The exhaust bolts are breaking causing the exhaust to leak. The related problems will likely be poor fuel economy, increased emissions and potentially failed emissions test. The catalytic convertor was already replaced on the same side as the exhaust manifold with the broken bolts. Problem was not noticed until the second bolt broke thus not sure when the original problem occurred. The problem appears to effecting numerous other vehicles thus a potential large global impact.

I have been hearing a rattling sound underneath my car while driving. Also when I turn off the car, especially when the car has been driven for a while, I hear a popping noise, maybe from the muffler area. I was told today that the catalytic converter needs to be replaced. I bought the car new, so I don't understand how that could be already with only 85k on the car.

I feel that I stopped the vehicle just seconds before it would have burst into flames, because when I opened the hood to see where the smoke and smell of burning metal and plastic was coming from the catalytic converter was completly red and glowing from the engine malfunction.
