The National Automobile Dealers Association (NADA) has asked the U.S. government to suspend the Cash-for-Clunkers program immediately as it believes the $3 billion in earmarked funds have already been used up.

NADA Chairman John McEleney told Automotive News that based on a survey of its dealers it believes the $3 billion in funding could be used up as of today. But according to the Transportation Department, only 411,624 claims have been filed, accounting for a total of $1,72 billion. The difference says McEleny is due to rejected claims that have yet to be re-submittted.

Transportation Secretary Ray LaHood, has said that the $3 billion should last until Labor day, but NADA’s track record is also pretty good, as the group was the one to raise the alarm that the initial $1 billion in funding, intended to run for several months had dried up in just two weeks.

Earlier in the week LaHood said that the Transportation Department is readying a plan to wind-down the Cash-for-Clunkers program, commenting that even if the fund dries up, the dealers will still be reimbursed.
