The 54,676 vehicles within the recall population might have been produced with a vehicle controller that detects the sensor voltage which indicates brake-fluid levels that may not have sufficient threshold range at low-fluid levels.
According to the National Highway Traffic Safety Administration (NHTSA) Part 573 Safety Recall Report 23V-679 the safety risk comes if the sensor does not indicate a low brake fluid level. Low fluid levels might alter brake pedal feel or impact brake performance, which might result in a crash.
There are no reports of any crashes or injuries as a result of this issue.
Tesla has produced a software update to remedy the situation which can be implemented by vehicle owners through an over-the-air update.
Tesla is scheduled to have notified its stores and service centers, as well as its owners, during the week of Oct. 11th.
