GMC offers a bumper-to-bumper Platinum Extended Warranty for owners who want to purchase longer coverage.
What does the GMC Extended Warranty cover?
The GMC Platinum Warranty covers the engine, turbocharger, transfer case, steering, adaptive cruise control, power windows, heated seats, electronics, fuel pump, water pump, radiator, and everything else except items explicitly listed as exclusions on the contract.
Where can I buy the GMC Platinum Warranty? Insider Tip:
Purchase the extended warranty from the Finance Department at the dealership you intend to return to for repairs.
Customer satisfaction ratings are higher for repeat clients because dealer bonuses depend on your participation in surveys provided by GMC.
When you return for service verify that your current email is on file, and remind the Service Advisor that you plan to give good marks on the GMC survey, and you will be surprised by the improvement in service.
