A Tesla spokeswoman declined to comment Monday and said the company would be unable to meet The Times’ deadline for publication. The Times first emailed the company on Friday afternoon, asking to what extent Tesla relies on foreign components in its vehicle manufacturing, as well as whether the company was ever notified about the ICE investigation.

Tesla drew Mr. Obama’s attention in 2010 when he visited the headquarters of now-bankrupt solar panel maker Solyndra, which collapsed last year despite more than a half-billion dollars in federal loans.

Mentioning a closed auto plant nearby, Mr. Obama said thanks to the Energy Department loan to Tesla “that shuttered plant is soon going to reopen.”

“And once again, once again, it will be a symbol of promise, an example of what’s possible here in America,” Mr. Obama said. “Tesla is joining with Toyota in a venture to put a thousand skilled workers back to work manufacturing all-electric car. And this is only the beginning.”

Earlier this month, Tesla announced that it had lost $110.8 million in this year’s third quarter, about $40 million more compared with the same period in 2011.

But the news hasn’t been all bad. Production of the firm’s Model S sedan increased from five cars per week at the beginning of the quarter to 100 cars per week by the end, with production now at more than 200 cars, according to the company.

The company also said it had drawn down its $465 million federal loan and had begun paying back the government.

“We continue to maintain a strong relationship with the [Energy Department],” the company said in a statement.
