vehicles because the window automatic reversal system may not react correctly after detecting an obstruction, increasing the risk of injury.

The electric vehicle manufacturer told the National Highway Traffic SafetyAdministration (NHTSA) it would perform an over-the-air software update of the automatic window reversal system.

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

Tesla said during product testing in August employees identified window automatic reversal system performance that had "greater than expected variations in response to pinch detection.".

After extensive additional testing, Tesla determined the vehicles pinch detection and retraction performance in the test results did not meet automatic reversal systems requirements.
