NEW YORK ? Major automakers and parts suppliers came under renewed pressure after President Donald Trump said the United States would impose a 25% tariff on imported vehicles, a move industry analysts said would raise production costs and threaten new price increases for consumers.

In its initial report on the tariff order, The Associated Press said the measure was designed to promote domestic manufacturing but could squeeze companies whose supply chains stretch across North America and beyond. The new duties were set to take effect on April 3.

A day later, AP's market follow-up showed the immediate investor response, with shares of General Motors, Ford and several major suppliers falling as analysts warned that the industry's cross-border production model would make many vehicles more expensive to build.

Executives were also confronting operational decisions beyond Wall Street. CNBC later reported that some carmakers were weighing price hikes, import fees, production pauses and layoffs as they tried to absorb the added costs and protect margins.

The tariff announcement added a new layer of uncertainty to an industry already dealing with softening demand in some segments, high financing costs and the challenge of reworking supply chains that move components across multiple borders before a vehicle reaches a showroom.
