New guy with a question

[oldsspguy]

Hello all,
I just bought a used 2015 GT premium with 8000 miles and have a question about an odd noise.

After driving I shut off the car and about 30 seconds later inside the cabin there is an odd buzzing sound for about a second then it's gone but it always happens like clock work.
Any ideas?

Thank

Steering wheel locking maybe? Just a guess. I wouldn't worry about it

Thats my thought too. Op you got the enhanced security package?

Yes I do..why?

With that package when you turn off ignition the car performs an auto lock down of a few things. Could be some of the noises you hear.

Throttle body reset/check after shutdown. Happens just about in the time frame you mentioned.

If you are under the hood quick after shut down, it will scare the shit out of you. lol

Thanks all very much appreciated.

Enhanced security package locks the center console which is probably the noise you are hearing.

Not security feature, lethal is correct +1 TB actuation
