General Motors is expecting to receive $500 million in refunds for tariffs paid on imported vehicles and vehicle parts. A ruling by the Supreme Court found that certain auto-related tariffs imposed by the Trump administration were illegal, leading to the new refunds. The company is now expecting tariff costs in the range of $2.5 billion to $3.5 billion in 2026, down from original estimates expecting costs of $3 billion to $4 billion.
