I have a 2018 EX-L with a little over 50K miles. Have noticed problem 6-10 times that it will make a sound immediately after shutting it off that sounds like something winding down. After reading some of the conversations on the forum I thought it might be the turbo but none of the comments fit what I'm hearing. I do also hear the turbo sound when slowing down but this is actually when the car is just shut off. Just trying to see if I need to be worried. Thanks!!
