Whistling noise from '08 Cherokee Laredo while accelerating and turning off.
I've had my '08 Cherokee Laredo (3.7 v6 ) for about 2 months now. Balance of 36/3 warrenty just expired and I have noticed a whistling noise coming from the engine. The noise sounds like a wooden train whistle ('woooooot"). It happens
while accelerating halfway through 1st gear (AT) from a dead stop
once you've come to a stop, immediately as you enter idle it'll give a short "woot" sound
and finally when you turn the truck off it will usually give another short "woot" sound
This does not happen every day and happens in cold and warm weather. A service bulletin that has the same symptoms while the heating and ac is on has been issued for this vehicle but this happens even with those off. The dealership today told me they can't replicate the problem (of course) so I'm currently at a loss.
