After 4-5 seconds starting up the the journey, a 2-3 second long "Hmmm" sound is created. After this, sound never comes throughout the journey. It could be only heard again if you switch off the engine and restart and start the journey. Problem appears only when going forward (not in the reverse gear). This is an auto transmission car. No other problems or difference is felt while on move.
