    whining noise 2006 sts

    We came down from a mountain - about 40 miles downhill, hot outside and at the bottom my car started to make a whining noise. Could it be the air conditioner?

    can be anything from the tires to bearing hub to the AC, if it still exist while the AC off then it's not the AC.

    There are lots of different items that can whine. Mine ended up being a wheel hub/bearing. I have also seen the diff whine on some vehicles

    70k miles? Anything from water pump or alternator to transmission torque converter or any of the above. Get it to a shop with a lift and listen.

    Hello momellis,

    I am sorry to hear that you are experiencing a sound emanating from the bottom of your STS. I do see you are reaching out to the community to see if they have any idea what the sound could be. If you were interested in taking your vehicle to the dealership in regards to this sound, I would be more than happy to assist you in working with them. Please private message me or send me an email at socialmedia@gm.com if you would like any assistance. Thank you very much for your time.
