Notice of warrant expiration

The postcard says that my factory warranty has expired.  The claim to have my owner identification number which is also a crock.  They say that my 2008 factory warranty has expired.  From what I understand it is three years or 36,000 miles or which ever comes first.  These scam artists need to a better job in researching their so called information.  My notice also has the address of 3710 Muller Road, St. Charles, MO 63301.  Thanks for the information from the person who wrote in 2007.  I do appericate someone out there who is still honest.
