My Journey is a 2013 6 cylinder and it is the worst car I have ever had. I doubt I will be going back with Dodge again, I am looking at Kia's. I have had a problem with this car from the very beginning and I only have 3600 miles on it. It has been back to dealer 4 times and they don't know what the problem is. Today we are taking it back to a local service dept. for them to see what may be the cause of this vibration. The other dealer said it is the "ECO MODE" I don't buy it. Good luck with your car.
