Our vehicle is always kept in a garage and rarely parked outside for extended periods of time (not a vehicle used for transportation to and from work on a daily basis). We had our check engine light come on. This resulted in us using our second vehicle for several days before determining days later that the check engine light was still on. We took it in and they said the stored code was for a small evap leak and said it was likely due to cold temperatures and ice build up around the edge of the vent that blocked the flap from opening. As mentioned, this vehicle was in a garage for several days leading up to the check engine light appearing and for several days after the initial appearance. When I asked the dealership doing the repair what we could do to prevent this from happening again they suggested we avoid having the vehicle parked outside in the cold. This seems to be an issue that should be handled by Chrysler as opposed to me as the consumer and causing me to pay $217.31!

Our 2018 Pacifica after only 77K rough miles has a blown gasket and a misfire in cylinder 3. The safety concern is that my family bought this van and are the original owner with the safety standards in mind. We have a 6 year old and a 3 year old. we have had this van since our first born was born. a possible blown engine is a safety issue and wouldn't expect this with such low miles. Vehicle was inspected by the dealer and coolant was found in cylinder 3. the only indication that we had got was the check engine light coming on and then after we made sure the gas cap was on, we ran some fuel cleaner to see if it was a fuel injector issue and the light went away. when my wife used the key fab to start the vehicle, it wouldn't start and the engine light appeared. we took it to the dealer at that point once we had autozone scan the codes. we then learned it could be a gasket or needing plugs and wires replaced. Dealer reviewed and used a camera to see that there was coolant leak. this issue continues to impact many of these vehicles and nothing is being done.

While driving on the freeway, the van suddenly started to -??drag-?? and alarm that the start/stop system was unavailable. I was barely able to pull off the freeway before the van completely stopped moving and would not start up again.

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.

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.

On [XXX], my vehicle produced a large red wrench and a turtle warning on a busy highway and I was forced to pull to the side with my [XXX] son in the car, as the vehicle lost motive power. It was towed to the dealer and after several days, they told me the issue was due to normal wear and tear in the transmission. I had to escalate to a service manager to even get a diagnosis after 5 days in the shop. I believe my transmission issue is due to a failure of the fix implemented in the 03A/NHTSA 23V-010 recall. It has been documented that the software update did not fix the issue. My vehicle experienced the exact series of failures described in the recall. Chrysler is refusing to fix my vehicle, even though they had extended the warranty on my Pacifica to unlimited miles/unlimited years because of all of the transmission issues the model has experienced. I would appreciate it if someone could look into this and Chrysler's unwillingness to stand behind their products and provide fixes for their recalls that work.

The engine was unresponsive and made it difficult to pull into the oncoming traffic. We found out the head gasket was blown and it finally just shut down. Then after we fixed that the lifters and heads were gone even after we had the heads milled and got new gaskets and other parts amounting to $11000 so far. We have this car for two years and we have put less that 5000 miles on the car.

There was a rough idle and tje the check engine light came on, idle smoothed out and the the following week the check engine light started blinking and the van started to miss and then drove rough. Then I took the van to dealer and they said it seemed that I have a cracked head after I received engine code for misfire on cylinder 3... sounds like this is a growing issue for this van and engine type.. Thank You for any help with this situation.
