2023 Cadillac CT4 - Electric Vehicle Guide
The 2023 Cadillac CT4 belongs to a Cadillac CT4 lineup that Know Your Ride tracks across 3 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 CT4 entirely. It is configured as all-wheel drive with an automatic (s8). The 2023 sits mid-run, with both earlier (2022) and later (2026) CT4 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 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.
