I just received a call from this number as well, I bought a new car from Honda last year and right after one year mark, they started to calling me as soon as my car hit a year mark. I told them not to call me but they keep calling me and I googled the number and this came up. I blocked this number as well.
Called me today on my cell. Didn't leave a message. Wouldn't be surprised if its car warranty, as the car dealer is one of the few people who have my cell number. Plus I am inundated with junk mail regarding my car as well (I can't tell you how many "final notice" mails I've received.
