Start up and Reverse Noise

[Begno]

Afternoon all,

Has anyone noticed a noise when walking up to the vehicle? Also, when putting into reverse, another noise like an adjustment or something. Not a loud clunk or anything. Just curious as to what those sounds could be.

take a video of the noise, upload it to youtube and then post the link in here
preferably a longer video than 5 seconds lol

for reference some of the sounds you may hear are the fuel pump pre-charging, and air pump engaging if you have air ride

Yep, it comes alive as it senses a fob near. All normal…..

I noticed that mine is full of those noises too when you approach it...it's it a bit strange all of that happens even if you're not in the car (if you just want to grab something out of the car you have to listen to that). It's not super annoying.

Does anyone know what all the clicks/clunks are if you sit inside the vehicle within 2-3 minutes of shutting it off? There's all kinds of noises that occur...guessing it's a bunch of relays or something, but never had that in a vehicle before either.

It's the lifters taking roll-call.

I get the same thing when I get near my Yukon. Like others have said, it sounds like pumps priming vehicle getting ready for action. Only lasts a few seconds. I'll try and record a video later today.

Yup same here. Feel like it's getting ready to transform into a giant robot on something...

If you have a diesel, it is the vehicle sensing the fob and igniting the glow plugs.
