Performance tuning
Aftermarket engine software, ECU remapping, modified intake or exhaust systems, and other changes that alter factory performance.

Repair warranty
Whichever comes first. The repair order or invoice provided at the time of service contains the terms that apply to your repair.
Vehicle alterations
A non-factory alteration does not automatically mean every repair is excluded. Warranty coverage may not apply when an alteration caused, contributed to, or interfered with the diagnosed failure or the repair.
Modified components can place additional stress on related systems and can make it difficult to determine whether a covered repair failed or the alteration caused the concern. We evaluate each request based on the repair performed, the affected system, and the vehicle’s condition.
Aftermarket engine software, ECU remapping, modified intake or exhaust systems, and other changes that alter factory performance.
Lift kits, lowering springs, custom coilovers, oversized tires, or wheel setups that change the vehicle’s factory geometry or operating loads.
Aftermarket remote starters, alarms, audio equipment, lighting, or non-factory wiring that may affect the repaired system.
Frame changes, custom body work, or other substantial modifications that affect the vehicle’s original design or the repair performed.
Before requesting coverage
Please have your repair order or invoice, current mileage, a description of the concern, and details about any modifications related to the affected system.
No. We review whether the modification is connected to the failure or interferes with the repair. Unrelated alterations are considered separately.
The vehicle inspection and the warranty terms shown on the applicable repair order or invoice determine coverage. Additional exclusions or limitations may apply to a specific repair.
