2020 Cadillac XT6 - Electric Vehicle Guide
The 2020 Cadillac XT6 belongs to a Cadillac XT6 lineup that Know Your Ride tracks across 2 model years, from 2020 to 2021. It is an all-electric vehicle, so it skips the oil changes, spark plugs and exhaust-system service of a combustion XT6 entirely. It is configured as front-wheel drive with an automatic (s9). This 2020 car is the earliest model year on record for the Cadillac XT6.
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.
