Tesla share price continues to tumble down towards its bond price following headlines from Reuters, citing sources, that the car-making company will shutter production of the Model 3 from May 26th to 31st for “fixes to its assembly.”

Reuters notes that two sources confirmed that the next stoppage on the general assembly line at the Fremont, California, plant was scheduled for May 26-31.

The production-challenged electric vehicle maker previously warned of 10 days of temporary shutdowns this quarter as the company addresses manufacturing problems that have delayed volume production of the Model 3 sedan, which is seen as crucial to Tesla's long-term profitability, Reuters adds.

This follows the previous production halt on April 17th to make “on-the-fly fixes”, as well as a prior stoppage in February.  The April shutdown, combined with the upcoming one, would add up to the planned 10 days of stoppages.

Tesla has been struggling to find solutions to manufacturing bottlenecks on the new assembly line that produces the Model 3, a sedan intended for volume production. An over-reliance on robots has complicated that task, Chief Executive Officer Elon Musk has acknowledged.

Musk, Tesla's billionaire founder, told employees it was “quite likely” the company would reach a rate of 500 Model 3s per day this week, or 3,500 a week, automotive news website Electrek reported on Tuesday, citing an internal email. Musk also told staff to alert him of “any specific bottlenecks” on the production line.

While Musk has said the planned stoppages are intended to give the company time to perform upgrades that will help it reach a goal of building 6,000 vehicles per week by the end of June, the market is becoming increasingly skeptical, especially since in order to meet the production goal of 6,000 cars per week by the end of July, Musk said last month that all Model 3 production would begin working around the clock.
