Expert Electric Vehicle Service and High-Voltage Care in Bentonville Maintaining a modern electric vehicle requires a shift in how we think about automotive care. While you no longer need to worry about traditional engine components, the high-voltage battery and electric drive unit demand specialized attention from technicians who understand these complex systems. At George Nunnally Chevrolet we have invested in the diagnostic tools and safety equipment necessary to handle everything from routine software updates to intricate electrical repairs. Our team is trained to navigate the specific architecture of Chevrolet EVs, ensuring that your vehicle remains as efficient as the day you drove it home. When local drivers visit our service and parts department, they find a team that prioritizes transparency and technical precision. We understand that transitioning to an electric lifestyle comes with new questions about long-term reliability. Whether you are noticing a change in your charging speed or simply need a professional to look over your high-voltage cables and connectors, we provide the expert oversight required to keep your car on the road. For those who prefer to plan ahead, you can easily book a maintenance visit online to secure a time that fits your busy schedule. Safety remains our primary concern, especially when dealing with the heavy-duty braking systems found on electric models. Because EVs utilize regenerative braking to feed energy back into the battery, the physical brake pads often last longer than those on gas vehicles, but they still require periodic inspection to prevent seizing or uneven wear. We offer specialized brake system evaluations to ensure your stopping power is never compromised. If your vehicle still utilizes an internal combustion engine for hybrid power, we also provide professional oil change services to keep that side of your powertrain healthy. If you need help finding us, our location at 2700 Se Moberly Ln is easy to reach for anyone in the area. For immediate questions, feel free to give us a quick call at (479) 319-2494.

While it is true that you can say goodbye to spark plugs and timing belts, your EV still relies on several critical mechanical systems that require regular upkeep. Tire management is perhaps the most vital area of focus. Because electric cars are typically heavier due to their battery packs and deliver instant torque to the wheels, they can wear through rubber faster than traditional cars. We perform regular rotations and alignments to help you get the maximum life out of your tires, which is essential for maintaining your driving range. Our service center is equipped to handle the full spectrum of Chevrolet electric models, including the 2026 Chevrolet Bolt EV and the 2026 Chevrolet Bolt EUV. We utilize genuine OEM components for every repair, which is a critical distinction when dealing with high-voltage electronics. Using parts designed specifically for your vehicle's VIN ensures that all safety protocols and performance standards remain intact. If you are a DIY enthusiast looking for cabin air filters or wiper blades specifically designed for your model, you can request genuine Chevy parts directly through our website. Beyond the mechanical components, software plays a massive role in how your electric vehicle performs. We use specialized GM diagnostic computers to check for "Over-the-Air" update completions and to calibrate the battery management system. This ensures your range estimates stay accurate and your thermal management system operates at peak efficiency. For those looking to join the electric revolution with a pre-owned model, we often have one-owner vehicles with verified histories that have been through our rigorous multi-point inspection process. This level of scrutiny allows us to catch potential issues before they become expensive repairs, providing peace of mind for every mile of your commute. Understanding EV Thermal Management: Battery Coolant Flush Intervals and Procedures The battery in an electric vehicle is sensitive to temperature extremes, which is why Chevrolet engineers designed a sophisticated liquid cooling system to keep the cells within an ideal operating window. This system is what allows for consistent DC fast-charging speeds and protects the battery's longevity during the humid summers we see in Bentonville. Over time, the coolant can degrade or become contaminated, which reduces its ability to transfer heat effectively. We recommend a comprehensive battery cooling system flush every 150,000 miles or every five years, whichever comes first, to ensure your thermal management remains optimal. During this procedure, our technicians drain the old fluid, pressure-test the lines for leaks, and refill the system with specialized non-conductive coolant. This isn't the same fluid you would find in a traditional radiator; it is specifically formulated for high-voltage environments. Neglecting this service can lead to decreased charging efficiency or, in extreme cases, a reduction in the total power the