Multiple web search results state that a trade agreement implemented previously lowered tariffs on autos and auto parts to 15 percent. This is reported by independent sources (e.g., News18, web_search) and is consistent with the claim's core fact.

Multiple web search results from AP News, BBC, and other sources independently report that Donald Trump threatened or announced an increase to 25% tariffs on EU vehicles, citing non-compliance with a trade deal. The evidence is consistent across these independent news reports.

Multiple web search results independently report that a trade deal was reached between the US and the EU involving Ursula von der Leyen and Donald Trump, and that this deal set tariffs at 15% on European goods. The timing (last July) is consistent with the general timeline provided by the sources.

Multiple web search results report that a Supreme Court ruling influenced tariff rates. One source specifically mentions Trump using different legislation (Section 122 of the 1974 Trade Act) to impose a temporary 10% tariff following a Supreme Court ruling, contradicting the claim's specific sequence (15% to 10% due to new taxes). However, the core elements—Supreme Court ruling, tariff change, and 10% rate—are corroborated by multiple sources, making the claim substantially accurate in its factual components.
