Stuck in 1 st gear 2019 Ram 1500 4x4

[Jako]

All clear after new battery and drive cycles, reported to NTSB. If you had cold or weak battery in snow…people could die. You could try to pull out in traffic and realize too late you got only 1st? Software sucks. I like it when it’s working but engineering is about reliability, failure modes and safe states should there be a failure. Low battery is the most common state. Why would you limp a car if the stability control is not talking? Just revert to old school human control. This is as dumb as the leaky rear window dripping on RF hub, it fails and you have no way to start truck, even with the manual key that let you in the door. Wake up Ram, people use these trucks in the extreme, design them for that. Take your controls engineer to snowy backroad, disable the RF hub, give them a new battery, let battery die and then leave them there. If they don’t come to work the next morning, hire another. Repeat until one shows up, then you have a real engineer.

Had it happen, one hell of a learning curve/experience. I only drive the Ram once a week or so these days. So now it is on a battery tender, keep an eye on the battery voltage, along with keeping a jump start in the Ram and I am well versed in parasitic drains and batteries for the Ram.

I can confirm all my battery issues I had with my truck was 100% due to the Pedal Commander. After removing that I have not had any issues with my battery.

Had the rpms, speedo and gear shifter do some funky things also. It didn't come out of first but after sitting it came back.. There is a thread on this.

Info sent to "Ram Cares"
As far as the "not coming out of first gear" a member on the 5th gen forum had a similar problem (POST 335659) and was resolved with "the tech found a split PCM connector pin". This by far is my biggest concern and I am not sure how readily it can be diagnosed and resolved. Other people have complained on "carcomplaints" with not coming out of first gear. Intermittent electrical issues are probably the hardest to diagnose. We have had some heavy rain in the previous days and I do not know if this correlates to the issue. Driving habits and use has not changed in the two years of ownership, no off roading, towing or heavy loads. For the most part it is a "pleasure vehicle".

In addition to not coming out of first gear the display stated:
1. Service Electronic Stability Control
2. Service Trailer Brake System
3. Park Sense Rear Braking Assist Off
4. Service light was on (not sure if engine or traction control)

I went out an hour or so later and the situation resolved itself.

Again the battery resolved the problem.

I am seeing the exact same symptoms on my 2019 bighorn. I will try replacing the battery and will report back here soon, but I have to ask... why can't the truck detect the nature of this apparently simple problem and provide the driver with a clear an appropriate message along the lines: "Yo! Dingus! replace your battery! it's boned!" or similar, instead of "Service Electronic Stability System" which seems unrelated and misleading.
