[Childs Play]

I now seem to be having this issue as well. First noticed it about two months ago. Brought it to the dealership and they said I had a strut not seated properly. I mentioned the TSB for the sway bar but they didn't tighten them then. Went on my way and the noise was gone for about a week. Came back even worse after that.

Brought it into the same dealership and mentioned the TSB again. They didn't even acknowledge it. Said they didn't hear anything and gave me the car back.

Went to a different dealership yesterday first thing in the morning. They heard the noise and tightened the sway bars per the TSB. Was good after that until I hit a rough patch of road when going out for dinner later last night... I heard a slight tap sound when pulling back into the driveway that night.

Now the noise is back when pulling out of the driveway and over speed bumps this morning.

I also notice the sound slightly when starting from a stop at a red light.

I'm at a loss... Going to take it to one of the shops around here that are hopefully more competent than GM and have them check all/most of the suspension.

It's maddening...

Edit: I'm going to buy the nordlock washers and loctite. It looks like I could perform this myself. Maybe learn something during the process and not have to rely on GM to fix simple things that shouldn't be an issue in the first place.
