I've noticed a high speed (3-4 per second) ticking sound coming from the underside of the Compass after I've idled into the garageand shut the engine off. It's been under 30deg since we bought the Compass, so this may be just a cold weather sound.

It's not the normal asynchronous contraction noises of engine components I'm used to. It sounds like something in the CVT is still spining (regular, yet slowly decreasing rpm). I haven't sat & waited until it stops, but remains after a few minutes of emptying groceries.

Anyone else's Compass make this sound?

I've heard the same thing and I think it is the catalytic converter cooling off. But not 100% sure.

havent heard it on my compass, but the subaru i traded in on it used to tick after the car was turned off and in the garage, it was the catalytic converter

I had this noise on my previous 2 cars (Chevrolet Venture and Toyota Corolla), both were because of the catalytic converter cooling down and it is normal.

Thanks

Catalytic Converter? My last three vehicles didn't do that so I never would have thought of it. Well okay then. Thanks!
