(Reuters) -Tesla's electric vehicle registrations in California dropped 15.1% during the first quarter, according to industry data, signaling growing challenges for the Elon Musk-led automaker in the crucial U.S. market.
The company's quarterly sales globally fell 13% to the lowest in nearly three years, hurt by a backlash against CEO Musk, rising competition and as customers wait for a refresh of its highest-selling electric vehicle Model Y.
