Owners of used electric vehicles are more likely to face repair bills for non-powertrain components than for the expensive battery pack, according to new industry research. Analysis of repair requests shows that faults related to charging systems are proving particularly costly, despite the overall reliability often associated with EVs.
The findings indicate a shift in the perception of common EV issues, moving away from concerns about the longevity or performance of the main traction battery. Instead, components such as the onboard charger, charging port, and associated electronics are frequently requiring attention from mechanics. These repairs, while not as headline-grabbing as a battery replacement, can still represent a significant expense for used EV owners.
Beyond charging infrastructure, the research highlights other prevalent non-powertrain issues. Brake system faults, often linked to the regenerative braking capabilities of EVs, and problems with air conditioning systems are also featuring prominently in repair logs. These components are standard across both internal combustion engine (ICE) and electric vehicles, suggesting some commonalities in wear and tear.
The relatively low incidence of battery-related repairs is a positive sign for the used EV market, addressing a key concern for potential buyers regarding the long-term viability and cost of ownership. While battery degradation is a natural process, critical failures necessitating replacement appear to be rare, at least in the current fleet of used electric vehicles.
This data offers valuable insights for both consumers and the automotive industry. For buyers considering a used EV, understanding the most likely repair points can help inform purchasing decisions and budgeting for potential maintenance. For manufacturers and service providers, it underscores the importance of robust design and diagnostics for ancillary EV systems, particularly those related to charging.
