The remedy includes warning labels and an over-the-air (OTA) update that lowers windows after a collision.Separately, Tesla is immediately recalling 2.74 million China-made Model 3 and Model Y vehicles for an OTA software update to enhance driver-attention monitoring while assisted steering and other driver-assistance functions are engaged, reducing the risk of collisions if drivers fail to respond promptly.(Reporting by Beijing newsroom; Editing by Joe Bavier)
