ABOUT ELECTRIC VEHICLE (EV) MAINTENANCE SCHEDULE

Electric vehicles (EVs) have fewer moving parts than gas-powered vehicles, resulting in the need for less scheduled maintenance. Even so, EVs still require regular maintenance and attention to EV-specific components to help ensure driving safety and optimal performance. Learn about essential maintenance and service schedules for your Cadillac electric vehicle.

Battery Care and Maintenance

The battery is the primary component of your electric vehicle. Taking proper care of it and establishing proactive habits can help extend the life of your EV’s battery.
 

  • Daily Charging: For daily use, maintain a charge level between 20% and 80%. Avoid charging to 100% or depleting to 0% regularly, as this stresses battery cells.

  • Fast Charging: Limit the use of DC Fast Charging to necessary trips. Frequent high-speed charging generates heat that may degrade battery chemistry over time. Use Level 2 charging for routine needs.

  • Temperature Management: Extreme temperatures impact battery efficiency. Whenever possible, park in shaded areas during hot weather and in garages during freezing conditions.

  • Storage: If storing the vehicle for an extended period, consult your Owner’s Manual for the specific recommended charge level. Do not store the vehicle fully charged or fully depleted.

Vehicle Software and Electronics

Software manages your vehicle’s battery efficiency, charging speed and overall performance.

  • Software Updates: Install Over-the-Air (OTA) software updates as soon as they become available. These updates frequently include optimizations for the Battery Management System (BMS).

  • Diagnostics: If you see any warning lights or system alerts on your dashboard, schedule a diagnostic check immediately.

Tire Maintenance

EVs are heavier than gas vehicles and deliver instant torque, which may result in accelerated tire wear. Therefore, checking on and maintaining the health of your tires is important.

  • Rotations: Rotate tires every 7,500 miles or as recommended in your Owner’s Manual. This is critical for even tread wear.

  • Inspections: Check tire pressure regularly. Improper inflation may reduce range and efficiency.

  • Replacement: When replacing tires, be sure to select tires specifically rated for the weight and load of an electric vehicle to help maintain range and safety standards.

Brake System Checks

All Cadillac EVs are equipped with traditional friction brakes that require regular inspection and maintenance. If your EV is also equipped with regenerative braking, this feature can help slow the wear encountered on brake pads and rotors. When maintaining your EV’s brake system, it’s important to consider the following:

  • Fluid Flushes: Brake fluid absorbs moisture over time. Flush and replace brake fluid every 2–3 years, or according to your manufacturer’s schedule, to help prevent corrosion in the brake lines.

  • Rotor Cleaning: Because friction brakes may be used less frequently with regenerative braking, rust can accumulate on rotors. An annual inspection and cleaning of the calipers and rotors can help ensure your EV’s mechanical brakes function correctly when needed.

Fluid and Filter Schedule

Though EVs do not require oil changes, other fluids and filters must be monitored.

  • Cabin Air Filter: Replace the cabin air filter annually or every 12,000 miles to help ensure proper air quality inside the vehicle.

  • Coolant Systems: EVs use coolant to regulate the temperature of the battery and electric motor. Check coolant levels during regular service intervals and flush the system according to the specific timeline in your Owner’s Manual.

  • Windshield Washer Fluid: Check and refill regularly.

Maintain EV Safety with Cadillac Certified Service

High-voltage EV components can pose serious risks if not handled properly and should only be serviced by qualified professionals. If you have questions about the maintenance schedule of your EV or are ready to schedule a service appointment, the best and safest option is to contact your local Cadillac Certified Service provider.

Consult your Owner’s Manual to find more information about the maintenance recommendations specific to your Cadillac EV model.

Q&As

CAN I USE TESLA EQUIPMENT TO CHARGE MY GM VEHICLE?

You can now charge your properly equipped GM EV on a wide range of charging stations, including compatible Tesla Supercharger† locations, with the help of the GM NACS DC adapter and on NACS home chargers with the GM NACS Level 2 adapter. Some NACS stations may not be compatible with GM EVs or adapters. Consult your vehicle mobile app for real-time availability and requirements. For more information on using NACS charging stations, see How to Charge Your EV at a Public Charging Station.

WHAT ARE THE BENEFITS OF CHARGING ONLY TO 80%?

Charging your battery to 80% for daily use helps promote battery health and optimal regenerative braking performance. For longer trips, you can adjust your charge above 80% for extended range. See your Owner’s Manual for more information.
