Common Issues with the 2020 Ram 1500's eTorque Mild Hybrid System

The 2020 Ram 1500’s eTorque mild hybrid system has been reported to have several common issues. Here is a detailed look at some of these issues and potential solutions:

1. Battery-related Problems

A frequent problem with the eTorque system is battery-related issues. The system uses a 48-volt battery to provide additional torque and to power various components. Commonly reported problems include:

• Battery draining quickly
• Battery not holding a charge
• Battery overheating

Solution: Diagnosing battery issues often starts with checking the battery’s health and charge status using a dedicated diagnostic tool. Replacing the battery may be necessary if it fails to hold a charge. Regular maintenance and ensuring that the charging system is functioning correctly can help prevent further battery issues.

2. Faulty Electrical Components

The eTorque system is heavily reliant on various electrical components and sensors. Problems with these components can lead to the system not functioning properly. Symptoms include warning lights on the dashboard and irregular or non-functional hybrid assist.

Solution: A thorough electrical diagnostic should be conducted to identify any malfunctioning sensors or electrical components. Replacing faulty parts and ensuring good electrical connections are vital steps. Regular inspections of the wiring harness and connections can also help avoid electrical issues.

3. Software Glitches

Software issues within the eTorque system’s control module are also common. These glitches can cause erratic system behavior, including failure to engage the hybrid assist or unexpected warning messages.

Solution: Updating the software of the vehicle’s electronic control module (ECM) to the latest version can resolve many of these issues. In some cases, reprogramming or resetting the system can clear minor software glitches. It is advisable to have these updates performed by a qualified technician at a dealership.

4. Cooling System Issues

Proper cooling of the eTorque system is crucial for its optimal performance. Overheating can lead to system failures and reduce the lifespan of various components.

Solution: Regularly checking and maintaining the cooling system, including coolant levels and the condition of hoses and radiators, is essential. Ensure that the hybrid cooling system is functioning properly and that there are no leaks or blockages. Professional servicing can help detect and resolve any cooling-related problems.

5. Belt and Pulley Issues

The eTorque system uses a belt to connect the motor generator unit to the engine. Over time, the belt and pulleys can wear out or become misaligned, leading to performance issues.

Solution: Regular inspection and maintenance of the belt and pulley system are important to prevent wear and ensure proper alignment. Replacing worn-out belts and pulleys can prevent more significant issues and maintain system efficiency.

In conclusion, while the 2020 Ram 1500’s eTorque mild hybrid system offers enhanced performance and efficiency, it is not without its issues. Regular maintenance and timely intervention can resolve most common problems, ensuring the system remains reliable and functional. Consulting with a certified Ram technician for any persistent issues is always recommended.
