Tesla Motors Inc (NASDAQ:TSLA) has announced that it will delay the start of production of its Model X by one year. The automaker made the announcement in its annual report, which was filed on Thursday. The news comes less than a month after the controversy involving a reporter’s review of the Model S. Tesla Motors Inc (NASDAQ:TSLA) released the logs from the reporter’s trip not long after the article was released, showing that the trip didn’t happen exactly as the reporter had said.

Tesla had previously been planning to begin production on the Model X later this year. The company’s report now says production won’t begin until late next year. It also says that Tesla Motors Inc (NASDAQ:TSLA) has met a steady production rate of 20,000 vehicles per year for its Model S.

The company told CNET that there is currently a waiting period of about nine months for consumers who want to order the Model S. The automaker is now working at shortening that fulfillment period to about three months.

The Model X is a crossover electric vehicle which was designed with a platform somewhat like the Model S, although it will have four-wheel drive. Also the range of the Model X will be shorter than the Model S’ range because of the different shape of the vehicle and the heavier weight.

Tesla did not explain why it was delaying production on the Model X, although the company has now been producing the Model S long enough to have learned some lessons about how to produce electric vehicles.

Shares of Tesla Motors Inc (NASDAQ:TSLA) rose almost 2 percent in Monday trading and continued edging higher in after-hours trades.
