The GM-recommended EV service schedule differs from a traditional combustion engine plan, with fewer oil changes and more focus on battery, charging, and brake system health. Skipping scheduled EV maintenance shortens battery life and can void your GM warranty coverage. Bring your Buick or GMC EV to Greg Hubler in Marion and we will walk you through exactly what your vehicle needs.
The EV service schedule is built around the systems that actually wear on an electric vehicle. At Greg Hubler Buick GMC, our GM-trained technicians perform every item on the manufacturer-approved checklist.
Core services in the EV maintenance plan include:
The high-voltage battery is checked for state of health, proper thermal management, and any diagnostic trouble codes. The AC charging port and DC fast-charge port are inspected for corrosion and proper seating.
Because regenerative braking reduces how often friction brakes engage, brake fluid can absorb moisture faster than drivers expect. GM recommends a brake fluid inspection and replacement on a schedule tied to time rather than mileage alone.
EV torque delivery is immediate and puts uneven load on tires. Regular rotation extends tire life and helps maintain the range estimate the vehicle was designed to deliver.
A clogged filter reduces HVAC efficiency, which draws more energy from the battery on hot or cold days in Indiana.
The battery thermal management system uses its own coolant loop. Technicians check coolant level, condition, and system pressure.
These follow the same schedule as any vehicle and are checked at every visit.
The GM EV service schedule is primarily time-based and mileage-based, not symptom-based. The best approach is to follow the intervals in your owner’s manual or the reminders on your vehicle’s Driver Information Center.
That said, bring your vehicle in sooner if you notice any of the following:
