engine jumps.
All that only happens if the mounts are completely failed. I guess partly failed could result in vibration but they aren’t that noticeable until they fail all together. They fail safe, there is still a metal to metal connection between engine and chassis if they’re blow, the rubber cushion just falls apart.
Had this in my mdx. Was a very noticeable clunk (like a blown LCA bush) every time I hit the gas and every speed bump.
