Van has been clunking/slipping through transmission when accelerating. Stop/Start function error relayed and had a rough idle noticeable when started cold. Car would shut down on occasion when coming to a stop. Battery was recently replaced, assuming due to start/stop battery(also been replaced) draining main battery. Technician indicated Misfire on cylinder, coil swapped, spark plugs replaced and 100,000 mileage maintenance completed per recommendation due to scope of work. Van returned then upon first start, extremely rough idle and exhaust smelled the worst I've ever smelled, choking even. Van taken under warranty at least 2 times for transmission and abrupt shutdowns due to safety concerns with vehicle. Never replicated at dealership.

The contact owns a 2018 Chrysler Pacifica. The contact stated while driving 30 MPH, the vehicle started jerking. The contact stated that the air bags warning light was illuminated. The contact was able to drive to her destination. The contact took the vehicle to the local dealer, but the mechanic was unable to duplicate the failure. The vehicle was not repaired and continued to experience the failure. The contact took the vehicle to a second local dealer, Miami Lakes Chrysler (16600 NW 57th Ave, Miami Lakes, FL 33014: (305) 820-3814) where it was diagnosed with needing the radiator to be replaced. The vehicle was repaired but continued to experience the failure. The contact took the vehicle back to Miami Lakes Chrysler and made them aware of the failure. The dealer serviced the vehicle under NHTSA Campaign Number: 23V010000 (Electrical System, Hybrid Propulsion System). The vehicle was repaired but continued to experience the failure. The manufacturer had not been informed of the failure. The failure mileage was approximately 51,000.

On three recent, separate occasions, the vehicle has lost acceleration while making a left hand turn from a stop (date listed for this incident is most recent). No visual or aural warning indications have displayed on the dash during or proximate to these incidents, but the car felt like it went out of gear while making a normal left turn. Pushing or releasing the throttle only affected engine RPM, not any acceleration, so it felt like we were only coasting. It lasts longer than a normal shift, more than a few seconds, before power is sent to the wheels again. On two of the occasions there was oncoming traffic approaching the intersection. If the power had died any sooner in the turn I'm not sure I would have cleared the intersection in time with what little speed I had gained, increasing the risk of collision. I am taking the car to the local Chrysler dealership tomorrow for inspection and hopeful diagnosis/repair. I can't replicate the issue on demand, but after 3 separate occasions, it is an unmistakable feeling. Based on the clunky, jerking shifting into gear that sometimes occurs with the vehicle outside the above-described incidents, I believe it might be transmission related, but I can't be sure.

At 63000 miles engine misfire occuered needing to replace the head gasket causing leaking coolant into the combustion chamber causing a misfire. Very concerning considering relevtivly low milleage and potential ongoing engine concerns. Wife and children were driving when check engine light went on, resulting in misfire causing car to shutter and stiring wheel shake. Car is curently being serviced at the dealer. There were no early indicators prior to this incident.

While driving home with my pregnant wife and kids, our van seemed to cut off and coast. I got no response from the accelerator pedal, and there was a message on the dash saying "Shift to P to Start". The check engine light also illuminated. Luckily, we were able to coast and pull over in a neighborhood. I was able to shift to Park and restart the van and finish the drive home. However, the same issue and message appeared while I was parked in my driveway. The van is currently at a local Chrysler dealer for further inspection and diagnosis.

2018 Pacifica Wheelchair Accessible Van has on several occasions without warning, decelerated and stalled. Displays Place into Park and restart. Van starts sputtering & decelerates. After pulling over, waiting a few minutes it does start again. We've had the van over a year without any issues until now. We did have it at a dealership for a week. They were unable to find anything wrong with it. Very frustrating as we use this van to transport our disabled daughter. Recently we received notice of Class Action Lawsuit for this problem. Doesn't help me right now.

Van started running slightly rough in the mornings if the engine was cold. CEL eventually came on with a P0304 DTC. I replaced the igntion coils and spark plugs since the van was right at 80,000 miles. Seem to run fine for a day after, then issues came back. Took it to the dealership for more in-depth troubleshooting and repair. They failed to do anything after almost two weeks except that now my van wouldn't start. Took the van to a non-dealership affiliated repair shop and they said the starter had failed, but the engine passed the pressure check of the head. Waited almost another two weeks for a new starter, mechanic got it back together, found some coolant coming out of the exhaust manifold and recommended adding leak stop that there might be a small casting issue with the engine. They added leak stop and returned the van to me stating they think there was a small hole in the engine from casting and that coolant was getting by and causing the misfire. Subsequently, the coolant would then travel to the catalytic converter where it would burn off but caused the cat to be much hotter than normal and that was in-turn frying the starter which is pressed up right next to the cat. The van continued to run rough for a couple days before it finally wouldn't start again and now i'm having to have it towed back to the shop. I suspect the issue may a issue with a warped head or something even worse. A cursory search of both online forums and NHTSA reports that this is not a one off or new issue and only seems to be getting worse and more prolific as the average age of the fleet pushes towards 80-100K+ miles. Modern vehicles should be able to go 150-200k miles before head gasket issues become a serious concern.

