Engine shutting down while driving

[Snekpete]

I went to the dealership yesterday. The tech basically said "yeah, sometimes the trucks do that. We have no idea why and have no fix for it."

Does anyone have this TSB? The only one I've seen is tied to the auto start feature light not coming on, or something like that. I'm not sure that's the issue I'm having as I keep the auto start turned off on my truck because it is the dumbest feature that no one asked for.

Having a truck that randomly kills the engine then immediately engages the parking brake is probably the most dangerous issue I can think of, and no one at Ram seems to care.

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."
