Electric vehicles (EVs) generally have lower maintenance costs compared to gas-powered cars due to their simpler mechanical design, which includes fewer moving parts and eliminates the need for routine services such as oil changes, transmission repairs, and fuel system maintenance. Common expensive maintenance tasks in gas vehicles—like engine tune-ups, spark plug replacements, and exhaust system repairs—are not necessary for EVs, resulting in significantly reduced upkeep expenses over time.
However, there are some exceptions and caveats to this general trend:
- Battery Replacement Costs: One of the most substantial potential expenses for EV owners is the eventual replacement of the electric vehicle’s battery pack, typically required after 8-10 years or 100,000-200,000 miles. Battery replacement costs can range widely, from about $5,000 up to $20,000 depending on the vehicle model. This large one-time cost can exceed typical maintenance expenses for gas cars at that time point, although it tends to be offset by lower costs before and after.
- Higher Labor Costs for Some Repairs: While EVs require less frequent replacements of mechanical components, their electrical systems and components can involve higher labor costs during repairs or maintenance when needed. Still, because these components are replaced less often than engine parts in gas cars, overall service costs remain lower on average.
- Early Years Maintenance: In the first few years of ownership, EVs typically cost much less to maintain compared to gas vehicles. For instance, average maintenance costs for EVs in the first three years are significantly lower than for combustion engines ($77 vs. $228 on average).
In summary, while on average EVs have lower maintenance costs throughout their lifetime, certain scenarios—especially expensive battery replacements—can lead to maintenance costs for EVs that temporarily exceed or approach those of gas-powered vehicles. No mainstream EV model is consistently known for having higher regular maintenance costs than comparable gas cars, but the high cost of battery replacement remains the key consideration.
Therefore, EVs mostly offer a financial advantage in maintenance over gas cars, except for the potentially large periodic cost of battery replacement and some infrequent but costly electrical repairs.
