Just call Chrysler Customer Service, calmly and kindly explain the issue and severity, and ask them to escalate this to the regional manager for your area. No need to wait for ChryslerCares or anyone else, you can do this yourself.

Cool thanks. I called before when my car first broke down but was unable to get the case escalated. I’ll try again now that the vehicle has broken down twice.

By the way, I still need to get my car to a dealer. Do you guys know if I should bring it back to the dealer where I leased the vehicle or a dealer closer by where I'm located?
Thanks again.
Thanks again.

I called Chrysler Customer Care as ya'll suggested. My case is assigned to a retention specialist given that the essentially the same issue surfaced twice.
I also brought my vehicle to be serviced at a nearby dealership, but not the same dealership where I leased my van from.
I had let my specialist know which dealer is servicing the vehicle, and my specialist said she'd contact the dealer once I drop off my car. A few days later, the dealership calls to tell me that they ran a system diagnosis on my van and everything checked out... even though they found the same DTC codes as I did... and they wanted me to pick up my vehicle. I felt it was kind of irresponsible when my service rep said "just bring it in when it breaks down again".
I called my retention specialist at CCC and let her know of the situation. It turned out that she didn't get a chance to reach out to the dealer the entire time but promptly escalated the issue. With that said, I want to stress that my experience with CCC is generally positive: folks generally want to help but they will take a few days to respond. I do get the sense that they're overwhelmed though. A few days since that conversation, Chrysler engineers have been requesting information from the dealer.
Today, I got a call from the dealer indicating that my vehicle indeed requires some fixing, and that they ordered this 68396626AA part from Chrysler. Per the Mopar website, the description for this part is 62-way wiring. Not sure what that is, but one can only guess this is wiring needed for the hybrid system to run properly. So the car will be in the shop until mid-next week at the earliest.
I'll continue to update as I have more to share.
Thanks!

So there was a fault and the dealer didn't want to do anything until Chrysler got involved? Shame on them for that. But i'm glad that Chrysler Customer Care helped you out here. I agree they seem helpful and really want to be a mediator between you and the dealer "service" department. I also had a bad wiring harness in my first 2 weeks of ownership, so maybe they got a bad batch or something from their supplier.
Report this to NHTSA. Now.
This smells like a potential "we goofed up a wiring harness" situation. Isolated? Only NHTSA collected reports will tell the tale.

Reported just now.
Also I called the dealer again just now and got a hold of the service manager. He indicated that the wiring to the PDC (power distribution center) connectors "didn't have enough tension" to properly distribute power across the vehicle's systems. If I heard that right, it sounds like when the vehicle was being put together, these connectors just weren't put in place properly or tightened enough (I'm probably generalizing/over-simplifying) which for some reason results in a whole new part being required to fix the issue.
I also feel 1) that this is not the issue and 2) there are other issues lurking in the background waiting to be discovered... oh well, until the next break-down happens I guess.

Oh and the target date to have the vehicle back is next Thursday, meaning that the vehicle will have been in the shop for 17 calendar days. Plus one day as related to the first incident. So 18 days total in the shop.
I think CA lemon law requires 30 days in the shop. So I'm more than half way there if things go down that route. I certainly hope not.

Gang - just wanted to provide an update on my saga. Just to recap, I brought my vehicle to a nearby dealership after running into issues with the hybrid system for the second time. At the same time I contacted Chrysler's customer care to raise the issue, and a case was created. Dealer couldn't figure out the issue and tried to send me on my way, but Chrysler had its engineers look into the vehicles and somehow determined that there were several PDC connections that had loose terminals. Dealership ordered a new 62 way wiring, installed it per Chrysler's instructions, updated software for the HCP, AHCP and PCM and test drove the vehicle for ~30 miles with no issues.
I picked up the vehicle today, and wanted to share with ya'll the service invoice.
A few things about the invoice that stood out to me:
One last thing, I just found my vehicle's wiring issue documented on the NHTSA website. I've attached the PDF below as well.
I truly hope this is the end of major / safety related issues with the van. And I hope my experience will help at least one of you. I'll keep updating this thread as I drive my vehicle over the next few weeks, or if I have anything further to share with ya'll.

I picked up the vehicle today, and wanted to share with ya'll the service invoice.
A few things about the invoice that stood out to me:
- My OBDII reader picked up two error codes but the vehicle actually threw five DTC codes
- U151A-87 Hybrid Control Processor Secret Code-Missing Message
- U115B-00 Lost Communication with Right Hands Free Sliding Door Module
- U115A-00 Lost Communication with Left Hands Free Sliding Door Module
- U114D-00 Lost Communication with Hands Free Liftgate Module
- P0513-00 Invalid SKIM Key
- These error codes aren't the same ones that my OBDII reader picked up previously (U0100, U1818)
- All these codes - ones that the dealer picked up and ones that my OBDII reader picked up - showed up when my car wouldn't start during my first incident
- As a result, one can deduce that the repairs done as related to my first incident (all they did was a BPCM firmware flash, really) was ineffective for the most part in resolving the van's issue
- Chrysler Customer Care opened a STAR (Service Technical Assistance Resource) case as related to the matter when the dealer couldn't diagnose the issue and tried to send me on my way with a vehicle with known issues. By the way, does anyone know if there's any way to look up a specific STAR Case? I'm trying to find mine
- Lesson learned: Can't completely trust the dealership. If you have a known issue that has repeatedly manifested itself, don't believe the dealer when they say there's nothing wrong and that you should be ok irrespective of how friendly or cordial your service rep is. They're motivated to move issues onto someone else's plate. Remember: Your safety is all that matters
- By the way, my friendly service rep was surprised to hear from FCA. His words "They (FCA) somehow found out that your car is here and that we asked you to pick up your car"
- My vehicle's issues (at least some of them) may not be uncommon given that there's a TSB file on it (TSB 08-091-21). I'm unable to find this online. Can someone help me look?
- There are a few updates that we all should make sure we get:
- HCP - 684991122AE
- PCM - 05185116AH
- BPCM - 05193183AE

By the way, the NHTSA PDF is dated 2/12/21, a month prior to my first incident... which implies that the service department where I took my car for repairs after the first incident just didn't check this resource at all. That's pretty lame of them if true. I'm starting to doubt the after-sales support of the Chrysler brand.
If you ever run into issues, make sure to 1) document your DTC codes if you're able and 2) check if your issues have been documented on the NHTSA website... because again you can never trust that your service department will be diligent. If you don't have an OBDII reader, I strongly recommend purchasing one. Showing up at the dealership with your DTC codes in hand should help avoid the "there's nothing wrong with your vehicle" run-around that folks may get.
Nothing out of the ordinary. I wish there had been something specific I could attribute the CEL to!
Writing this from my local Chrysler dealer service bay…
That’s the same TSB my service tech referenced when I brought my car in for a CEL. After claiming they fixed the problem, the CEL came back less than 24 hours later. Brought it back to the dealer, who said they’d order a replacement part (coolant valve I think) that should fix my problem.
I haven’t had the issue you describe, but I agree that I’m suspicious of what the dealer service reps say!

Cool thank you. I'm mostly curious about the contents of that TSB 08-091-21. I'm not sure which issue(s) that TSB addresses.
I tried to search for it online and couldn’t find anything…
Did someone say wiring issues?
Hybrid System Failure on 2021?
Curious if anyone else has had this happen yet? We had 2000 miles on the new Sienna when it started saying “Hybrid System Failure, Contact Dealer”. We took it in and they said the main hybrid wiring harness has a faulty connector. The problem is, they don’t have a part to fix it. It’s been...
