Model S Steering Assist Motor Bolt Recall

In order to ensure the safety of our customers, Tesla will proactively retrofit a power steering component in all Model S vehicles built before April 2016. There have been no injuries or accidents due to this component, despite accumulating more than a billion miles of driving.
We have observed excessive corrosion in the power steering bolts, though only in very cold climates, particularly those that frequently use calcium or magnesium road salts, rather than sodium chloride (table salt). Nonetheless, Tesla plans to replace all early Model S power steering bolts in all climates worldwide to account for the possibility that the vehicle may later be used in a highly corrosive environment.
If the bolts fail, the driver is still able to steer the car, but increased force is required due to loss or reduction of power assist. This primarily makes the car harder to drive at low speeds and for parallel parking, but does not materially affect control at high speed, where only small steering wheel force is needed.
If you own a Model S affected by this voluntary recall, there is no immediate action you need to take at this time, and you may continue to drive your car. Tesla will contact you to schedule an appointment when parts are available in your region. The repair will typically take around an hour.
Thank you for being a Tesla customer, and we apologize for this inconvenience. If you have any questions, please contact us.
