Polestar’s American future looked settled in June. That’s when the Commerce Department denied the EV maker authorization to sell 2027-model-year vehicles and beyond. Now, one of its New Jersey retailers says that explanation leaves out the most important part. Prestige Imports has sued Polestar for at least $25 million. It alleges the company used the regulatory decision to mask a retreat it had been planning for years. The case could decide whether Polestar was genuinely forced out or found a really useful door marked “exit.”
