2020 Ram 4500 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.

Common 2020 Ram 4500 problems
Based on complaints from owners of the 2020 Ram 4500, several common problems have been reported:
- Aftermarket Items Installation: Improper installation of aftermarket parts like alarms or exhaust systems can trigger the check engine light, affect the battery, or even prevent the vehicle from starting. Correct installation of aftermarket items is crucial to avoid these issues.
- Loose or Damaged Gas Cap: A loose, damaged, or missing gas cap can trigger the check engine light. The gas cap plays a vital role in preventing fuel evaporation and maintaining pressure in the fuel tank. If the gas cap is faulty, it can lead to fuel loss through evaporation, resulting in more frequent refueling.
- Stalling Issues: Some 2019-2020 Ram 4500 trucks equipped with 6.7-liter Cummins engines have experienced stalling due to a failure of the high-pressure fuel pump. This issue has led to recalls and concerns about the reliability of these trucks.
- Brake Hose Rupture: A brake hose rupture can lead to a loss of braking ability, increasing the risk of a crash. This safety concern has been highlighted in recalls for the 2020 Ram 4500, emphasizing the importance of addressing this issue promptly to ensure vehicle safety.
- Engine Oil Issues: Low oil levels can damage the engine, potentially causing an oil leak or a punctured engine block, which in turn increases the risk of a fire. Maintaining proper oil levels and addressing any oil-related issues promptly is crucial for the safety and performance of the vehicle.
- Wheel Separation: Incorrect torque specifications in the owner's manual for flanged lug nuts can lead to over-tightening, potentially causing a broken wheel stud and wheel separation. This issue poses a significant safety risk and underscores the importance of following correct torque specifications for wheel components.
These common problems reported by owners of the 2020 Ram 4500 highlight the importance of regular maintenance, proper installation of aftermarket parts, and prompt attention to any warning lights or safety recalls to ensure the safety and reliability of the vehicle.
