## Does Tuning Your Car Void the Warranty?

Altering your vehicle’s components can affect its warranty coverage.

### Magnuson-Moss Warranty Act

The federal Magnuson-Moss Warranty Act protects consumers from unfair warranty practices. This law states that manufacturers cannot void a warranty unless they can prove that the alteration caused the failure of the part or system in question.

### Manufacturer’s Warranty Language

However, manufacturers can include specific language in their warranties that limit coverage for modified vehicles. These clauses often state that:

– Any alteration to the vehicle’s engine, transmission, or other major components will void the warranty.
– Any installation of aftermarket parts or accessories will also void the warranty.

### Modified Parts and the Warranty

The type of modification and the specific warranty language determine whether tuning will void your warranty:

Powertrain Modifications: Modifications that directly affect the engine, transmission, or drivetrain typically void the powertrain warranty. This includes:

– Performance chips, engine management systems, and turbochargers.
– Exhaust systems, intake systems, and fuel system upgrades.

Suspension and Brake Modifications: Modifications that alter the suspension or brake systems may void certain warranties. These include:

– Lowering springs, coilovers, and upgraded sway bars.
– Performance brake pads and rotors, and aftermarket brake lines.

Cosmetic and Convenience Modifications: Modifications that do not affect the performance or operation of the vehicle typically do not void the warranty. This includes:

– Wheels, tires, and body kits.
– Stereo systems, navigation units, and remote start systems.
