Thank you for your interest in consolidating your car loans with USAA. I do want to let you know, USAA does not have an option to consolidate car loans. What this means to you is USAA can only finance 1 car per loan. Another option you might want to consider is refinancing your vehicle. If you already have a loan with us, you'll need to call to submit a new loan application. If your car loan is with another financial institution, you can apply online at anytime to see if you qualify for refinancing your vehicle with USAA. To apply online, simply go to Products, then choose Auto Loans, then scroll down to click on Refinance. I would recommend obtaining a payoff quote from your current lender so you'll know how much you'll need to apply for. If you have any other questions, please feel free to call us at 1-800-531-8722 or 210-531-8722 or #8722 from a mobile device. Our normal business hours are Monday - Friday 5:00 a.m. to 12:00 a.m. CT; Saturday 6:00 a.m. to 10:00 p.m. CT and Sunday 8:00 a.m. to 6 p.m. CT.
