Was Your Battery Replaced Under Recall?

Creating this thread to document the following:
• the process from the time you call the dealer for service;
• the outcome for each Z11 PacHY recall and whether your battery gets replaced or not.

For those who had a battery replaced, can you also list the dealership who worked on your vehicle?

EDIT: Added the Recall Service Procedures:

RCRIT-22V077-7110.pdf (nhtsa.gov)

I called my dealer and they hadn't yet heard that parts were available. They are looking into it and will call me back.

I dont have much hope for Chrysler engineers after seeing the attached PDF.

REALLY???? :rolleyes: :cautious: oy vey......
And where I live the number of days where the temperature outside will be warm enough to do this evaluation are running out.
What is a DTC?
Diagnostic Trouble Code. The codes that come up when you attach a scanner to a vehicle.
Dropped my car off this morning. I was told evaluation will be completed by this Monday. They said they had only tested one other hybrid so far and it tested ok. The Service instructions appear to be pretty precise as to sequence and time (step 43) alloted. I had asked if I could get copies of the VSR & ECU before and after reports which are to be provided to the STAR center for the HV Battery authorization. For me, I would like to know the criteria they’re using to evaluate the reports, I think having copies would be useful if you can get the master which they’re measured against. The service desk as expected said all I get is a doc saying Z11 recall service completed. I am going to pursue obtaining those reports because at least in my mind, it’s a paper trail, provided you can get the master, otherwise what do get after seven months, a piece of paper saying your battery checked out? Unless my thinking is wrong and unrealistic, I’d like something with more proof than a completed job order.
“If no DTCs are present, remove the wiTECH micro pod II device from the vehicle, return the vehicle to the customer. What is a DTC?

Good luck trying to get those reports. They could be interesting. Although they could also say absolutely nothing or be in a format that isn’t human readable. Sending those in could just be a fishing expedition to try to nail down the root cause, which they still don’t know. I don’t think those reports are what’s being used to determine if the battery is bad or not. It’s the test procedure as evaluated by the wiTech service computer that is making the decision.

I agree. I’d like more information on this “remedy”. Also, if this new software in the BPCM can prevent a fire by shutting things down before it happens, wouldn’t it be prudent to also apply it to other PacHys (2019-2022)?
Possibly if they think there is a risk to those model years. We don’t know what they are planning internally, so that could happen. They might want to let this new BPCM software exist out in the wild for a while to make sure it’s doing what they want it to, and isn’t triggering unnecessary battery swaps or missing actual fires. The lab and the real world never act the same. Prudence would dictate that they handle the customers actually under the recall as well before other model year owners are filling up service slots. They could eventually roll this out across the model years as a service campaign or a RSU like they now have for the ECH fix. But I would expect that wouldn’t happen for a while.
So this in my view is not as good a solution as a better thermal dissipation design and battery cell quality control.
There’s nothing to say that either of these things would help. Thermal events are going to happen with batteries. Just like ICE vehicles sometimes start on fire. The idea is to minimize those events as much as possible. I don’t think we have any evidence that a better thermal design would help in this scenario. The thermal design of this battery is very similar to other batteries. There’s 2 plates below the battery modules that have coolant running through them, which is basically how all pouch battery systems are controlled. As for cell quality control, again you’re always going to have some bad apples. We don’t know if these pouch cells have the same defects as the Bolt batteries did. Again we don’t know if it’s the cells themselves that are starting the whole event or not. The cells could be innocent, but something is heating them up enough that a thermal event is started and then it’s game over. No cooling system would be capable of handling something like that. Unless they actually find the root cause it’s going to be a bit of a mystery.

Which is what constitutes a bug in thermal design.
Another component starting on fire and eventually igniting the battery is not a bug in the thermal design.
I took my 2021 in for an oil change yesterday (it'd been a year) and to knock out the recall for the 2nd row seat latches (mine wasn't affected though--but to check it off).....little did I know that I think I was eligible for this recall until the guy told me.
I think it's this software flash recall anyways (the paperwork is at home).......but I never had an issues and they flashed the car yesterday and I need to pick it up today.
Had you had the ECH update done to your van? There is now a service campaign (not a recall) for 2021 models to update the HCP, AHCP, and the PCM to prevent the problem with the ECH getting locked out. That’s probably what they did. It has nothing to do with the Z11 battery recall.

The recall only takes 2-3 hours of active “tech work”. But between charging and resting the total procedure takes 1.5-2 days.
This is the first we have heard of anything failing and then being retested.

Can you show the the work description? @ChryslerCares is this protocol for a failed test?
Its also possible it failed due to not following the test procedure properly. It's not clear if it's the battery that failed a correctly run test, or if an incorrect procedure caused a failure in the test itself.
Sounds normal to me. After constant monitoring over a few weeks I quickly concluded the battery monitor and mileage estimator are only loosely related and do not correlate well.

Just watch the battery monitor and you'll get a much better feel for the real mileage than the computers own estimate. At this point I pretty much consider it a ballpark and almost ignore it in favor of the battery percentage.
This is correct. It’s also using recent driving style and outside temperature to guess that number. But if your garage is warmer than outside it’ll be wrong. If you drive different it’ll be wrong. It’s also fall and getting colder and if you are using electric heat it’ll drain faster. That range number is a very very mushy number.
Left my van for the recall fix yesterday. Got call from dealership to pick up this morning. Upon arrival, found the battery is at 0% charge level. Logically the recall procedure was not completed. Turns out the tech did the service stopped after flashing the new battery software to the vehicle and though that was all needed.

