BEIJING, Dec 31 (Reuters) - Tesla will fix

software in 77,650 China-made Model 3 and Model Y cars over

safety hazards, China's market regulator said on Tuesday.

The action, due to software issues that may fail to display

the monitored tyre pressure immediately after the vehicle

starts, is described as a product recall under Chinese

regulations, the regulator said. It was not immediately clear if

drivers might need, or would be eligible, to return vehicles to

Tesla for refunds.

The U.S. electric vehicle maker is also recalling 63

imported Model S and Model X cars in China over issues with the

driver's frontal airbag.
