Rivian filed suit against the United States government Friday, demanding a full refund of tariff payments the electric-vehicle maker says run into the tens of millions of dollars.

The lawsuit targets duties levied under the Trump administration on imported parts and materials, which Rivian argues were applied unlawfully or in excess of what the company legally owed.

Rivian said in a statement reviewed by the Wail that it is owed reimbursement for tariff costs it absorbed while scaling production at its Normal, Illinois assembly plant. The company declined to specify the precise dollar figure beyond “tens of millions.”

The action puts Rivian among a field of manufacturers that have turned to federal courts to contest the reach and application of Trump-era trade levies, with cases spanning automotive, electronics, and consumer-goods sectors.

Rivian recorded a net loss of roughly $4.7 billion in 2025, making cost-recovery actions a material concern for the company's finances.

The case is expected to be assigned to a federal court in the coming days. No initial hearing date has been set.
