Tesla faces investigation in the United States over problems with its door opening system.

Tesla is facing a new problem in the United States after the US safety agency (NHTSA) notified the brand of the opening of an investigation into serious defects affecting the rear door opening system of the Model Y, the best-selling car from Elon Musk's brand. The NHTSA's safety office has launched the investigation after receiving nine complaints from drivers who were unable to open the doors to remove children from the back seats, and who had to break the window to access the interior of the car and free them.

According to initial reports, this problem could be caused by the Model Y's batteries, which would not send enough voltage to the door opening system, rendering the car's electric handles useless, preventing them from opening. Furthermore, the cars in which the incident has been reported did not emit any alert or warning signal due to low battery or an error in the door opening system. Opening the doors from outside the car requires an external power source or a manual door unlocking system that must be activated from inside the vehicle and is not feasible if the driver has already exited.

The investigation affected 174,290 Model Y units manufactured from 2021 onwards, and follows another investigation initiated by Bloomberg, which indicated that several people had been injured or even killed in recent years after Tesla vehicle doors became inoperable. In this regard, the NHTSA has received more than 140 complaints from Tesla users since 2018, regarding an issue affecting several of the brand's models.
