Is the sound easily reproducible? That is does the dealer acknowledge it also? Could it be a strut or a bushing or sway bar or...

My wife just called me to inform me of this exact same problem. She says it sounds like the vehicle is rubbing the pavement (bottoming out). Our's is a FWD 2009 2LT. Havn't gone to dealer on this yet.

Be certain the body is not rubbing on the turn. Mine makes the noise, at times, it is the air dam ( spoiler) plowing the pavement, if surfaces are uneven.

if it is the air dam--- dont remove it.... unless you want to lose up to 1/2 MPG.

GM Aero Engineer stated that adding the air dam alone increased mileage by up to 1/2 MPG

I've had issues with road debris (sand snow ) getting between the body and plastic fender skirt. It was causing a crunching noise.Was able to gently open the fender skirting and flush it with clean water.That seems to have helped. Don't know if this is the same problem that you guys are having.

Oh, mine is th air dam, for certain, but I have no intention of removing it.

I just experienced a similar issue. When turning left, under power (foot on the gas).. a whirring noise occurred until I straightened the wheels. I changed my oil and found the noise went away. I also discovered that my oil appeared to be low. Although I did not have a check engine light. The car takes 5.5 gallons, but the drained oil was less that 2.5. I think that while turning left, the car may have been starving for oil in the pickup, but not 100% sure. Check your oil.

Quarts not gallons. As for the check engine light, there is no oil level sensor.

Oops.. yea. What he said. :thumb: It's unbelievable to me that there is a sensor for every other dang thing, i.e. washerfluid, but hey.. Oil? How important could that crap be?

Wow! you're rubbing the air **** that often? I don't think I've ever hit the air **** on the traverse. I don't even hit it that often on my Silverado, and it's maybe 5" off the ground. You guys must have some rough roads there, or some terrible transitions from road to parking lot. Our Traverse has about 8-10 inches of clearance I think.

Did you find out what the problem was? When I was test driving used Traverses last year I drove one that had clicking noises when turning left. It was pretty clear to me that it was a problem with the CV joint after having CV joint problems with a few previous vehicles. If the sound is a series of rapid clicks, chances are that's your problem, and you can often see a tear in the CV boot that allowed dirt in.

Just wanted to state that this is exactly what happened to me. Experienced only on left turns while giving gas, and a whirring sound would occur until the turn was complete - almost sounded like an engine over-revving (but you could clearly hear that the engine was definitely NOT over-revving). I thought for sure I had some kind of power steering issue from all of the research I was doing. Once the oil was changed / topped off, the whirring noise completely went away. This is the only post I could find anywhere referring to an oil change solving the issue, and not an actual power steering issue.

I had the whining when turning, and sometimes turning would also cause a chatter. I changed my power steering fluid with Red Line power steering fluid. Both problems gone. I also changed the fluids in the trans, transfer case, and rear axle.

I had this problem on a used 2009 traverse that we bought a few months ago. Turns out I have a bent strut plate. They say it wont hurt anything, just makes a low noise. I don't even notice it now.

I also had this exact same thing happen to my 2011 Traverse LT 2WD. Accelerating from a stop, reverse or even turning right seemed to have no effect but when I turned left, I experienced an engine revving sound and whirling sound as you described. the vehicle would barely accelerate until I straightened the wheel, then it would catch up. I called multiple different mechanics including transmission specialists and all were dumfounded. I emptied the transmission fluid and replaced it with new and it had zero effect. It wasn't until I had the oil changed that it completely solved the problem. I called these same mechanics back and all indicated that changing the oil should have no effect on that particular issue and they had nothing to do with each other. That seems to make sense so I'm just checking if anyone had gotten any further with this issue as to what the cause might be.

low oil level?
dirty oil clogging the Cam phaser sensors?
