Yes the V6 is definitely the way to go. I have a unique perspective because I own the I4 2011, but my mother owns the 2015 V6, which I have driven well over 20,000 miles on her V6. The v6 is better in everyway. The only thing I like about the I4 better is that it is slightly easier to work on since you have a lot more room in the engine bay. But even the gas mileage is almost the same. I average around 23.8 MPG and she averages around 22.1. Pretty good considering you are almost doubling the horse power.

Thank You for your input, you do have a unique perspective.. The V-6 is the engine of choice. But agree about less room to wrench on it.

I saw a you-tube on changing the V-6 spark plugs. Wow !! Gotta remove the intake manifold. That was a surprise. I'm trying to learn all I can about these vehicles & make a good decision in selecting one..

2015 Terrain 85,000 miles bought new

Replaced windshield wiper motor a few years ago (that is a whole other story)

Front and rear brakes and tires (almost 2 years ago)

Rear shocks last year

Current issue Camshaft Position Actuator Solenoid Code P0013 hoping its covered under my power train warranty.

Love the car otherwise, its all that I need.

2012 2.4 terrain. 90k miles. Slight rattle in front end I need to look into. A rare stall in reverse on a cold start (just started happening, less than a handful of times) occasional throttle body cleaning (maybe twice a year at most and was never terrible) I started changing oil closer to 3k miles because it seems the closer I get to 5k miles, the faster it burns (maybe 1qt at 3k but an easy 2 at 5k, maybe oil is getting diluted with fuel?) Motor overall is smooth and quiet, looking into replacing the timing chain asap, this forum has me paranoid as all h$!!
Overall I have no complaints, knock on wood I got lucky with mine from what I've read. Oil has always looked and smelled fine. car overall drives well, I will say eco mode makes it run like a pos so I never touch it. I had a few misfire codes in the winters but was also using eco mode intermittently, stopped using it and issue went away.

Good to hear, If your oil ever smells like gas I'd be changing it ASAP.
