2021 Ram 3500 problems
The Ram pickup (marketed as the Dodge Ram until 2010) is a full-size pickup truck manufactured by Stellantis North America (formerly Chrysler Group LLC and FCA US LLC) and marketed from 2010 onwards under the Ram Trucks brand. The current fifth-generation Ram debuted at the 2018 North American International Auto Show in Detroit, Michigan, in January of that year.
Previously, Ram was part of the Dodge line of light trucks. The name Ram was first used in 1981 model year Dodge Trucks in October 1980, following the retiring and rebadging of the Dodge D series pickup trucks as well as B-series vans, though the company had used a ram's-head hood ornament on some trucks as early as 1933.
Ram trucks have been named Motor Trend magazine's Truck of the Year eight times; the second-generation Ram won the award in 1994, the third-generation Ram heavy-duty won the award in 2003, the fourth-generation Ram Heavy Duty won in 2010 and the fourth-generation Ram 1500 won in 2013 and 2014, and the current fifth-generation Ram pickup became the first truck in history to win the award three times, winning in 2019, 2020, and 2021.
