EV Maintenance Myths: What GMC Electric Owners Should Really Know

EV Maintenance Myths: What GMC Electric Owners Should Really Know

Switching to an electric vehicle (EV) comes with plenty of benefits—lower fuel costs, smoother performance, and reduced emissions. But many shoppers still wonder: what kind of maintenance does a GMC EV need? Do EVs require special care? Are repairs more expensive?

At Blasius GMC in Waterbury, CT, we’re here to debunk the myths and give you a realistic look at what maintaining your GMC EV is actually like—whether you’re driving the Hummer EV, Sierra EV, or another electric GMC model.

Myth #1: EVs Don’t Need Any Maintenance

While it’s true that EVs have fewer moving parts than traditional gas-powered vehicles, that doesn’t mean they’re completely maintenance-free. Instead, you’ll see a shift in the type of maintenance required.

EVs don’t need oil changes, spark plug replacements, or emissions tests. However, important systems still need regular attention—including brakes, tires, suspension, coolant (for battery thermal management), and software updates.

What Does GMC EV Maintenance Include?

Here are the top items to keep an eye on as a GMC EV owner:

• Brake Service: Thanks to regenerative braking, your pads last longer—but inspections are still essential.
• Tire Rotations: Electric vehicles are heavier and have instant torque, which can wear tires unevenly without regular rotations.
• Coolant Checks: The battery cooling system uses coolant to regulate temperature. It needs periodic inspection and replacement.
• Cabin Air Filters: Just like any vehicle, this should be changed every 12,000–15,000 miles for clean air and HVAC efficiency.
• Software Updates: Your GMC EV can receive performance and feature upgrades over the air—no service visit required.

Battery Life and Warranty

The battery is the heart of your EV—and it’s built to last. GMC backs its EV batteries with an 8-year/100,000-mile limited warranty, giving you confidence in long-term performance. By avoiding extreme heat, not letting your battery drop to 0%, and using Level 2 charging when possible, you can extend its life even further.

Are EVs More Expensive to Service?

In most cases, no. According to multiple industry studies, EVs generally cost 30–50% less to maintain over time compared to traditional combustion-engine vehicles. Fewer fluids, no exhaust system, and reduced wear on brakes all contribute to lower maintenance bills.
