Because Teslas have far fewer parts than conventional cars, there are far fewer things to go wrong. As important, the electric motors that drive Tesla vehicles are among the most reliable and long lasting of any motor. There is no transmission and therefore no transmission failures. All of that leads to a long life. Reports of Teslas with 200,000 miles on their odometer are common, and there are also reports of Teslas with 300,000, 400,000 and more miles.
