Having a bad credit doesn’t prevent you from getting an auto loan. The problem is that you will pay more. If you are with good credit score, auto loan rates starts at 1.99%. If you are with bad credit, it wouldn’t be possible to qualify for this rate.

If you already have an auto loan and want to refinance it with cheaper one, the best strategy is to always work on your credit score and apply for new auto loans every few months. That way you always can find better options.
