Reliability Comparison
- Consumer Reports Surveys: Recent data from Consumer Reports indicates that EVs have had more problems compared to conventional gasoline-powered cars. On average, EVs from the past three model years have had 42% more problems than gas-only vehicles, although this is an improvement from previous years when EVs had nearly 80% more problems. Plug-in hybrids have even more reliability issues, with 70% more problems compared to gasoline vehicles, improving from 146% more issues in previous years.
- Recent Study in Nature Energy: A new study published in Nature Energy suggests that the reliability of battery electric vehicles (BEVs) has increased significantly. According to this research, BEVs now have comparable longevity to conventional internal combustion engine vehicles, with a lifespan of about 18.4 years and the ability to travel approximately 124,000 miles in their lifetime.
- Hybrid Vehicles: Notably, hybrid vehicles (without plug-in functionality) have been found to be more reliable than both conventional gasoline-powered and electric vehicles, with 26% fewer problems than gas vehicles.
In summary, while EVs are becoming more reliable, they still generally experience more problems than gasoline-powered vehicles. However, there is evidence that EV reliability is improving rapidly, and some studies suggest they may now offer comparable longevity to conventional vehicles.
