Here is the post where the owner of a 2018 PacHy said they had an issue with the PIM:
That might be the PIM, or the coolant heater or something else. We only know the code which can indicate a lot of things.

Aside from that I believe there has been one confirmed PIM problem in the Facebook group with a 2018, and possibly one failure in a 2017 after the recall was done? Maybe?

It appears the recall has been effective at solving the PIM shutdown issue. There could still be an occasional manufacturing or assembly defect involving the PIM.

I'm not referring to the OP of that thread, there was another member who posted later in that thread they had a PIM issue.

This must be your first foray into recalls. Recalls take time and they notify you via mail. I got a recall notice for an airbag months after hearing about it in the news. Let the system work. Or you could go crazy and start another petition or call news outlets hysterically claiming how you've been wronged.
No - not my first by a long shot. And the van has had two performed already (T23 & T54 -- one a NHTSA and the other a "Customer Satisfaction" campaign.)

I am not pushing for anything, but since expectations and impatience are already at a high pitch on these multiple stall issue threads, information is the only thing that will bring about some semblance of patience.

As I said on another thread, it is not crystal clear that Chrysler has the solution yet or started to distribute it to the dealers, and that ambiguity will only inflame some. There is a history of automakers saying they are going to fix the problem without a timeframe, but at least they are upfront about it. One of the recent examples -- Honda recalled 900,000 Odesseys for a 2nd row seat that could move under braking, but was still working on a solution.

The dealer just got information today about the recall, but hasn't received the software. Since it will be a few weeks for a recall appointment, I made an appointment for a convenient day in March hoping that they will have the software by then. (My van has 18,000 miles and hasn't stalled.)

Recall for my van on mopar.com and NHSTA sites.

NHSTA info:
1Recalls
associated with this VIN
Jan 11,2018
Manufacturer Recall NumberU01
NHTSA Recall Number18V-TBD
Recall Status Recall Incomplete, remedy not yet available
Summary
Vehicles may experience an engine stall without prior warning, without lighting a Malfunction Indicator Lamp (MIL) and without setting any Diagnostic Trouble Code (DTC). In the majority of cases the stalling occurs at low speed, while decelerating, while at idle or while negotiating a turn.

Safety Risk
Engine stalling results in a loss of motive power, which can cause vehicle crash without prior warning.

Remedy
The PCM must be reprogrammed with new software.

Manufacturer's Notes
For more information, visit recalls.mopar.com or call 1-800-853-1403. Please have your VIN ready when calling.

Just MY opinion, personally I don't think they have a clue what is causing this. They are still not giving us details. I believe even after this update, this will continue.
I think these systems on these new cars are so complicated, even the OEM doesn't fully understand them.

Again only MY opinion.

Back in August, someone posted a similar opinion the main shutdown thread. The conceptual problem some will have is apparently it is a software fix, just like the patches you get on your computers and cell phones to correct security issues. There is no part to yank out and replace. And unfortunately the follow up is "negative" proof -- i.e. shutdowns will not happen.

And what will cloud THAT issue is that there will be stalls and failures, but (hopefully) not this mode. This fix appears to address ONE issue (albeit a big one) Engine stalls without warning, and after stopping, the car starts and runs normally and there are no codes. But if you looks at these threads, you see owners complaining about Hybrid issues, cars acting up, then stalling and refusing to move, etc. NOT THE PROBLEM THIS RECALL ADDRESSES.

So yes, we will have to take it on fingers crossed faith that this software fix will correct this one issue. Only time will tell, and you can bet the people on this thread will jump on any recurrence in a recalled van.

Just today, my wife reported our 2018 stalled at an intersection. Just over 2k miles.....it had if got this correctly, gone into auto stop and would not restart. Had to shift to park and push start button again.
That's a tough one to pin down as whether it is a failure in the mode the recall addresses reaching into the 2018 MY -- I would guess not, since apparently there were no messages prior to attempting to move (whereas I believe the undesired shutdown immediately calls for the van to be put into park and restarted.)

