P0E15 back after recall 03A: The pure contentious incompetence of Chrysler's software division is astounding!

@ChryslerCares It is time for the software division for all vehicle modules, including the Uconnect system with the Pacifica hybrids to be fired and replaced! How MANY more times will they get it wrong at this point? Reusing old code for the Recall 03A bringing back the BPCH bug? It is apparent the Chrysler software developers for this vehicle are lazy or simply do not care and take pride in their work! Who has to pay for the incompetence with their time? The people like me that have bought one of these. Are the owners that are out of warranty going to be screwed when this happens to them? Is this by design in an attempt to recover losses? Cha-Ching! $$$$

Three days of no issues after recall 03A and the first time the temp is below 40F, guess what? That's right, the problem with the BPCH software bug was put right back into the system. As opposed to last winter which was very cold because of this, my vehicle has been great this winter. Nice and toasty, until it got cold outside after the Recall 03A. Had no heat again.

Being this is now the third time this has happened my BPCH firmware is now perma-locked and is requiring a replacement on a PERFECTLY good BPCH that has had 0 issues since the last software update from TSB 08-052-22. Stellantis/Chrysler better get ready to be replacing over 67,000 BPCH very soon.

My two-year-old Pinnacle I have driven only when needed waiting for the loss of power issue to get ironed out, will still not be driven much due to the BPCH bug returning from the most recent recall software update. What is the point to have the BPCH replaced if it is going to be perma-locked every time the software bug throws the code more than 3 times? This is beyond stupid and unacceptable. P0E15 software bug should NOT be a thing at this point!

Just as rental companies will charge for loss of use due to damage or negligence I think it is time every owner of a Pacifica hybrid is compensated for the loss of use going forward due to negligence of bad software. I can guarantee you there will be no more software issues if this happens.

Ok well thanks for being the first penguin off the cliff! I guess I’ll wait for this one to get ironed out!
Just returned from my dealer this morning and they confirmed the BPCH is perma-locked just as BlueDriver indicated. They have ordered a new BPCH for replacement. They said 5 to 7 days out for the part to arrive. Then maybe a week after the arrival to schedule.

The hybrid mechanic came up front and talked with me and has the same thoughts as me, what good is it going to do to replace the part when the software is locking them? He told me he has replaced 11 of these in the last couple of months that did not have TSB 08-052-22 completed and one 2023 HV battery pack that was completely trashed with only 8,000 miles on it.

The funny thing is he knew what my next concern with replacing the BPCH was before I even asked. He came right out and said there is NO possible way to remove all the air from the system when replacing the BPCH and I might be coming back or getting towed back due to air in the system. He said Chrysler will not allow them to pull a vacuum on the system to remove all the air. He said he thinks pulling a vacuum could collapse the HV battery coolant chamber or pull on things inside the HV battery pack and ruin the HV battery. He said he has spent hours on these force-flushing coolant through them and some of them still come back with air issues.

Too late for current owners
But
Do we have percentages on these problems?
Reading the forum it seems as though 100% of pac hybrids are beta test disasters.
Is it really 1%? 10%? 50%

What is your definition of “beta test disaster”?
I wish that I could say that I understand everything that the OP has said but I can't.

I find that odd. I was just looking at the remedy instructions for the Z11 recall and it states:

"The preferred method to remove air and fill the cooling system is to perform the Coolant Air Evacuation procedure using the Mopar Essential Tools and Service Equipment Tool, UView Airlift Cooling System Refill 399-550000 or equivalent."

That UView Airlift kit can be found here:

UView Airlift kit

It is specifically a vacuum based system and Chrysler apparently has a procedure to use it to refill the coolant. If that kit isn't available there's also a procedure in the Z11 remedy to do it without vacuum assist. Here is that procedure:
  • Slowly add the engine coolant through the filler neck until the coolant level reaches the MAX level of the coolant reservoir.
  • Attach the SVT275 Cooling Pressure Tester (2), available from Mopar® Service Equipment, or an equivalent to the pressurized coolant bottle (1).
  • Operate tester pump to apply 100 kPa (15 psig) pressure to system. This should force coolant into any voids created by trapped air.
  • Release pump pressure and remove tester.
  • Add engine coolant until the coolant level again reaches the MAX
    level of the coolant reservoir.
  • Repeat this process until the coolant level stabilizes at the MAX level
    of the coolant reservoir.
So I'd maybe ask your dealer which procedure they are using and why. It seems like using vacuum is fine. And let's also not forget, the ECH and the battery are on completely different loops with no direct connection between them. So pulling vacuum on the ECH loop won't do anything to the battery loop. What you are being told doesn't really add up when compared to Chrysler procedures we know about.

Any vehicle 🚗 n its own merit was a beta tester . The Pacifica uses a unique powertrain compared to the wrangler , Cherokee . So any new vehicle introduced is a beta tester with a unique powertrain .
There should be a "Not Yet" option on the poll

This exact thing happened after I got the P0E15 problem "fixed"
6 days after getting the vehicle back from the dealership, I started getting the red wrench/lightning bolt and the "service high voltage system" error.

Just got the van back from the dealer yet again, and they said it was an issue with air in the system, "but couldn't find any coolant leaks. " Obviously they got air in the system while replacing the locked BPCH. So frustrating.

There are three different cooling systems not all of them can be vacuumed. This is stating to pressurize bottle 1, not vacuum. Vacuuming a coolant system is the fastest and easiest way to fill them without air. Pressurizing a system and then jolting it by releasing the pressure does not remove all the air. This system has so many valves, crossovers, exchangers, and electric pumps is one reason I will not own one of these past the warranty.

Well the tech said you can’t vacuum fill the battery system. That’s obviously wrong based on Chrysler’s own document. That kit is a vacuum system. And only if you don’t have it should you use the pressurize procedure.

Here’s the only other thing you could try. The ECH is on the same loop as the engine. And when in Hybrid mode, all heated coolant going to the 2 heater cores must pass through the ECH, which won’t be powered once the engine is up to temperature. So after you get this fixed I’d have the HV battery at <1%, and I’d set the temperature in the van to Max and go for a rip down the freeway, hoping to use the mechanical coolant pump to purge the system. Setting the heat to max should open a path through the ECH.
I'm in the not yet category. My vehicle is awaiting a new transmission. I live in socal, so it doesn't get colder than 40 degrees very often here, but it has quite a few times this year. I did have the 03A recall performed, but didn't get to drive it enough to find anything out.
What makes you tie the recurrence of the ECH issue with the 03A recall? As I've reported here previously, my '21 had TSB 08-052-22 completed in December and in late February the ECH failed again with permanently locked status. I have not yet had the 03A recall completed (was not even available when this occurred).
Same thing happened to mine after getting recall 03A completed. Waiting on part.

I think he's implying/thinking that they released the 03A recall update without the prior Z76 update software package included in it.
Well, my van is getting the recall update tomorrow. I’ll report back if I see any issues like this. I can say that I never had the BCPH bug but I did have the electric coolant heater problem about a year ago.

You're assuming they have a software division. It's probably subcontracted out to people that don't care.
Regardless software quality control and design for data degradation is non-existent.
