Hertz is selling 20,000 EVs due to high repair costs, serving as a warning about the "hidden" expenses of electric vehicle ownership, including expensive repairs, charging infrastructure, insurance, maintenance, and depreciation. EVs, particularly Teslas, are found to be more costly to repair than gas-powered cars, and charging infrastructure and maintenance can also add to the overall ownership expenses. While federal incentives can make EVs more affordable, potential buyers should consider these hidden costs before making the switch from gas to electric.
