Tesla is recalling 15,000 Model X SUVs, citing a problem with the power steering that could increase the risk of a crash. This recall applies to most Model X vehicles built before mid-October 2016. Model X vehicles built after mid-October 2016 are not affected.
Tesla posted a note on its website addressing the recall:
We are not aware of any injuries or collisions relating to the power steering component. However, we have observed excessive corrosion on the bolts that attach this component to the steering gear in affected Model X vehicles. This corrosion has been observed primarily in very cold climates that use calcium or magnesium road salts rather than sodium chloride (table salt). If the bolts fracture from corrosion, the driver may lose power steering assist. This would not prevent the driver from steering the vehicle, but it would require more force to turn the steering wheel, especially during low speed parking maneuvers when power steering assist is at its highest use. Power steering assist decreases with increasing speed, so the driver may not notice a need for more steering force at highway speeds.
Tesla said there is no immediate action for Model X owners and they may continue to drive their car. Tesla will replace the bolts and apply a corrosion-preventative sealer in all affected Model X vehicles to account for the possibility that any vehicle may later be used in a cold, highly corrosive environment. The service will be free of charge.
If Tesla finds broken bolts they intend to replace the steering gear free of charge. Tesla said it will contact owners to schedule a service appointment.