But that brings up a question that has been brewing in the back of my mind for some time. This may not be the right thread for it, but since my van does not have ESS, and car rentals have not been ESS, I wonder how responsive an ESS van is to rapid acceleration from a stop. I ask because we have some intersections with stop signs that really need traffic lights as well as roads with basically non-existent acceleration lanes, and at peak times, you sometimes have to really punch it to get across / turn onto them safely. I realize that sounds like an oxymoron for safe driving, but the alternative in some cases to wait for rush hour to be over for really big breaks in the traffic stream. (And, also, as I said in earlier post, the main reason the stall issue always has me on edge.) A significant hesitation in the response to the acceleration demand would be problematic.

I don't quite know what details Chrysler would release that would satisfy anybody (you) - are we asking for a full code review of every system in the vehicle? Not realistic, not happening......

In terms of what they have said "In the majority of cases the stalling occurs at low speed, while decelerating, while at idle or while negotiating a turn" seems to indicate they have a pretty good idea of what is happening. Given that the fix is 2017s only, it's likely the fixed sw is already in the 2018 cars and so I would guess that they probably already has thus bug recorded in their system somewhere - it just took a push to get it as a recall.

@[email protected] PLEASE make sure to file a claim with NHTSA. It’s very quick and easy to do online with NHTSA.gov. You are not the first 2018 to experience a sudden loss of motive power like is described in the 2017 recall.

And I’ve been following this problem for over 6 months...I’ve read all of the NHTSA claims and also collected data of affected customers on this forum. To say that “the majority” of the cases occurred at low speeds gives a false sense of security. There are many reports of the shut-down occurring at highway speeds and in the middle of turns in front of oncoming traffic. Additionally, of all of the people who reported receiving a diagnosis and fix from Chrysler (including those who had engineers from Detroit flown in), none received the same diagnosis or fix as is described in the recall. (There is one driver who received a similar diagnosis, but she received more parts/repairs than the recall outlines.)

I agree -- file with NHTSA. Only when everyone details their issues can it be determined if these are trends or individual unique failures.

W.R.T speed -- this article cites 670 incidents:
https://www.allpar.com/news/2018/01/pacifica-trackhawk-recalled-39446
Only a small fraction of that number were posted here or on NHTSA (??) So it is very possible that the majority of the failures were low speed - but Chrysler does not deny higher speed occurrences. Not important to argue over -- any reader of this forum knows many happened at speed.

And then there are the fixes you mention. It is pretty obvious from the recall information that ANY fix applied to a van to date that had experienced the stall/no code/restart pattern was probably useless to prevent future incidents. But dealerships (and Chrysler team members) in good faith attempts to diagnose the problem may well have arbitrarily replaced/recalibrated things based on experience with similar issues, hoping to fix the issue. And then there is placating the (understandable) attitude of owners who want to see SOMETHING replaced.

I do not know how definitive that article is -- it claims the recall only addresses vans built before July 2017. When did 2017 production end? And yes, it is probable that whatever this software issue actually is, the changes for the 2018 MY may have, deliberately or not, precluded this software glitch. Why it will take the better part of two months to roll the software out to dealers is a bit mystifying, but does strengthen the argument that the 2018 change was not a fix but a basic change to that software - so that is why it may not be applicable to the 2017 setup.

FYI. Very interesting to read the recall chronology for the sudden loss of motive power on the NHSTA website. Suggest reading it if you haven’t.

Here is my cliff notes version:

1. Chrysler opened corporate investigation into the stalling on October 31. 2017.
2. Engineering team began on November 20, 2017 to work daily to study the problem & conduct testing & analysis.
3. It is found that a poor engine wiring harness splice causes 150 millisecond loss of power to crankshaft position sensor. The engine control software doesn’t handle the loss of signal well and shuts down the engine without setting a check engine light or storing a trouble code.
4. Revised engine control software was placed into Pacifica production after June 29, 2017.
5. Incident rate based on Chrysler report data is 4 cars per 1000.
6. The recall will consist of updating the engine control software to better handle brief loss of crankshaft position sensor data without causing a stall.
7. The entire production run of gas Pacificas (December 15, 2015 to June 29, 2017) is subject to the recall.
8. Dealers will begin performing the recall fix starting on March 2, 2018.

