The American Express Platinum Card includes rental car damage coverage, but it works as a secondary insurance and only covers collision and theft — not liability or medical payments

The Amex Platinum's rental car benefit, called Rental Car Damage Liability Coverage, reimburses you for physical damage to a rental vehicle if you cause an accident or the car is stolen. It does not cover injuries to other people, damage to their property, or medical expenses — those gaps mean you cannot rely on it as your only insurance when renting.

The coverage is secondary, meaning your personal auto insurance or the rental company's insurance pays first. Amex reimburses you only for costs your primary insurance does not cover, up to the card's limit. If you do not have personal auto insurance, Amex coverage becomes primary, but this is not a substitute for a real policy.

The card covers rentals up to 31 consecutive days in most cases, and it applies whether you rent in the United States or abroad. You must decline the rental company's damage waiver and charge the full rental to your Amex Platinum card for the coverage to activate.

Key Takeaways

  • Amex Platinum covers collision damage and theft to rental cars, but only as secondary insurance after your personal policy pays.
  • The coverage does not include liability (injuries or damage to others), medical payments, or personal belongings inside the car.
  • You must decline the rental company's damage waiver and pay the entire rental with your Amex Platinum card for coverage to apply.
  • Coverage limits and exclusions vary by card version and country, so confirm the current terms with Amex before renting.
  • If you have no personal auto insurance, the Amex benefit becomes primary, but it is not designed to replace a full policy.

What damage the Amex Platinum actually covers

The card covers physical damage to the rental vehicle from collision, theft, vandalism, and weather events like hail or flooding. If you hit another car and cause damage to the rental, Amex reimburses your deductible and repair costs up to the policy limit. If the rental is stolen, the coverage applies to the full value of the vehicle.

The coverage also includes damage from hitting an animal, rolling the vehicle, or damage from falling objects. It does not cover wear and tear, mechanical breakdown, or damage from off-road driving or racing.

What the Amex Platinum does not cover

Liability coverage — the most important part of any car insurance — is not included. If you cause an accident that injures someone or damages their property, the Amex card does not pay for their medical bills, lost wages, or vehicle repairs. This is why you cannot use Amex coverage alone.

Medical payments are also excluded, so if you or your passengers are injured in an accident, Amex does not cover hospital bills or treatment. Personal belongings left in the car — luggage, electronics, cash — are not covered if they are stolen or damaged. Roadside assistance like towing or lockout service is not included either.

The card does not cover rental cars used for commercial purposes, racing, or off-road driving. It also does not apply if you rent a vehicle in a country where Amex does not operate, though coverage is available in most developed nations.

How secondary insurance actually works in practice

When you file a claim, you first submit it to your personal auto insurance. Your insurer pays for covered damage up to your policy limit and deductible. Then you submit the same claim to Amex with documentation showing what your personal insurance paid and what you still owe.

Amex reimburses the remaining balance, up to its coverage limit. If your personal insurance covered the entire cost, Amex owes nothing. If you have no personal auto insurance, you submit the claim directly to Amex, and they pay as the primary insurer — but this scenario is rare and not recommended.

The process typically takes several weeks. You will need the rental agreement, police report (if applicable), repair estimates or invoices, and documentation from your personal insurer showing what they paid.

The rental company's damage waiver versus Amex coverage

When you rent a car, the rental company offers a damage waiver (also called Loss Damage Waiver or LDW) that removes your financial responsibility for damage. This waiver costs $15 to $30 per day and is the rental company's own insurance.

If you have Amex Platinum coverage, you should decline the rental company's waiver. Paying for both is redundant and wastes money. By declining the waiver and charging the rental to your Amex card, you activate the card's coverage instead.

The exception is if you have no personal auto insurance and no other coverage. In that case, buying the rental company's waiver is safer than relying solely on Amex, because the waiver covers liability and other gaps that Amex does not.

Coverage limits and what they mean for you

Amex Platinum typically covers up to $50,000 in damage per claim, though the exact limit depends on your card version and the country where you rent. Some versions cap coverage at $75,000. Check your card's benefits guide or call Amex before renting to confirm the current limit.

For most rental cars, $50,000 is enough to cover collision damage and theft. A typical mid-size rental costs $20,000 to $30,000, so the limit covers full replacement. However, if you rent a luxury vehicle or a large SUV, the replacement cost could exceed the limit, leaving you responsible for the overage.

The limit also applies per claim, not per year, so multiple accidents or thefts during the year do not reduce your coverage for future rentals — as long as each incident is a separate claim.

When your personal auto insurance is the better choice

If you already have personal auto insurance, your policy almost always provides better coverage than Amex Platinum. Your personal policy includes liability, medical payments, and uninsured motorist protection — all things Amex does not cover.

Your personal insurance also covers damage to rental cars without requiring you to decline the rental company's waiver or jump through claim hoops. You simply file a claim with your insurer, just as you would for your own vehicle.

The only reason to use Amex coverage is if your personal policy excludes rental cars (rare) or if you are renting in a country where your personal insurance does not apply. In most cases, your personal auto insurance is simpler and more complete.

Steps to take before and after renting with Amex coverage

Before you rent, call Amex or check your online benefits guide to confirm the current coverage limit, any geographic restrictions, and whether your card version includes rental car coverage. Some Amex cards do not offer this benefit, so verify yours does.

When you arrive at the rental counter, decline any damage waiver or insurance offered by the rental company. Tell them you have your own coverage. Make sure the rental agreement clearly states that you declined their waiver.

Charge the entire rental cost to your Amex Platinum card. If you pay with a different card or method, the Amex coverage does not apply.

If you are in an accident or the car is damaged, report it to the rental company immediately and get a written damage report. Take photos of the damage and get contact information from any other drivers involved. Then report the incident to your personal auto insurance (if you have it) and follow their claims process.

Once your personal insurer settles the claim, gather all documentation — the rental agreement, damage report, repair invoices, and your insurer's payment letter — and submit it to Amex along with a claim form. Amex will reimburse any remaining balance up to their limit.

Frequently Asked Questions

Do I need to buy the rental company's insurance if I have Amex Platinum?

No, if you have personal auto insurance. Decline the rental company's waiver and use your personal policy as primary, with Amex as secondary backup. If you have no personal insurance, buying the rental company's waiver is safer because it covers liability, which Amex does not.

Does Amex Platinum cover liability if I cause an accident?

No. Amex covers only physical damage to the rental car itself. If you injure someone or damage their property, you need liability coverage from your personal auto insurance or the rental company's waiver. This is a major gap in Amex coverage.

What happens if I rent a car and don't charge it to my Amex card?

The Amex Platinum coverage does not apply. You must charge the full rental cost to your Amex Platinum card for the benefit to activate. Paying with a different card, cash, or check means you lose the coverage.

Can I use Amex Platinum coverage if I rent a car in another country?

Coverage is available in most countries where Amex operates, but some regions and specific countries are excluded. Call Amex before renting internationally to confirm coverage applies where you are traveling.

How long does it take to get reimbursed from Amex after an accident?

The process typically takes four to eight weeks after you submit all documentation. Your personal insurer settles first, which can take two to four weeks, then Amex processes their portion. Having all documents ready — rental agreement, damage report, repair invoices, and your insurer's payment letter — speeds up the process.
