When asked whether the company has requested refunds from suppliers, a Tesla spokesman referred to a company statement, which said Tesla had asked fewer than 10 suppliers for a reduction in total spending on projects that started in 2016 and are not complete.
The memo was sent by a Tesla global supply manager and described the monetary request as "essential to Tesla's continued operation", and "characterized it as an investment in the vehicle company" according to the Journal.
Still, industry analysts said it is unusual for automakers to request refunds for two previous years, as Tesla has demanded.
Becoming cash-flow positive is the primary goal of Chief Executive, Elon Musk, who said he wants to avoid raising additional cash, and turn a profit in the second half of the year.

Trump says he doesn't think Russian Federation is still targeting U.S
It was easily Trump's worst moment as president, even if it wasn't - as some over the top Democratic critics said, treasonable. But Trump also appeared to undercut his statement and suggested "other people" could have interfered with the election as well.
In the memo to suppliers last week, Tesla asked for a meaningful amount of money to help it become profitable. The firm is less focused on one-time reductions for this quarter as it is on reaching a "more sustainable long-term cost basis".
Tesla has since commented on the WSJ story, telling Reuters that it has contacted a small number of suppliers as part of a broader effort to secure price cuts. Musk has pushed back on naysayers, arguing that the company will be profitable this quarter and next.
This development comes at a critical time as the company is struggling to boost production of its first mainstream model, the Model 3.
As pressure mounted to ramp up Model 3 production, Musk set up a tent outside Tesla's plant in Fremont, California.
Under fire, Donald Trump says he misspoke on Russian Federation election meddling
The president broke that silence with several tweets Tuesday morning, including one doubling down on what happened in Helsinki. Even some usually friendly Fox News hosts, including Fox & Friends' Brian Kilmeade, implored Trump to clarify his comments.
While it may be a bad sign, going after suppliers is just the latest thing Tesla is doing to get cash and get the Model 3 to Tesla's eager buyers.
