Apologies if this is well covered already. Our 2021 Pacifica Hybrid suddenly stopped running on the highway, lost all power, and quickly decelerated. We were able to pull over to the side of the highway and tried a few conservative things (turning it off, letting it rest, opening and closing the doors, etc). But each time we started it, it would only allow us to go about 3 km/hr and would shake a bit while doing that. Going in reverse was no problem. We had it towed to our dealer and it will be seen sometime in the next 2-3 weeks!

We never saw any warning lights, indicators, or turtles, etc at all during the whole process! Any insights as to what this could be?
Thank you!

Without DTCs, it is a guessing game.

Possible causes are:
Your 12-volt battery may have failed, causing malfunctions due to low voltage.

Bad ground/s.

Failed PIM but should have gotten the red wrench and service hybrid systems warning in the instrument cluster.

Failed transmission, but I have not heard of them shaking. If the transmission fails, you typically receive the 'vehicle will shut down soon' message in the instrument cluster.

This is the second time this van will be stuck on the lot for weeks (the first was with the battery coolant heater failure).
