I have a 2018 Rogue S, it is a CPO, bought it back in January with 41,000 miles on it. The Nissan dealer added about $2,000.00 for the extra CPO warranty but it was still a pretty good price overall. There is also a maintenance plan came with it that I will probably never use, it is for tire rotations and oil changes at the dealer for the next 4 years. When I bought the car the dealer changed the oil with their bulk conventional 5W30 and a quart of some kind of "oil cleaner" snake oil I never heard of before. The oil level was about an inch past the full mark on the dipstick when I brought it home. I changed it that afternoon with 0W20 STP and a new OEM filter.
The car is really clean and in very good shape, it was a local trade from Orlando. It's a nice car, looks good and gets good MPG but also will get up and go If I need it. The only thing I don't like is the CVT. It has a vibration to it at a couple points in the middle of the power band. It's ok at lower speeds and when cruising on the highway but if I am accelerating but at constant speed around 42 mph it has a vibration I feel in the console and steering wheel. Let off the gas or speed up and the vibration goes away. Nissan has said it is normal and is how the CVT is designed. I never noticed it on the test drive and now I am learning to live with it. Other than that it's a very nice car with a good warranty. I hope I never need to use the warranty.
My wife has a 2014 Rogue she bought new in April 2014. It has 71,000 miles on it now, and has never needed any repairs except for a battery and one time so far replaced the front and rear brake pads and resurfaced the rotors. I change the oil and rotate tires on both cars myself every 6 months/5,000 miles and I save every receipt. I get the CVT fluid changed in her car at the Nissan dealer every 30 to 35,000 miles, brake fluid flush every 3 years. I had a brake flush and CVT fluid exchange done at the dealer on my Rogue when I bought it. Neither car is due for a coolant flush yet, Nissan says that is due every 7 years. My wife's Rogue has the CVT vibration too, just not as bad as mine. I think that might be because the suspension in mine is still pretty firm, not yet really broken in like hers.
The Rogue is a pretty good car, it was the best price I could get on a SUV type vehicle. The ride quality is comfortable but very firm, which my wife and I both like but it does not ride like a pickup truck either. The a/c works great, and will freeze you out in no time. We live in Florida and the few times we have used the heat it also worked very well. All the buttons and controls on the dash are very intelligently laid out and have a quality feel to them. The seats, door panels and all of the interior bits all seem to be very good quality. The backup camera is one of the best I have ever seen in any vehicle and the radio works with Android Auto and Waze. Buy a good quality USB cable if you plan on using Android Auto, the cheaper ones do not work very well with the Nissan radio. I had a lot of skipping and intermittent cell phone/Pandora connections with a lower quality cable. Mine has the blind spot and lane departure warning system on it, it is a really good feature especially when driving in traffic. It has saved me a few times already.
Nissan is a pretty good car for the money. From what I have done on my wife's Rogue and my own, I can say they have not been a nightmare to work on, but I am no technician either. I can't really say one way or the other about longevity, other than my wife's car is over 6 years old now, is still in great shape and has only needed a battery, one set of front and rear brake pads and regular oil change/tire rotations, regular fluid flushes and a few air filters and cabin filters. Luckily I am still able to do a lot of that myself.
