OK, I have 20k miles on my 2010 and it has started making a new noise. When you are just cruising at around 40 mph and the motor switches over to gas, if you are just feathering the throttle you can hear a whistling sound. Took it into the dealer and surprise-the mechanic heard the same sound! They said they had never heard that before but it definitely was not normal so they would need to keep it a couple of days to diagnose the problem. Three days later they changed their mind and said that it is normal. They also said they test drove a new one on the lot and were able to duplicate the noise. Anyone else have this issue? Any information would be helpful. TIA, Mike
