2019 Chrysler Pacifica Engine Problems

We bought our brand-new Chrysler van in 2019. On [XXX] the oil filter housing needed to be replaced due to cheap manufacturing parts. It cost us $918.78. In October of 2025, we were experiencing some shaking in our van. Upon investigation, it was diagnosed with a blown head gasket. The repair was estimated at $3000 - $4000. The mileage on our van was a little over 93,000 miles. We were meticulous with the maintenance of our van. This, according to Chrysler Pacifica owner online forums, is not uncommon. There is a general outrage at the obvious manufacturing error. Is there any class action lawsuit ongoing? Is there any recourse available? Chrysler should pay out due to their shoddy work.

While driving light came on that car was hot. Immediately pulled over and had the van towed. Was told the head gasket was blown which damaged the engine. Engine now needs to be replaced. Cheapest estimate has been $9,000 at a dealership, van isn’t even paid off yet. My 5 children were in the car when this happened I was afraid the vehicle was going to stop in the middle of the rd. No other warnings or anything. Also when we first purchased van was idle and then go silent like it’s supposed to we have noticed it doesn’t even get quiet anymore. Very disappointed family of 7 with no way to have our van repaired.

The contact owns a 2019 Chrysler Pacifica. The contact stated that while driving at 55 MPH on the highway, the A/C vents started blowing cold air; causing the vehicle to become extremely cold. There was water coming from the wheels. There were no warning lights illuminated. The contact parked the vehicle and noticed that the radiator was cracked. The contact who is an independent mechanic, determined that the torque on the radiator caused the radiator to crack. The vehicle was towed to the local dealer, where it was diagnosed that a radiator replacement was needed. The vehicle was not repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The failure mileage was approximately 99,970. The VIN was not available.

The head gasket leaks, full engine replacement is recommended. No accidents, only 79k miles on the engine.

Van has 55,000 miles on it. Not overheating but noticed coolant reservoir keeps needing to be topped off daily. Also, just received check engine light code for cylinder 5. Shop diagnosed as head gaskets and now need an engine replacement. Absolutely unacceptable for a vehicle with such low miles.

The 2019 Chrysler Pacifica limited with 3.6l Pentastar engine had a check engine light come around 90,000 miles. The vehicle would suddenly lose acceleration power without warning, especially while getting onto the freeway. It was found that there is a known issue with the 3.2 and 3.6l Pentastar engines where the camshafts begin throwing metal shavings into the cylinders. The issue first presented itself as a cylinder 6 misfire with error code P0306. After replacing the spark plugs, coils, and VVT solenoids, the problem continued until the metal shavings were discovered. The design flaw of the engine causing the camshaft to produce metal shavings into the cylinders that lead to the sudden loss of acceleration is a major safety concern.

The check engine light came on. The day it came on, when starting the vehicle, it started shaking while in idle and when initially driving. The same day I had the engine read and a cylinder 6 misfire came up on the report. When I began driving, the car was shaking and it felt like it could stop abruptly which could have caused an accident. Yes, it was inspected and it was diagnosed that the head gasket is blown. Yes, the check engine light came on. It should be noted that when my local mechanic diagnosed the problem, two other Chrysler Pacifica's and two other vehicles with the v6 engine have the same issue.

I am the mechanic that was hard to work on this vehicle and I am feeling this out for the customer but I am submitting it in my name . Vehicle has code p105c and p0303. The first code is pending permanent and stored, it is saying the intake valve is stuck in a low lift position. The second code is for cylinder 3 misfire. We had the coils switched over from cylinder 3 to cylinder 5 and made sure that the wiring was not damaged and the same code keeps coming back for that cylinder as well as the p105c. It causes the vehicle to start shaking while going down the road almost causing an accident. There is a recall on the 2020 Pacifica having the same code but there isn't a recall on the 2019 which has the same engine.

Around 79,000 miles, my 2019 Pacifica experienced check engine error codes. Upon diagnostics by a repair shop, found that the engine coolant was leaking into the engine due to a bad head gasket and that the engine cylinders were damaged and the only repair is a full engine replacement. The car has been maintained and received regular oil changes and should not fail in this manner at less than 80,000 miles. Reading through various forums I see this is a known issue with the 2017+ model year Pacificas

The transmission shifts/jerks hard and hesitates/struggles to accelerate at times. It has even shutdown numerous times while I was at a traffic light.

Engine was running low on coolant due to malfunction of heads Computer did not warn me or temperature senser gage showed normal Engine needs replaced now

Got on freeway on ramp. About 3/4 of a mile later, warning came on “Stop Safely, vehicle will shut off soon” - red turtle appeared, and service engine soon light came on. 1. Transmission - it is at this point, but part has been ordered to replace 2.Going freeway speeds (73MPH) and had to immediately slow and pull over with little warning. If the traffic would have been heavier, there is a good chance a collision would have occurred. 3. Yes - it was taken to a dealership today (5-9-24) and they indicated it is a transmission issue, and are ordering parts to correct this issue 4. No warnings prior to it coming on when I was driving.

Engine failure; engine light P0306 error, cylinder 6 head gasket blown. Mileage 62k, Year 2019. Yes, vehicle is available for inspection upon request. The vehicle was a danger to my family and others, as it unexpectedly overheated on the freeway, and there were no known engine problems to that point. I drive a minivan for my family (2 parents and 3 children), and I am also a carpool parent for two other children, and regularly drive children to and from school, twice a day. An engine failure with no warning is a massive danger and a huge compromise to safety to the families involved and those on the road around us as it occurred unexpectedly on a freeway, at freeway speeds. Upon inspection by a mechanic, it was discovered that the vehicle had no coolant, the coolant had been leaking into the engine, causing mis-firing of cylinder 6, and the car overheated due to low coolant levels; the cylinder head gasket and exhaust manifold gasket was replaced. Additional engine components in poor condition and also replaced: all spark plugs, coolant housing, timing chain tensioner A and B, front crank shaft seal, timing cover gasket, oil filter housing, and rear engine mount. Additionally the cylinder head needed to be resurfaced. The vehicle/component has not been inspected by the manufacturer, police, or insurance reps.The vehicle and faulty components have been inspected by a mechanic. Leading up to the engine failure, there were no warnings of low coolant, as there is no coolant sensor; the engine light only turned on the day of engine failure; and a few days before engine failure, the only symptom observed was slightly stronger idling than normal, almost imperceptible.

Leaked coolant into cylinder 6 at 47,090 miles. Head gasket replaced under warranty by dealer on 4/26/22. Currently experiencing cylinder 6 misfire, rough idling and using 16 oz coolant per month at 66,683 miles. Dealer recommended new head gasket and new head on 10/20/23.

The vehicle was repaired; however, the failure recurred. The vehicle was not repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 121,419.

BLOWN CYLINDER HEAD GASKET ON THE RIGHT SIDE.

STOP/START FUNCTION IS A HAZARD. WE HAVE ALREADY HAD IT REPAIRED ONCE AT A DEALERSHIP WHERE WE NEEDED 2 NEW BATTERIES. 2 WEEKS LATER, IT STARTED DOING THE SAME THING AGAIN - SPUTTERING WHILE DRIVING, AUTO STOP START NOT AVAILABLE. HAD TO JUMP START. IT TURNS OFF WHILE DRIVING SOMETIMES IN THE MIDDLE OF THE ROAD.
