No ID. No voicemail

This number just called me. A female voice said she was with Nissan and was calling about my warranty on my car. She knew my car's year, make, and model. I asked her what dealership she was calling on behalf of and she paused a moment, then said that dealerships are privately owned and that she worked for Nissan. I told her that my car warranty was still active for 4 more years and hung up.  I think this is a scam to get people to pay for those junk insurance policies for when your car breaks down. I could hear many other telemarketers in the background too.

No message

This number just called me, saying that the send several notice to me (which I never received) about my warranty is going to expire and this is the last time they will reach you and they directly want your card info, definitely spam.

Spam about cars. Strange she knows the make, model and year of my car. Who leaked the info?
