For years, electric vehicles have been sold with an enticing promise: fewer moving parts, lower maintenance costs, and fewer trips to the service department. That promise is largely true—but it has also created the misconception that EVs are virtually immune to wear and tear. The reality is considerably more nuanced.

With millions of electric vehicles now covering billions of miles worldwide, long-term ownership data is beginning to paint a clearer picture. While EVs eliminate many of the traditional maintenance headaches associated with internal-combustion engines, they introduce a handful of new ones—some of which are directly linked to their greatest strengths.

Heavyweight Champions

The biggest culprit is weight.

Modern battery packs typically add anywhere from 660 to more than 1,400 pounds (300 to 650 kilograms), making even compact electric cars significantly heavier than their gasoline-powered counterparts. That extra mass affects nearly every component connecting the car to the road.

Tires are the first to pay the price.

Combine the additional weight with the instant, neck-snapping torque electric motors deliver from zero rpm, and every enthusiastic launch scrubs away another microscopic layer of rubber. During cornering, the heavier battery pack also places greater loads on the tire sidewalls, accelerating wear even further.

The result? Studies and fleet data suggest EV tires can wear as much as 30 percent faster than those fitted to comparable gasoline vehicles, depending on driving style and vehicle weight.

The suspension doesn’t escape unscathed either. Control arms, bushings, stabilizer links, and other suspension components must constantly cope with higher loads. Simply put, many electric vehicles weigh as much empty as a similarly sized combustion-powered car does with four passengers and luggage onboard.

When Brakes Don’t Brake

Ironically, one of an EV’s greatest technological advantages can create another maintenance concern.

Regenerative braking allows electric motors to recover energy during deceleration, often providing up to 90 percent of the vehicle’s everyday stopping force. That’s excellent for efficiency—and brake-pad longevity—but it also means the conventional friction brakes are used far less frequently.

When brake discs spend extended periods without regular use, particularly in cold and damp climates, corrosion becomes a genuine issue. Winter road salt only accelerates the process, allowing rust to build up on rotors that rarely receive enough friction to clean themselves.

In severe cases, corrosion can reduce braking effectiveness and even lead to inspection failures. It’s one reason some manufacturers have returned to enclosed rear drum brakes on certain EV models. While drum brakes may sound like outdated technology, their enclosed design protects braking components from the elements while regenerative braking handles most everyday deceleration.

Plug-In Hybrids Face a Different Challenge

Plug-in hybrids occupy a unique middle ground—and inherit some unique compromises.

Unlike conventional gasoline cars, their engines often remain dormant for extended periods before suddenly being called into action under significant load. Because the engine starts cold, motor oil takes time to fully circulate, leaving critical components with less-than-ideal lubrication during those first moments of operation.

The situation becomes even more complicated when the hybrid system shuts the engine down before it has reached its normal operating temperature.

Repeated short operating cycles can allow fuel dilution and moisture to accumulate inside the crankcase, increasing the likelihood of deposits forming within the lubrication system and around fuel injectors over time. Owners who primarily make short electric-only trips may never fully warm the engine often enough to evaporate these contaminants.

The Tiny Battery That Still Causes Big Problems

Surprisingly, one of the most common causes of EV breakdowns isn’t the high-voltage battery pack.

It’s the humble 12-volt battery.

Just like in gasoline-powered vehicles, this small battery powers essential electronics and control systems. If it fails, the vehicle may refuse to start—even if the large traction battery is fully charged.

Modern connectivity can make matters worse. Frequently waking the vehicle through smartphone apps or remote features can repeatedly activate onboard systems, creating small but cumulative energy draws that gradually discharge the 12-volt battery while the car sits parked.

Still the Cheaper Car to Maintain

None of these issues erase the biggest advantage electric vehicles still hold over combustion-powered cars: lower routine maintenance costs.

Without engine oil changes, spark plugs, timing belts, exhaust systems, or many of the other consumable components found in gasoline engines, EV servicing remains significantly less expensive over the long haul.

On average, inspection and maintenance costs are roughly one-third lower than those of comparable internal-combustion vehicles. Some manufacturers show even larger savings, with maintenance costs reported to be as much as 58 percent lower for BMW EVs, 45 percent lower for Mercedes-Benz models, and around 44 percent lower for Volkswagen’s electric lineup.

A Few Simple Habits Go a Long Way

Owning an EV doesn’t require special mechanical knowledge, but a few preventative habits can make a noticeable difference.

Checking tire wear regularly can catch uneven wear before it becomes expensive. Occasionally using the friction brakes—particularly during higher-speed driving where safe and appropriate—helps keep brake rotors clean and free from corrosion. Plug-in hybrid owners should also ensure the gasoline engine periodically reaches full operating temperature during longer drives to minimize moisture buildup and fuel dilution.

Electric vehicles may not be maintenance-free, but they remain simpler and generally cheaper to own than traditional combustion cars. The catch is that while they’ve eliminated many of yesterday’s service headaches, they’ve quietly created a few entirely new ones. As EV technology matures, understanding those trade-offs will become just as important as appreciating their undeniable advantages.
