More than four million cars, including three million Teslas, are being recalled in China due to safety concerns over concealed door handles.The recall, which also affects a number of major Chinese carmakers, is the largest in the country this year.Some 2.98 million Chinese-made and imported Teslas are being called back.External handles that sit flush to the door panel have been popularised by the American EV manufacturer and used across its mainstream vehicle line.As such, the Model 3, Model Y, Model X and Model S are all being recalled to adhere to impending regulations.The Chinese Ministry of Industry and Information Technology (MIIT) announced in February that it will outlaw minimalist, pop-out door handles from January 1 2027 as safety concerns mount about the feature. This is after instances where the handles have lost power after being involved in a crash, making it difficult for emergency services to reach passengers inside stricken vehicles.Recalled Tesla cars will have a warning label stuck on the inside of the door and receive a software update that automatically lowers the windows after a collision. More than four million cars are being recalled in China due to safety concerns over hidden door handles, with over 2.98 million Tesla EVs being recalledXiaomi, the Beijing-based smart driving technology company, is recalling more than 390,900 cars, while Hangzhou-based Leapmotor is calling back more than 370,000 vehicles.Geely and XPeng are also recalling motors.The new rules coming into effect from next year only allow carmakers to sell cars in China if they have a mechanical release on both the inside and outside of their doors.The MIIT said that Chinese car models already approved for launch will have an additional two years to redesign their vehicles to be compliant with the new rules.The new regulations will apply to all vehicles but will mostly affect EVs, which are commonly designed with hidden handles, and will 'improve the level of automotive safety design,' the ministry said.
