“A great credit score is only a part of the formula lenders use to approve a car loan application. So even though your 814 credit score is awesome, you might have some other issues.
You say you already have another car loan, so you might have a debt-to-income ratio that’s too high (higher than 43% is too much for approval). Alternatively, your loan-to-value rate might be too high. Either way, the lender feels like the risk is too great to grant you another loan.
You can shop around with other lenders to get a second loan, or you can just look for a car that’s a bit cheaper and fits your budget.”
