I have been noticing some a noise from the rear end of my 12' SHO and do not know if the the TSB on the earlier modules applies? :braincramp:

Welcome to the forum!

Did you check for Uncle Vinny stuffed in the trunk?

I'm not aware of a TSB for a rearend noise, but that might be because I haven't encountered the issue. Are you referring to the TSB for the sunshade?

I checked the trunk it really only happens on light acceleration and in low speed turns it kind of resembles whats on the following TSB

10-22-4

* AWD VEHICLES - SHUDDER/CHATTER/VIBRATION ON TURNS OR THUMP/CLUNK NOISE ON LIGHT ACCELERATION - BUILT 10/1/2009 TO 12/31/2009


and thank you for the welcome.

Interesting. Since that TSB applied to a very limited span of production dates, I doubt that it applies as-is to the 2012. However, there's nothing saying you couldn't have a unique issue that isn't widespread over the 2012 model year. You could try the checks listed in that TSB to see if your car behaves in either of those ways.

Is your 2012 still under warranty?

What was the outcome? I have a similar issue on my 2013 SHO (with 3K miles), but my car is suspension lowered and modded so I've been trying to avoid bringing it in to avoid the drama. Its pretty annoying to me, the passengers dont seem to care or be bothered by it.
