Jan.’06 for me, and my left front strut is being replaced due to leak.
I did see a lengthy thread on an LS2 forum about a number of Jan/Feb cars that seem to be affected. People are also urged to file complaint reports:
Go to
www.nhtsa.gov
click on "Vehicles & Equipment"
click on "Recalls/Defects"
click on "File a Complaint" and complete the form.
