When i first start the vehicle it makes a loud whine noise for about 2 to 5 min. then seems to go away. if the vehicle sits for 3 to 4 hours it will do the same noise again. dealer told me that all the six cylinders make that noise and it's normal. have never owned a vehicle that makes a whine noise where something wasn't wrong especially at around 6000 miles on the vehicle. the vehicle was stationary when it happens but if you drive off right away the noise continues as you're driving. *tr
