A gas engine has hundreds of moving parts, fluids and filters that wear. An electric motor has very few. That difference shows up in the service bill: a Consumer Reports analysis found that battery-electric cars cost roughly half as much to maintain and repair over their life as comparable gas cars. But “less” is not “none”, and a few items actually wear faster on an EV.
What an electric car no longer needs
- Engine oil and oil filter
- Spark plugs and ignition parts
- Engine air filter and fuel filter
- Timing belt or chain, drive belts for engine accessories
- Exhaust system, catalytic converter, emissions repairs
- A conventional multi-speed transmission and its fluid (most EVs use a single-speed reduction gear; some makers still list a fluid check)
What every EV still needs
Tires: they wear faster
Batteries make EVs heavier than similar gas cars, and electric motors deliver full torque instantly. Both are hard on tires, and owners commonly report replacing them sooner. Keep pressure right, rotate on schedule and watch tread depth closely. Our guide on when to replace tires covers how to check.
Brakes: pads last longer, fluid does not
Regenerative braking slows the car with the motor and sends energy back to the battery, so the friction brakes do much less work. Pads and rotors often last far longer than on a gas car. The flip side is that brakes used lightly can corrode, especially where roads are salted, so they still need regular inspection. Brake fluid absorbs moisture over time and typically needs changing every two to five years, the same as on any car.
Coolant for the battery and electronics
Most EVs circulate coolant through the battery pack, motor and power electronics to keep them at the right temperature. Intervals are usually long, sometimes many years, but they exist. The owner’s manual will list them.
The other usual items
- Cabin air filter, usually every year or so
- Wiper blades and washer fluid
- Suspension, steering and wheel alignment checks
- The 12-volt battery, which runs the lights, locks and computers and can still go flat
- Software updates, which on many EVs change charging and battery behavior
The high-voltage battery
The traction battery is not a service item in the usual sense. It slowly loses some capacity over the years, faster with frequent fast charging and extreme heat. Most automakers warrant it for at least 8 years or 100,000 miles. The best thing an owner can do is follow the manufacturer’s charging advice, which for many cars means not leaving it at 100% for long periods.
Hybrids: a gas car with help
A regular hybrid or plug-in hybrid still has a full gas engine, so it keeps almost all of the gas car schedule: oil and filter, spark plugs, air filters, coolant and the rest. A few things are different:
- Brakes last longer thanks to regenerative braking, just as on an EV.
- Oil ages by time. A plug-in hybrid that runs mostly on electricity may barely use its engine, but the oil still needs changing on the time limit in the manual.
- Extra cooling loops for the hybrid battery and inverter, sometimes with a separate coolant and an air filter for the battery fan.
- The starter and alternator are often gone, replaced by the hybrid system, which removes two common failure points.
Keeping the right schedule
Generic maintenance apps often show an oil change reminder to an electric car owner, which is useless. When you add a car to Badger you pick its powertrain: gas, diesel, hybrid, plug-in hybrid or electric. An electric car gets a schedule without oil, spark plugs, fuel and air filters, transmission fluid or timing belt. A hybrid keeps the engine items. Charging sessions are logged in kWh, and our guide on EV charging cost shows how to price them.
Common questions
Do electric cars need any regular service at all?
Yes, just less of it: tire rotation and replacement, brake inspection and fluid, cabin filter, coolant at long intervals, wipers and the 12-volt battery.
Do EV tires really wear faster?
Often, yes. Extra weight and instant torque increase wear. Tires designed for EVs and gentle acceleration help.
Does a plug-in hybrid that rarely uses gas still need oil changes?
Yes, on the time limit in the manual. Oil ages even when the engine runs little, and some plug-ins start the engine periodically to keep it healthy.
