The average maintenance costs for plug-in hybrid electric vehicles (PHEVs) over a 10-year period can be estimated based on mileage and annual maintenance data reported by sources.
Key Figures:
- According to Consumer Reports data summarized by GreenCars, the lifetime maintenance cost of an average PHEV (calculated at 200,000 miles) is about $4,600, which breaks down to roughly $460 per year if we assume driving 20,000 miles annually over 10 years.
- This $4,600 figure compares very favorably to conventional gasoline vehicles, whose maintenance costs average about $9,200 over the same mileage.
- On a per-mile basis, maintenance and repair costs for PHEVs and all-electric vehicles are around 3 cents per mile, about half the 6 cents per mile typical for gasoline cars.
- A real-world example from a luxury PHEV, the 2025 Lexus NX 450+ plug-in hybrid, shows maintenance and repair costs of approximately $1,412 annually and about $7,061 total over five years. Extending this estimate linearly to 10 years would imply around $14,120, but as this is a luxury vehicle, typical PHEVs may have lower costs.
- Scheduled maintenance for electric and plug-in hybrids tends to be lower on average than for internal combustion engine vehicles, with some fleet data showing EVs averaging about 6.1 cents per mile in maintenance cost versus 10.1 cents for gasoline vehicles. PHEVs typically fall between these two.
Summary:
| Metric | PHEV Average | Gasoline Vehicle Average |
|---|---|---|
| Maintenance cost per mile | ~3 cents | ~6 cents |
| Total maintenance cost per 200,000 miles | ~$4,600 | ~$9,200 |
| Approximate annual maintenance cost (20,000 miles/year) | ~$460 | ~$920 |
| Example luxury PHEV 5-year maintenance cost | ~$7,061 | — |
Thus, over a 10-year ownership period and approximately 200,000 miles, the average PHEV owner can expect maintenance and repair costs around $4,600 to $5,000, roughly half that of a conventional gasoline-powered vehicle. Luxury PHEVs may have higher maintenance costs, closer to $1,400 annually. The complexity of PHEVs does not generally translate to higher maintenance expenses due to fewer issues with engines and brakes compared to conventional cars.
In conclusion, average maintenance costs for PHEVs over 10 years are significantly lower than gas vehicles, typically around $4,600 based on mileage-driven estimates, but can vary depending on vehicle class and usage.
