2018 stalling issues unresolved

Our new Pacifica purchase began in July 2018 when we purchased the 2018 Pacifica "S" touring non/hybrid model. This vehicle is beautiful and came with every option Chrysler had except the vacuum. Now we selected this vehicle because of the Advanced Safety Tec Group options witch contains all the extra safety features that reassured my wife to get back behind the wheel so shortly after the accident that led us to this vehicle.

So our issues with the vehicle started from the first weeks that we owned it. My wife and I had the vehicle stall twice to each of us but did not attribute it to stalling, we actually thought it was a feature that had the engine turn off while at a light to save gas. This stalling happened 4 times in July and August. It wasn't until we were both in the car on September 12th, 2018 while I was driving through an intersection at approximately 5km's per hour that the vehicle stalled and we were in a near collision had it not been for the attentive driver coming towards us to swerve out of the way. All the lights came on the dash and we had no brakes or steering. I was able to take a short video of the dash that showed that the airbags had deployed and that we had been in a collision. Prior to my video there were a number of waring lights that came on that the vehicle warned us about:

1. Low oil,
2. Lane Departure Warning,
3. Park sense front problem,
4. Advance Brake assist,

My wife and I were talking amongst our selves when we realized the 4 other times that we thought nothing of was the same situation.

Once we were safely out of harms was we took a quick video with what appears on the dash. Now to get this vehicle started again we had to do the following in this order only:

1. Shift gear to park,
2. Place foot on brake,
3. Press the starter button,
4. Shift to Drive,
5. Disengage the emergency brake.

We took the vehicle to our Chrysler Dealership that same day and they kept it for a couple of days having one of their service person drive it to and from home trying to replicate the issue. They could not and advised that they found a loose wire related to the ABS and that had fixed the issue.

This brings us to the event on November 28th, 2018. Very similar situation as above the only difference was I was alone in the vehicle and traveling approximately 10km/hr. This time when the vehicle stalled I was not in any harms way. I took the vehicle to Chrysler and the service personnel did the same stuff as above except that they flashed the software with a new update that the service man says would fix that issue. This time I engaged FCA Canada with my concerns as well as I didn't believe that "flashing" the software would solve the problem and neither the dealership or FCA would provide me with any document to prove it.

Since November 28th, 2018 my wife has not driven the vehicle and refuses to have our 3 children in it because she doesn't believe it's fixed. So this brings us up towards the start of February where I was able to sporadically get my wife to come for drives in the van (We would never go more that 25 km's away). Now to give you an idea on how much its driven, in 8 months it only has 5700 km's. It has spent the most of the time tucked away in our garage until my wife builds up enough courage to drive it because she doesn't believe it was ever fixed.

Well that brings us up to the final time of February 28th, 2019 (7th time), when I was driving with my wife in the vehicle in our town. The vehicle was travelling at approximately 60km's per hour when it stalled in a live centre lane, of a three lane highway. I could not steer or brake because the vehicle lossed all power. I have a video of the dash sequence again after the fact and was taken after it was safe to do so. There was a large semi truck that initially had to swerve to miss us when we were stopped and that was a heart pounding situation to say the least but we came out of this unharmed.

We were less that kilometer away from the Chrysler dealership and took it there immediately for the "scan" that they said they could do. All 3 visits have yielded no errors during their scans and it is still there since February 28th, 2019 because they have no idea what the problem is or how to fix it. FCA has told the dealership to replicate the problem and none of the service personnel have any idea on how to fix.

So we are at aloss since we have a vehicle that can't be fixed by FCA Canada and we have supplied all our information and videos to their engineering department. The service personal are fed up with our vehicle. They have gone as far as testing the gas and oil in the vehicle, tested both batteries, flashed the software and put 1500 km's on it in test drives to replicate the issue. The vehicle is not under any recalls related to our issue and the service personnel advise they have never heard of the 2018 gas Pacifica doing this.

Now after reading these posts I've noticed that others do exactly what ours does.

The dealership has had our vehicle for 15 percent of the time that we have owned it and they have put on 1500 km's in testing it. The vehicle has been in the shops in total 38 days. Still as of today, the vehicle is in the shop and we have had a rental for the last 32 days.

Anyhow thanks for listening.

Thanks for sharing your experience. It is scary to think a vehicle can behave so unpredictably and more than frustrating that no one can figure out why. Today's vehicles are complex electronic/mechanical systems controlled by software. There are failure modes the software engineers never thought of. Its troubling that the software's response to whatever sensor anomaly was received is to shut down the engine when the vehicle is in motion. It should never do that. The FCA engineers may not be able to determine the specific glitch that caused the software to shut down the engine but they can determine and fix the software code that responds in a such a dangerous manner. Good Luck.

Thanks for the share. I empathize with the disappointment and frustration on having to endure such a scenario. Luckily, I haven't had to experience a full vehicle shut down myself, but I will take your share and prepare myself should it happen. We bought our Pacifica in August of 2018, with ~ 9,800 km driven thus far.

Knock on wood, only issue we've experienced is full loss of power steering which has been remedied thus far due to a loosely connected ground cable.

"full loss of power steering which has been remedied thus far due to a loosely connected ground cable."
First time I have heard of that problem. Were you driving when the power steering failed? A bad ground can be a gremlin affecting almost anything. And I wonder if the stalling issue can be traced to this...

I have never tested this, but does the steering and braking fail when the engine dies? My experience with other cars in the past is that they become harder to steer and brake, but they don't totally fail.

I for one, don't know. It stalls JUST as you are stopping, and I am too busy doing the start up routine to notice (shift into Park, press Start button, shift back into DRIVE.
When ESS engages, van engine stops about 1 full second after the wheels are stopped. There are no bells or warnings on dash.

The stall occurs a half second or so before van stops. Engine shudders as it stops, and lights and bells immediately activate.
I just don't know about the steering and brakes, as I am already stopped.

Yeah, I was responding to this thread where the user mentioned power steering loss, identical to what I experienced. Electrical things can be super tricky, especially with poorly grounded components, which who knows, could very well be the cause for all of these issues.

"...The dealership noted that there were some error codes with the voltage being too high. After a day of back and forth between technicians and FCA engineers, it was diagnosed that the Intelligent Battery Sensor (IBS) was at fault, since the instrument cluster was reporting lower voltage values than actual (Electric Voltmeter was measuring 15% higher voltage readings, ie 16 V actual vs 14 V IBS). They also noted that the ground cable appeared loose, which was re-tightened. I still think its a toss up as to what is truly the root cause, my guess is the grounding."

I notice that the Intelligent Battery Sensor was also found to be at fault...Can you post the dealership work order?

Took a snip it for you. Similar to your situation? The tech verbally advised that they noticed the ground was loose, but that wasn't captured in the comments.

Thanks for posting. Very interesting information. I hope that the FCA engineers can use the information to help remedy some of the problems that SOME of the Pacificas are having. It would be great if more owners would post work orders. I am having almost no problems (hood corrosion fixed) with my '17 Pacifica.