Anyone else a bit unsettled that the poor wiring splices that is the root cause is not being addressed, at least not as part of this present recall? I wonder if Chrysler decided that the software change is the quickest way to make the vehicle safer immediately with the least amount of downtime & cost. If some small portion of the harness splices are of poor quality, is Chrysler really going to leave them in customer’s vehicles? Will the splice get worse with age and environmental exposure and cause additional problems? I have an earlier build Pacifica and never experienced the stall problem. Does that mean I likely don’t have one of the poor quality wiring harnesses in my Pacifica? Questions to ponder. I wonder if those with the stalling problem will be satisfied with this recall repair.

@jerry17 I’m not referring to the data collected in the forum. I’m referring to the data collected on NHTSA. Of the 95 reports of a sudden loss of motive power, 23 drivers did not report a location or speed, 24 drivers reported that the incident occurred on the highway, 21 reported that it occurred at or in an intersection, and 27 experienced the problem while driving on city streets. So again, telling drivers that the majority of incidents occur at low speeds is an attempt at minimizing the dangerous nature of this defect, probably so they don’t have to provide loaners while they scramble to find a fix.

@Nails1 It’s hard to say if your vehicle is affected. I have an early build and I drove for a year before it shut down. Then they replaced the SCCM and it hasn’t shut down since. Some people experienced it days after driving off the lot, some drive thousands of miles before experiencing it.
To your second point, I’ve been in contact with a mom who experienced the problem 6 times. They eventually installed a data recorder and were able to pull a code which resulted in them replacing her crank trigger and crank shaft sensor (I believe these are the terms - either way, she had way more than an update performed.) Hers hasn’t shut down since. She is the only one I know of that has a fix that sort of correlates with the recall, so I find it interesting that they’re only calling for a software update. Either way, hopefully they have it figured out and this update will solve the problem.

Hi [email protected],

Sorry to hear about this! If you decide to visit a certified dealership for further diagnosis of your concern please send us a PM with your VIN for additional assistance.

The article makes it sound like the diagnosis was made on a single vehicle. If so, it's impossible to know how many of the reported incidents of stalling share the same root cause.

I've read through the whole Vehicle SHUT OFF WHILE DRIVING thread, and most of the related threads that have come and gone, and I see some variation in symptoms and causes. I don't think there is a single root cause, or a single solution. Also, just because a defect was found in one Pacifica doesn't mean it's present in all Pacificas.

More generally, cars have been stalling since there were cars. I can't think of any vehicle I've owned or researched online that didn't have some reports of stalling, and I've suffered stalls myself (not in the Pacifica). The failure modes are so numerous. Just to name a few that I've personally experienced: ECU connector not properly sealed, salt air corrosion, battery, hall effect sensor, cracked coil pack housing, loose grounding lug, voltage regulator failure. A total of ~10 occurrences of stalls in a bit over 30 years of driving, affecting 2 cars and 4 motorcycles.

I do not think this recall will end the reports of stalling Pacificas, and therefore I don't think it will end the drama.

A point I made a few times on different threads is that there are many posts that do not fit the stall/no code/(no issue) restart profile. Ditto for NHTSA reports. This recall specifically addresses that event sequence.

A legimate question raised by someone is the extrapolation from one duplicated incident. We do not know if they looked at other harnesses and found the same flaw. Occam's Razor is our friend here. NHTSA (and our fellow forum users) will jump on Chrysler with both feet if recalled vans continue to experience this failure mode. But currently we have one solution and only time will tell if it does the job.

The larger implied question of the long term integrity of the harness remains to be addressed.

Interesting issue and thread. My Limited was running in the garage after starting it and I got out to bring in the recycling receptacle. As I was outside the van I noticed the engine stumble but it kept running. It's only done this once. Other than that the only other issue I've had was the drivers window refusing to go up after putting it down a few times. It would start to go up an it would get about a third of the way up and go back down. I have an early model and I love it so far. I hate the rotary shifter though. Don't know what they were thinking with that.
