Buzzing noise

[whitecoyote]

Question: What is the buzzing noise I hear when I unlock, or open the door on the 2010 SHO? The noise last a second or two.
It sounds like a pump.
Regards,

Just an educted guess, since I don't have a 2010 SHO...but, I get a similar noise with all my vehicles with HIDs. I believe it is the ballasts firing up. When you hit unlock, do the headlights come on? If they do, try hitting unlock and stand right next to the headlights and listen.

I've heard it too... I think its locks
Hey whitecoyote,
You in Macomb County did I see ?

Like the tint on red

Same noise occurs if you open the trunk lid too via the push button near the license plate if the key fob is on you. Doesn't have anything to do with the lights though. Reminds me of a relay of sorts allowing the entrance to your car/trunk with out using the unlock/lock feature on the fob. Here's a cool feature I noticed too. Did you guys notice how you can remotely roll down the windows and crack the sunroof while holding the unlock button down? Too bad you can't roll them back up though.

It's not lights as it happens during the day, it sounds like suspension adjustments, but we don't have that on the new SHO right? It sounds like a pump of some sort.

Yeah, I like that feature for the upcoming summers! It was in the manual.

Learn something new everyday! I didn't know about the trunk button near the license plate either.

Yes. :wave:

Guy at work has a G37 who inadvertently had the keys in his pocket and mashed the button down in the middle of a Houston Frog Strangler storm, opening the sunroof and all the windows. They totaled it.

That would suck!!! On this thing though you have to hold the button down for a while to activate it.

Same on the G37.

He sat down and the unlock button apparently was mashed for at least long enough to roll them all down.

3 months later his wife did the same thing to their RX400. Both of them drive Enclaves now because they dont do that.

It takes two presses, not an extended press, so maybe that'll help us.

VW has been doing this for years.

I know when you unlock a door (for vehicles with fobs) there is a buzzing, and its the seat moving backwards to allow you more room to get in. I know that sometimes in other vehicles you hear the fuel pump or something kick in when you open the car door (i really notice this on the flex)

The noise you are hearing is the in-tank fuel pump. It runs for a second or two when the door is opened or the unlock button is pushed so that the fuel system is primed and ready to go when you push the start button.

This makes the start time shorter and more repeatable.

If you ever do any work where you disconnect a fuel line, make sure you disconnect the battery to avoid accidently dumping a bunch of fuel when you open the door.

thats what I thought it sounded like.

I was looking for that trunk lid button and couldn't find it. The license plate is down pretty low.

Regarding the buzzing noise, I thought it was somewhat familiar, ie. the fuel pump. It sounds like it's coming from the interior though. Usually, you can only hear the fuel pump if you're standing behind the car.

Run your hand/fingers right above the license plate area. Where the bumper insert is for the plate. The switch is like the ones on the Explorers to open the rear glass.


I was wondering the same thing too. It must have some big ass fuel pump to make that kinda noise from inside the tank. Wonder if there is an external one outside the fuel tank also??

Thanks ****, I found it!

I don't know if I dreamt it, but I think I remember hearing something about some cars having two fuel pumps. It might make sense if that's the case with a turbo charged powerplant.

I believe you are correct.
I was just thinking, I have a 2009 Kawasaki Concours 14 motorcycle. It makes a similar noise when starting. I was told it's a pump that takes the gas fumes to the engine for better starting, so the gas fumes don't escape into the air.
