Tesla has issued a recall for 40,168 vehicles due to a software issue that could result in the loss of power steering assistance, but the automaker states that it has already deployed a wireless over-the-air (OTA) update to address the problem.
In certain Model S and Model X vehicles from 2017-2021 that received the 2022.36 firmware version, changes in “calibration values” for electric power steering could generate external forces, such as impacts from potholes, that would be interpreted as unexpected steering.
Such misinterpretation could lead to a reduction in electric assistance, increasing the effort required to drive, especially at lower speeds, according to the report. The loss of assistance will trigger audio and visual alerts.
Tesla has rolled out an OTA update to recalibrate the power steering system. While Tesla generally sends these updates directly to customers’ vehicles, the automaker is also going through the mandatory recall process and sending letters to owners to confirm the solution. These letters are expected to be sent out by December 31.
This is the latest in a series of recalls over the past two years that have been addressed with a straightforward OTA solution, quite different from recalls requiring in-person part replacements.
In September, Tesla recalled over 1 million vehicles for an issue with the electric window that could have pinched fingers. Before that, it recalled 26,681 vehicles for “reduced defrosting performance.” Both issues were addressed with OTA updates that did not require service center visits.
However, Tesla has still had to deal with some significant recalls that necessitate in-person service visits. A recall of 356,309 Model 3 sedans earlier this year involved the inspection and, if necessary, replacement of rearview camera wiring harnesses, while another involving the Model S required the same for front latch assemblies.
