One-time payment: Sign in for full payment controls or use Pay as Guest for an eligible same-day payment.
Lost or stolen card: Call the number on your statement or current cardholder support immediately and use Synchrony’s lost-or-stolen-card option.

Unauthorized account or identity theft: Call Synchrony fraud support at 1-866-834-3205. For an existing Synchrony fraud case, call 1-866-412-7866.
Merchant refund, defective work, or service complaint: Contact the merchant first, then contact Synchrony if the charge or credit remains disputed.
Promotional-financing or interest question: Review the Promotional Purchase Summary on the statement and ask Synchrony to explain the balance, expiration date, and payment allocation.

Where the card is accepted: Use the Synchrony Car Care location finder.

Privacy and scam warning: Never post a full card or account number, Social Security number, bank information, PIN, CVV, password, one-time security code, statement, fraud-case number, home address, or identity document in a public review. Go directly to Synchrony.com or use the number on your card or statement. Do not trust an unexpected caller, text, email, search advertisement, or social-media account asking for payment by gift card, cryptocurrency, wire transfer, or remote access to your device.

What Happened to the CarCareONE Credit Card?

Synchrony launched the Synchrony Car Care Credit Card in 2017 as the replacement for the CarCareONE card. The program continued under the new name, with Synchrony Bank as issuer and servicer. An older card, statement, merchant sign, credit report, or search result may still use CarCareONE. Use the current cardholder number, latest statement, or Synchrony account directory rather than an archived telephone number or mailing address.

How to Log In and Pay a Car Care One Account

Use Synchrony’s account manager to register or sign in. Online access can show balances, due dates, statements, transactions, promotional balances, alerts, and payment options. The MySynchrony app also supports eligible Synchrony-issued cards.

Pay as Guest supports an eligible same-day payment without signing in; registered cardholders can schedule up to 12 future payments. Save the confirmation and verify that the payment posts. If a payment is missing, call promptly with the date, amount, and bank confirmation. Use the current statement for mailed payments because payment and billing-dispute addresses may differ.

Lost Cards, Unauthorized Charges, and Billing Disputes

Report a lost or stolen card and unauthorized transactions promptly. Call the number on the statement or current cardholder support. Synchrony’s fraud route is 1-866-834-3205; for an existing fraud case, call 1-866-412-7866. Keep the merchant name, transaction date, amount, and a list of charges you recognize.

For defective repairs, returned parts, or a missing merchant refund, contact the merchant first and save the invoice, work order, warranty, refund receipt, and messages. If unresolved, ask Synchrony which dispute route applies.

For a possible billing error, follow the written instructions on the statement. A written notice generally must reach the issuer within 60 days after the first statement showing the error to preserve federal rights. Continue paying undisputed amounts as required and keep copies.

How Synchrony Car Care Promotional Financing Works

Synchrony currently advertises deferred-interest financing on qualifying purchases of $199 or more: no interest if the promotional balance is paid in full within six months. The qualifying amount generally must appear on one receipt, and gas purchases are not eligible.

This is deferred interest, not an automatic interest-free installment plan. If the full promotional balance is not paid by the expiration date, interest can be charged from the purchase date, and minimum payments may not be enough. Check each statement’s Promotional Purchase Summary for the balance, accrued deferred interest, and deadline. Ask Synchrony how payments are allocated when multiple balances exist, and rely on the current agreement because terms can change.

Where Can the Synchrony Car Care Card Be Used?

Synchrony says the card is accepted at more than one million automotive merchant locations nationwide, subject to the merchant’s acceptance and merchant category code. Examples on the current card page include gas stations, auto-parts stores, repair and service businesses, tires, routine maintenance, car washes, parking, tolls, rideshare and taxi services, rental cars, and some auto-insurance payments.

Acceptance does not mean every purchase receives promotional financing. Confirm both before authorizing a large expense, and use Synchrony’s location finder rather than an old CarCareONE merchant list.

Account Changes, Credit Limits, and Rebate Questions

Sign in to update contact details and alerts. For a legal name change, call 1-866-657-0376. Eligible cardholders can request a credit-limit increase, but approval is not guaranteed. For a Synchrony Car Care rebate, call 1-866-419-4001. Rebates cannot be used as card payments.

How to Escalate an Unresolved Complaint

Start with cardholder service and identify the issue: payment, interest, promotion, fraud, dispute, credit reporting, or account access.
Record the date, representative, case number, promised action, and follow-up date. Save relevant records.
For a billing error, use the written notice address and instructions on the current statement. Do not send a dispute letter only to a payment address.

For incorrect credit-report information, dispute the item with the credit bureau and Synchrony, keeping copies of the report and supporting records.
If direct escalation does not resolve a consumer-financial issue, consider submitting a complaint through the Consumer Financial Protection Bureau.
