    sounds like catalytic converter or heat shield , this noise will trigger the knock sensor which in return will ****** the timing as a self preservation act , thus less power . if taking the car to the kia dealership is not an option , then seek professional help at least at some shop .

The "rattle" will be detonation caused by spontaneous combustion from incorrect air/fuel ratio and incorrect ignition timing
it is most prominent under acceleration or under load ( up hills , high speeds etc) and will melt pistons if left unattended
run the fault codes to find the faulty sensors , but I suspect that the heated oxygen sensors(HO2S) in the exhaust manifolds before the cat converters will be at fault as they report the gas composition back to the ECM so that the mixture can be adjusted correctly ( indicated by the poor economy)
there are knock sensors on the block which are indicated as faulty as they should be reporting this condition to the ECM to adjust the settings
finally it could come down to low fuel pressure or faulty injectors
what ever it is you need to get a proper fault code reading and have the problem fixed asap as it will cause engine damage if not fixed

It could very well be! Now that you mention it, the exhaust does sound louder when the engine is cold. Could that be a leak or something? But, it does get quieter after it warms up. Thanks for the response!

Heat shield rattling noise engine


Go to a a large hardware store and buy 2 band clamps that will fit around the heat shields and clamp them tight. This is the manufacturers approved fix for heat shield rattle. The fix sure beats the $1000.00 for a new catalytic converter assembly. I have done this fix dozens of times over the years of my car repair career.

Saturn Ion running loud and rough


Check for other loose heat shields.
The shield you removed would allow more noise to enter the cabin too.

Rattling noise sportage 2008


Sorry for the late reply but, no, it is not related to a loose heat shield. It is a louder rattling sound more like a loose bearing vibrating inside either the transmission or the clutch assembly. Only between 1600 and 1900 rpm. and it is not present under ou over these rpm. The rattle desappear when I lock the 4X4. Dealer is out of solution!!
