Tesla (TSLA  ) is recalling nearly 1.1 million vehicles due to faulty window software. According to the company, the window obstruction detection software sometimes fails to react to obstructions, meaning the power windows could potentially cause an injury.

On Thursday, September 22, the National Highway Traffic Safety Administration (NHTSA) posted a letter revealing that the carmaker had discovered the software issue during internal testing in August. The tests showed that the power window software produced "greater than expected variations in response to pinch detection."

Tesla says it hasn't received any claims or reports of adverse effects related to the issue, but the faulty software is in violation of federal safety standards.

The 1,096,762 Teslas covered in the recall include select Model 3, Model S, Model X, and Model Y vehicles. Model 3 sedans manufactured since mid-2017, Model S sedans manufactured since the beginning of 2021, Model X SUVs manufactured since early 2021, and Model Ys manufactured since 2019 are being recalled.

The issue was addressed in vehicles in production and vehicles awaiting delivery as of Sept. 13.

To address the problem, Tesla told the NHTSA that it will be administering an over-the-air update to its software that "enhances the calibration of the vehicle's automatic window reversal system behavior."

Tesla owners can check if their vehicle is covered by going to the NHTSA website.

After the NHTSA and Tesla documents were made public, Tesla CEO Elon Musk took to Twitter (TWTR  ) to complain about the wording of the recall announcements.

"The terminology is outdated & inaccurate. This is a tiny over-the-air software update. To the best of our knowledge, there have been no injuries," Musk wrote.

According to Reuters, both the NHTSA and Tesla referred to the event as a recall. In the past, Tesla faced pushback from the safety regulator for failing to file a recall notice for other over-the-air software updates.

"Any manufacturer issuing an over-the-air update that mitigates a defect that poses an unreasonable risk to motor vehicle safety is required to timely file an accompanying recall notice to NHTSA," the agency wrote in a letter to Tesla last October.

The agency was writing in regards to an update Tesla had made to its Autopilot systems following nearly a dozen collisions between emergency vehicles and Teslas on Autopilot.
