7 Exclusions of Your Warranty Coverage

7 Exclusions of Your Warranty Coverage

Similar to car and health insurance, a comprehensive warranty for your vehicle can provide great peace of mind. However, it’s always preferable to never need to use it.

While the depth and duration of coverage can vary among automakers and vehicles, there are typically certain items that are not covered under a comprehensive warranty. Here are seven important points to bear in mind:


It’s essential to differentiate between a powertrain warranty and a comprehensive warranty. The powertrain warranty generally encompasses the engine, transmission, drivetrain, and other propulsion-related components.

These warranties often have the longest coverage duration, with many extending beyond 5 years or 60,000 miles. Consequently, the engine and other powertrain elements are typically excluded from the comprehensive warranty and fall under the jurisdiction of the powertrain warranty.


Most comprehensive warranties provide specific details about “wear and tear items.” However, as a general rule, it’s best to consider components that are likely to require replacement during the lifespan of the vehicle.

Examples include brake pads, tires, and wiper blades. Such items are typically not covered by the comprehensive warranty. Even bulbs and fuses are often excluded.


Many warranties traditionally exclude coverage for vehicle upholstery, trim pieces, and even glass and other cabin surfaces. This is because most warranties only cover issues resulting from manufacturing defects.

For instance, if your seat belt malfunctions, it will likely be covered. However, if there’s a hole in your leather upholstery with an ink stain, it may be assumed that the cause was a pen and not a production defect.

If you notice any peeling, cracking, or signs of design flaws in your interior finishes, it is advisable to visit a dealership promptly to document the defect.


Vehicle batteries typically have their own warranty coverage, which is typically shorter than the standard comprehensive warranty duration. As of 2023, the norm for battery coverage is around 2 years or 24,000 miles.


Comprehensive warranties usually include coverage for rust corrosion that occurs through no fault of the driver. However, most automakers will not cover rust resulting from sand, salt, tree sap, or hail.

Other exclusions include rust caused by scratches from stones or gravel. Terms and conditions for rust coverage often differ from those of the standard warranty and can vary significantly among manufacturers. Some extended warranties may offer additional add-ons for rust protection.


While the ability to call for roadside assistance is typically provided for a certain period following a vehicle purchase, it is usually only covered for a limited duration.

After this period, you may be required to pay a monthly fee to continue enjoying the service. If your subscription expires or you prefer not to pay the fees, alternative organizations such as AAA, OnStar, or even American Express may offer subscription packages at lower costs compared to those offered by automakers.


Modern cars are equipped with advanced technology, including stereo systems, DVD players, and touchscreens. However, similar to roadside assistance, coverage for entertainment components often has different duration limits than the rest of the comprehensive warranty.

Most manufacturers do provide coverage for factory-installed audio systems, but only for a limited time. In the event of specialized repairs, it is best to consult your certified dealer, who can make the necessary referrals.

While these exceptions may seem disappointing, it’s crucial to consider the positive aspects. Automakers strive to compete based on the reliability and longevity of their vehicles. By diligently maintaining your vehicle and keeping accurate records, you can enhance your warranty experience if and when an issue arises.
