Understanding Ram eTorque Problems and Ram Hybrid Issues
Many drivers research Ram eTorque problems and related Ram hybrid issues to understand battery system failures, inconsistent stop/start behavior and sudden loss of power.
The eTorque system relies on a 48 volt battery pack, a belt driven motor generator and multiple control modules. When any of these components malfunction, the truck may display warnings, disable stop/start or experience reduced performance.
Common Ram eTorque Problems Including Battery Pack Faults and Stop/Start Failures
One of the most frequently reported issues involves the 48 volt battery pack. Owners describe warning messages such as “Stop/Start Unavailable” or “eTorque System Service Required.” In some cases, the truck shuts off stop/start functionality for the remainder of the drive.
Forum discussions often show frustrated owners sharing similar experiences. One driver described it this way: “My eTorque battery keeps throwing errors every few weeks. Dealer says it’s fine, but the truck definitely doesn’t feel right when it happens.” Another owner wrote, “The truck hesitates when taking off from a stop, like the hybrid system can’t decide what to do. It’s getting worse with mileage.”
These symptoms commonly stem from voltage irregularities, cooling fan malfunctions for the eTorque battery pack, internal module failures or degraded cells within the 48 volt unit.
Approximate Cost to Diagnose or Repair
| Service | Estimated Cost |
|---|---|
| Hybrid System Diagnostic | $150-250 |
| 48 Volt Battery Replacement | $1,200-2,200 |
| Motor Generator Unit Replacement | $1,000-1,900 |
| Cooling Fan Replacement | $300-700 |
| Module or Sensor Repair | $150-450 |
Power Loss and Sudden Performance Drop
Some Ram 1500 eTorque owners report sudden power loss, especially when merging or climbing hills. The truck may briefly cut power or hesitate before accelerating.
One owner summarized the behavior online: “It feels like the truck lets off the gas for half a second even though my foot hasn’t moved.” Another wrote, “The power loss is random but scary. It usually happens when the stop/start system is acting up.”
These events are often triggered by overheating in the eTorque battery, failing MGUs or software logic faults that disable hybrid assist.
TSBs and Recalls Related to Ram Hybrid Issues
Stellantis has issued technical service bulletins addressing certain eTorque concerns, including:
- Software updates for stop/start inconsistencies
- Diagnostics for faulty 48 volt batteries
- Procedures for cooling fan malfunctions in hybrid battery systems
While no major nationwide recalls have targeted the eTorque system as a whole, individual component recalls may apply depending on build dates and equipment.
Owners experiencing repeated eTorque messages are often advised to request a hybrid system reflash, as multiple TSBs have included updated calibration files.
Early Warning Signs of Ram eTorque Problems
eTorque failures often begin subtly. Early indicators include intermittent stop/start disable messages, brief dimming of interior lights, inconsistent throttle response from a stop, warning lights that appear only in hot weather, and the truck idling rough before hybrid assist activates.
Catching these symptoms early prevents sudden power loss or complete eTorque shutdown.
Preventing Ram Hybrid Issues Through Proper Maintenance
Maintaining system voltage is critical. Owners should replace the main 12 volt battery at the first sign of weakening, as low voltage significantly affects hybrid components.
Regular inspections of cooling ducts, software updates and belt condition for the motor generator also help preserve long term reliability. Avoiding excessive idling in extreme heat can also reduce thermal strain on the 48 volt pack.
Should You Be Concerned About 2020-2024 Ram 1500 eTorque Reliability
While many trucks operate without major failures, repeated hybrid system warnings or loss of stop/start functionality should be taken seriously. eTorque repairs are more expensive than conventional powertrain fixes, and issues tend to worsen once battery packs or MGUs begin to degrade.
Prompt diagnosis helps prevent system shutdowns and more significant repairs.
FAQs About Ram eTorque Problems and Ram Hybrid Issues
Why does my Ram 1500 display “Stop/Start Unavailable”
This message often appears when the 12 volt or 48 volt battery voltage drops, the hybrid system overheats or control modules detect inconsistencies.
Are 48 volt battery failures common
Battery pack faults are among the more frequently reported eTorque issues, especially as trucks reach higher mileage.
Why does my Ram lose power when accelerating
Power loss may occur when the hybrid assist system shuts down temporarily due to overheating, low voltage or MGU faults.
Does the eTorque system have any recalls
While no large scale recall covers the full system, several TSBs address software updates and component diagnostics.
Can maintenance reduce eTorque problems
Yes. Maintaining battery health, installing software updates and ensuring system cooling works properly all reduce hybrid failures.
