Because the T8 powertrain utilizes both a high-capacity electric motor and a turbocharged gasoline engine, adhering to the 10,000-mile service interval ensures both systems operate seamlessly together. During this routine visit, technicians replace the synthetic engine oil and oil filter. This keeps the internal combustion components properly lubricated and prevents excessive heat buildup during intense Savannah summers. Additionally, certified technicians inspect the high-voltage battery cooling system to ensure optimal electric range and performance.

This interval also includes a replacement of your cabin air filter. The high humidity levels and heavy spring pollen along the Georgia coast cause air filters to work harder, so regular replacements ensure you breathe clean, purified air inside the cabin.
