The average age of cars on the road is 11.8 years old, and that number increases by about 4 percent every 5 years. Because of the increasing age of vehicles, it’s important for drivers to consider the best extended warranty for cars over 100k miles.

In this article, we’ll look at the factors to consider when getting an extended warranty for cars over 100k miles, how to get the best coverage for your high-mileage vehicle, and how CARCHEX can help you avoid costly repairs.

Overview of Extended Warranty Plans

An extended auto warranty works a bit like an insurance policy for your car. Many manufacturer’s warranty plans are limited to 3 years/36,000 miles of coverage, so older vehicles often lack protection entirely. Motorists are potentially risking hundreds or thousands of dollars by driving around without extended warranty coverage.

If you drive a reliable vehicle and are fine going without peace of mind on the road, it might be fine to opt out of an extended car warranty plan. For most owners of cars with over 100k miles, though, purchasing an extended warranty from CARCHEX could reap significant savings and reduce hassle in the event of a mechanical breakdown.

The further your car moves far past its original warranty period, the more likely it’s worth looking at the best extended warranty for cars over 100k miles. Here at CARCHEX, we offer plenty of Extended Vehicle Protection Plans that can keep drivers safe and financially secure when on the road.

Is an Extended Warranty for Cars Over 100k Miles Worth It?

If you’re considering the purchase of an extended warranty for older cars, one of your first considerations should be the price. Extended car warranty costs greatly vary based on your vehicle’s mileage and age, as well as on the level of coverage you select.

You’ll find that not every company offers an extended warranty for cars over 100k miles, so first and foremost look for eligible coverage options. Providers such as CARCHEX offer multiple levels of coverage, different deductible amounts, and various monthly premiums.

To get an idea of your extended auto warranty cost, speak to a CARCHEX representative at 866-261-3547 for a free and instant quote. Then, add up the annual price of your warranty and compare that to the repairs that your high-mileage vehicle is likely to need.

Benefits of an Extended Warranty

Along with price comparisons, it’s smart to consider the added perks the come with the purchase of a CARCHEX Extended Vehicle Protection Plan. You’ll likely find some unexpected benefits that come standard when you have an extended warranty. Below are a few of the potential perks:

  • Longer coverage on parts and services than your original warranty
  • Considerable money saved on repairs for old and high-mileage vehicles
  • Transferable coverage that adds to your car’s resale value
  • Standard services such as trip interruption benefits, rental car reimbursement, and 24/7 roadside assistance
  • No need to be caught off guard by surprise repairs
  • Extended warranties may be the only coverage option for high-mileage cars

The best extended warranty for cars over 100k miles should keep you driving longer and safe from potential breakdowns, repairs, and maintenance issues. At CARCHEX, we work to provide quality protection that can keep even the highest-mileage vehicles functional on the highway.

Common Problems for Cars Over 100k Miles

If you’ve got an older car, be sure to keep maintenance records and carefully follow the service guidelines found in your owner’s manual. However, topping off the oil and buying a new timing belt will only get you so far as a car’s odometer ticks toward the 100,000-mile mark.

Though some car repairs are relatively affordable, costs tend to add up quickly for owners of older vehicles. Below are some common issues that would likely be covered by the best extended warranty for cars over 100k miles:


Repairs for Cars Over 100k Miles

Average Repair Cost

Engine cylinder head replacement


Faulty transmission


Fuel filter replacement


Spark plug replacement


Faulty brake rotors


It’s rarely cheap to maintain an older vehicle, and costs often increase as the years and miles go by. That’s why it’s often a smart move for motorists to pick up an extended warranty from CARCHEX or one of the other reputable extended car warranty companies on the market.

Average Costs for Common Car Repairs

Below are some simple car repairs that drivers regularly run into with high-mileage vehicles. Though most of them run only a couple hundred dollars, repair bills quickly increase as cars begin to show their age.

While you hopefully won’t end up with engine or transmission problems, they become far more common in cars with over 100k miles. Even the smaller repair costs add up over time, though, so it’s smart to be fully protected from potential damages as the years roll by.

What Does an Extended Warranty Cover?

