On Thursday, Tesla issued a recall for almost 1.1 million vehicles due to a problem with their windows. The problem is related to the windows’ automatic reversal function, the safety feature that lowers the glass if it’s being raised and encounters part of a human being.

Unfortunately for the affected Teslas, during conformity production testing, “Tesla technicians identified window automatic reversal system performance that had greater than expected variations in response to pinch detection.”

The problem affects Model 3s built between 2017 and 2022, Model Ys built between 2020 and 2021, and Models S and X built between 2021 and 2022. Tesla identified the problem in late August, and by September 12, after analyzing and validating its test results, the company made the decision to issue the recall.
