GM stopped producing the Hummer after the 2010 model. It will resume production with the 2022 Hummer EV. Sales plummeted in 2007 from 54,052 in 2006 to 43,431 in 2007 and later to 20,681 in 2008. In 2009, the sales further dropped to 5,487.  GM never produced another model after 2010. The bad reputation of the Hummer as a gas-guzzler followed it into the H3.  Even if the mileage improved with later models, people never saw the Hummer as anything more than a guzzler. If you still want a Hummer, you can go for Humvee, also known as Hummer-C. However, the Detriot-produced Humvee is for the export market.