battery can deliver. For owners of the latest Chevy Bolt models, staying on top of this interval is one of the best ways to protect your investment over the long haul. We also pay close attention to the cooling fans and heat exchangers located at the front of the vehicle. These components can often collect road debris or leaves, which blocks airflow and forces the cooling system to work harder. As part of our multi-point inspection, we clear these areas and verify that the coolant pumps are cycling correctly. This proactive approach to thermal management is a hallmark of our service philosophy, ensuring that your EV can handle everything from stop-and-go traffic to long highway stretches without breaking a sweat. Battery Capacity Protection and Long-Term Warranty Coverage for Chevrolet EVs A primary concern for many first-time electric owners is how the battery will hold up over a decade of use. Chevrolet provides a robust 8-year / 100,000-mile battery and electric component warranty to address this directly. This coverage typically protects you if the battery capacity falls below 70% to 75% of its original rating during the warranty period. At George Nunnally Chevrolet we can perform a "State of Health" test on your battery pack to give you a clear percentage of its current capacity, which is a great tool for tracking performance as your vehicle ages. While we specialize in high-voltage care, we also support the full lineup of Chevrolet's diverse fleet. We know many of our EV owners also keep a heavy-duty truck or a large SUV in the garage for weekend adventures or work. Our technicians are equally skilled at maintaining the 13,300 lbs towing capacity of the new Chevrolet Silverado 1500 or the massive torque of the Silverado 2500HD and Silverado 3500HD models. Whether you drive a Silverado 3500 DRW for maximum payload or a new Chevrolet Corvette for pure performance, we provide the same level of certified expertise. Our service department also handles the specialized needs of family-oriented vehicles. We see many parents choosing the new Chevrolet Blazer EV for its modern tech, while others prefer the traditional power of a new Chevrolet Suburban or the new Chevrolet Tahoe. From the compact Chevrolet Trax and Chevrolet Equinox to the mid-size Chevrolet Traverse and Chevrolet Blazer, every model benefits from our Nunnally Buyer's Advantage Program. This includes three years of complimentary maintenance, covering oil changes and tire rotations for our gas models, ensuring that whether you drive a new Chevrolet Colorado or a track-ready Corvette ZR1, your vehicle is always in top shape. Even for those with a standard Colorado or a Corvette Stingray, our commitment to reliability remains the same across the board. Common Questions About Maintaining Your Electric Vehicle in Northwest Arkansas Q: Does my electric vehicle need an "oil change" for the electric motor? Electric motors do not require engine oil like a gas vehicle, so you will never need a traditional oil change for the drive unit. However, the reduction gear or transmission in an EV does contain a specialized lubricant that may need to be inspected or replaced at very high mileage intervals. Our technicians check these fluid levels during your multi-point inspections to ensure everything remains sealed and lubricated. Q: Why do my tires seem to wear out faster on an EV than on my old gas car? Electric vehicles produce 100% of their torque instantly, which puts more stress on the tire tread during acceleration. Additionally, the heavy battery packs mean the tires are supporting more weight constantly. We recommend tire rotations every 7,500 miles to help distribute this wear evenly and extend the life of your rubber. Q: Can I use a standard 12-volt battery charger if my EV won't start? Most electric vehicles still use a traditional 12-volt lead-acid battery to power the lights, infotainment, and computer systems. If this small battery dies, the car won't "turn on" even if the big high-voltage battery is full. You can often jump-start or charge this 12-volt battery just like a normal car, but you should always consult your owner's manual for the specific terminal locations to avoid damaging the sensitive electronics. Q: Will using DC fast chargers all the time damage my battery? While modern Chevrolet EVs are designed to handle fast charging, frequent use of high-speed chargers can create more heat, which may slightly accelerate battery degradation over many years. For the best long-term health, we recommend using Level 2 home charging for your daily needs and saving the DC fast chargers for road trips or emergencies. Q: Does the regenerative braking system ever need maintenance? The regenerative system itself is largely electronic and requires little physical maintenance, but because it does so much of the work, your mechanical brake rotors can sometimes develop surface rust from disuse. We inspect the calipers and rotors during service to ensure they move freely and haven't become "sticky" due to the lack of frequent friction.
