Fiat-Chrysler Automobiles (FCA) intends to open an assembly plant in Detroit.
According to US media, the plant would begin to produce its Jeep sports utility vehicles (SUVs) in 2020, and create up to 400 jobs.
The US-Italian carmaker has not confirmed the plans.
However, the company has previously said that it wants to boost truck production and SUVs, which have enjoyed strong sales in the United States.
If it is true, the plans would be a rare domestic expansion by a US car company in an industry where competitors break on production.
FCA intends to reopen an engine plant that has been treated since 2012 as a vehicle assembly machine, reports say.
In general, sales of Fiat Chrysler in the US rise by 8% this year, with growth being driven by its Jeep line.
The gains are brought despite a comparative flat sales in the wider industry, which was selling a peak in 2016.
General Motors stated last month that the demand fell when it announced plans to stop production in five factories in North America, including four in the United States.
That move, which is part of a wider business reform that is likely to result in the loss of more than 14,000 jobs, has made a bad criticism from politicians.
It was also a blow to US President Donald Trump, who has made the car manufacturing regeneration a priority for his administration.
Ford has also announced restructuring plans, although it has not cut specific cuts.
