Ram eTorque problems: Key Issues and Concerns
The Ram eTorque system was introduced to improve fuel efficiency and performance by integrating mild hybrid technology into the 1500 series. While innovative, this system has been linked to several issues that frustrate owners and raise questions about reliability. The eTorque replaces the traditional alternator with a belt-driven motor generator and a 48-volt battery system, enhancing low-end torque and energy regeneration during braking. However, despite its promises, multiple complaints about stalling, battery failures, and software glitches have surfaced.
One of the most alarming problems is sudden engine stalling, which can occur during low-speed driving or at red lights. Owners have also reported issues with the eTorque battery not charging properly, leading to loss of hybrid functions and performance. Additionally, software errors have caused dashboard malfunctions, inaccurate battery voltage readings, and automatic emergency braking activation, sometimes bringing the vehicle to an abrupt stop unexpectedly.
Common Problems with Ram eTorque Systems
The Ram eTorque system has introduced a range of issues that affect reliability and performance. Below are the most frequently reported problems, along with their symptoms and potential causes:
1. Sudden Engine Stalling
One of the most common and concerning problems with the eTorque system is sudden engine stalling. Owners have described scenarios where their vehicles unexpectedly shut off while idling at stoplights or during slow-speed driving. While the issue may sometimes allow a quick restart, it can be highly dangerous if the stall occurs in traffic or during maneuvering.
Potential Causes:
- Over-rich fuel mixtures in the engine, possibly due to miscalibrated software.
- Malfunctioning Powertrain Control Module (PCM), which requires reprogramming.
Reported Fixes:
Several affected models were recalled to update PCM calibration, which resolved stalling for many owners.
2. Battery and Charging Issues
The eTorque’s 48-volt battery system powers critical functions, including regenerative braking and start/stop operations. However, numerous owners have reported issues with the battery not charging properly, leading to hybrid system malfunctions, starting problems, and reduced performance. Some drivers noticed voltage readings dropping below optimal levels on the dashboard, signaling deeper electrical problems.
Potential Causes:
- Faulty motor-generator units (MGUs).
- Incorrect voltage readings caused by sensor errors or loose wiring.
Reported Fixes:
Replacing defective MGUs or re-securing wiring connections has resolved this issue for some owners. However, others have experienced recurring problems despite repairs.
3. Automatic Emergency Brake Activation
Rare but dangerous, automatic activation of the emergency brake has been reported in certain Ram eTorque models. This unexpected braking can cause the vehicle to come to an abrupt stop, increasing the risk of collisions.
Potential Causes:
- Sensor or software glitches triggering false emergency brake commands.
- Communication errors between the PCM and braking systems.
Reported Fixes:
Reflashing or updating the vehicle’s software often resolves this issue. However, it remains a serious concern for drivers who experience it.

4. Faulty Oil Pump Failures
The oil pump, critical for maintaining engine lubrication, has been flagged in several complaints. Owners reported ticking noises and decreased oil pressure, with some experiencing complete oil pump failure. Left unaddressed, this issue can result in severe engine damage, including a seized motor.
Potential Causes:
- Manufacturing defects in the oil pump.
- Debris or sludge buildup within the pump system.
Reported Fixes:
Immediate oil pump replacement and regular monitoring of oil pressure gauges are advised.
5. Software Glitches
The complexity of the eTorque system introduces dependency on advanced software, which has been a significant source of complaints. Common software-related issues include erratic dashboard displays, stalling, and hybrid system failures.
Potential Causes:
- Outdated software versions or corrupt firmware.
- Miscommunication between PCM and hybrid components.
Reported Fixes:
Dealerships often resolve these issues by installing the latest software updates and resetting the truck’s onboard systems.
