Electric Cars Are More Reliable And Require Less Maintenance

As electric vehicles have become more popular, some clear differences between them and traditional cars have become obvious. One of the best things that have become apparent with EVs is that they have a lot lower maintenance costs and requirements. Sure there are some things that need special attention, such as battery packs, that regular cars don’t have, but there are many routine maintenance items that an EV doesn’t use at all.

Here’s a quick list of some of the many items that you won’t have to maintain or replace in an EV.

Oil change mess


An internal combustion engine requires a few different fluids to operate. Engine oil is pretty much the most important fluid. Most automotive engines require the engine oil to be changed anywhere from every 3,000 – 6,000 miles. Not only is this inconvenient, the price really starts to add up. Many luxury brands and sports cars require that the oil that is used for them be fully synthetic. Full synthetic oil is much more expensive than traditional oil. If you consider that you’ll be buying oil for your new car roughly every 5 to 6 months, this gets pricey.

An Electric motor uses no oil. If your car is powered by an electric motor, you will not need to buy oil. You won’t have to pay to have your oil changed and you won’t need to buy oil filters.

Transmission fluid is another type of oil that you don’t need to buy for an Electric. Traditional automatic transmissions use a type of hydraulic fluid that is called automatic transmission fluid, or ATF. Not only does this fluid require periodic checking and replacing, it also goes through a transmission fluid filter in the transmission that needs periodic replacement. Replacing the transmission filter usually involves removing the oil pan from the bottom of the transmission. To reinstall the pan you also need a new trans pan gasket! You can see how all of this adds up. Not to mention the cost of the labor if you’re not mechanically inclined.

Having a manual transmission only partially helps you to save these expenses. A manual transmission will still usually have a hydraulic clutch. This clutch uses hydraulic cylinders with hydraulic fluid and a hydraulic fluid reservoir. This system usually uses DOT 3 or DOT 4 fluid. A manual transmission also has gear oil inside of it. This oil is good for a long time, but it does need changed around 100,000 miles. Most electric vehicles require none of these fluids.

Gas engines need a lot of service.


All modern automotive engines are liquid cooled. The coolant used in these engines has many drawbacks. It can freeze and destroy your engine. It’s also highly toxic to people and animals. If you have an electric vehicle you can avoid worrying about the following cooling system issues:

  • Blown, clogged, or leaking radiator
  • Worn out radiator cap
  • Water pump replacement
  • Radiator hoses worn or leaking
  • Thermostat sticking or causing overheating
  • Heater core clogged or leaking
  • Radiator fan broken or not working
  • Engine overheating

There are tons of little odds and ends that a modern car or truck engine needs to run properly. An electric motor needs very few parts in comparison.


Because an internal combustion engine contains fluids and gasses, it needs many gaskets. All of these gaskets have a life expectancy. Some will last longer than others, but at some point, they will all need changed. There are gaskets to seal oil, gaskets to seal coolant, gaskets to seal exhaust gasses, and many others.

Emissions equipment

Due to the bad effects on the environment caused by automotive exhaust, current engines have a lot of emissions control equipment. All of this equipment needs to be functional for your vehicle to be legal. Much of it needs periodic replacement. PCV valves and vacuum lines will always need replaced at some point. Breathers, O2 sensors, catalytic converters, all of these emissions components are going to wear out and need replaced eventually. A vehicle powered by an electric motor has none of these and therefore has none of the associated replacement costs.

Gasoline handling

An EV uses no gasoline. Because of that, it doesn’t have a gas tank to rust or leak. It also doesn’t have a gas cap that will need periodic replacement due to evaporative discharge codes. There is no fuel filter that will need to be changed, no fuel pump to go bad, no fuel injector cleaning that needs to be done, and no leaks of toxic gasoline into the ground.


Many subsystems on an internal combustion engine are run by a belt attached to the crankshaft of the engine. The water pump, the air conditioning, the power steering, the charging system, all of these and more are run by belts. In newer cars there has been a push to reduce the number of belts down to one long belt called a serpentine belt. In this type of setup, if that one belt breaks you are completely stuck. Not only does an Electric car not have this issue, it also doesn’t require you to inspect and replace old and worn belts. Along with belt systems also goes the inspection of tensioner pulleys and bearings.

Air filters

An electric automobile may have a cabin air filter for filtering the air conditioning air. It won’t have an engine air filter to replace like an ICE vehicle does though.

The list goes on and on

There are many other car parts that you will no longer need to worry about if you switch to an electric car. We haven’t even mentioned mufflers. Replacing mufflers is such a big business that there are multiple chain companies across the country that specialize in it. There is a huge amount of maintenance and expense associated with the upkeep of a vehicle that uses an internal combustion engine. Once everyone sees how much can be saved in the long run by operating an EV, I think the choice to switch will be obvious.
