I mortgaged my car to Huitong Xincheng Leasing Co., Ltd., and I never paid back the first installment. Now the credit report shows overdue. What will happen to illegal accounts?

Generally speaking, small loan companies or small loan leasing companies are not on the credit information system. However, after investigation, the controlling shareholder of the company you mortgaged is China Shengda Automobile Service Co., Ltd., which is relatively strong, thus affecting your credit information. However, for the specific analysis of specific problems, you only provided the information that "the down payment has not been repaid", and you need to provide more information in the future to judge whether you are a black household.
