Noises after Ignition Shutoff
I bought a brand new 2012 slk. When I turn off the engine, there is a lot of noise and rattling underneath the car. The dealership mechanics say that is the catalytic converter cooling down and that it is normal. Is that right? Should I be worried. The car drives fine.
