    First, I had camshaft related error which turned out to be a bad intake camshaft on bank 1. The Camshaft, all rocker arms, lifters, camshaft adjuster and all VVL actuators have been replaced with genuine mopar parts. 3 weeks latet, the head gasket on bank 2 failed, caused coolant to leak into the cylinder. The van has 89k miles, very clean and always maintained on time.

    Head gasket blown! Vehicle is under 100k miles, never overheated, service properly maintained. When researching symptoms, I discovered I am one of hundreds if not thousands of 2017-2018 model Pacifica owners who have suffered this issue. Heads are known to be faulty and Chrysler will not address the root of it. It's very possible this could lead to a locked engine while driving and cause harm to driver or others.

    We had to replace both head gaskets last July with only 70,000 miles on the vehicle. The repair cost was $4,600.00. This August, we started experiencing coolant leaks again. We discovered the cylinder heads are warped now. This was checked last year and it was not the main issue then. It is extremly disappointing that now at 80,000 miles we are looking at another $5000.00+ repair. There needs to be a recall on the engine cylinders and head gasket.

    The head gasket failed at 89,000 miles. The engine gave P0305 Cylinder 5 misfire codes and would run rough causing difficult to drive in standard traffic flow. There are borescope pictures of coolant in cylinder 5. We stopped using the vehicle until the repair can be completed. This appear to be a WIDESPREAD problem for 2017-2019 Chrysler Pacifica which are numerous on the road and could be hazardous if these vehicles failed on regular roads and highways. See [XXX]…

    This report is for a 2018 Chrysler Pacifica with 90,100 miles. The check engine light came on in July 2026. It was a cylinder 5 misfire. The spark plugs and ignition coil were replaced. The check engine light came on again about 2 weeks later (cylinder 5 misfire again), was dismissed and reset by the shop, and came on again about 2 weeks later. This time, the shop diagnosed cylinder 5 misfire due to "cylinder 5 is leaking coolant into the cylinders." They quoted $12,000 for…

Independent shop confirmed issue and replaced head gasket. Problem appears to have re-occurred after 2 years and 20000 miles with similar indications. Same…

    While driving, the vehicle unexpectedly shut off without warning. The engine stalled while the vehicle was in motion, causing an immediate loss of acceleration and power. This created a serious safety hazard in traffic. The issue is consistent with the condition described in Safety Recall U01 for 2017 Chrysler Pacifica vehicles involving the Powertrain Control Module (PCM). However, this vehicle's VIN is not included in the recall despite exhibiting the same symptoms.
