I can't hear you with all of that shouting! What are you asking??

I JUST PICK UP MY 2022 RAM LARAMIE GT I HAVE 38 MILES ON IT AND THE E-TORQUE DOES NOT SHUT DOWN AT ALL WEATHER I PUSH THE BOTTON OR NOT IT JUST KEEPS RUNNING ANY IDEAS?

There are several reasons why the engine won't Auto Start/Stop, the first one is pushing the button on the dash as it disables the system.
Other things that keep the Auto Start/Stop from shutting down the engine are HVAC demands, battery charge level, and engine/emissions temperatures to name a few. Drive a few thousand miles, if there's still a problem with it not shutting off take it to the dealership.

Etorque not working with ac on?

I picked up the limited longhorn yesterday and love it so far. The start stop function will not work with the ac on? is this normal? is there a certain temperature I need to set it at in order for it to kick in. I haven't driven the truck 100 miles yet and it's only averaging 13mpg. Does this...

I have towed a <5,000 lb. camper roughly 8,500 miles with my 2022 Laramie Sport 5.7 etorque 3.92.

I have had the check engine light/limp mode occur 5 times in that 8,500 mile period. The vast majority (if not all) instances occurred while in tow mode. My only question arises because I visually confirmed the tow mode with each instance except one.

Code said “Implausible data…”. Two dealers checked it out, said it looks like everything went back to normal after the events and nothing looks to be if concern.

The events all carried the same characteristics. After 400-500 mile long days, we pulled off to look for a spot to regroup. While driving at 30-40 mph, the CEL popped on. In nearly all cases, the limp mode took over. Shut down and restart cleared limp mode and CEL stayed for 4-5 start cycles.

I just had a recall flash for the hybrid control module which the dealer believes covers this issue. No scheduled tow trips until September.

2022 Laramie 5.7 eTorque 4WD, 6,000 miles. First opportunity to tow empty boat trailer (tandem axle, 1,400 lb) this weekend. Used Tow/Haul mode, after 5 miles, transmission locks in 3rd and won't shift up or down, even starting from a stop. Start/Stop Light and Check Engine Light. Tow/Haul mode dropped out. Strangely, Eco mode kept activating. Pulled over, turned off engine, waited a minute, restarted fine, no SSL, but CEL stayed lit. Normal operation for a few miles, then re-activated Tow/Haul mode and within a few miles, Wham, did it again. Seeing dealer tomorrow. Fingers crossed I don't get a runaround.

UPDATE: Took the truck into the dealer. Gave the service writer a copy of TSB 08-093-22, described my problem and he got the associated error code off the OBD. Software fix was installed. Tested with boat and trailer - ran fine. Bravo Zulu to Mpgrimm2 for posting and updating this thread.

We'll add this here and to the op....

Apparently I'm not the only one to have a 2022 eTorque truck stall while driving when the voltage drops below 12v after the HCP update in June 2022.

See here...

2022 Rebel GT Charging System

I have an issue for the second time in 2 months with the vehicle charging system. The battery voltage drops to 11.9V and the engine stalls at a stop. The engine RPM drops to 500; battery warning light is active in the dash. This is also an e-torque system which does not function for several days...

Hi All... I just picked up my 2022 5.7 e torque and with a 6000 lb camper she goes right into limp mode... stays in forth with the tow/haul on and 5th with it turned off..

I know there where a few trucks that had recalls for a firmware update for the computer for early 2022 with e-torque. I know mine had that issue as well, but after the update didn't happen again!

Well, It seems the updates may have worked....The dealer hooked up a 23 1500 to my trailer and it was better at shifting than my 22... But it is coming out of 4th sometimes.. better than it was. Chrysler is aware and it still working on it.....AND the transmission was much more active and smoother without the trailer..so the update did do something good.. haha

Forget to come back here on the limp mode issue. FW update fixed it all.