Whether you’re looking for an extended warranty for vehicles over 100k miles or a protection plan for your new car, the following components can usually be covered by CARCHEX:


  • Air conditioning
  • Corrosion
  • Braking system
  • Electrical system
  • Alternators
  • Steering
  • Engine replacements
  • Suspension
  • Emission control
  • Radiators
  • Fuel systems
  • High tech
  • Bedliner damage
  • Transmissions
  • Hybrid components

Additionally, the best extended warranty for cars over 100k miles should offer 24/7 roadside assistance, towing services, rental car reimbursement, gas delivery services, and trip interruption benefits. At CARCHEX, we offer a wide array of added services for drivers to enjoy in times of need.

Be aware that extended warranty plans don’t cover everything. Vehicle service contracts generally exclude wear-and-tear parts like wiper blades and brake pads, and you’ll still have to pay for regular maintenance needs such as tire rotations and oil changes.

Extended Warranty vs. Mechanical Breakdown Insurance

Extended warranties and mechanical breakdown insurance are both legitimate choices when it comes to protecting your car. Either of these warranty options will cover unexpected mechanical issues, and both require a monthly payment.

However, there are some important differences to note:

  • Extended warranties often offer benefits that are left out of mechanical breakdown insurance
  • Mechanical breakdown insurance is from companies with a property and casualty license, while extended warranty providers specialize in vehicle protection plans
  • You may find a more flexible and long-lasting plan with an extended warranty

It’s important to maintain some sort of repair coverage to protect against future repair costs. An extended warranty is likely the better option for those looking for a comprehensive coverage plan.

Tips for the Savvy Shopper

If you’re ready for the best extended warranty for cars over 100k miles, don’t sign anything just yet. Below are a few tips to help you find the best price for an Extended Vehicle Protection Plan:

  • Read the Fine Print
    • If you’ve got over 100k miles on your car, make sure to find out exactly what’s covered in the contract. You’ll also want to consult the list of exclusions found in your sample contract.
  • If You Buy, Go Big
    • An older car may be a great fit for a basic powertrain warranty, but you’ll receive far greater coverage for very little more money with an exclusionary plan. The comprehensive offerings that come close to a dealership’s initial bumper-to-bumper warranty offer you the best deal for what you’re paying.
  • If You Buy Used, Know the Rules
    • Extended warranties cover your total mileage on a car—not the amount you’ve put on it yourself.
  • Do Some Make and Model Research
    • Anticipate what could go wrong with your car and when the issues are likely to surface. There are a couple problems that all cars with 100k miles tend to face, but each model also has particular problem areas. Find out which auto repairs you might need in the near future and how much they’re likely to set you back.
  • Take Stock of Your Car’s Repair History
    • Knowing what’s gone wrong in the past and how frequently issues popped up can help you determine your extended coverage limits, especially if you’re looking to purchase a used car warranty. If possible, get a detailed record of previous car problems and the dates of service.
  • Consider Your Goals with the Car
    • If you’re planning to fix up your car for high-performance driving, know that the average warranty plan may be voided altogether.
    • If you might swap out your car in a few years, consider purchasing an extended warranty to up its resale value. Before you buy, make sure that the warranty is transferable.
    • Traveling a lot? Trip interruption coverage and rental car reimbursement may make an extended warranty worth it if you’re venturing far from home in an older car.

Maintenance to Perform on Your Older Car

If you’re looking for the best extended warranty for cars over 100k miles, there’s a good chance you’re planning to keep your vehicle for as long as possible. If so, here are a few maintenance procedures and repairs to consider making:

  • Fresh fluids: Engine coolant must be changed to avoid water pump, radiator, and heater core replacements. Make sure you know exactly which oil you need and when to change it, as otherwise you may end up hurting an older car.
  • New spark plugs: This can get somewhat pricey, but most cars only need spark plug replacements once every 30,000 to 100,000 miles.
  • Rotate the tires: Every 6,000 miles is a good rule of thumb to make sure your tires are wearing evenly in order to avoid expensive blowouts on the road.
  • Battery checkup: Look for signs of corrosion and loose connections. Aim to test and potentially replace your car’s battery about once every three years.
  • Regularly scheduled maintenance: Belt and hose replacement, engine performance checks, and brake checkups are necessary for your car’s health and longevity.
  • Whatever your manual recommends: Every car is different, so being familiar with its particular quirks can go a long way in preventing minor issues before they become expensive repairs.

There’s a lot that goes into protecting an older car, which is why we recommend picking up an extended warranty. You’ll enjoy covered repairs on everything from your vehicle’s drivetrain and drive axle via powertrain coverage down to the specifics in one of CARCHEX’s exclusionary choices.
