New 4xe complete electrical shutdown!

[Wrangler21]

I have seen the issue first hand with a friend. We needed to really push the fuses down 1 by 1 with a torque bit or something tougher than our fingers to get them seated (Especially the smaller ones). Seems to have fixed some of the gremlins.

I think that is what the local dealership ended up doing to fix it. They went through and adjusted fuses.

Has anyone/any dealer found a solution to this problem? (Mysterious drain on 12 volt system to 3.5 +/- volts resulting in complete shutdown of the entire vehicle) My 2021 Wrangler Rubicon 4xe is at the dealership for the 3rd time with this issue.

It is clearly not a singular event as all of the forums have threads with multiple responders with the same issue. My dealer says they are unable to replicate. Very frustrating when you are stranded with a dead Jeep with the same failure over and over. Trust me, it replicates.

I am really surprised FCA hasn't figured this one out yet. If anyone from FCA is reading this, ,you have a problem that needs an electrical engineer's attention.

After 2 weeks at the dealer, I picked up the Jeep today. Unable to replicate.....

Here is what we know:
The problem is not the 12 volt battery.
It does not matter what the ambient air temperature is, failure occurs at hot and cold temperatures.
It does not matter the charge on the hybrid battery, failure occurs at 0% or 100%.

The current plan is to wait for it to occur again and have the vehicle towed to the dealership with the condition of failure intact.

The interim solution is to carry a jumper box with you if a tow is not safe or unavailable. Did anyone else see the jumper box option on their 4xe order form? Just being cynical...
