Can a car dealer refuse pymnt if your already behind?

In general, dealerships are not obligated to accept a partial payment if the customer is already behind on their car payment. They may request the customer to pay the full outstanding amount or face repossession of the vehicle. However, it's important to note that the specific policies regarding partial payments and repossession may vary depending on the dealership, the state in which you are located, and the terms and conditions of your purchase contract. It's best to contact the dealership directly to discuss the situation and see if there are any options available to partially settle the payment and avoid repossession.
