<prompt> Human: Im in CA.In July I bought a 2016 car. Down payment of a few thousand given as a personal check.Car was financed through a credit union.Ive been wondering lately why they havent cashed my down payment check, and the other day I received a text from someone at the dealership saying they are having trouble locating the check and do I remember how I paid for the down payment.Just curious if they cant find the check and dont cash it within a few months, do I have any obligation to get them another check?Not gonna do that, just got me curious what happens in that situation. Seems kind of scary that a dealership can just lose a large amount of money like that.  <response>: Just curious if they cant find the check and dont cash it within a few months, do I have any obligation to get them another check?Of course you do. Call you bank, have a stop payment put on the check, and write them a new check. Or be prepared to turn the car back over to them and go to a new dealership.
