Tesla owes roughly $1.77 million in overdue payments, a French metal supplier alleged in a new lawsuit filed on Tuesday.

According to court documents, Lebronze Alloys has supplied a metal part for Tesla's electric motors since 2016. However, efforts to collect the 1,559,420.06 euros (approximately $1,768,460.32) that the company owes have been unsuccessful, the company alleges in the lawsuit.

"LBA made numerous efforts to get Tesla to pay the amounts Tesla owed to LBA. LBA convened meetings, sent e-mails and letters, and initiated numerous telephone calls in an effort to get Tesla to pay what it owed, to answer any questions Tesla may have had, and to resolve any issues," the lawsuit, which was filed in California's Northern District, reads. "In addition, LBA demanded reasonable assurances of performance by Tesla."

In 2016, Tesla agreed to buy parts from Lebronze Alloys for up to 1.5 million vehicles, according to contracts filed as exhibits in Tuesday's suit. That agreement was amended in February 2019, with the forecast trimmed to just 250,000, according to another exhibit.

"On April 17, 2019, Tesla, without notice, requested an immediate telephone conference call, during which Tesla purported to give verbal notice of termination of the Agreement and the Amended Agreement, without advance notice and contrary to the terms of the Agreement and the Amended Agreement," the lawsuit says. "This constituted a breach, repudiation and anticipatory breach of the Agreement and the Amended Agreement."

Lebronze Alloys is asking the court to force Tesla to pay for the alleged overdue charges, as well as reimbursement for its legal fees and other damages.

It's not the first time Tesla suppliers have been unhappy with Elon Musk's electric-car maker. The Wall Street Journal reported in July 2018 that Tesla had sent a memo to suppliers requesting refunds. The memo said that the money was "essential to Tesla's continued operation," according to The Journal.

Later that year, in August 2018, 18 of 22 executives at automotive supply companies said in a survey reported on by The Journal that Tesla was a financial risk to their businesses. Eight of the 22 said they were worried about a Tesla bankruptcy.

Tesla's cash situation has come back into the forefront of investors' minds again recently, as disappointing delivery numbers and quarterly earnings reports have sent the stock cratering to less than $200 per share.

Shares of Tesla fell about 1% in after-hours trading on Tuesday following news of the lawsuit.
