Engine hesitating/stalling with no power

[HellaYella 21]

Our 2021 Jeep Wrangler Unlimited stalled today leaving a stop light. We had to coast to a parking lot since pushing on gas didn’t get a response. Any ideas what this could be?

Aux battery?

Can you provide more detail on what it did and what it has done since? Did ESS turn off the engine, and then it wouldn't restart?

Battery and/or fuse and/or ground-related problems can result in an amazing combinatiin of failures and idiot-lights.

Okay the engine light is on. Pull codes.

Engine never completely shut down until she turned it off . Restarted and no issues continuing to work. Its our first really cold morning with temps in 20s so don’t know if a cold engine would cause anything like this or not?

And what happened to your dash? Looks like the plastic has been sand-blasted or something!

Okay, that’s not a stall. Sounds like a problem with either voltage or the etc system. Still need to pull codes.

Gotcha. Be careful when you clean it. I use my compressor to gently blow off the worst of it, then a soft towel while avoiding the caustic window cleaners that are designed for glass.

I might have missed it, but . . . which engine?? ESS or eTorque??

Could be:

1. Loose fuses
2. Loose battery terminals
3. Bad auxiliary battery
4. Bad canbus connectors

One through three are easy fixes and nine times out of ten they solve the problem.

Good luck.