Sept. 12, 2022 - Ever since we have owned this vehicle, we have experienced this issue with the cruise control. Speed increases while driving downhill highways and sometimes on pretty level highways. When I decrease the speed on the controller, it sometimes maintains the speed for several seconds (slow to respond) in order to slow down while coming up behind another vehicle. I therefore need to break or turn off the cruise control. Very unpredictable. Also, speed changes a lot which sounds like shifting gears back and forth while going uphill. I had contacted the dealer originally and was told this is normal. This is ongoing. Happens every time when driving on the highway. Safety concern. The other issue we had experienced while driving on a city street, we got some odd sounds, what sounded like it was coming for the transmission. Like shifting sounds. and on another couple of occasions, we got a kind of (clunk) noise. Not sure-??hard to explain. Only happened a few times over the last several months. and was brief. This in not ongoing, but a concern for failure and or safety. No warning lamps or messages

The engine overheated while driving and required immediate attention, leaving me and my family stranded on the highway. The original code that tripped the check engine light was for a misfire in Cylinder #3, upon further inspection at the dealership it was concluded that the issue was a blown head gasket, causing the engine to overheat and fail. This was confirmed by the dealer. I have sent the issue to the manufacturer as well. There are a number of these issues in public forums. It is apparently a well known defect.

- Coleman, MI, USA

I have owned van for 1 year and taken it into the shop 6 times for blown head gasket, leaking coolant, over heating due to leaking coolant, and now it needs a new ignition coil and spark plug due to coolant leaking. Check engine light pops on every time and the van notifies me that the engine is over heating. Must pull over on the side of the road to let car cool down. Problem has been confirmed, taken to car dealer at every instance. After issue has been taken to dealer and "fixed" check engine light returns after 4-6 weeks, every time. Paperwork can be provided on request.

My transmission jerks when shifting to first gear and sometimes when I'm going slow it feels like it is not getting gas and won't go then it will kick in and take off with acceleration that is more then it should be. The garage reset it back to manufacturer settings, but it only lasted a couple of months and it is doing it again. I'm afraid it will cause an accident.

- Erie, PA, USA

Van showed the message "Stop safely the vehicle will shut off" and stopped on the road. It was immobile for close to 30 mins. I was able to start and drive back home. It again stopped on the road on the way to the dealer. I have seen number of complaints on this van on the internet. My van is still with the dealer and they could not fix the problem in the past 15days

Honestly it-??s been one thing after another, including engine, power train and electric issues

- Newcastle , CA, USA

Vehicle shifts really hard. It did on date listed but has ever since. The dealership identified problem and ordered parts but never called back when parts were ordered and is now past warranty to get it fixed.

- Caledonia, OH, USA

The transmission shifts very hard. Extremely hard. On two occasions, vehicle has lost power and had to merge through Atlanta traffic to the shoulder. Extremely dangerous. We-??ve taken it to the dealership service department both times and no one can find anything wrong. No recalls. We love this vehicle but are being forced to buy another brand. This is the 2nd Chrysler product that has let us down.

- Tifton, GA, USA

Vehicle stops in the middle off traffic. Engine will start but car will not move. Numerous warning lights appear such as:vehicle not in park (it is in park), rear brake assist unavailable, shift to P then desired gear, service electronic stability control, park brake temporarily unavailable. The vehicle accelerator pedal can be floured and the RPM is only 1500. After tow trick delivers me home, the vehicle will miraculously drive unimpeded for days and weeks until the very same thing happens. Repair facilities have said they can find nothing wrong/cannot duplicate.

- Chula Vista, CA, USA

Transmission doesn-??t shift properly. Highway going normal speeds, switch lanes and when pushing gas peddle, it instead slipped and decreased speeds almost causing an accident. Dealership says nothing is wrong. Eco start stop illuminated and front collision warning light also on.
