According to documents posted by the National Highway Safety Administration, "the electronic power assist steering (EPAS) system may experience a loss of power steering assist when driving on rough roads or after hitting a pothole." The issue doesn't necessarily remove all power steering assist or render the vehicle inoperable.
Some Tesla owners will get a warning that their car has a problem. They will hear an audio warning and see a warning on the car's instrument cluster. The good news is that this problem can be fixed with a software update that Tesla will send out over the air. This means that most people won't have to take their cars to the dealer for repair. In fact, Tesla says 97% of cars on the road with this problem have already been updated.
Interestingly, the problem was caused by a firmware update that was released on October 11, 2022. This update recalibrated "values for the electronic power assist steering (EPAS) system to better detect unexpected steering assist torque." A week later, Tesla identified an increasing rate of alerts related to the updated EPAS calibration values, which is how they knew there was a problem. The company rolled back the software update on October 19. In total, between October 11 and November 1, Tesla says it identified 314 vehicle alerts in the United States for this issue.
