Introduction

Many car enthusiasts explore the world of aftermarket modifications to enhance their vehicle's performance and aesthetics. However, it is crucial to understand that certain modifications can void your factory warranty. This article provides an in-depth look at the most common modifications that can cause this issue.

Common Aftermarket Modifications and Their Implications

Modifications that typically void factory warranties can range from minor to significant changes, but all can have a negative impact. Below are some of the most common modifications that can lead to such outcomes:

1. Performance Modifications

When making vehicle modifications for the purpose of improved performance, such as 'racing' or 'souping up' the car, you need to be aware that these actions can void your warranty. This includes specific modifications that affect the car's performance:

Exhaust Mods: Upgrading your exhaust system may not be covered by the warranty. These changes are often scrutinized when the warranty is in effect. Chip Mods: Changing the engine management chip to a more powerful or performance-oriented version can result in a voided warranty. The alteration of the factory's computer settings can cause compatibility issues.

True Story:

A 2015 Mitsubishi Lancer Evolution - Sports Sedan, sold as a modified hotrod, was brought back to the dealership with a blown engine. Upon investigation, it was discovered that the car had been raced and had caused the motor to fail. The warranty claim for the motor was denied, and this decision was upheld in court. This incident highlights the importance of knowing how your car modifications can affect its warranty coverage.

2. Tire and Suspension Modifications

Another common area where modifications can void your warranty is in the suspension and tire system:

Incorrect Spark Plugs and Cold Air Intakes: Replacing these components with higher-performance versions can alter the vehicle's normal operating conditions, potentially causing issues that would not arise with factory parts. Tire Modifications: Installing non-factory specified tire dimensions can impact the car's performance and safety, leading to warranty voiding. Suspension Changes: Upgrading your suspension to higher performance components can also lead to issues, especially if the changes are not within the factory specifications.

3. Engine Modifications

The most significant modifications that can void your factory warranty are those affecting the engine:

Electronic Control Unit (ECU) Remapping: Modifying the engine control unit to improve performance or economy can be detected during warranty claims and can void the warranty. Even if the modification does not directly cause the failure, any malfunction can be attributed to it. Aftermarket Wheels and Parts: Installing aftermarket parts can affect the car's balance and overall performance, leading to issues that would not occur with factory components. Headlight Conversion: Changing the headlight system to something other than what was originally installed can cause compatibility issues and void the warranty.

Best Practices:

Bob's Advice: If you modify your car, it's best to ensure these changes are done in a way that maintains the car's original standards. Otherwise, warranties may be voided. Dealers may give you a break on minor changes like exhaust systems and air intakes, but they may also try to scam you in other ways. It's important to read the terms of your purchase contract and understand the conditions for warranty coverage.

Conclusion

Vehicle modifications can be exciting, but they come with potential risks to your warranty coverage. Understanding the specific modifications that could void your warranty and carefully considering their impact is crucial to protect your investment. Always read and follow the terms and conditions of your warranty agreement to avoid any surprises.
