I am unhappy with the engine idle sound of my 2011 Odyssey EX-L and wonder if it is normal. When the engine is fully heated up (after some driving), I start hearing small yet diesel-like engine sound (periodic sound commonly found in old engine) when I stopped (when RPM is round 0.6~0.7). Is there anyone hearing the same sound? The sound is pretty unpleasant and annoying, considering a brand new car with only 1000 miles. I have been extremely happy with the engine sound of my 5 years old 4-cylinder Accord. Quite disappointed about the engine sound in V6 2011 Odyssey. Is VCM making this sound? I am thinking about taking my car to the dealer to check other odysseys make same idle noise. Any comment would be appreciated.
