Should I purchase?

I own a 2014 with the V6 in it and in my opinion the 4 cylinder really isn't a good option in them because they are a heavy truck. If you live in a very flat area, it might work but the 4 cylinder has to work much harder to move that vehicle, and that alone makes it questionable to me. As far as reliable, I wouldn't class anything made in the past 10 years as reliable unless it was a Toyota or Honda and even those are getting to be less than stellar. I would also try to avoid as much of the electronic options as possible. While they sound fun to have the failure rates are very high as are the repair prices. The Bluetooth hands free stuff seems to be okay, but a lot of the ADAS items are failure prone. I just replaced a radar unit in a Ford and the part alone was $1,200.00 and you need another $10,000 dollars in special tools just to align it. It's job? Allows you to set the cruise control so it tracks the speed of the vehicle in front of you and warns you if they are slowing fast. I think I'll trust my eyes for that. However, at the end of the day it will be your decision, I would say to go visit https://www.dodgejourneyforum.com/ and read and ask there.
