The check engine light came on, we took it to a auto zone it showed cylinder 2 misfire. We repaired the spark plugs and spark plug housing units. The check engine light was still on after that. So we took it to a shop had them run a diagnosis again and the same cylinder 2 misfire came back. They took out and replaced all the spark plugs and housing units again and even replaced the fuel pump. Reset the check engine light and it still came back on. Upon checking the internet for possible issues, I found it was reported from over 100 Dodge Grand Caravan owners this same exact issue. After doing the tune up exactly as we did replacing the same parts we have replaced twice they have all still had the same issue. This has been found that it is an engine cylinder that has gone bad. I do not see how this cannot be considered a recall when multiple owners have had the exact same issue. …
My 2018 Dodge Grand Caravan will not turn the starter when I turn the key intermittently, especially when the temperature is hot. The key has to be turned on and off many times before the starter engages and the engine starts. The engine will turn off while driving the van on the highway which causes the power steering to go away. The van must then be shifted to neutral and cruise to a stop so it can be re-started after many tries as explained above. This is very dangerous because if you are on interstate in fast lane with cars behind you, it causes vehicle to slow down because engine stops without brake lights being engaged that could cause rear end collision and makes steering very difficult. This usually happens at least three times in succession before going away for this individual trip. There is no warning when the engine cuts off while driving. …
I have a 2018 Dodge Grand Caravan I bought used from a CDJR dealer. I went on a 2,500-mile road trip in July 2021. The engine began running rough for about the last 500 miles. When we got home there was about 63,000 miles on the vehicle. I took it to a local mechanic at home in August and he said I had bad fuel so he put in a fuel treatment and had me fill up with premium fuel one to two times. This seemed to help only marginally. A month later I took the van to another mechanic and he determined that there was a misfire in cylinder #2. He performed a relative compression test and said the engine will need to be disassembled and inspected. He called a local dealer and found the warranty was 5 years/60,000 miles. He suggested I call my dealer because this shouldn't be happening even outside of the warranty. I did. They offered no solutions. Very frustrating.
My cars engine light came on. First I thought it's was after a fill up of gas. Then it went off. Days later I went to go home from work and the car just wouldn't start. I had to have it towed- the mechanic stated it's always a problem em with dodge caravans it's the engine. I towed it to my normal mechanic which replaced the battery and lo and behold engine light is on. Took it to the dodge dealership and it's a cylinder head that needs to be replaced. This car is 4 years old, just at 75,000. In the ordinal owner and maintenances as suggested by manufacturer. This is unsafe and I cannot drive my children around in this vehicle. This is a known issue with these. My mechanic had another one in his shop with the same issue, but only 45,000 miles. I cannot drive this car, as it will continue to crack and cash a fatality with my children in the car.
My 2018 dodge grand caravan had a check engine light come on indicating a cylinder 2 misfire. I took it to my dealership to find out If it was just the spark plugs. After multiple days of back and forth calls they informed me it was the cylinder head it's self and that the cost would be around $3700 to fix if warranty chooses not to cover the repair. My child is wheelchair bound and we have been forced to cram into a small dodge dart until warranty department clears the repairs. I have already turned in all the service paperwork showing all services have been done on time. It only has around 75000 miles on it, it's never been in an accident, and has always been maintained. After extensive searches on the internet it has been an ongoing issue with the 2013 -2018 dodge grand caravan models cylinder heads.

Check engine light came on. Vehicle would shake and have trouble accelerating when I put my foot on the gas pedal, it was worse if gone above 45 MPH. Vehicle was sent to mechanic for diagnosis and repair. P0302 code was read for #2 fuel cylinder misfire. PCV valve, Coil pack, All spark plugs, & Fuel injector were replaced. Check engine light is still on. Vehicle cannot be operated under mechanics safety recommendation. There is still a cylinder 2 misfire. Car can stall at anytime if operated.
