High Repair and Insurance Costs Offset EV Fuel Savings

Although new energy vehicles (NEVs) can save on fuel costs during use, their maintenance and insurance expenses are generally higher than those of comparable internal combustion engine (ICE) vehicles. Due to automakers’ use of equipment lockouts and component key authentication mechanisms, third-party repair shops often encounter issues after replacing electronic parts: if the replacement components are not authenticated and matched with data via the manufacturer’s server, the vehicle frequently displays fault warnings or experiences limitations in core functions. Moreover, certain highly integrated electronic components—such as LiDAR units and smart sensors—are designed as integral parts of the vehicle’s body structure, meaning even minor scratches may necessitate full replacement, significantly driving up repair costs. Additionally, NEVs typically carry higher insurance premiums. Many owners report that the fuel savings they achieve are often offset by steep maintenance and insurance expenses, undermining the expected cost advantage of low operating costs. Insurers, meanwhile, face persistent pressure from high claim payout ratios for NEVs, which negatively impacts the profitability and stability of their auto insurance businesses. If premium income continues to fall short of covering claim costs over the long term, it could further exacerbate difficulties in insuring high-risk vehicle models. As the number of NEVs on the road grows and more vehicles move beyond their warranty periods, authorized third-party parts suppliers are gradually entering the aftermarket. The dissemination of repair expertise and the establishment of unified third-party service standards are expected to take hold, fostering a more mature and rational NEV aftersales ecosystem.
