CarMax Warranty: MaxCare Plans, Claims and Cost

One $4,000 transmission repair can erase every dollar you saved buying used. A carmax warranty actually comes in two layers: the free 90-day/4,000-mile limited warranty included with every vehicle CarMax sells, and MaxCare, the optional extended service plan that can stretch protection up to 5 years or 150,000 miles.

This guide explains what each layer covers, what MaxCare costs, how deductibles work, what’s excluded, and exactly how to file a claim that gets approved.

Quick Answer: CarMax Warranty at a Glance

Every CarMax car ships with a free limited warranty of 90 days or 4,000 miles covering major systems. MaxCare is the optional extended service plan — available only at the time you buy the car — with terms up to 5 years/150,000 miles, deductibles from $50 to $600 per visit.

MaxCare covers the engine, transmission, drivetrain, steering, suspension, cooling, electronics, and climate control. You can service the car at any licensed repair shop in the US; the shop calls 800-519-1511 for authorization before work begins.

CarMax Limited Warranty vs. MaxCare: What’s Free

Before MaxCare enters the picture, every CarMax vehicle includes a free limited warranty: 90 days or 4,000 miles of coverage on major systems such as the engine, transmission, drivetrain, and steering. Several states mandate longer free coverage — Connecticut, Massachusetts, Minnesota, New Jersey, New York, and Rhode Island — so check your state’s minimums at signing.

CarMax also gives every buyer a 30-day money-back guarantee (up to 1,500 miles): return the car for any reason within that window. That guarantee is separate from the warranty — it covers buyer’s remorse, while the limited warranty covers mechanical breakdowns.

MaxCare picks up where the free limited warranty ends. It is an extended service plan, not insurance, and it must be purchased at the same time as the vehicle. There is no option to add MaxCare weeks or months later, which is the single most misunderstood rule in the entire carmax warranty lineup.

What Does MaxCare Cover?

MaxCare is a stated-component carmax warranty service contract: it lists the systems it covers, and nearly everything mechanical inside those systems is included. The headline coverage areas are the engine, transmission, drivetrain, steering, suspension, cooling system, electrical and electronics, and climate control.

Coverage applies at any licensed repair facility in the United States — you are not limited to CarMax service centers. The repair shop must call the plan administrator at 800-519-1511 for authorization before starting work, which is how most claims are approved or denied.

What MaxCare Does Not Cover

The exclusions decide which claims get paid. Read these before you buy:

• Excluded Tires and wheels. Tires, wheels, and tire damage of any kind are never covered.
• Excluded Brake pads, rotors, and wear items. Friction wear parts — brake pads and rotors, belts, hoses, wiper blades, filters — are excluded as normal wear.
• Excluded Routine maintenance. Oil changes, alignments, tune-ups, and scheduled services are your responsibility.
• Excluded Cosmetic and body damage. Paint, dents, upholstery, glass, and trim are excluded.
• Excluded Pre-existing conditions. A 30-day/1,000-mile clause excludes problems that existed or were developing before your purchase date.
• Excluded Aftermarket modifications. Failures caused by non-factory modifications or performance parts are excluded.
• Excluded Commercial use. Vehicles used for commercial purposes (rideshare, delivery fleets) are excluded unless the contract says otherwise.

How Much Does MaxCare Cost?

CarMax does not publish a national MaxCare price list — the price is set per vehicle based on make, model, age, mileage, term length, and your chosen deductible. 2026 sample quotes from buyer reviews cluster between $1,000 and $4,000: roughly $1,559–$1,839 for a mainstream sedan like a 2020 Camry with 30,000 miles on a 5-year/75,000-mile term, and up to $3,900+ for luxury or high-risk models.

Two pricing rules work in your favor. First, CarMax’s no-haggle policy applies to MaxCare too — the quote is the quote, which removes dealer mark-up games. Second, choosing a higher deductible ($400 or $600 instead of $50) lowers the plan price significantly. If you finance the car, the MaxCare cost can be rolled into your monthly payment.

Do the break-even math on your carmax warranty before signing: a $2,100 plan that covers one $3,500 transmission repair has paid for itself. On a reliable low-mileage car you plan to sell in two years, the same $2,100 may never come back.

MaxCare Deductibles Explained

You choose one deductible at purchase — $50, $200, $400, or $600 — and pay it once per repair visit, not per part. If the shop replaces your alternator and water pump in the same visit, you pay the deductible once.

The deductible is waived when you have the work done at a CarMax service center on qualifying plans, which effectively makes CarMax repairs $0 out of pocket beyond the plan price. At independent shops, you pay your chosen deductible and MaxCare pays the shop directly for the covered balance.

Pick the deductible on your carmax warranty against your emergency fund, not your optimism: a $600 deductible saves money up front but stings on a surprise repair, while the $50 option costs more at signing and almost nothing at the counter.

How to File a MaxCare Claim

1. Take the car to any licensed repair shop — a CarMax service center, a dealer, or an independent ASE-certified facility.
2. Describe the symptom, not your diagnosis. Say “the transmission slips between second and third,” not “the transmission needs a rebuild.”
3. The shop calls 800-519-1511 for authorization before starting work. This step is mandatory — unauthorized repairs are not reimbursed.
4. Pay your deductible when the work is approved. MaxCare pays the shop directly for the covered portion.
5. Keep every invoice. If a related part fails later, your paper trail proves the repair history.

Claims cannot be filed online — authorization happens shop-to-administrator by phone. For 24/7 emergency roadside assistance (towing, jump-starts, lockout service, fuel delivery), call 1-800-693-5324.

Can You Transfer or Cancel MaxCare?

Yes to both. If you sell the car before the plan expires, your carmax warranty can be transferred to the new owner for a transfer fee — a transferable service contract is a genuine selling point in a private-party listing. If you’d rather walk away, you can cancel the plan for a pro-rated refund based on unused time or mileage.

Read the cancellation math in your contract before you sign: early cancellation refunds are pro-rated, and administrative fees may apply. Transfer eligibility and fees vary by contract, so confirm the exact terms with CarMax at purchase.

MaxCare Roadside Assistance

Every carmax warranty MaxCare plan includes 24/7 emergency roadside assistance anywhere in the US: towing to the nearest qualified repair facility, battery jump-starts, flat-tire assistance (mounting the spare — not replacing the tire), lockout service, and fuel delivery (the service call is covered; the fuel itself is not). One number covers it all: 1-800-693-5324.

CarMax Warranty FAQs

Conclusion

For most used-car buyers, the carmax warranty decision comes down to timing and the car itself: the free 90-day/4,000-mile limited warranty covers the shakedown period, and MaxCare — the paid carmax warranty layer bought only at purchase — extends major-system protection up to 5 years or 150,000 miles with deductibles from $50.

The honest trade-offs: no published pricing, no adding it later, and exclusions on tires, brakes, maintenance, and pre-existing issues. If your car has expensive failure modes and you’ll keep it for years, MaxCare’s one-claim-can-pay-for-it math is compelling.
