Our '18 PacHy was purchased new in Nov '19, had about 15k mi as of Friday. Driving from Phoenix to Palm Springs on Friday afternoon, and it randomly lost power cruising at 70 mph. Heard a ding on the dash, both the Power and Gas gauge needles swept down, MIL light on, a message on the dash to place the vehicle in P to start the car, no acceleration (no engine). Still had steering, so able to make it to the shoulder.

Being stranded on the side of I-10 in the Phoenix metro area during rush hour when its 117* outside sucks, for sure.

Once pulled over, pushing the Start/Stop button while in Park would only turn off the radio console, dash remain lit. Never restarted (which means no A/C). Accessories worked.

Ended up dying right across the interstate from a Chrysler dealership about an hour before they closed, one of the service writers came to pick up the wife and kids so they can get safe/comfortable, very appreciative to him for that because we were stuck in a bad place (between two on-ramps - no where to walk off the Interstate) - AAA took about 90 minutes to arrive 馃檨

Towed to the dealership, dash still light up like Christmas tree and the PacHy still 'on' because we couldn't get it to turn off. 12v battery finally died about the time we found a ride back home to grab my truck.

No word yet from the dealership - found a couple other threads about random deaths/restarting - the service writer says he never heard of one giving up the ghost while driving. Thoughts? Will keep folks updated as the info becomes available.

Dealership just called, didn't find anything wrong with the PacHy other than a dead battery from staying 'on' after it died. Charged it up over the weekend, it appears to run/drive just fine now so they said to come by and pick it up.

Wife is understandably hesitant that nothing of concern was identified other than a glitch in the Matrix. I guess we just accept that it can choose to crap out at its convenience 馃槖 It is the original battery, might just put a new battery in it tonight and call it good?

Before you pick it up, why not ask the dealer to check the 12V battery for you?

If the battery is tested and fails, it should be replaced under warranty. If the dealer doesn't replace it, I can understand you considering replacing the battery before a long desolate hot drive between Phx and Palm Springs. I don't have a hybrid, but have had two 12V batteries on my gas van replaced.
Be sure to take jumper cables if you don't get the battery replaced.

I don't know if this is relevant, but has your van been inspected and/or repaired for the terminal corrosion problem recall? This does involve the 12v circuit.

In any case, I don't see how recharging either the 12v or the traction battery is a solution to the Pacifica dying while driving it. Your 12v battery is probably destroyed if it was let to discharge completely.

Here's a thread (see post #8) with photos about how to change a 12V hybrid battery if needed.

Dealership completed the recall repair with a gasket, said the only repair performed was charge the 15000 watt battery over the weekend; that's all that's documented on the repair order.

Of course, on the 40 mi. drive home the 12v battery light illuminated and A/C barely worked. Bought a new AGM H6, installed it, and now I'm met with a 'Service Electric Hybrid Vehicle System' alert and the PacHy is locked up in the driveway. Was careful not to grpund out the (+) terminal. Changed dozens of batteries in my time, this was pretty straightforward so for the life of me I can't understand what's F'd now. :confused:

Guess I'll call Roadside tomorrow and have it towed to the dealership by our home.

More to come.

You need to call Chrysler and get them to help your dealer with this nonsense. They are obviously in over their collective heads on the problem. That brush-off with the battery charge was useless as any mechanic would know. @ChryslerCares are you following this?

Here's a FCA Customer Care phone number you can call: 1(866) 275-1420.

To private message @ChryslerCares click on their name. If you are taking the van in tomorrow you might get faster results by calling FCA and having their techs help the dealer techs. FCA might have a recommendation on which dealer to have the van towed to since it is still a pretty new type of vehicle and some dealers may have more experience with it than others.

Any suggestions @stop-eject @m0ebius604 or others?

Without knowing the codes and the battery voltage it is hard to tell what is going on. A dealer can't replace battery unless it fails a special test they have to perform. The 12 battery seems to be involved in a variety of problems. In my case linked above, the dead 12V battery killed the high voltage battery controller. But I still don't know what caused the deep discharge of the 12V battery. It worked for a while after they charged it. My new van started driving funny one day- my wife described it like driving with a parking brake on. MIL and turtle on the dashboard. By the time I got to the van it drove normally, the turtle was gone, but the MIL remained. Took it to the dealer, they pulled a bunch of unrelated codes. The dealer called me later telling the the MIL went off while he drove from the service bay to their parking. They did nothing and the problem didn't return since. Some mysteries remain unsolved.

Understood - it's now at a different, local dealership. The SW seemed more interested in the issue than the previous, and she suggested that they'll test the battery this time around. Fortunately, this time the MIL seemed to have stuck and the battery has enough juice to keep systems lit (at least it did when it left this morning).

Now you've got me worried....1st I live in Bermuda Dunes near Palm Springs so if you need help around here I'm available.....like you I purchased a 2018 in August of 2019 as a "left over" and later learned of all these battery issues...the dealer replaced the battery when I bought it so they knew something I didn't but in 11,000 miles it's been flawless..not a single problem. I'm going to Las Vegas tomorrow for a few days and now thinking of driving my 300 instead....please keep us informed how this works out.

Get AlfaOBD if you want to know more about the codes. No other aftermarket software can decode them.

Dealership continues to tease through the issues - really appreciate their diligence in rooting through the problem rather than dismissing the issue as a low battery charge.

Sounds like they had some challenges getting power to the 16kw battery,recommending at a minimum a replacement 12v battery and OBCM for starters. Will continue to update.

Sounds very similar to stall out issue I just had with my 2019 hybrid (14k miles). First happened while stopping at a light and then at about 65mph (towed twice, now at a dealer). Currently waiting on parts for a PIM replacement. Approaching 2 weeks now.

Two very similar events (see photo) have caused me to turn to the dark side of the internal combustion engine. Here's my story. I bought a 2018 Hybrid from Airport Chrysler in Orlando while on a Disney vacation in December. The Pacifica had 3700 miles on it. While driving home to NC, the van broke down on I-95 in Jacksonville (about 200 miles after buying it). It was a scenario much like yours. The AC stopped working, the dreaded "Turtle" warning light came on, and with a mile we were stuck in a very dangerous position on the Interstate. AAA and a wonderful Jacksonville safety officer saved us. Jacksonville Chrysler did a good job in diagnosing the problem - debris in the hybrid cooling lines. That solved the problem for another 3700 mile. Then it all happened again (in less life threatening circumstance). AAA towed the Pacifica to Neuwirth Chrysler in Wilmington NC where their technician charged the battery and took the van home for the night for a trial run - it failed again. at that point they were uncertain as to what to - and got little support from FCA. As you noted, the uncertainty is unbearable. The dealership offered an acceptable trade, and I am now the owner of a gas powered 2020 Touring L Plus. I hope all goes well with this one and that your problems can be resolved more effectively than my hybrid's.

same happened to me, ended up needing a new PIM. Dealer worked with Chrysler tech to run advanced tests.
