The move, sparked by fears over a loss of power steering assist on some models, may affect the company’s share price—which has already been hit as a result of Musk’s new job as Twitter boss.

The recall relates to the 2017 to 2021 Model S and Model X vehicles, according to news agency Reuters, amid concerns that drivers may experience a loss of power steering assist when driving on rough roads or after hitting a pothole.

The Texas-based electric vehicle manufacturer has released an over-the-air software update to recalibrate the system after it began rolling out an update on October 11, the agency added.

The National Highway Traffic Safety Administration said a loss of power steering assist can require greater steering effort, especially at low speeds, increasing the crash risks.

But, Tesla said it is unaware of any injuries or deaths related to this condition, Reuters reported.

The automaker said that as of November 1 more than 97 percent of the recalled vehicles have installed the update that has already addressed the recall issue.

The recall announcement comes as Tesla shares fell below $200 on Monday, plunging just over five percent to $197.08.

MarketWatch published a report earlier that day noting that shares of Tesla Inc. were heading towards a drop below $200, which would be the first sub-$200 mark in 17 months.

The article noted that investors may be demonstrating concern that Musk would be distracted as a result of his new role at Twitter.

Newsweek has reached out to Tesla for comment.

Musk had previously shelled out for a 9.2 percent stake in Twitter, although he had decided not to take a seat on the board. But back in April, Musk surprised the tech world when he offered to buy 100 percent of the shares in a deal valuing the social media giant at around $43 billion. The move sent Twitter shares surging by as much as 10 percent that day in pre-market trade.

However, the news had other ramifications.

Tesla shares fell sharply upon the announcement, as reported by the The Telegraph. And the paper published an opinion piece on Monday, by commentator Andrew Orlowski, saying Musk’s acquisition of Twitter “might be the greatest mistake he has ever made.”

He noted the huge job Musk has taken on and described “the distraction it creates for Musk, and the potential consequences for his other business operations.”

These fears may be being borne out in reality. In fact, as a CNBC report pointed out on Friday, November 4, since Musk first announced his intention to buy Twitter, shares in his electric vehicle maker had dipped by more than 35 percent. However, as the article noted, the Nasdaq Composite was also down, but by about 18 percent over the same time period.

Monday’s losses have brought that Tesla shares down closer to 40 percent.

Musk first announced he had officially agreed to buy Twitter on April 25. Tesla shares closed that day at $332.67, and closed on Friday at $207.47 concluding his first full week as boss of Twitter.

After the further dip on Monday, to below $200, analysts will be watching Tesla’s shares closely on Tuesday after the NASDAQ Stock Exchange opens at 9.30 a.m. EDT.

Musk has a number of other businesses to run too, including rocket company SpaceX and tunneling firm The Boring Company, although they are both private companies and so do not have publicly-traded shares.
