Minimalist retractable door handles turned a signature function of electrical automobiles (EVs), but the controversial designs are now at the centre of China’s greatest automotive recall, affecting more than 4 million automobiles.

Tesla said it will place warning labels on the recalled automobiles and challenge a software program replace to robotically decrease a car’s home windows after a collision.

It is not clear if the affected corporations plan to make a related recall for the relaxation of the world.

In February, Chinese authorities announced a ban on hidden door handles.

Under new guidelines due to take impact on 1 January 2027, vehicles will only be allowed to be offered in China if they have a mechanical launch on both the inside and outside of their doorways.
