2018 GMC Acadia - Electric Vehicle Guide
The 2018 GMC Acadia belongs to a GMC Acadia lineup that Know Your Ride tracks across 7 model years, from 2018 to 2026. It is an all-electric vehicle, so it skips the oil changes, spark plugs and exhaust-system service of a combustion Acadia entirely. It is configured as front-wheel drive with an automatic 6-spd. This 2018 car is the earliest model year on record for the GMC Acadia.
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 3 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.
