[2015 Escalade] (purchased August 2014) I was wondering if you could listen to this audio and tell me if this engine moan is typical of this engine? When I purchased I never noticed it, it later developed. I'm parked and revving engine up and down from 2000 rpm, as rpms go down you hear the moan.

Where's the audio?

The new engine has direct injection. It's suppose to be loud.

 

[DreamCadi]

evois I made no mention about loudness, that isn't what I was bringing up in this thread it's more related to the MOAN noise, which isn't from injectors. I have had several prior GM vehicles with direct injection engines without this moan and that is why this concerns me.

Noisy transmission front pump.

Mine was a December build 2015i..... and i just went out and ran it as you did....makes the same noise. I believe what Tec80 said above is probably correct......and is normal. In fact....I can here the trans pump sort of sounding like a "turbine" as it winds up in the lower gears. This is a powerful engine, lots of torque and a complex new trans.....there WILL be sounds and this is not a bad one.

I used to hear my hybrid's whirring sound everytime the 4auto kicks in. The platinum sounds the same however with its mouth open like a burping loud?
