XU , thanks for the number info. Mine went in to the dealer yesterday and was out by noon. They performed revision "D" of the trail of bulletons ( re-adjust lash , lock-tite , reprogram the SAS module) and it actually seems to have corrected the issue back to " like new " feel. I think that was a good hold-over till the new parts are more available. The jury is still out ,time will tell if it loosens up again as there's plenty of warranty time left.
