If you found mechanical issues or other defects with the new vehicle purchased with a CEO auto loan, there is nothing we can do as your lender.
You should contact the dealership or seller to see if they will accept a return or exchange it for a different vehicle. If they work with you to initiate a refund or exchange for a different vehicle, CEO can determine how to proceed with the financing.
Please review your sales contract or purchase agreement to confirm your rights to cancel the transaction. You may also review the vehicle's service contracts and extended warranties if available. Contact your financial coach if you require additional ideas or support.
