The electric car manufacturer Tesla has to install a software update for almost 1.1 million vehicles in the USA due to safety concerns.

The Federal Highway and Vehicle Safety Administration (NHTSA) on Thursday referred to a malfunction in several Tesla models with the automated closing system for the windows.

Car occupants run the risk of pinching their fingers.

Tesla vehicles have a sensor system that is designed to automatically detect resistance and stop the windows from closing.

In some Model 3, Y, S and X vehicles, however, resistors are not always reliably detected, the NHTSA warned.

Tesla said the company has no knowledge of any accidents or injuries caused by the malfunction.

The problem should now be fixed with a software update.

Affected car owners will be notified from November 15th.

Tesla had already had to launch several such recalls in the United States this year.

For a long time, the company had been running software updates without notifying owners or regulators.

In recent months, however, Tesla has become the focus of the NHTSA.

The supervisory authority initiated an investigation after several collisions between Teslas and emergency vehicles.
