Plant History: Warren Truck Assembly Plant has been making trucks since 1938. A total of 6,767,213 trucks were produced from 1938 through 1985. Dodge Dakota was introduced in 1987 and Ram 1500 was introduced in 1993. The second generation Dakota was launched in 1996. The 2002 Ram 1500 was launched in September 2001 with the Quad Cab. The Mitsubishi Raider began production in September 2005. Production of 2009’s most award-winning light-duty pickup truck, the Ram 1500, began in 2008. Production of the Dodge Dakota ended on Aug. 23, 2011, with more than 2,750,000 built at the plant. The 2013 Ram 1500 launched on Sept. 6, 2012, and subsequently won the 2013 Motor Trend Truck of the Year. The Ram 1500 also won the 2014 Motor Trend Truck of Year, citing the all-new EcoDiesel V-6 engine and making it the only consecutive winner in the history of the award. The Ram 1500 EcoDiesel launched on Jan. 21, 2014.

On Nov. 15, 2012, the Company announced that a third crew of about 1,000 jobs would be added in March 2013. The third crew started on March 4, 2013.

In July 2016, FCA announced that production of the next generation Ram 1500 would move to the Sterling Heights (Mich.) Assembly Plant as part of a larger industrialization plan to realign its U.S. manufacturing operations to fully utilize available capacity to expand the Jeep_® and Ram brands. With the launch of the 2019 Ram 1500 in Sterling Heights in March 2018, Warren's operating pattern changed to two shifts to continue building the 2018 version of the light-duty truck. It was renamed the Ram 1500 Classic in the 2019 model year. 

FCA announced on Jan. 8, 2017, that it would invest a total $1 billion to retool and modernize Warren Truck to produce the all-new Wagoneer and Grand Wagoneer and the south plant of the Toledo (Ohio) Assembly Complex to build an all-new Jeep pickup truck, which launched in April 2019. 

On Feb. 26, 2019, FCA confirmed that the investment announced in 2017 would increase to $1.5 billion and include tooling to produce electrified versions of the Wagoneer and Grand Wagoneer. As part of the announcement, the Company also confirmed that production of the Ram 1500 Classic would continue. It is expected that 1,400 new jobs will be added. With this announcement, production of the all-new Ram Heavy Duty would continue at its current location in Saltillo, Mexico. (FCA had announced in January 2018 that heavy duty production would move from Saltillo, Mexico, to Warren.)

The Wagoneer and Grand Wagoneer began shipping to dealers on Sept. 25, 2021.

On Sept. 11, 2024, Stellantis announced that it would invest approximately $97.6 million at the plant for production of a future electrified Jeep Wagoneer. 

In Oct. 2024, the Company concluded production of the Ram 1500 Classic.
