Tesla Inc. was in the headlines again Monday with a series of announcements and news stories that include a restructuring to flatten the company’s management structure.

Chief Executive Elon Musk unveiled that news in a memo to employees, that lacked specific names or details. Musk made the announcement after the Wall Street Journal reported that Matthew Schwall, the company’s main technical contact with U.S. safety investigators, has left the company for self-driving-car maker Waymo LLC, a unit of Google parent Alphabet Inc. GOOGL, -3.45% . On Friday, Tesla said that its engineering chief, Doug Field, was taking a leave of absence to recharge and spend time with family.

“To ensure that Tesla is well prepared for the future, we have been undertaking a thorough reorganization of our company,” Musk said in the memo, according to the Wall Street Journal. “As part of the reorg, we are flattening the management structure to improve communication, combining functions where sensible and trimming activities that are not vital to the success of our mission.”

On Friday, a Model S crashed into a truck in South Jordan, Utah, after failing to slow for a red light, Reuters reported, citing local police.

The Tesla TSLA, -10.34% car was traveling at 60 miles an hour when it hit a truck from the city’s Unified Fire Authority at 6:38 p.m. Mountain time, said the police. It was not clear if the driver was using the electric car maker’s autopilot system at the time of impact, said Reuters. Tesla did not immediately respond to requests for comment, it said.

Just last week, the National Transportation Safety Board said it would begin examining the fiery crash of a Tesla Model S car that killed two teenagers in Fort Lauderdale, Fla., marking the fourth active federal probe involving the company’s vehicles, the Wall Street Journal reported.

The NTSB is investigating three other traffic incidents involving Tesla vehicles, including a fatal crash on March 23 that fueled questions about the safety of the autopilot feature, said the paper.

In yet another report on Monday, the Journal said developers of the Tesla autopilot system had expressed concern that it did not have enough safeguards to ensure drivers would remain attentive and keep their hands on the steering wheel. But executives overruled adding more sensors because of costs and worry that the technology would annoy drivers by beeping too much.

“Everyone at Tesla is not only encouraged, but expected, to provide criticism and feedback to ensure that we’re creating the best, safest cars on the road,” a Tesla spokesman said in a statement. “This is especially true on the Autopilot team, where we make decisions based on what will improve safety and provide the best customer experience, not for any other reason.”

Tesla is still struggling to meet its own production targets for the Model 3, the mass-market sedan launched last year. On a conference call with analysts following first-quarter results earlier this month, Tesla kept intact the target of producing 5,000 Model 3 sedans a week by the end of the second quarter.

Tesla has moved the goal posts for Model 3 production at least twice. A previous target called for 2,500 Model 3 sedans a week by the end of first quarter; Tesla missed that one, reporting in early April a production rate of around 2,000 a week.

During the call and in a letter to investors sharing results, however, Tesla disclosed that it paused Model 3 production in the third week of April to ”enable higher levels of output,” but in the week before the shutdown it produced a record 2,270 Model 3 sedans, its third straight week in April with more than 2,000 of the cars produced.

The call was more notable for Chief Executive Elon Musk’s refusal to answer questions on the company’s finances, resulting in a stream of analyst notes describing it as “feisty,” “odd,” “very, very bad” and “truly bizarre,” sending its stock down 7% in a single session.

Highlights From Elon Musk's Combative Tesla Earnings Call

Musk has repeatedly said the company will not need to raise capital this year, but most analysts and credit-rating firms are skeptical, given Tesla’s high cash-burn rate. Concerns have weighed on its high-yield bonds, which have been trading below 90 cents on the dollar.

The 5.300% notes that mature in 2025 last traded on Friday at 88 cents on the dollar to yield 7.472%, according to MarketAxess, or at a yield spread of 449 basis points over Treasurys, 10 basis points tighter on the day.

Tesla shares were closed down 3% on Monday and have fallen 6.2% in 2018 so far, while the S&P SPX, -2.37% has gained 2.1% and the Dow Jones Industrial Average DJIA, -1.92% has added 0.7%.
