Cancel an extended car warranty or dealer add-on by mail

• Many auto add-ons are separate optional products, not requirements for getting an auto loan.
• Your cancellation address may be an administrator, insurer, provider, dealer, lender, or address printed inside the contract.
• A useful cancellation packet includes the contract number, VIN, buyer details, requested refund handling, signature, and supporting copies.
• Certified Mail helps create a mailing record when you need to show what was sent and when.
• PostalForm prepares and mails the packet you review. It does not decide eligibility, calculate refunds, or guarantee a provider response.

Use this packet when you need to mail a written cancellation or refund request for a dealership add-on, including:

• Extended warranty or vehicle service contract
• GAP product or GAP waiver
• Prepaid maintenance plan
• Tire-and-wheel coverage
• Appearance, paint, fabric, or protection package
• Key replacement coverage
• Theft protection or etching product
• Another finance-and-insurance add-on listed in your purchase documents

The workflow is designed for a practical job: generate a signed written request, attach copies of the documents that identify the product, and mail the packet with proof.

Before you send a cancellation request, pull the paperwork you received at the dealership and look for:

• The contract or product administrator name
• The contract, policy, or agreement number
• The cancellation section
• The cancellation mailing address
• Any required cancellation form
• Any odometer statement or mileage requirement
• Whether the refund goes to you directly or to the auto loan balance

The CFPB notes that products such as extended warranties and GAP are generally optional in auto lending, and the FTC explains that auto service contracts can be sold by dealers or independent companies and can cost hundreds or thousands of dollars. That is why the administrator details matter: the selling dealer is not always the entity that processes the cancellation.

A strong cancellation letter should be boring, complete, and easy to process. Include:

• Your full name and mailing address
• Phone and email, if you want the administrator to contact you
• Vehicle year, make, model, VIN, purchase date, and current mileage
• Product type and provider or administrator name
• Contract, policy, or agreement number
• Selling dealer name
• Lender name and loan number, if the product was financed
• Clear cancellation request
• Requested effective date, if you have one
• Refund handling preference, such as direct refund, loan credit, or written refund calculation
• Request for written confirmation
• Signature and date

Avoid turning the letter into a long complaint. The packet can include a short facts section, but the core request should be direct: identify the product, cancel it, ask for confirmation, and ask for the refund or loan-credit calculation.

Do not mail originals unless the administrator specifically requires them. In most cases, copies are safer for your records.

Useful attachments include:

• Contract or add-on agreement pages
• Buyer's order, purchase agreement, or retail installment contract pages showing the add-on charge
• Odometer statement or mileage photo if requested
• Provider cancellation form if one exists
• Dealer, lender, or administrator correspondence

PostalForm's workflow adds these behind the generated letter and creates an exhibit index so the recipient can see what is included.

Certified Mail is useful when the value is not just delivery. It is the record. A car add-on cancellation can involve a dealer, lender, administrator, and refund accounting trail. If anyone later says the request was not received or did not include enough information, your mailed packet and tracking record give you a factual starting point.

PostalForm requires Certified Mail for this packet because the product is built around written proof. You can also add separate Certified Mail copies to the dealer or lender when you want those parties to have the same packet.

1. Choose the product being canceled: vehicle service contract, GAP, prepaid maintenance, tire-and-wheel, appearance protection, key replacement, theft protection, or other add-on.
2. Enter buyer, vehicle, contract, provider, dealer, lender, and cancellation address details.
3. Add refund handling, confirmation request, and a follow-up date for your own records.
4. Upload optional contract pages, buyer paperwork, odometer proof, provider forms, or correspondence.
5. Preview the generated cancellation packet before checkout.
6. Mail it with Certified Mail proof, including optional dealer or lender copy recipients.
