Tesla has issued an over-the-air (OTA) recall affecting nearly 55,000 2021-2023 Tesla Model X vehicles over concerns the vehicle controller will not detect and warn the driver of low brake fluid levels. As is typical with most National Highway Traffic Safety Administration (NHTSA) recalls and Tesla, the company has already fixed the issue through a free OTA software update.
According to the recall document posted to the NHTSA website, the issue was first discovered in several Model X vehicles in September 2023, where a visual indicator for low brake fluid was not functioning. The Brakes Integration team initiated an investigation between September 19 and September 27, during which they examined sensor data, performed tests to confirm the issue, and assessed design specifications to identify the root cause.
On September 27, the team determined that an incorrect setting in the vehicle controller’s threshold range was causing the problem. Just one day later, on September 28, Tesla initiated an OTA software update to correct the issue. Tesla says as of October 10, 2023, there have been no reported crashes, injuries, or deaths related to this issue.
The OTA update that corrected the issue was 2023.32.7 or later, a non FSD Beta branch. For affected Model X vehicles with FSD Beta, Tesla says a fix will be included in the next release, a date for which was not provided.
