2018 Chrysler Pacifica Engine

While driving the engine light came on. I have had the van 5 months at this time. I took it to the dealership where they diagnosed it with a crack in the block. I have extended warranty, BUT the service advisor told them that this is a common issue with these vehicles and they see it all the time. NOW, my warranty denied the claim to do "MANUFACTURER DEFECT". Of course they back peddled and told warranty that it was due to a piston or detonation, TOO LATE, warranty will not cover it. Chrysler sent out an engineer who stated it was not a manufacture defect and that my warranty should cover it. Which they won't because all they heard was "MANUFACTURE DEFECT". My van has less than 100,00 miles on it and now I have no van. I can't afford the 12K for the motor and the 21K I still owe one it. Come on CHRYSLER do better for us!

Check engine light and auto start/stop function stopped while vehicle began to run rough and slow approximately one week ago on my way home from work. BARELY accelerated to 25 on my way home. Nearly got hit as it did happen in traffic. Took it to Auto Outlet Service Yard for diagnostic purposes. Mechanic stated blown head gasket and needs new motor estimate 4500 dollars only had vehicle 6 months get oil change regularly, drive to and from work and school only.

Head gasket needing replacement due to cylinder 5 misfire at 7 years/55,000 miles. This appears to be a defect in the engine for this year and 2019 year. I am willing to be a named defendant if there is an opportunity to go after Chrysler for this as they are offering no assistance for this known defective engine.

The contact owns a 2018 Chrysler Pacifica. The contact stated that while driving at an undisclosed speed, the vehicle stalled, with a misfire coming from the engine. The contact stated that the check engine warning light was illuminated. The vehicle was able to restart. The vehicle was taken to the dealer, where it was diagnosed and determined that the cam shaft had failed and needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 143,000.

The oil filter housing adapter is made of plastic. They frequently break and mix the coolant and oil, leak oil out of the system and into the heads. This is a known problem and engineering solution of an aluminum housing has been made. They should recall this part and replace or reimburse for people who have had to do this already.

The contact owns a 2018 Chrysler Pacifica. The contact stated while driving 75 MPH, the vehicle lost motive power. There was no warning light illuminated. The vehicle was able to restart. The vehicle was taken to an independent mechanic to be diagnosed. The contact was informed that there was a misfire in cylinder #3. The vehicle was repaired; however, the failure recurred. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 105,769.

Leading up to the failure the smell of coolant was noticeable after driving the van. Coolant reservoir never showed a drastic decrease in coolant but I would top minimally every 6-8 months. I took the van to 3 different shops stating that I smelled coolant with zero evidence of a leak. System was tested and found not be leaking coolant at each shop and recommend continue to drive the vehicle. At 61,000 miles CEL came on with code P0305. Code was for a misfire in cylinder 5. CEL ended up going away only to come back a few days later. Engine never displayed any signs of overheating and consistently runs at a normal operating temp according to the onboard display. Inspection showed coolant pooling in cylinder 5 and wear on the camshaft. Oil changes completed every 3k miles and the recommendation from shop was to put in a new engine in a car 1K beyond the warranty. Reading numerous posts suggests that this is a continued issue that Chrysler doesn't want to take ownership for on their products.

Engine has 85000 miles on it and has never missed an oil change or service. Car has never overheated, but a check engine light has come on for a misfire in cylinder 6. Dealership indicates there is a blown head gasket and pitting on the engine. This car is too new to have such significant engine problems and it looks like it is a very common occurrence.

Vehicle starting having some issues on startup. Check engine light came on and immediately took it in to the local shop to have it inspected. The HEAD GASKET had gone bad--while not fully blown it was leaking coolant into the cylinder and would have left us stranded on the side of the road with our three little kids if it completely failed when we were out and about.

Blown head gasket and leaking coolant at 65,000 miles with regular maintenance. $6000 repair quotes.

