Car brands do not provide good fat tires as wide, and big tires are expensive and drop the mileage by a significant margin. Commonly, many owners replace the original wheels with these aftermarket tires as they offer a firm grip and deliver a powerful stance. But these modifications are dangerous to the warranty, as the fat and big tires put extra stress on the car’s suspension and other mechanical parts.

Audio setup

The default audio system in many cars is dull and with moderate decibels. The hi-fi enthusiasts, however, modify the OEM sound system. This modification results in the default electrical system bearing additional strain with the newly installed powerful and resource-consuming devices.

The audio systems are generally heavy and may also weaken the suspension due to their extra weight. The aftermarket audio setup compels the car brands to void the car warranty.

Modifications in the electrical system

A wide range of options for electrical modifications is available such as horns, lights, etc. Since these accessories need additional power sources, resulting in tampering with the stock wiring harness of the car.

An extra strain comes on the battery and alternator, damaging or weakening them. That’s why a brand won’t agree to provide a warranty in case of electrical modifications undergone in a car.

Remap the engine

A few of us want the cars to be of supersonic speed. Though practically impossible, they try every other method to enhance the speed. The straightforward way to do it is to remap the engine.

Moreover, other upgrades, such as aftermarket air filters, bigger intercooler, etc., can suffice to void the car warranty.


Exhaust is a vital part of the car and plays a prominent role in the combustion cycle. Several buyers procure a free-flow exhaust set up in their vehicles for better performance.

Monitor your service schedule

You may have a chance of voiding your warranty if you don’t keep a check on the service schedule. Not all dealers will remind you of your service requirements, but a few will remind you at regular intervals to offer better customer service.

In both cases, you need to keep alert and get your car serviced as per the schedule.

Many new cars already have an indication system of getting oil or coolant content low or something else helping you to get it serviced in time.

But if your vehicle doesn’t have such a mechanism, you need to set a calendar and keep a log of all details, such as kilometers traveled, days passed from last servicing, tires’ life, etc. You can document the timely services and keep them as a record to claim a warranty whenever required.

Read thoroughly and understand the warranty!

It’s crucial to read and understand the warranty before you buy your vehicle. You may compare different warranties from different manufacturers and try to understand the warranty better to avert any unpleasant situation later.

Ignore denials and push through

There may be a humanistic angle to every warranty, and not everyone will be strict and harsh on the terms. You may find any service manager who will help you out of the way. On the flip side, there may be one who won’t compromise a bit. 

You can always appeal by escalating the issue to upper officials, and lastly, you can seek help from the FTC and/or State Attorney General, Local Consumer Protection Office.
