Buzzing sound coming from under hood after turning off car? Please help me out.

[BB33]

Hello all,

I am new to the site, and have a question. I recently purchased a 2014 Mazda CX5 and I noticed something today I wanted to run by you all to see if it is normal. I was driving today like normal and came home and parked my car in my garage, my garage was shut and after I turned the engine off by pressing engine start stop button I got out of the car and I heard this buzzing sound that lasted maybe 30 seconds and then sounded like something shut off, sounded like sommething under the hood. Is that normal? I have never heard it before because usually my garage is open when I get out of the vehicle or I am outside and you can hear all the background noise such as other cars so I could not hear it before. Is that normal operation for the vehicle? Maybe it supposed to make that sound when you shut it off I just didnt notice it. If someone could please help me out here that would be great. Thank you. sounds like a buzzing sound under the engine area but it shut off after about 30 seconds. I was in the garage with the door closed so maybe it echos differently because usually I am outside. Thanks.

Normal as far as I can tell, I heard it very early on but never thought to ask anyone since the car always started and ran ;-)

it's normal. It's the electrical system/fan powering down. Now, if it doesn't shut off after 30 seconds, then you got a problem (detect)

Thanks, I wanna say it lasted maybe 30 seconds or so and then it sounded like something switched off. So this is definatley ok guys?

Yep....same with mine also. I remember the first few times I sat in my garage waiting to make sure it would shut off...now I don't even notice it anymore (drunk)
