EVs Need Fewer Repairs, Right? Wrong, Says Study “This is part of an industry learning curve,” WePredict VP Renee Stephens says of new electric vehicles’ fix rate and costs at car dealerships. An expectation of consumers and a trepidation of auto dealership service departments is that the waves of electric vehicles hitting the market will need fewer repairs. “The cost of EV service is less than for gasoline-powered and hybrid vehicles, right?” Renee Stephens, data firm WePredict’s vice president-automotive, says, citing conventional thinking. But she adds: “Wrong.” Her firm’s aggregated repair data indicate EV parts and labor currently cost twice as much as other vehicles.
