Has anyone had this issue? I'm noticing what may be excessive engine vibration on my 2012 Cruze Eco MT. My wife can feel the engine's vibration in the floorboards of the car when I accelerate past about 1600RPM. It sounds like I have an mild aftermarket exhaust or an exhaust resonator removed, but the whole system is completely stock. I even put the intake duct back in (which I removed to bypass the intake resonator), to make 100% sure that wasn't it, and that's not it.
I've also heard this before when an engine mount went bad. The vibration causes an exhaust-like noise. There's also noticeable vibration in the steering wheel when accelerating, especially below 1500RPM. I don't recall it being quite as bad before.
I checked the engine mounts over and couldn't see anything wrong from the surface. With previous cars, I could tell when they went bad because they were hydraulic and the fluid/grease just explodes and leaves a huge mess, but these seem to be solid rubber.
Any ideas what it could be? I'll have the dealer look into it when I drop it off hopefully this week to have the front strut assemblies replaced.
