2021 Chevrolet Silverado 1500 - Electric Vehicle Guide
The 2021 Chevrolet Silverado 1500 belongs to a Chevrolet Silverado 1500 lineup that Know Your Ride tracks across 20 model years, from 2000 to 2026. It is an all-electric vehicle, so it skips the oil changes, spark plugs and exhaust-system service of a combustion Silverado 1500 entirely. It is configured as rear-wheel drive with an automatic 8-spd. The 2021 sits mid-run, with both earlier (2000) and later (2026) Silverado 1500 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 14 scheduled maintenance items for this vehicle, the earliest interval falling at 5,000 miles. Documented torque values include lug nut 120 ft-lb.
