Before GM fully transitions its production strategy — a process that could take years — the automaker and others with global supply chains face potentially thousands of dollars in additional vehicle costs due to the new tariffs. Currently, the Chevrolet Silverado pickup truck's starting price is $38,995, while the GMC Sierra starts slightly higher at $40,295. Meanwhile, Nissan opted to maintain two production shifts at its Smyrna, Tenn., plant — reversing an earlier decision to scale down to one shift. The Japanese automaker cited the need to bolster domestic output amid tariffs affecting imported vehicles from Mexico and Japan. Stellantis — which also owns Jeep and Ram — is launching a new sales initiative that extends employee-level pricing to all US customers on most of its vehicle lineup, according to the Wall Street Journal.
