GMC Vehicle Maintenance and GMC Pro Grade Protection Plan


Nobody knows your vehicle better than the GMC Certified Service expert technicians. As trained professionals, they can help recommend the optimum maintenance schedule for your GMC vehicle. Advanced technologies, such as the engine Oil Life System (OLS), also keep you well informed. The Oil Life System calculates oil deterioration and indicates when an oil change is needed, which may affect the frequency and type of other services required. And now, with GMC Pro Grade Protection, select scheduled maintenance services are covered for the first 2 years or 24,000 miles (whichever comes first).*


Professional Grade maintenance—that’s GMC Pro Grade Protection, which comes standard on all 2014 and newer GMC vehicles. GMC Certified Service experts can help you take full advantage of the benefits found with GMC Pro Grade Protection, such as included scheduled maintenance*, specifically oil changes, a thorough Multi-Point Vehicle Inspection, and a 4-tire rotation (single axle). It also features a Bumper-to-Bumper Warranty, 24-Hour Roadside Assistance, Courtesy Transportation, Powertrain Limited Warranty Coverage, and a 6-month OnStar trial for your GMC.
