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.

Car began to idle roughly and the check engine light came on. A scan returned the code that indicates a misfire in cylinder 3 of the engine. Our local service station was unable to fix the problem, but stated it could be a leaking head gasket. We took the car to a dealership, where they diagnosed a crack in the engine block, with coolant leaking into the engine cylinder. The dealer service department is saying the engine needs to be replaced, at the cost of around $16,000. The car is at around 85,000 miles, far too early to have engine problems of this magnitude. This issue has been widely reported among other owners of 2017-2022 Pacificas...all similar cases. A misfire in an engine cylinder (usually 3 or 5) which ends up being diagnosed as a cracked engine block requiring a replacement.

Noticed that I have been low on antifreeze/coolant over the last few thousand miles. Reading other complaints, it seems as though the engine block becomes warped around 60,000 miles causing the engine to burn coolant. Chrysler will end up replacing the headgasket for around $3-4,000 which ends up lasting around 10,000 miles before the same issue occurs. Just surprised that a car with 60,000 miles would fail. There really should be at least a TSB on this.

- Frankiln, WI, USA

Pacifica with 68000 miles giving a P0303 cylinder 3 misfire. After taking to two separate mechanics, they both confirmed its a blown head gasket leaking antifreeze into cylinder 3. Going to cost $4000 to repair.

With Chrysler, recalls are never ending. Last year there was battery recall (Z11) that took 10 months to fix. Just after I got that fixed in Dec-2022, in Feb-2023, we have a new recall, where the vehicle is pretty much rendered useless as it can stop anytime on freeway. My friend who has the car had the vehicle suddenly lose traction and stop in freeway (this happened last week). Fortunately nothing happened as he was able to exit safely. Given it hit so close to home, I am scared to drive my Chrysler Pacifica car anymore. When i contact Chrysler for possible remedies like offering a rental assistance e.t.c they are adamant and refuse to help in anyway. I don't understand this ; I have brought a car in good faith and for no fault of mine, i need to spend on "rental car" now? In prior recalls, Chrysler did offer Rental assistance, but this time around they seem to refuse to entertain any such help. This is really a very precarious situation for me. My wife constantly uses this car to shuttle kids to/from school/activities and frequently needs to use it on freeway. I am really concerned for my family's safety and well being. I think this unfortunate stance by Chrysler is placing us in great danger. Pls help!!

Pacifica 2018 Model. The engine light started coming on. The car started shaking strongly at start but gets normal after some minutes. Took it to dealership. Dealership said same problem you are discussing. Coolant was gone. Head gasket gone. The cylinder 5 misfiring. The engine needs to be replaced. This problem is affecting just too many owners. Request Chrysler to acknowledge that it is a problem. My car has only done 73000 kms and I have taken very very good care of it with regular maintenance and got it fixed only from flagship dealerships. Seems warranty just expired month ago. I am the second owner who purchased it at 21K km. The dealership told me that they may not fix it under goodwill as I am second owner. I am left with no options.

I was driving with my family about 30mph and for no reason, the vehicle lost power and I coasted and braked to a stop on the side of the road. Nothing I did would bring any response from the vehicle while it was coasting. A short time later while stopped, I was able to turn the vehicle off and then was able to turn it back on. This happened about a year ago and I thought it was strange. It has not re-occurred. I did not seek out any resolution until I found out about the 03A recall (NHTSA 23V-010). That recall describes what happened to me. My vehicle is currently undergoing multiple attempts to perform the Z11 recall (NHTSA 22V-077) so I do not currently have access to my vehicle.

Check engine light stays on and car does not charge. Both recalls were done at the dealership

I kept having a check engine light come on with the code P0305 for a cylinder 5 missfire. It turns out the cylinder is broke and leaking.

Check engine light appeared 01/26 out of nowhere. Engine started to idle rough onbstartup but cleared after a few seconds, checked code with OBD2 and it hit P0305. Took to dealership for repairs 01/27. We live in the middle of nowhere and having this vehicle fail in the middle of the no-cell-service drive could have caused us to be stranded in the snow, especially with the winter we've had it could have been a catastrophy. Dealer originally flagged fuel injector as the reason. Picked up vehicle on 01/31, check engine light returned on 02/01 and we immediately contacted the dealership again. Returned vehicle again on 02/02 and it has remained in the shop even as of today 03/10. Reported back to us that there are cracks in the Engine block are causing coolant to leak into cylinder 5. Dealership confirmed they have seen multiple 2017 and 2018 Pacificas have this same issue. Even went as far to say that those with a perfect maintence done on the vehicle were subject to this same issue. 3rd party inspectors have also checked the vehicle for extended warranty purposes. Many reports of the Pentastar 3.6L V-6 seem to show a commonality with what the dealership reported about the 2017 - 2018 Pacificas engine problems. Chrysler has not responded to outreach for assistance and as the cost to repair sent to warranty company is thousands of dollars over what the current value of the vehicle is worth. Chrysler seems to be dodging responsibilty for this blatent issue.

First, it started with the stop/ start not working. We took it to the shop they said we needed a new alternator. Costed us 700$. Well the problems did not stop. The check engine light did not go off after a few times of driving it (the mechanic (crystler mechanic) said it would after a few times of driving it. Well then it started rumbling when u turned it on. Called and they said bring it back in. Well we planned on doing so but then the van wouldn't start. We had to get it towed. Well they said the fuse had blown. So when they replaced that they noticed white smoke coming out and all the coolant gone. They said it is most likely the cracked engine block which is gonna cost over 12000$ to fix. We already owe money on the car. We cannot afford this! We have 4 kids and this is a safety issue !!! Now we are out of a vehicle and still owe on it !

Coolant leak as well as the other problems that I reported.

- Enon, OH, USA

The car starts blowing out white smoke when started. Mechanic thinks it could be a blown gasket or Crack in engine block. The cable fuse blown as well. The vehicle did not start so it was towed to the mechanic.
