Key Takeaways
- Costco car insurance is underwritten by American Family through its CONNECT subsidiary — your policy is an American Family product with a member discount layered on top, not a separate Costco product with unique underwriting.
- The member discount is real, but ‘discounted’ doesn’t mean cheapest. Drivers with clean records in competitive ZIP codes routinely find lower car insurance rates elsewhere even after the Costco discount applies.
- Executive Members get better pricing than Gold Star members — if you’re already an Executive Member for warehouse savings, the incremental insurance benefit costs you nothing extra to access.
- CONNECT is not available in every state. Confirm availability in your state before treating this as a live option, because coverage gaps are not publicized prominently on the Costco member portal.
Costco car insurance is not a separate insurance product. It’s American Family Insurance, sold through a subsidiary called CONNECT, with a negotiated member discount applied on top. That distinction matters, because it tells you exactly what you’re evaluating: an American Family policy at a price Costco members can’t get by calling American Family directly.
This review draws on CONNECT’s published policy documents, American Family’s publicly filed rate information, and aggregated user reports from Reddit, Trustpilot, and the BBB. No quote-flow data was used in this analysis.
What Costco Car Insurance Actually Is
CONNECT by American Family launched as the dedicated affinity insurance platform for Costco members. American Family built it to keep the Costco book of business separate from its standard retail channel, which matters operationally: CONNECT has its own branding, its own website, and its own call center. But the paper behind every CONNECT policy is American Family paper, which means American Family’s underwriting guidelines, American Family’s claims department, and American Family’s AM Best financial strength rating of A (Excellent).
Costco earns a referral fee for directing members to CONNECT. That’s the structure. It’s a common affinity arrangement in insurance, similar to how alumni associations or credit unions negotiate group rates with carriers. The benefit is real, Costco has negotiating leverage, but you should understand the relationship before assuming ‘Costco-backed’ means something about how a claim gets handled.
How the Member Discount Works
Gold Star Costco members receive a discount off CONNECT’s standard rates. Executive Members, who pay roughly $130 per year versus $65 for Gold Star, receive a deeper discount. CONNECT does not publish the exact percentage publicly, which is a deliberate choice. Rate discounts negotiated through affinity arrangements are proprietary, and carriers file them with state insurance departments without requirement to advertise them.
What this means practically: if you’re already an Executive Member because you shop at Costco regularly, the insurance discount costs you nothing incremental to access. If you’re a Gold Star member considering an upgrade to Executive specifically to get a better insurance rate, run the math first. The $65 annual upgrade cost needs to be recovered by the additional discount on your premium, and that calculation depends on your specific rate.
The discount also applies at renewal, not just at the initial quote. That’s worth knowing, because some affinity programs front-load discounts to win the business and then quietly normalize rates at renewal. CONNECT’s discount is tied to active membership status throughout the policy term.
Coverage Options
CONNECT offers standard personal auto coverage: liability, collision, comprehensive, uninsured/underinsured motorist, medical payments, and personal injury protection where state law requires it. There’s nothing proprietary about the coverage menu, these are the same building blocks you’d find on any American Family retail policy.
A few options are worth calling out specifically. New car replacement coverage, available on vehicles typically within the first year of ownership, pays the cost of a new vehicle of the same make and model rather than the depreciated actual cash value. Rental reimbursement and roadside assistance are available as add-ons. Gap coverage, which pays the difference between what you owe on a loan and what the car is worth at total loss, is offered through CONNECT, though the terms deserve a close read before you waive it from your lender.
CONNECT also participates in American Family’s KnowYourDrive telematics program. The program tracks driving behavior through a mobile app: hard braking, acceleration, speed, and time of day. Enrollment typically comes with a small upfront discount. The part carriers leave out of the brochure is that KnowYourDrive’s data feeds into your renewal rate, and drivers with poor telematics scores have seen increases at renewal. If you drive late at night regularly, commute in stop-and-go traffic, or have anyone under 25 on the policy who might use the vehicle, think carefully before opting in.
Geographic Availability: The Problem No One Leads With
CONNECT is not a national product. American Family’s operating footprint skips several states entirely, including most of New England and parts of the South. As of mid-2026, the carrier writes personal auto in roughly 19 states, concentrated in the Midwest and West where American Family has historical market presence.
