San Francisco: Electric-car maker Tesla has reportedly slashed the warranty on its four-year used cars to just one year. The company has not given any explanation for the change.

According to Electrek, the automaker previously offered a two- to a four-year warranty on used Model S and X vehicles, but now only offers a warranty of one year or 10,000 miles over the original policy.

Tesla China website is also now adjusting the additional warranty period for used cars to one year or 20,000 km. The new warranty terms are significantly less beneficial to consumers buying used EVs directly from Tesla.

The Elon Musk-owned company also recently cancelled its seven-calendar-day, no-questions-asked, full-refund return policy.

New buyers wishing to return a Tesla vehicle will now have to go through the customer service department, and it’s unclear what types of situations may warrant a full or even partial refund after purchase.
