Also this week, Tesla recalled nearly 285,000 of its Model 3 and Model Y cars that were built in China due to a software glitch.
That number translates to "most of the vehicles it has delivered the country over recent years," wrote Wedbush analyst Daniel Ives in a note on Sunday.
The recall is to fix autopilot safety problems that Chinese regulators spotted.
Vehicles within the scope of the recall may cause the drivers to incorrectly activate the active cruise function in some situations, according to the State Administration for Market Regulation in China.
