Does a VT Supercharger Void My Warranty?
Does a VT Supercharger Void My Warranty?
Warranty concerns are one of the most common reasons people hesitate before adding a performance modification to their vehicle. It's a legitimate concern — and the answer is more nuanced than a simple yes or no. Here's what you actually need to know.
The Magnuson-Moss Warranty Act (US)
In the United States, the Magnuson-Moss Warranty Act protects consumers from having their entire factory warranty voided simply because they added an aftermarket part. Under this law, a dealer or manufacturer cannot void your warranty unless they can demonstrate that the aftermarket modification directly caused the failure in question.
In plain English: adding a supercharger doesn't automatically void your entire warranty. If your air conditioning compressor fails, the dealer can't blame your supercharger for that. However, if you have an engine-related warranty claim, the dealer may argue that the supercharger contributed to the issue.
What Parts of My Warranty Are Most at Risk?
The areas most likely to be scrutinized after adding a supercharger are powertrain-related: engine, transmission, and drivetrain components. If you have a warranty claim on one of these components, the dealer may investigate whether the modification contributed to the failure.
This is why it's important to:
- Install the kit correctly and follow all instructions
- Use a tune if one is recommended for your platform
- Run quality fuel and maintain the engine properly
- Keep records of your installation
VT Supercharger's Own Warranty
VT Supercharger kits come with their own warranty coverage. If there's a problem with the kit itself — a defective component, a fitment issue — that's covered. Check the product page for specific warranty terms for your kit.
What Should I Do Before Installing?
If you're concerned about your factory warranty, it's worth having a conversation with your dealer before installing. Some dealers are more performance-friendly than others. You can also consult with a legal professional familiar with the Magnuson-Moss Act if you want a thorough understanding of your rights.
The Practical Reality
The vast majority of VT Supercharger customers drive their vehicles daily without warranty issues. The kits are engineered to operate within safe parameters, and when installed correctly, they don't stress the engine beyond its design tolerances. Most customers never have a warranty-related problem.
