WASHINGTON, Sept 22 (Reuters) – Tesla (TSLA.O) is recalling nearly 1.1 million U.S. vehicles because the automatic window reversing system may not respond properly after detecting an obstruction, increasing the risk of wound.

The electric vehicle maker told the National Highway Traffic Safety Administration (NHTSA) that it will perform an over-the-air software update to the automatic window reversing system. The recall affects certain 2017-2022 Model 3, 2020-2021 Model Y and 2021-2022 Model S and Model X vehicles.

Tesla said it was not aware of any warranty claims, field reports, accidents, injuries or deaths related to the recall.

NHTSA said a window that closes without the proper automatic reversing system can exert excessive force pinching a driver or passenger before retracting, increasing the risk of injury.

NHTSA said the vehicles failed to meet the requirements of a federal motor vehicle safety standard on power windows.

Tesla said that during product testing in August, employees identified the performance of the automatic window reversing system showed “greater than expected variations in response to pinch detection.”

After extensive additional testing, Tesla determined that vehicle pinch and retract detection performance in the test results did not meet the requirements for automatic reversing systems.

Tesla said that starting Sept. 13, production and pre-delivery vehicles received a software update that sets power window operation as required.

The software update “improves the calibration of the behavior of the vehicle’s automatic window reversing system,” Tesla said.

Tesla shares were down 3.5% in Thursday afternoon trading.

Tesla Chief Executive Elon Musk on Twitter on Thursday criticized the description of the recall as a recall.

“The terminology is outdated and inaccurate. This is a small over-the-air software update. To our knowledge, there were no injuries,” he said.

NHTSA and Tesla, in documents released Thursday, called the campaign a recall.
