NEW YORK (AP) -- A New York senator is asking for an investigation into the spam phone calls pitching bogus car warranties that many Americans receive several times a day.

Sen. Charles Schumer says the scam artists are using random call generators allowing them to contact people who are on the "do not call" list.

The calls feature a recorded voice saying that the warranty on your vehicle "is about to expire" -- whether you own a vehicle or not.

Schumer said Sunday that he received one of the calls on his cell phone last week. He is asking the Federal Trade Commission to investigate the calls.

Alison Southwick of the Better Business Bureau says that her agency received more than 140,000 complaints about car warranty calls in 2008.
