2023 Buick Encore GX - Electric Vehicle Guide
The 2023 Buick Encore GX belongs to a Buick Encore GX lineup that Know Your Ride tracks across 5 model years, from 2022 to 2026. It is an all-electric vehicle, so it skips the oil changes, spark plugs and exhaust-system service of a combustion Encore GX entirely. It is configured as front-wheel drive with an automatic (variable gear ratios). The 2023 sits mid-run, with both earlier (2022) and later (2026) Encore GX model years also documented.
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 13 scheduled maintenance items for this vehicle, the earliest interval falling at 7,500 miles. Documented torque values include lug nut 100 ft-lb.
NHTSA complaints for this vehicle cluster around unknown or other (3), engine (2), power train (2). A representative report reads: "the evaporative emissions purge pump or an ECM calibration fault code P0521"
Estimated annual charging cost runs near $1,450.
