NHTSA Complaint #11517125 — 2017 CHRYSLER PACIFICA

On the highway the temp gauge went all the way to hot and then immediately went back to normal temp. We pulled over on the shoulder of the busy highway and let it sit for a bit, and it never showed hot again and stayed in the normal range. Drove 5 more miles to home and checked the coolant and it was almost empty. We filled it and kept checking it every day. Had to add more every other day till we could get it in to a mechanic. a few days later the engine idled rough and check engine light came on. Took to mechanic and he said code P03305 showed as a mis fire in cylinder #3. He replaced the coil pack and spark plug and did a pressure test on the coolant system to see if he could find the leak. He said I could find a leak and bet that it was a crack head leaking coolant into cylinder #3. Ran better for another week or so while we were waiting for our appointment at the dealership to have them look into where the leak was. 2 days before our appointment at the dealership, we had the same rough idle and code P03050 saying misfire in cylinder #3. I replaced just the spark plug and then took it to the dealership. They misdiagnosed the problem as the reservoir was leaking. After they replaced it, we were back 2 weeks later with the coolant still leaking somewhere. They eventually found the head was warped due to excessive heat and coolant leaking into the #3 cylinder. This van has around 73,000 miles on it. After researching, it seems Chrysler has a faulty engine that is causing people to break down on the highway which is not a safe place to be. Please look into Chrysler's faulty 3.6 penstar motor problems.
