I usually just read these posts, but now I am in need of some advice.

Here is my background. I have an 08 Tahoe LT3 with 6000 miles. I bought it in September New, and around 4000 miles it started to have an intermittent high pitch squeal ( 750rpms to around 1500rpms). My first thoughts was a bad belt. I took it in and they said they couldn't duplicate.
So the second time in they heard it and threw a new belt on it. That did not fix it.
The third time they said it might be coming from the alternator. Sure why not, lets start throwing parts at it. They had to order it and so on the fourth attempt they pulled a TSB out of left field instead of putting the alternator on.
They gave me TSB #06-02-32-010A : Power Steering High Pitched Whistle Noise Heard in Any Gear with Vehicle Warm (No Fix Available at This Time)-(May 22, 2007) (models 2007 Escalade, Avalanche, Suburban, Silverado, Tahoe, Sierra, Yukon)

When I got this I was like WTF, this is from 07 and is coming up on 2yrs old. So I immediately call the GM help line and was given a case #. He told me he could not find this TSB. He then called back and said GM is working on this problem and will call me when they have a fix. I reminded him that this was an ongoing TSB for almost 2yrs and by the way the TSB I was given only applied to 2007 models, and mine was built in April of 08, he told me it applied to my truck also.

This high pitch squeal drives me insane and I asked for other options beside wait for a fix, I was not given any nor would I be given any compensation from GM.

I need help with this one. I really don't feel like trading it in after only having it a couple of months. I will keep taking it into the dealership to see if they can fix it I guess. But not what I really expect from a 50k truck. Sorry for the long post, and thanks for the help.

high pitched whistle noise

Shortdustoff,

I know what you are experiencing. Mine is an 07 Yukon and I started noticing it just a few months after I bought the vehicle in May 2007. I have already had it in the shop for the same thing as yours and the technicial changed every pully, thinking that would be the cure...it wasn't. The dealership did some checking and came back with the same TSB story and said GM is "working on it". If this has been a problem since the 2007 model year I would think a fix would have been developed by now. Mine is going back in to the shop on Tuesday for the same issue and I plan on letting them know I keep good records and won't hesitate initiating action to protect myself. The lemon law works in West Virginia as I had to use it for a 1999 Jeep Grand Cherokee. It took a while but we won. I don't know what position GM will take now that they are on the ropes financially, but we do have some protection under the law if that makes any difference now. Good luck with your Yukon and I'm sure you are like most of us - you would rather get it fixed than make an issue!

Glad to see someone else has experienced this problem, well not really glad. I am going to try to drop it off next week and tell them they can have it for a couple weeks and there will be a nice monetary reward if they can fix it. I just want it fixed, love the truck, hate the squeal. Good luck with yours KC.
