2018 CHRYSLER PACIFICA Complaints

Failed cylinder head (misfire p0304). Need to have engine rebuilt or replaced. Also had oil cooler failure, losing coolant and oil. 71k miles, just over the 60k power train warranty. Need dealer to help fix but they are booked for next 3 months. Car initially cut out on the road in traffic after auto start stop, was scary and safety risk with family including kids onboard. Confirmed with independent mechanic, but also going to dealer as it is specialty work for that engine.

Coolant leaking into cylinder 4 causing a misfire and engine overheating resulting in blown head gasket. Vehicle had only 50K miles at the time; however problem was not diagnosed until just after 5 year mark (powertrain warranty expiration).

Suddenly our Pacifica would not start and started cycling through over a dozen error messages. We were finally able to get the vehicle to start and took it to the dealership. They confirmed that the star connector needs to be replaced. After looking at many forums, this appears to be a fairly common issue among the early hybrid pacificas, to the point that I felt I should report here, especially given the recalls that have already happened due to the electrical system in the car. We just got the last recall done in August and already we now have a ~$1000 bill to repair the electrical system again. Please have someone look into how many of the pacificas need this particular connector replaced given the prevelance of people with the same issue online.

At around 84000 miles the engine light came on and the van started spattering and when you start it. The first place I took it to said it was cylinder 6 was misfiring and they replaced the coil and spark plug. The van check engine light came back on and it started to overheat so we took it back in and the coolant was empty. They refilled it and I got it into the dealership and they found that it was the head gasket so they placed it. Upon picking it up the check engine light came back on and they replaced a cam shaft sensor.

What component or system failed or malfunctioned, and is it available for inspection upon request? The shifter module fails or malfunctions and it put the vehicle in park. All the electronic controls in the vehicle malfunctions even when the vehicle is driving like the ABS, displays, throttle, ADAS and all other controls How was your safety or the safety of others put at risk? The vehicle suddenly starts throwing the warnings while you are driving - sometimes in the freeways, it also jerks, throttle and other controls and displays goes blank, you are not sure even if the emergency flasher is activated Has the problem been reproduced or confirmed by a dealer or independent service center? Yes Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? It started almost 2 years ago in Dec 2021 when the check engine light first came, dealer tried to fix by replacing the 12 volt battery but the problems started slowly and in August 2022 disabled the vehicle completely. The vehicle had been with the dealer most of the time since then and its still not fixed as of today

Pull into garage with <1% hybrid battery. Pressed the power button and the Pacifica threw an error about servicing the transmission and it would not disconnect the power to shut off the vehicle. Opened the hood and disconnected the 12v battery to complete remove electric from the system. The van completed a shutdown. Reconnected the 12v battery and closed the hood. Car returned to working conditions.

We could not locate an active coolant leak for almost two months (brought to several mechanics.) Added dye to the coolant and it showed in the oil. Waited over a month for an appointment with the dealership and was finally told that it was a bad Head/Head Gasket, Oil pump and would also need a new catalytic converter etc.... It is apparent from the chrysler forums that this is a VERY common problem. #5 cylinder, bad coolant channel design leading to engine failure. Even the mechanic at the dealership said (ON VIDEO) that this was a common issue. Chrysler is WELL aware of the issue but refuses to redesign or assist customers when the failure occurs. This is CLEARLY a safety issue that begs for a recall.

Engine sputtering, engine light came on P0303 cylinder 3 misfire. Light would come on and off every couple of days. Diagnosed with a blown head gasket at ~51,000 miles.

My van experienced sudden misfiring when I tried to start it. To address the issue, I took the van to the Chrysler dealership in Buford, GA. After their assessment, they informed me that cylinder 3 had a crack, and it necessitated the replacement of the entire engine. They provided a quote for this repair, which amounted to $13,000. I've been diligent in maintaining my van, regularly checking the oil levels, and there were no warning signs or indicator lights until the check engine light came on when the misfiring issue began. It's worth noting that my van only has 81,000 miles on it. While researching this problem, I came across a forum where numerous individuals shared similar experiences, indicating that this kind of catastrophic engine failure shouldn't be so common.

We began having major issues with our van in October 2022. There were numerous incidents of loss of power and sudden increase in temperature gage. We kept fluids checked. Kept oil changed on time. We reported this to the dealership multiple times before they agreed to fix under warranty. Even after fixing factory recall (which we were charged for by the dealership) and then replacing batteries, we continued having issues with loss of power and surge in temperature gage. July 8th of 2023 engine light came on and temperature gage shot up, van stalled at the intersection. I had My self and FIVE kids in the car. This was accompanied by a sudden loss of fluids. We had the van taken to another repair shop who then told us the head gasket was blown. This happened just 4 miles after our warranty lapsed. We had to have the entire motor replaced out of pocket. More than $8,000 in repair costs so far and the van I still making noises and not driving correctly.
