I have seen this same scam listed on the internet over the past few months.  A prerecorded message tells my that my warranty is about to expire and it is very forceful that I urgently need to press #1 to speak with a representative.  They indicate that they have send information in the mail as well.  My car is way too old to have a warranty.  They have probably called 4-5 times in the last month or so.
