    Are Extended Warranties Worth It For High-Mileage Cars?

    Unless you have savings set aside to cover car repairs, extended warranties can be worth it for high-mileage cars. Once your car passes 100,000 miles, any number of things can start to go wrong. That’s why manufacturer warranty coverage rarely lasts that long in the first place.

    You don’t have to purchase a plan that covers everything, but it could be a good idea to have at least a basic powertrain plan to cover the most expensive repairs. Here are a few average repair costs, according to RepairPal:

    • Steering gearbox replacement: $854 to $1,086
    • Transmission replacement: $5,109 to $5,286
    • Head gasket replacement: $1,287 to $1,659

    An extended warranty for cars over 100,000 miles can cover a costly repair bill, while you just pay a deductible to the repair facility. Extended warranties and vehicle protection plans cover mechanical breakdowns, not wear and tear, scheduled service, or preventative maintenance. Read the fine print about exclusions thoroughly so you know exactly what’s covered.

    What Are The Best Extended Auto Warranty Companies For Cars Over 100K Miles?

    Frequently Asked Questions

    • Can you get an extended warranty after 100,000 miles?

      Yes, you can get an extended warranty after 100,000 miles, but not many manufacturers offer plans that extend far beyond that. You’ll most likely have to consider third-party options for an extended auto warranty after 100,000 miles.

    • What does a 100,000-mile warranty cover?

      Hyundai, Genesis, Mitsubishi, and Kia all offer 100,000-mile powertrain coverage on new cars. This covers the engine, transmission, and drive axle for 100,000 miles. However, a 100,000-mile extended warranty can cover almost any part of the car depending on the vehicle service contract terms.

    • What manufacturer warranties cover cars past 100,000 miles?

      There are no factory warranties that last beyond 100,000 miles. Kia, Hyundai, and Mitsubishi allow up to 10 years or 100,000 miles for their powertrain warranties, but those don’t last beyond 100,000 miles. Some manufacturers sell extended warranties or dealer-backed service contracts that last up to 120,000, 125,000, or 150,000 miles. Some examples include Volkswagen, Lincoln, Lexus, Audi, Fiat, Volvo, Dodge, Jeep, Honda, Nissan, and Subaru.

    • What happens when a car reaches maximum mileage?

      After 100,000 miles, a range of repair needs can start to come up. You’ll want to watch out for breakdowns involving the drivetrain (engine, transmission, and drive axle). Sometimes you’ll just have to fix worn-out seals and gaskets. Transmissions may have to be replaced in less-reliable vehicles after 100,000 miles. In rare cases, you might have to replace the engine, which can cost up to $5,000 or more.

    • How much does a 100,000-mile extended warranty cost?

      We found that drivers pay between $1,500 and $3,000 for long-term (100,000-mile or more) extended warranty plans on average. What you pay depends on your vehicle and the level of coverage you select.

    • How can I contact Protect My Car customer service?

      Drivers who want to speak with Protect My Car customer service representatives can call 1-844-556-4762. Policyholders who want to file claims due to mechanical issues with their vehicles can contact the claims department at 1-844-256-4762.

    How We Rate Warranty Providers

    Our review process aims to deliver consistent and unbiased assessments of extended auto warranty providers. While there are multiple qualities that make a warranty company successful, our review team focuses on those we believe are the most important for consumers:

    • Cost: Cost can be difficult to compare between providers because so many factors impact vehicle service contract pricing. To determine our cost score, we perform a secret shopper analysis for a variety of vehicles and plans and consider available deductibles.
    • Coverage: Our team of experts looks at the number of extended warranty plans available, as well as term limits, exclusions, and added benefits like roadside assistance. Ratings also take into account the availability of maintenance coverage.
    • Reputation: It’s important that an extended car warranty company is able to meet its claims obligations. Companies with a strong rating from the BBB score well in this category. Established providers with a long history of reliable service also receive positive marks.
    • Customer Experience: We listen to real customer sales calls and comb through reviews on sites like the BBB to learn about customer experiences. Warranty companies with a low volume of complaints score well in this area. We also consider the availability of mobile apps and chat features.
