Both of these plans would cover the Outback for between 51,000 and 60,000 miles.

Are Extended Warranties Worth It For Cars Over 100K Miles?

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: $905 to $1,095
  • Transmission replacement: $5,092 to $5,291
  • Head gasket replacement: $1,853 to $2,149

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, but not wear and tear, scheduled service, or preventative maintenance. Read the fine print about exclusions thoroughly so you know exactly what’s covered. Your cost will vary based on a variety of factors, including the provider you choose, as shown below.

What Happens When A Car Reaches Maximum Mileage?

While there is no maximum mileage for all cars, the cost of repairs can become more expensive as cars age. Each car model is unique, however, if the car has been driven hard, the maximum mileage could be as early as 150,000 miles. On the other hand, some well-maintained vehicles can reach 300,000 miles and beyond.

Are 100K Miles A Lot For A Car?

If a car is well-maintained, 100,000 miles is considered the halfway point in its life. You can expect well-maintained vehicles to make it to at least 200,000 miles and potentially more. No manufacturer warranty lasts that long, which is why it can be a good idea to consider an extended warranty for cars over 100K miles.



Car Warranty For Older Cars

One of the biggest factors, besides mileage, that can impact your vehicle’s eligibility for an extended car warranty is age. For example, if you have a car that is a decade old and has 200,000 miles, most extended car warranty providers would not cover it.

In this instance, you would be forced to pay for unexpected repairs out of pocket since your factory warranty might be expired. The good news, however, for older car owners is that they can get extended car warranty coverage from the providers above, even when their vehicles have over 100k miles.

Should I Get An Extended Warranty For Older Cars?

While a vehicle’s age doesn’t necessarily impact the number of problems it has, older cars do tend to break down more frequently. Those driving older cars should consider getting extended warranties for unexpected cases to avoid paying bills from their own pockets.
