@Col Jack 1, I understand that you wish to cancel your loan application. The application will automatically be removed from your account summary page when the offer expires 45 days from the date you were approved.
If you'd like to permanently withdraw or discontinue your loan application, you may do so by following these steps:
Select the Products tab.
Under Banking, select "Auto Loans."
Scroll down to "Get Started", from the drop down, choose "Finance an Auto Purchase" or "Refinance an Auto Loan."
Select "View Saved Applications."
Select "Remove" and then "Yes."
I hope this information helps. - Ben
