Been having issues with the truck since 8,000 miles. Now almost 50k. The dealer replaced MGU (eTorque) at 16,000.
Truck is 2023 1500 3.6 v6 with etorque (MGU).
Truck shuts off while at low speeds, almost like motor hesitates and then dies, sometimes when gently pressing accelerator/gas pedal.
Been to the dealer now about 10x, they reprogrammed truck, they checked electrical systems, and they replaced the MGU unit last year as they could not for sure figure out what is going on. Truck seemed to work okay. Service manager (SM) requested to bring it in immediately if it happens again, so this time I did when it died.
What happens when it dies/stalls... Truck shuts off. Restart and get low battery warning. If you drive without shutting and restarting the 12v battery begins to drain and will get below 10volts, then the dash lights go off, the truck will eventually begin to idle at 2k RPM, exhaust smells like rotten eggs (according to me and dealer mechanic), and this time it started overheating when I took it to the dealer and coolant fluid boils out of the overflow. That got the service managers excited as they saw this all happen in the service bay.
HOWEVER, if you just shut down and restart after initial restart, the truck works fine.
Truck is at dealer since this just happened and they ran tests while it was still running before it died ( it pulled 25 something error codes, I'll share shortly).
Today they ran more test and it came back normal with no errors. SM said they would replace MGU again to see if that helps as mechanic said there have been some issues with his past experience.
I requested they check lithium battery - no report yet.
Beginning to wonder if it is fuel related, like an injector.
UPDATE: Dealer said after restart the codes were cleared and truck ran fine. Mechanic suggested to replace MGU so they did. This is the 3rd MGU (eTorque) for this 2023 1500 3.6 v6 with etorque.
I wonder if it is caused by the running too rich that effected other model years (2021), however they state is only the 5.7 eTorque model.
Some 2021 Ram 1500 eTorque models may stall while driving, leading the automaker to launch a new recall campaign to fix the issue — here are the details.
