Tesla plans to slash by 40 percent its orders for parts for the new Model 3 mass-market sedan from Taiwanese auto component maker Hota Industrial from December, according to a media report.

Tesla shares tipped 2 percent to $319.50 in early Friday trading.

Shares of the parts maker Hota dropped nearly 9 percent after the Economic Daily News reported, citing Hota Chairman Shen Kuo-jung, that Tesla had told the firm orders would be cut to 3,000 sets per week from 5,000 sets starting December, due to a “bottleneck” in the production of Model 3.

Tesla may delay scheduled weekly shipments of 10,000 parts in March by a few weeks until May or June, the report added.

Hota, which makes gears and axles for vehicles, and Tesla did not immediately respond to a request for comment.

Earlier this month, Tesla said production bottlenecks had left the company behind its planned ramp-up for the new Model 3 sedan. It began production of the model in July.
