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.

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.

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 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.

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.

2018 Chrysler Pacifica. Consumer writes in regard to problems with its automatic stop/start feature. The consumer stated the vehicle was in for repairs several times but the dealer only supplied a rental one time.

The end of 2021, Began not starting requiring many pushed of the start stop button; stalling when in motion on roads; gas pedal tight not depressing, engine light on and off, side auto doors often wouldn-??t work automatically (battery new); was lurching and chugging randomly, over time very frequently. Nov 22-?? had start stop battery replaced & fuel pump sensor. still lurched etc..worsened..late 2022 began frequently stalling, not starting, pedal would be stiff, lurched daily, stalled frequently during motion & upon first acceleration..start, try to go..stall out..finally jan 5, 2023, wouldn-??t even turn over-just clicked-shop diagnosis said few codes referred to electrical panel issues.. replaced spark plugs, starter, got home, next morning, same thing ~no turnover. problem not solved. another shop, where it sits today-found cracked engine block($12,000 estimate to -??attempt-?? replacing engine). deemed total loss as value of van is less. This has to be a defect gone undetected for some time, having built up damage over these last couple years.Many of issues are identical to recall (2019-2022) listed problems. Regardless of any recall being labeled as inactive, this vehicle is clearly a result of manufacturing issues. A 2018 doesn-??t just have these problems when it-??s cared for.We have four children & currently have no mode of transportation~two shops since January 6, -??23, prior year of worsening symptoms. A safe, reliable vehicle is vital for our family-??s functioning. It-??s now at Lee-??s Auto-seen in picture. Excel Auto was first repair attempt Jan.6. We will not be reimbursed by insurance for -??mechanical failure.-?? Our loan is $18,000 outstanding. We pay $459.65 each month, and are responsible for remaining balance. Why should this happen to us. We certainly can-??t purchase a second vehicle in conjunction with this loan. Your quick action and assistance is appreciated and direly needed.

Leaking coolant in cylinder 5 leading to a misfire and check engine light. Dealer reports this is a known issue and only replacing the engine will fix, but Chrysler isn-??t doing anything to fix it.

Check engine light and start/stop light

- Carrollton , IL, USA

At Approx 92,000 miles, the head gaskets failed and allowed coolant into the cylinder heads causing the engine to overheat and the cylinder to be damaged and need replacing. The repairs would have cost me $3386, but thankfully extended warranty covered $1900.

Blown Head Gasket at 77K miles

- Cincinnati, OH, USA

Began with a misfire in cylinder 1 that would chug on startup, the smooth out. Had a check engine light come one, which showed the misfire in cylinder one. Brought it to the dealer, they noted low coolant levels and possible blown head gasket. Had only 108,000 miles. They could not get to further review of the motor for two more weeks, so we were told we could pick it up and bring it back. One hour after leaving the dealer, the motor overheated. There was no coolant whatsoever in the vehicle. After calling the dealer, we were told they forgot to put coolant back into the vehicle before were could pick it up. The next day, the van is no longer usable. It began stuttering continually.
