Tesla Motors is recalling an estimated 123,000 Model S vehicles built before April 2016 because the bolts in the power steering component may be corroded and could possibly fail. In the event the bolts fail, the driver would still be able to steer the car but would be required to use "excessive force," leading to an increased risk of injury.

To fix the problem, Tesla will inform Model S owners when a retrofit is ready in their area, and schedule an appointment to install it. According to the company, retrofits typically take an hour to install.

This recall appears to be the largest in Tesla's history. In an email sent to customers, Tesla said there have not been any accidents or injuries due to the bolt issue. The company also wrote that the bolt problem, "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."