The contact owns a 2018 Chrysler Pacifica. The contact stated while driving 25 MPH, several unknown warning lights Illuminated. The message to “Pull over and turn off Vehicle” was displayed on the instrument panel. The contact pulled over to the right side of the road and the vehicle lost motive power and stalled. The contact was able to restart the vehicle after several minutes; however, the message remained displayed while driving to the residence. The dealer was contacted; however, the dealer informed the contact that the VIN was not under recall. The contact stated the failure reoccurred on several occasions. The vehicle was not taken to the dealer to be diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure but offered no assistance. The approximate failure mileage was 89,000.

My car wasn’t driving properly (2024) so I brought it to a Chrysler dealer in Mt Juliet TN. They did some cylinder work for $2300. The vehicle had approx. 85000 miles on it. The check engine light came on again at about 90000 miles (2025) so I brought it to Christian Brothers in Mt Juliet TN and they did spark plug work for $1700. The check engine light came on immediately after and the same auto mechanic said it was the head gasket. I brought it to Car Max in Nashville TN to sell it but they didn’t offer enough and said the error code indicated a cylinder misfire.

At approximately 78,000 miles and just over 6 years old, my vehicle experienced a blown head gasket and potentially a warped engine head. The estimated repair cost for this issue is over $7,000. Chrysler really need to look at their quality issue, I will never buy a Chrysler product again.

Major engine damage at 83,000 miles (blown head gasket). Vehicle was well maintained. It seems that this is common issues with the Chrysler Pacificas.

Cylinder 3 keeps failing and head gasket keeps failing. Have had to replace the head gasket 3 times now over the last 6 months. This last time it lasted 6 weeks. Code was P105D.

extreme premature failure of head gaskets. only at 80K miles and this is a known issue with my year Chrysler Pacifica requiring a 3500 dollar repair. the car has never over heated prior to this failure.

Head gasket failure..engine replaced with factory long block by independent garage at owner expense

At startup there has been a noticeable misfire, and a rough start condition. Check engine light came on shortly after buying it (used) with a P0305 code and low coolant was observed - Cylinder 5 misfire. Sparks plugs were replaced and coil was swapped and there was an immediate difference in it running better and less of a noticeable misfire. few weeks later check engine light comes back on and noticed there was a drop again in coolant levels. Topped off coolant and re-checked everything and P0305 code returned. Code has been intermittent but just got it into a shop for further investigation and found a new head was needed where this is a common problem in shops and Chrysler is now recommending to have the head replaced as part of this fix due to problems on their end. Shop it's at won't take the risk of a head replacement, and we'll likely have to go through the dealer. There was previously a class action lawsuit that closed in 2022 to cover this issue. This needs to be a recall or further action needs to be taken before this leaves someone stranded in a dangerous situation - likely when the auto start stop can't restart a vehicle at an intersection due to rough start.

Our 2018 Chrysler Pacifica had a check engine light come on and we immediately took it to get it checked out. The mechanic said that it had a cylinder 5 misfire that would require a new engine. Our Pacifica only has 68,000 miles on it. The vehicle never over heated and we did routine maintenance by the manufacture recommendations. Our extended warranty is denying the claim due to coolant leaking into the cylinder. We have never had any issues or overheating. This looks like a faulty design. We have been told this is a very common thing in Pacifica's from the years 2017-2021. I would like someone to please investigate the engine issues in the Chrysler Pacifica.

The head gasket appears to be leaky. Misfire in cylinder 3. routine fluid maintenance and never over heated. Appears to be a common issue with this engine.

Significant leak from the oil filter housing underneath the intake manifold plenum. Upon inspection, one ore more seals of the housing appear to have failed.

PCV valve failure. There was oil leak outside. When taken off, there was oily gunk inside. When shaked, it was obviously completely stuck. I took out and cleaned it thoroughly.

Water pump is leaking with white smoke came out from the engine bay under hood. I immediately checked the reservoir and it was empty. I took pictures and consulted with my friend who is a mechanics who confirmed the findings being due to water pump leak. I confirmed with a pressure test. Had I not noticed, it would’ve listed to other serious problems.

VVL solenoid gasket and O-rings failure in bank 1 and bank 2. This led to significant amount of oil seeping over time on other engine bay components.

Persistent white smoke from the exhaust suspecting coolant leak concerning for blown head gaskets.