Costco’s membership portal doesn’t make this limitation obvious. Members in ineligible states sometimes spend time on a quote before learning CONNECT won’t write them. Check availability before you commit time to the comparison process. The CONNECT website will tell you immediately if your state is covered.
The Bundle Angle
If you’re a Costco member considering homeowners insurance, CONNECT offers home and auto through the same platform. American Family’s home underwriting applies, with the same membership discount structure. The multi-policy discount for bundling is real and stacks on top of the member discount.
That said, bundling with any single carrier involves a trade-off. You simplify billing and get a discount, but you give up the ability to shop each line independently. A homeowner who finds a significantly better home rate elsewhere would have to give up the bundle discount on both policies to switch. Get the bundled quote, then check best car insurance options separately for each line before deciding the bundle actually wins on total cost.
What the Rate Filing Says vs. What the Marketing Says
American Family files its rates with state insurance departments, and those filings are public records, though they require some effort to obtain. The consumer-facing story from CONNECT is that Costco’s buying power translates directly to lower premiums. The filing-level story is more granular: the Costco discount is a percentage modification applied to American Family’s approved base rates, and those base rates vary significantly by state, territory, and driver profile.
In states where American Family competes aggressively on rate, the combination of their base pricing plus the Costco discount can produce a genuinely competitive quote. In states where American Family is a second- or third-tier competitor on price, the discount gets you to a better version of their rate, but not necessarily to the cheapest rate in the market.
I saw this pattern repeatedly when I worked the desk at an independent agency. Affinity discounts feel like a floor, like you’ve already negotiated the best deal before you walk in. What they actually are is a reduction from one carrier’s specific starting point. A 10% discount on a rate that’s 20% higher than a competitor’s standard rate isn’t a win.
What Real Users Report
Across several hundred user reports on Reddit and Trustpilot, two patterns recur consistently. The first is positive: CONNECT’s customer service gets high marks for accessibility, and policyholders report that the Costco relationship makes it easier to reach someone than dealing with a large carrier directly. The second is more complicated: claims handling gets mixed reviews, with a recurring complaint about estimates coming in below independent shop assessments on collision repairs. That’s not unique to CONNECT or American Family, but it’s a consistent enough pattern in the user reports to note.
BBB complaints for CONNECT, which files separately from American Family’s main entity, are modest in volume and skew toward billing disputes and cancellation issues rather than claims denials. That’s a relatively clean complaint profile for a carrier of its size.
How CONNECT Rates Compare
Published rate comparisons for the same driver profile show CONNECT is competitive for certain demographics. A 40-year-old homeowner with a clean record, good credit, and a mid-range vehicle is close to the market median in states where American Family prices aggressively. That profile benefits most from the CONNECT structure.
The value proposition erodes for young drivers, drivers with recent violations or claims, and drivers in urban ZIP codes where carriers compete hard. GEICO, Progressive, and regional carriers in many markets will undercut CONNECT’s best rate for those profiles. Checking car insurance rates across multiple carriers before settling on CONNECT isn’t optional, it’s the only way to know if the member discount is actually translating to the lowest premium available.
Executive Members with clean records who already pay the $130 annual fee have the best shot at a genuinely competitive outcome. The math works for them because the larger discount comes at no additional membership cost.
Who Should Use CONNECT and Who Shouldn’t
CONNECT is worth a serious quote if you’re an active Costco member, especially an Executive Member, who already had American Family on your comparison list. The discount is real, the financial backing is solid, and the home plus auto bundle is a legitimate simplification if both lines end up priced well.
It’s the wrong starting point if you’re a young driver, have a recent at-fault accident, or live in a state where American Family’s base rates aren’t competitive. The member discount doesn’t change the underlying rate philosophy; it adjusts it by a fixed percentage. Starting from a higher base still lands you above the market in those cases.
Drivers outside CONNECT’s operating states don’t have a decision to make. The product isn’t available to them, and the Costco portal should tell them that clearly before they invest time in a quote.
The Recommendation
Get the CONNECT quote. If you’re a Costco member, it takes ten minutes and you’re entitled to a discounted rate that non-members can’t access through American Family’s retail channel. But don’t stop there. Run the same coverage parameters through at least two or three competing carriers before making a decision. The member discount is a discount off one carrier’s rate, not a guarantee of the lowest premium available. For most Costco members, the CONNECT quote will land somewhere in the competitive middle of the market. For some, it’ll be the winner. You won’t know until you compare.
