Okay, we're a pretty smart group here but we're not clairvoyant. Most of the TSBs were for earlier years, 2019-2022. We need to know the model and year. In the safety settings turn off the Auto Engage on the parking brake. That should also prevent the automatic shift to park but I am not sure of that.

Sorry. 2021 Ram 1500 5.7 Hemi with etorque.
Is this the parking brake setting you're talking about? If so, it was turned off when the truck killed this past Friday and parking brake still engaged.
Yes, that looks like the Auto Park Brake setting, so when you put the truck in Park the parking brake Should Not go on.
The 21 and 22s had a TSB to flash the PCM to address the low speed stall issue. I know I had mine flashed. I don't recall the TSB but if you do a search of TSBs for your model and year you should be able to find it. I don't believe that it will fix this problem however. AFAIK there is no known fix for this problem.
It is my opinion that the problem lies in the transmission or the TCM, or both. I have personally experienced this in a rented Jeep Wrangler with a completely different Hybrid motor but the same 8 speed transmission. If my truck does this I will be very tempted to track it down once and for all. Maybe start a Go Fund Me to buy a new trans.

There was a recall - 37A - that was supposedly tied to this issue, and required flashing the PCM. I had the recall serviced last year.
The truck had previously died on me twice before the recall was fixed. I haven't had the issue happen again until this past Friday.
When I went to the dealership yesterday, the tech told me "We can make an appointment to drop the truck off for us to check, but you'll be wasting your time, because they won't find anything wrong with the truck."
Have had this EXACT thing happen twice now, 3 months apart. 2023 Rebel GT 5.7 Etorque with 30,000 kms.

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.

I have a 2021 ram etorque, had it in for a few recalls, just putting it in the garage would shut off and engage the ebrake, release the brake and drove it in. Yesterday we went on a trip pulling a enclosed trailer, about 2hrs into the trip, engine shuts off at 70mph
Luckily got it off the road, unlocked the brake tried to start it, it would only crank, tried it numerous times, 93 degrees with no air, finally tow truck arrived, towed it to dealer, soonest they can get to it was Friday, could not get a rental car, luckily Toyota had a few, so I left home in a ram, returned in a Toyota. This truck only has 19,000 miles on it. Been watching this forum and can’t believe all the trucks having this issue, it don’t seem like ram is gonna fix this issue. Hopefully Friday the dealership will find the problem, but not getting my hopes up after reading all these posts.
Stalling at 70mph is a completely separate issue from the low-speed stall and should be able to be fixed. The Star Connector should be the first point of concern.
