    We Work With Your Extended Warranty

    Bring us the vehicle and your contract. We handle the diagnosis, the documentation, and the claim submission.

    You bought the coverage. Use it here. MST Motorsports accepts third-party extended warranty and vehicle service contract work on cars, trucks, and SUVs. We diagnose the vehicle, document what we find, and submit the claim to your warranty provider for approval — then get you back on the road.

    How It Works

    1

    Bring It In

    Come by with your vehicle and your warranty contract information. The contract number and your provider's phone number are the most useful things to have with you.

    2

    We Diagnose and Document

    A technician diagnoses the vehicle and documents everything with a digital inspection — photos and part numbers sent straight to your phone. You see exactly what we see.

    3

    We Submit the Claim

    That documentation goes to your warranty provider with the claim. Thorough records are what move a claim along, and thorough records are how we work on every ticket.

    4

    We Do the Repair

    Once it's authorized, our technicians perform the repair in-house and get you back on the road.

    Why Bring Warranty Work to MST

    Documentation That Holds Up

    Every service at MST includes a digital vehicle inspection with photos and part numbers. That is exactly the kind of record a warranty administrator asks for, and it is standard on every ticket we write.

    Your Right to Choose

    The Magnuson-Moss Warranty Act protects your right to have maintenance and repair performed at an independent shop. Many vehicle service contracts also let you pick a licensed repair facility — one clause in the contract usually decides it, so bring your contract by and a service advisor will read through it with you.

    One Shop, Whole Job

    Engine, transmission, drivetrain, electrical, climate, cooling, steering, suspension, brakes, and fuel systems are all handled in-house by our technicians.

    The Right Equipment

    Scan tool and scope coverage across gas, diesel, and hybrid platforms, a Hunter Hawkeye Elite alignment system, and a Hunter Road Force balancer. See our equipment page.
