I have a brand new 2011 Elantra GLS. I just want to know if it is normal for this 1.8 CCVT engine to sound like a diesel engine, even though it is a petrol engine. Diesel Engines normally create rattling sounds, which i can also hear from my 1.8 2011 Elantra Engine. I want to know some personal views and experiences about your Elantra 2011 GLS. Also, maybe some issues if there is any. Thanks!
