A rattling noise erupted from underneath my 2009 crv, it was discovered that the heat shields mounts on the catalytic converters were rusted through at the mounts and were about to fall off the vehicle. The vehicle in only 3 years old, I am the second owner, purchased vehicle in Feb 2010. After further inspection it was discovered that the catalytic converter heat shields were being held on by radiator hose clamps. This means that in just one year the mounts to the heat shied were already rusted through. I purchased this from a Honda dealership. After calling the local Honda dealership I was told this was normal and not covered through the rust warranty. Heat shields are there for a reason and in order to prevent fires.
