Thank you for this, Hannah, but three of the four TSBs apply to the Hybrid 3.6L V6 and, at least to my knowledge, that engine has not suffered from the same head gasket and cracked block issues that the ICE version has. The one TSB that does apply to non-hybrids does not address the common P0303 misfire with resultant engine failure issue.To follow up our previous message, here are some relevant TSBs below that may prove useful. We advise you contact your nearest Chrysler dealership to confirm whether these apply to your vehicle. If you have any additional questions, please send us a private message so we can dive into your particular concerns.
Thanks everyone!

Not necessarily. Do you mean bubbling in the coolant reservoir after the engine is turned off? If so, it could be the level of your engine coolant is well below the "MIN" mark on the reservoir and air has gotten into the system. Some who have reported smell of coolant have traced the coolant leak to a crack in the plastic oil cooler near the top of the engine under the intake plenum, sometimes caused when a owner or technician overtightens the cap to the oil filter during an oil change. Letting the engine coolant drop too low can result in overheating, and that's when things start sliding downhill.I have 2017 with 87K miles on it. I haven't received any error code yet, but I do smell coolant in the morning, and bubbling in the coolant reservoir when the car is cold. Do I have a blown head gasket as well?
The bubbling in the coolant reservoir only happens when the car is cold in the morning. After the car is warmed it would stop. I will check on the plastic oil cooler and see if there are any cracks. Yes, I have been filling with MS12106. I will schedule a time with the dealer to take a look.Not necessarily. Do you mean bubbling in the coolant reservoir after the engine is turned off?

If you need to add coolant, be sure to use only certified coolant as shown on top of the reservoir cap (I think it is MS-12106). Check your owner's manual. It will tell you that using the wrong coolant can cause engine damage. You can't go wrong if you buy genuine Mopar coolant directly from a Chrysler dealer.
In the meantime, I'd suggest you get your Pacifica into a service facility right away to find out what indeed is causing the smell, and to possibly prevent an even bigger issue from developing.
Thank you for posting, and good luck. Please let us know how it goes.
Dang. Is this the first 2019 we have had on here?Please add me to this list.
2019 Pacifica with 83k miles. Always serviced with Chrysler, and actually just done 1,500 miles ago. While driving, we received an alert for the car getting hot. Pulled over immediately and then had it towed to their shop. Initially told the oil cooler failed, then they performed a leak down test, cylinder 3 at 85%, stating we have a blown head gasket. They further investigated and reported the block was warped too. Recommendation is full motor replacement for a cost of alittle over 15k. No other codes in the computer about any issues. Have a case open with Chrysler customer care, but dont have high hopes.

I’ve asked the same question but they haven’t been able to give me a good valid reason. Same thing with the overall issue. I asked what the main root cause of the car over heating was and the head gasket blowing. Nothing, other than some parts just go bad. Searching for a motor now, hopefully I can find a good price on an oem or remanufactured one.Welcome to the forum, BlueNinja. I have added your username to the list. Yours is #125.
Just curious. Did they say anything about why the oil cooler failed? Was it cracked?
Thanks for the info. Only way we are going to get the real reason is through a subpoena of Chryslers internal documents.I’ve asked the same question but they haven’t been able to give me a good valid reason.

The reason I asked was because you stated your Chrysler dealer serviced your Pacifica 1,500 miles ago. Made me wonder if they changed the oil & filter and, if so, if they cracked the oil filter housing by tightening down on the filter cap too much. From my understanding that would cause a small leak of coolant that could go undetected unless one were to open the hood and check the coolant reservoir every few days. Sorry; just thinking out loud here.I’ve asked the same question but they haven’t been able to give me a good valid reason. Same thing with the overall issue.

I know the oil filter housing is top mounted, but even if it’s cracked, where would coolant leak into the motor from? Is there an area coolant runs next to that housing?The reason I asked was because you stated your Chrysler dealer serviced your Pacifica 1,500 miles ago.

Others here know the engineering much better than me, but I think the scenario goes like this: an oil change technician torques the oil filter cap on so tight that it cracks the housing connected to the oil cooler; that allows a bit of pressurized coolant to constantly escape the system onto the top of the engine; the engine warms up such that the escaped coolant is basically evaporated, thus no leak is detected; meanwhile, as the Pacifica is being driven day after day, more and more coolant escapes the system such that the coolant reservoir runs dry; eventually there isn't the proper amount of coolant needed to circulate through the engine to keep it at optimum temperature and the engine overheats. Or something like that.I know the oil filter housing is top mounted, but even if it’s cracked, where would coolant leak into the motor from? Is there an area coolant runs next to that housing?
Now that you mention the oil cooler, the service rep initially stated the oil cooler caused the issue, and he stated oil was pouring out of the oil cooler. Maybe its possible that occurred. Now throwing blame on the dealer and proving it will be the difficult part. It’s still at the dealer, I need to get down there and inspect it myself around that area. I’m trying to locate a motor, as I plan to either the swap myself or hopefully have someone I know do it, and hopefully at a decent price, vs what they quoted me.Others here know the engineering much better than me, but I think the scenario goes like this: an oil change technician torques the oil filter cap on so tight that it cracks the housing connected to the oil cooler; that allows a bit of pressurized coolant to constantly escape the system onto the top of the engine; the engine warms up such that the escaped coolant is basically evaporated, thus no leak is detected; meanwhile, as the Pacifica is being driven day after day, more and more coolant escapes the system such that the coolant reservoir runs dry; eventually there isn't the proper amount of coolant needed to circulate through the engine to keep it at optimum temperature and the engine overheats.

I wonder what will become of your old engine. You still own it, so can you trade it in on a new engine? (I honestly have no idea of such matters). If you still have access to the old one, can the old oil cooler be removed and inspected?Now that you mention the oil cooler, the service rep initially stated the oil cooler caused the issue, and he stated oil was pouring out of the oil cooler.

You're #126.1st owner of a 2018 Chrysler Pacifica less than 80k miles with cylinder 1 misfire, check engine light on, blown head gasket. I hope Chrysler will take some ownership with a recall on this if there are this many people having the same issues! So expensive and frustrating!
