2021 Cadillac XT6 - Electric Vehicle Guide
The 2021 Cadillac XT6 belongs to a Cadillac XT6 lineup that Know Your Ride tracks across 2 model years, from 2020 to 2021.

This 2021 car is the most recent Cadillac XT6 model year on record.
The high-voltage battery is covered for 8 years or 100,000 miles, separate from the bumper-to-bumper warranty. Routine upkeep centers on tire rotation, DOT 4 brake fluid, Dex-Cool battery/cabin coolant, cabin air filters and brake service rather than engine oil. Know Your Ride lists 14 scheduled maintenance items for this vehicle, the earliest interval falling at 7,500 miles. Documented torque values include lug nut 100 ft-lb.
