Tesla Exposed for Long-Term Payment Delays Exceeding $110 Million

【PCauto】 Tesla is facing a severe supply chain trust crisis. Since July 2025, Tesla has been facing a growing crisis of trust among its suppliers. Two U.S.-based auto parts vendors—California’s DPF Tech and Colorado-based Ultra Energy Solutions—have filed for bankruptcy, collectively claiming that Tesla owes them a total of $110 million in unpaid invoices.

These cases have exposed only the tip of the iceberg in the strained relationship between Tesla and its suppliers, and have prompted an investigation by the U.S. Congress. According to newly released court documents, Tesla’s average payment period has extended to 123 days—far above the industry norm.

Two Bankrupted Suppliers Speak Out

DPF Tech outlined its difficulties with Tesla in a lawsuit filed in the U.S. District Court for the Northern District of California. Since 2019, the company has been owed $62 million in unpaid receivables. In its bankruptcy filing, the CEO stated: “Even after product acceptance, Tesla refused to pay for 18 months, citing vague ‘quality disputes’—forcing us to lay off 85% of our workforce.”

Ultra Energy Solutions faced a similar fate. The company was never paid for $49 million worth of raw materials used in Tesla’s 4680 battery production. Its plant was eventually auctioned off to a subsidiary of China’s CATL.

These cases validate warnings issued by the Original Equipment Suppliers Association (OESA), which has cautioned that when Tesla accounts for more than 30% of a small supplier’s annual revenue, delayed payments can trigger a disastrous chain reaction.

Federal Court Records Reveal Tesla’s Typical Practices

A pipeline welding contractor in Colorado filed for bankruptcy after completing work at the Austin Gigafactory and receiving only $650,000 in subcontracting fees—leaving hundreds of thousands unpaid.

Even more startling was the case involving Full Circle, a security equipment supplier. After Tesla failed to pay nearly $600,000, the company filed for bankruptcy, only for Tesla to countersue during the hearing. Eventually, Tesla was released from payment obligations through a settlement.

Over the past five years, Tesla has faced over $110 million in lien claims in Texas alone, with $24 million still outstanding.

This pattern appears to extend to Elon Musk’s other ventures as well. Since acquiring Twitter, at least seven suppliers have gone bankrupt due to unpaid bills.

Tesla’s Accounts Payable Cycle Far Exceeds Industry Average

Tesla’s Q2 2025 earnings report shows it holds $28.6 billion in cash, yet its accounts payable cycle has lengthened from 97 days in 2024 to 123 days—37% higher than the industry norm of 60 to 90 days.

Stanford University professor Henry Thompson commented, “Tesla may be leveraging its market dominance to impose unfavorable terms on small businesses. If courts determine the company has willfully delayed payments, it could face treble damages as punitive compensation.” The U.S. House Small Business Committee has summoned Tesla to a hearing in September 2025, which may prove to be a turning point in the case.

Production Disruptions

The impact on Tesla’s production system is already visible. In 2023, German supplier Elring Klinger terminated its contract over unpaid Model Y orders, leading to a two-week shutdown at the Berlin plant.

According to the latest white paper from OESA, continued payment issues are prompting suppliers to charge Tesla a 20–30% risk premium on orders. More concerning, some battery material suppliers have begun demanding advance payments.

With key technology suppliers like DPF Tech filing for bankruptcy, the Cybertruck production ramp-up may face delays. The DPF Tech lawsuit is scheduled for trial in California this October, while the Ultra Energy case has been moved to Delaware due to arbitration clauses.
