Tesla Model S steering defect prompts recall for 123K vehicles

Excessive corrosion in powers steering bolts can make the car more difficult to maneuver at low speeds.

Tesla has apparently issued its largest recall ever, addressing a steering system defect in Model S sedans built before April 2016.

The company sent a notification to owners warning that certain power steering bolts are prone to excessive corrosion and eventual failure. Unsurprisingly, the issue is said to be concentrated in snowy regions that expose vehicles to road salt containing more corrosive additives such as magnesium chloride.

"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," the notice explained.

The California-based company is not handling the defect as a regional rust-belt repair campaign, instead promising repairs for the entire fleet of more than 120,000 vehicles globally.

"There have been no injuries or accidents due to this component, despite accumulating more than a billion miles of driving," Tesla said in its notification.