Asked them to perform the test procedure again properly.
Brutal. Report the dealer to Chrysler. Report them to the provincial dealers association. Report them to Transport Canada. It is unbelievable that a tech couldn’t follow a recall procedure designed to fix an unattended fire problem! Chrysler needs to know this is happening. It’s just callous disregard for the safety of others.

What about for Canadian owners?
And WHY would anyone permit a flash that can leave your car (possibly) in the middle of traffic if at any time, the car decides it has a problem? Great.
Modern cars are full of events that can cause the propulsion to be shut down or be limited. Usually they are trying to prevent or reduce damage that may then have to be fixed under warranty, or prevent a situation that could cause a lockup of the driveline (like with a transmission fault) with the vehicle at speed. An unexpected shutdown with a coast is more safe than a locked up driveline. That’s really not particularly unusual. In this case I highly doubt it’s a full unexpected propulsion shutdown. The Pacifica (ICE and Hybrid) already has the programming to request on the cluster for the driver to pull over, shift to park, and shut the vehicle down. I would bet that’s what it will do in the field should the new software detect a fault with the battery that may indicate a fire.
I’m wondering if this recall entails charging them and listening,
It does not.
When plugged in, ours made very loud sound like a fan was trying desperately to cool it while charging (car off).
This is normal when you are charging in high ambient temperatures. What you are hearing is the electric air conditioning running to keep the battery cool when charging in high ambient temperatures.

BTW we’ve had Chevy Volts for many years and I guess they don’t have this loud fan thing - never heard a peep from the Volts. Just smooth charging and driving, as advertised.
The Pacifica does get somewhat noisy when it does this. They seem to prefer to run the radiator fan and electric A/C at high output for a short period of time rather than run them slowly over a longer period of time. It will also run just the fan itself if the power electronics loop is getting too warm during charging.

I got my recall done Thursday. Supposed to take 2 days but took 3 hours. I knew the battery needed to be discharged so I dropped it off with 10%. Got it back with 10%. Pretty sure no charging or discharging took place. All they did was a software update. I don't think they have a charger or the right tools. I will check charge rate tonight.
This makes me very unsure that the recall was done correctly. Reading this, it certainly wasn't:
Not sure what to do at this point. A fire risk needs to be dealt with thoroughly.
Run don't walk.

I do understand that the 100% charge range is an estimate. I have had a couple of pure electric vehicles and unlike those, I won't get stuck if I run out of juice in my Pacifica. But it is now estimating the range for my vehicle differently. Why? Is it keeping a larger amount of battery capacity in reserve for Hybrid operation when it reaches the 0% indication? Or have I suddenly lost some 5-10% battery capacity? Not sure why I should ignore that, and why that can't be answered by Chrysler.

The service seems to be a two-part process, the software flash of the BPCM, followed by the Integrity procedure, and possibly the battery replacement procedure.

What are your thoughts on how the vehicle operation may be restricted in the event of a significant battery problem? Any knowledge you can pass on?
I’m guessing you’re in the Northern Hemisphere and that your weather has probably gotten colder recently? That range estimate is also responsive to the outside air temperature sensed by the vehicle.
I'm in San Diego, and the average temp for the month of October was about 70 with little variability. I have had the car for almost 4 years, and have only seen 31 or occasionally 32 on my 100% charge range since I bought it. Now consistently 29 miles, and only since the Z11 update. I imagine the temp. variation up north (Canada?) would cause issues.
Ugh I would give a kidney to live in San Diego. I’m currently looking out my window at snow and it’s currently -7C.

After fighting with my Dealer that this isn't just an update I drop off my car yesterday. They kept saying it will only take 45 min. I even asked him to read the recall notice and when it said 1.5 to 2 days. He said that is just an over estimate if you need a new battery. They asked me to bring the instructions to prove they need to do more. I brought the instructions and showed the the 60% charge for the update and then 100% charge for the test. The hybrid tech said he know it take 2 days. I was relieved that is seamed they listen and was going to do it right.

Unfortunately when I went to get the car today they said there was no codes so they only did the first part and updated it. They did not need to do the 100 charge per there instructions. I asked to see what they have and they said they can't show me it is company policy. I asked about my instructions that I left a copy for them. They stated it was not correct and they have to follow the one they have. They wash and Vacuum it. But when I got in it. It was only 14% charge, and not 1 mile added to the odometer. I asked again for the manager and they said it was closing time and I will have to come back tomorrow if I wanted to speak with the manager. I am disappointed and am not sure if I should trust the recall was done. I will wait a few days and see if it shows completed on the recall website.

Ken Ganley in Bedford OH is the dealership FYI.
It definitely will show as complete. But it obviously wasn’t done correctly. I would call Chrysler and report your experience. It might also be an interesting experience to call your insurance company and ask them about a recall due to a possible fire that you know was done incorrectly. And if you’d be covered if it then started on fire. I would also call the dealers association for your area.

New NHTSA document out about the recall. Sounds like Chrysler is reading the riot act to its dealers who are not doing the recall correctly. Basically saying that Chrysler can tell if you didn't do it correctly, and you need to get the customers back and do it correctly or your dealership could be in peril. Here is the link.
